The electrical layer of an attachable VARIO keyboard translates user
keystrokes into data that can be transmitted through standard wired or
wireless data transfer protocols. This layer consists of a keyswitch
assembly configuration mechanically coupled to the keytop assemblies,
and a unique flexible multipleated printed circuit harness with an appropriate
electrical interface for the specific client host product. The multi-fold
harness configuration at the base of the keyswitch assemblies minimizes
moving harness components. The VARIO assembly can be configured for any
host standard interface including direct cable connection, IBM PS/2,
USB, Firewire, irDa, Bluetooth, or Wi-Fi, as detailed below:

Key Features of the VARIO Designs
Differentiating features of expandable VARIO keyboard designs are listed
below:
- Adaptability for “building into” OEM opportunities
as an embedded and integrated expandable and contractible
keyboard mechanism, or as a separate, after-market attachable
accessory for handheld devices.
- Protection of comprehensive patent portfolio covering
design and configuration variations for all classes,
sizes, and key layout formats of expandable keyboards
and keypads.
- Design compatibility with low unit cost high-volume
manufacturing, assembly and testing techniques.
- Engineered to minimize stress and facilitate use of
thin light materials.
- All other full size QWERTY keyboard designs are
too bulky, thick, or heavy to integrate into cell phones
and PDA’s.
- Usable in up to three convenient keyboard states of
expansion
- Contracted keyboard state for minimal data entry and
short message service (SMS) for single finger input “on
the run.”
- Fully extended mode for
- 100% full size touch-typing keyboard for a familiar
tactile-feedback experience comparable to a desktop,
when incorporated in a handheld or mini-notebook PC,
and
- for larger, user-friendly keyboard areas for QWERTY
thumb keyboards used in smartphone and PDA phone devices,
and
- for increasing available phone keypad area by approximately
100% to enable stowing under display housing in a “micro-size” styled
form factor.
- Intermediate expansion of keyboard for more convenient
and accurate message usage in limited space situations.
- Superior tactile feel with natural feedback in full
size expandable QWERTY keyboards.
- Full pitch (space between keys) both horizontally
and vertically (the same as desktop keyboards).
- Optional expandable variable-width keytops.
- Standard 5-row QWERTY layout.
- Optional 4-row QWERTY layout, if desired.
Future VARIO engineering design configurations will include 1) a keyboard
design with variable-width keys, and 2) a keyboard design that also expands
longitudinally, and will be optimized to target particular OEM market
segments and their end user customers.
- Variable-width keys expand along with the keyboard assembly
to allow increased contraction and expansion. This technique
can allow for more compact designs than normal fixed-width
keys.
- A keyboard design that will expand laterally and longitudinally
provides maximum compaction, particularly for small keypad
designs, employing a special elasticized member structure
that supports two dimensional expansion and contraction.
Customizing, Qualifying, and Costing Reference Designs
and Prototyping Models for Client Product Requirements
RAST’s OEM licensing strategy encompasses the ability to support
client product engineering and manufacturing design projects through
its development engineering design team. RAST recognizes that each OEM
platform and manufacturer has their own packaging and interfacing requirements
and may have their own unique customized product engineering, manufacturing
methodologies, and fabrication process preferences. RAST’s team,
working with the specific business and product objectives of the client,
can provide customized production reference designs of VARIO keyboards
and keypads for cost-effective embedding and integration into various
handheld product configurations and aftermarket accessory products of
OEM partners.
 
In business discussions with potential licensing clients regarding
their specific product configuration requirements, RAST can propose to
provide, depending upon the client’s development and manufacturing
implementation strategies, fully detailed mechanical engineering reference
designs for the keyboard and keypad products, together with CAD/CAM parts
and assembly drawings, appropriate analyses of mechanical design tolerance
testing and fabric stress-strain behavior, description of high volume
production and fabrication processes for components and assemblies, bills
of materials and estimated volume costs for parts and fabrication. RAST
can also propose rapid prototyping models through its professional engineering
team and network of associated supplier and industry resources for specialized
mechanical parts and fabric manufacturing and testing.
As part of the evaluation process, manufacturing partners will need
to understand the materials, cost, and fabrication for VARIO products.
RAST has created specific detailed engineering and design information
from which to produce volume production versions of VARIO keyboards.
This also includes the recommended assembly techniques and associated
tooling and fixture requirements for manufacturing and takes into account
lower offshore labor costs in countries where these handheld devices
are generally manufactured (i.e. China).
Per-unit costing is available for the full size keyboard product with
100% expandable keyboard (2:1 expansion) with fixed key width keycaps,
and will be available for (2), the micro-size keypad, which resides in
micro cell phones and will feature both lateral and longitudinal expansion
of approximately 30%. For integration with client products, certain elements
of an embedded design will replace similar elements of existing products
(e.g., keyboard frame and latch, keyboard backplate, electrical contact
harness), thereby constituting an offset in computing the estimated incremental
cost and weight of the VARIO keyboards.
Manufacturing and assembly production costs are supported by computer
CAD design and process information for the complete keyboard/keypad assemblies,
including housings, expansion mechanism, fabric attachment methods, specialized
tool fixture(s), key assemblies and circuitry harnesses. Therefore, RAST
is in a position to support an OEM’s engineering and manufacturing
teams with cooperative services to develop tooling, fixtures, and production
and assembly methodologies, and costs for a licensee’s specified
product. This data will be sufficient in quality to enable an OEM manufacturer,
after full review, to be satisfied that the product can be manufactured
using the OEM’s own (or subcontracted) processes within a financially
affordable cost range and with the qualitatively acceptable targeted
level of performance and industrial design integration.
Developing Specific Client Configurations of VARIO Fabric/Keyswitch
Configurations and Mechanical Assemblies
VARIO expandable keyboard technologies possess unique characteristics
to enable new product variations in keyboard size and key button “touch-and-feel,” adaptable
to different form factors in handheld cell phones, smartphones, PDA phones,
and handheld PC’s. Thus, device manufacturers incorporating VARIO
technologies have new degrees of freedom in designing for competitive
advantages in style and features. For example, configurations for keyboards
can be developed which stretch from a contracted position to an expanded
size covering the expansion/contraction ratios of approximately 2:1 up
to 2.7:1, while accommodating different keycap size and keyswitch requirements.
For a convenient user friendly smartphone operation, a 7 1/2” QWERTY
thumb keyboard can be packaged in a housing width of approximately 3
1/2”” for storage or single finger operation, while, for
a handheld or mini-noterbook PC, a 10 3/8” full size QWERTY touch-typing
keyboard can contract to a width of approximately 4 1/2.” Expandable
keypads for voice cell phones can similarly allow great flexibility in
the phone form and case design by shrinking the total product housing
to the approximate size of the display without compromising the visual
ease of phone dialing or use of the hidden expandable keypad for SMS
messaging.
Similarly, VARIO designs for keypads and keyboards can have keyswitch
assemblies which can be composed of molded keycap/rubber dome/ keyswitch
assemblies to provide the familiar tactile-touch feedback for sustained
and rapid low-error rate data input operations, or can have membrane
switches using diaphragm snap dome switches for thumb operated dialing
and smartphone applications. Each of these sets of features requires
selection of appropriate fabrics, keyswitches, and production assembly
methods to optimize cost and long term reliability and performance.
All non-fabric materials and components used in the design and manufacturing
of VARIO technology keyboards are widely used in mass production of keyboards
and therefore already meet high standards of quality assurance and testing.
Accordingly, RAST’s efforts for quality assurance and testing are
focused on materials which are unique in the construction of a VARIO
keyboard.
For the critical design of customized fabric/keyswitch configuration
assemblies, RAST has contracted with a senior research scientist in textile
and fiber engineering under an exclusive agreement encompassing all designs
of expandable elasticized keyboards, to provide his expertise, and that
of associates, in the areas of elastic yarn, elastane fibers, fabric
formation and evaluation of textile performance as applied to the development
and production of VARIO keyboard and keypad configurations. This group
is associated with an institution that is an international quality leader
in education, research, and outreach in the science, engineering, and
management of fibers and textile materials and manufacturing technology.
RAST also has, in Los Angeles as part of its local team, an experienced
professional in fabric construction and weaving with a versatile weaving
loom to provide, virtually instantaneously, fabric samples for application
to different client requirements.
This association also provides RAST with access to a broad array of
yarn and fabric formulation and physical testing equipment in research
laboratories, and to yarn production and fabric weaving machines to provide
rapid prototyping and very short production runs of specialty customized
fabrics to best meet differing client product configurations for VARIO
keyboards.
Elasticity of woven fabrics with elastane fibers is enabled by combination
yarns in the weaving process condensing the fabric during the finishing
process by equivalent relaxing or shrinking processes and depends on
the type and composition of the combination yarns, the type and
construction of the fabric, and on the finishing conditions. For
suitable fabrics to be used in VARIO keyboards and keypads, RAST has
studied and performed successful tests and understands the manufacturing
practices, bonding/attachment techniques, fabric and yarn specifications
and other matters necessary to engineer, test and verify the required
performance of the production fabrics.
In order to select or create specific fabrics and keyswitch designs
for a particular device manufacturer’s needs, a process has been
developed which allows selection, testing, and qualification of the particular
fabrics, keyswitch assemblies and their attachment using production materials,
tooling and processes, (e.g., molds, stereo lithography, polycarbonate
and ABS plastics materials, elastane fabrics, attachment methods) to
verify the long term reliability and performance of the fabric/keyswitch
combination. This process is briefly described as follows:
- Based on discussions with the client regarding their
desired specification of form factor and keyboard performance
(size, keyswitch type), yarns and fabric formulation combinations
will be selected for both the warp (non-stretchable direction)
and weft (stretchable direction).
- Sample fabrics will be sent to a certified laboratory
testing facility, which is used by the yarn and textile
industry under a consulting contract to RAST LLC. Both
static and dynamic tests will be performed, according to
established textile industry protocols, to establish life-cycle
reliability and recovery performance. A list of sample
testing eqipment for this procedure is presetned as Appendix
A. To achieve optimal performance, RAST can re-engineer
the yarn formulation (e.g., % elastane core content, covering
material selection) or fabric construction (e.g., weave
density, weave tension) to produce the desired performance.
- Simultaneous with fabric testing, the specified keyswitch
designs (e.g., membrane/diaphragm or rubber dome/molded
keyswitch) will be developed and several samples will be
produced.
- Upon completion of fabric testing and selection of satisfactory
candidate fabrics, keyswitch assemblies will be attached
to the sample fabric using the production methods (e.g.,
sonic welding, heat staking, snap fastening) contemplated.
- The keyswitch/fabric assemblies will then be put through
dynamic and static test protocols to verify performance
of the fabric with switches attached, in terms of appearance,
alignment, registration, and stability of keyswitch positioning
and motion, and absence of keycap torquing.
Satisfactory completion of this fabrication, testing and assembly methodology
will result in the engineering and manufacturing release of the specifications
for the production fabric material and manufacturing, and for the keyswitch
assembly tooling, fixture and production processes.
Design Commonality of Attachable and Embedded Handheld
VARIO Keyboard Configurations
The engineering and mechanical design of a production VARIO expandable
keyboard with fixed width keys and touch-typing tactile feel has been
accomplished with 98% commonality of parts between an attachable wired
or wireless product, and a keyboard assembly which is physically embedded
and electrically integrated within a handheld device host platform. The
basic design has been mechanically engineered to be primarily constructed
as a keyboard subassembly with keyswitches/expansion fabric/contact harness/supporting
rails and backplate. The bottom side of this assembly is shown below:
Figure A
This then integrates with an end-frame support structure (shown in
dashed lines in Figures A and B) which grips the ends of the fabric,
and supports the keyboard subassembly with stability in contracted and
expanded modes of operation.
Only frame assemblies and bezel parts, which make up the end-frame
sections, would be replaced by other components whose customized design
will be dictated by the specific dimensions, industrial engineering criteria
and material composition of the host platform device into which the VARIO
keyboard would be embedded and integrated. A closer view of these host
platform components, also illustrated by dashed lines, in shown in Figure
B1 and B2.
Figure B1
Figure B2
There can be other opportunities for part and assembly customization
to meet particular form factor or product needs, and these would be addressed
with each client..
As examples, Figure C presents a rendering of the top view of the VARIO
keyboard in a generic standalone product configuration. The harness ends
are shown to illustrate one example of where a connector might be attached
for a wired connection. In the event of a wireless or, for example, a
Bluetooth mode of connection, then customizing of the VARIO keyboard
assembly would create the space for the powering battery, battery holder,
battery door, Bluetooth chip mounting and antenna.
Figure C
 .
The VARIO keyboard assembly in Figure D is shown as an example of a
configuration within a generic handtop PC or mini-notebook form factor,
integrated into the host platform with space underneath the keyboard
reserved for electronics such as processor memory, miniature disc drive,
and wireless connectivity electronics.
Figure D
In the following Figure E, the top picture illustrates a full-size
keybaord design integrated with a clamshell smartphone model In such
designs, electronics is generally less complex and could be mounted in
the display clamshell housing, allowing a shallower base for the keyboard.
Figure E
In this lower vew, the expandable VARIO mechanism design is modified
to produce a QWERTY thumb keyboard, where preformed membrane switches
can replace individually molded keyswitch assemblies for simplicity and
size reduction. Alternatively, the host housing design can be reduced
to approximately 4” in width to make one hand phone use much easier,
while housing an embedded VARIO thumb keyboard expandable to approximately
7 ½” for greater user convenience and ease of data input
operations.
In Figure F, this rendering of the basic VARIO keyboard assembly illustrates
integration of the expandable QWERTY keyboard, in full size or thumb
keyboard format, as an articulated attached “backpack” configuration
for a PocketPC or PDA phone. The VARIO keyboard harness ends would be
brought together and merged at the point where the connector to the host
platform would be mounted. The exact type of connection and its mechanical
design is a function of the customer’s requirements.
Figure F
Thus, as illustrated, the detailed mechanical design and engineering
of production models of VARIO keyboards is completely adaptable to the
major configurations of handheld devices on the market.
VARIO Keyboard and Keypad Design Engineering Activities
RAST’s development team has already addressed
many of the keyboard and keypad product design considerations for the
mechanical, electrical and fabric components and their integrated production.
Alternative design considerations have been identified, pursued and evaluated
or rejected to select the most effective solutions. Based on specific
customer product configurations, the result of all this experience can
be applied to optimize the final product design. Among the key engineering
activities investigated and evaluated are:
- Tactile touch-typing selection of force-displacement
methods and components
- Key actuating methods
- Mechanical Interference factors affecting tactile-feel
- Expandable keytops
- Flexible printed material key matrix circuit attachment
configurations
- Key support guidance and framework structures
- Backplate support for keyswitch assemblies
- Row alignment methods
- Fabric placement with respect to the keys
- Fabric anchoring methods for one and two direction expansion
- Methods of attaching keys to the elasticized fabric
and their challenges
- Test methods for the evaluation of the relative performance
properties of covered elastane yarns for fibers/filaments
- Production of woven fabrics from covered yarns
- Stress-strain and hysteresis creep behavior of elastane
yarns and fabrics
- Protection of fabric edges
- Dyeing, heat setting and finishing processing for covered
elastane yarns
- Adhesive bonding methods for plastic/fabric connection
- Keyboard frame latching
- Subassembly testing and prototyping
