Elastomeric Hinge Assembly for Foldable Computing Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional computing devices with fixed footprints are suboptimal for use in limited spaces and can be cumbersome when used with one hand, as they often have uncomfortable designs that may pick up dirt or germs and lack ergonomic flexibility.
Innovation Solution
A device with a hinge assembly that includes an elastomeric element and a latch mechanism, allowing for adjustable orientations and a foldable design that reduces the footprint, provides a grip, and protects the keyboard from contact with surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed footprint design is used, then structural simplicity is maintained, but ergonomic flexibility and adaptability to limited spaces are reduced
Solution Approach 1:
The hinge assembly enables the device to transition between fixed and folded states, allowing dynamic adjustment of the device footprint and orientation while maintaining structural integrity through the elastomeric element and latch mechanism
Solution Approach 2:
The device is divided into separable portions connected by the hinge assembly, allowing independent positioning of each section to achieve various ergonomic configurations while keeping the overall structure manageable
2Area of moving object
If a foldable design with hinge assembly is implemented, then footprint reduction and ergonomic flexibility are improved, but device complexity increases
Solution Approach 1:
When folded, one portion of the device nests within or alongside another portion, minimizing the overall footprint while the hinge assembly manages the transition between expanded and compact configurations
Solution Approach 2:
The elastomeric element provides automatic return force to the hinge assembly, enabling the device to self-return to a neutral position without requiring additional motors or actuators, thus reducing complexity while achieving foldability
3Ease of operation
If conventional fixed design is used, then manufacturing simplicity is maintained, but ease of operation for one-handed use deteriorates
Solution Approach 1:
The hinge assembly allows the device to be adjusted to comfortable viewing and typing angles for one-handed operation, transforming a static difficult-to-use device into a dynamically adjustable ergonomic tool
Solution Approach 2:
The device geometry and orientation parameters can be changed through the hinge mechanism to optimize for one-handed use, allowing users to adjust angles and positions without requiring complex control systems
4Object-affected harmful factors
If keyboard is exposed in fixed design, then accessibility is maintained, but susceptibility to dirt and germs increases
Solution Approach 1:
The foldable design allows the keyboard portion to be dynamically positioned - either exposed for accessibility or folded away for protection - enabling users to adapt the device configuration based on environmental conditions and usage needs

AI summary
An apparatus can include a processor; memory accessible by the processor; a first housing where the processor and the memory are disposed in the first housing; a second housing; a hinge assembly that operatively couples the first housing to the second housing where the hinge assembly includes an elastomeric element that includes a native state and a bent tension and compression state; and a latch mechanism that latches a side of the first housing to a side of the second housing in the bent tension and compression state of the elastomeric element.
