Keyboard Stabilizer Bar Hook Support Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional keyboard devices experience an 'empty travel distance' issue when pressing the corner of a keycap due to gaps between the stabilizer bar hooks and locking holes, which affects the keycap's stability and tactile feedback.
Innovation Solution
The keyboard device incorporates a supporting structure between the stabilizer bar hooks and the base plate locking holes, ensuring the hooks are continuously contacted with the inner walls, preventing gaps and enhancing keycap support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the stabilizer bar hooks are simply penetrated through the locking holes without additional support, then the device complexity is reduced, but gaps form between the hooks and inner walls causing empty travel distance
Solution Approach 1:
A supporting structure is introduced as an intermediary component between the stabilizer bar hooks and the base plate locking holes. This supporting structure fills the gap between the hook and inner wall, eliminating empty travel distance while maintaining a modular design that doesn't significantly complicate the overall device structure.
Solution Approach 2:
The connection between the stabilizer bar and base plate is segmented into multiple functional parts: the hook portion that penetrates the locking hole, and the supported portion that contacts the inner wall through the supporting structure. This segmentation allows each part to perform its specific function optimally - the hook provides penetration while the supporting structure ensures continuous contact.
2Reliability
If the hook parts are made larger to eliminate gaps, then the contact with inner walls improves, but the manufacturing precision requirements increase
Solution Approach 1:
Rather than enlarging the hook parts which would increase manufacturing precision requirements, a supporting structure is introduced as a mediator. This supporting structure is specifically designed to fill the gap between the hook and inner wall, achieving continuous contact without requiring high-precision manufacturing of the hook components themselves.
3Ease of operation
If the supporting structure is added to ensure continuous contact, then tactile feedback improves, but the device complexity increases
Solution Approach 1:
The supporting structure is integrated with the stabilizer bar assembly, merging the support function into the existing structure. This integration ensures that the supporting structure becomes part of the keycap stabilization mechanism, providing tactile feedback during corner pressing without requiring separate independent components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design effectively addresses the empty travel distance problem by ensuring the stabilizer bar supports the keycap consistently, improving keycap stability and tactile feedback even when pressing the corner of the keycap.
Implementation Method 1
the keycap 101 is moved upwardly relative to the base plate 11 in response to an elastic force of the elastic element 103
Implementation Method 2
the scissors-type connecting element 102 comprises a first frame 1021 and a second frame 1022. The second frame 1022 is pivotally coupled to the first frame 1021. Consequently, the first frame 1021 and the second frame 1022 can be swung relative to each other
Implementation Method 3
The transverse bar part 1041 of the stabilizer bar 104 is pivotally coupled to the keycap 101 of the key structure 10′. The two hook parts 1042 of each stabilizer bar 104 are penetrated through the corresponding first locking hole 1111 of the first coupling part 111 and the corresponding second locking hole 1121 of the second coupling part 112
