Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional large-sized keyboard key structures with stabilizer bars generate noise due to friction or impact between the stabilizer bar and hooks, affecting user experience.
Innovation Solution
A key structure design featuring a supporting frame, keycap, stabilizer bar, and flexible hooks made of elastic material, where the flexible hooks clamp the branch bar parts of the stabilizer bar, reducing noise and providing a buffering effect during keycap movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a stabilizer bar is connected with hooks on the keycap to increase structural strength, then the keycap stability is improved, but friction or impact between the stabilizer bar and hooks generates noise
Solution Approach 1:
The patent introduces a buffer element as an intermediary component between the stabilizer bar and the keycap hooks. This buffer element absorbs the impact and friction interactions, preventing direct contact between the stabilizer bar and hooks, thereby eliminating noise generation while maintaining keycap stability through the mediating buffer component.
Solution Approach 2:
The patent changes the physical parameters of the connection interface by introducing a buffer element with specific material properties (elasticity, damping characteristics). This parameter change transforms the rigid connection into a compliant connection that reduces friction and impact forces, thereby reducing noise while preserving the stabilizing function.
2Strength
If rigid hooks are used to connect the stabilizer bar to the keycap, then the connection strength is improved, but friction and impact generate unpleasant noise
Solution Approach 1:
The patent replaces rigid hooks with flexible buffer elements that have elastic properties. These flexible components can deform under load, absorbing impact energies and reducing friction during keycap actuation. The flexibility maintains connection strength through elastic recovery while eliminating the rigid contact that generates noise.
Solution Approach 2:
The buffer element is pre-installed between the stabilizer bar and keycap hooks to provide beforehand cushioning. This pre-positioned cushioning element absorbs potential impact and friction forces before they can generate noise, protecting the connection interface from harmful interactions while maintaining structural integrity.
