Keyboard Stabilizer Structure for Keycap Levelness and Low Friction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stabilizers fail to maintain the ideal height and levelness of keycaps due to structural characteristics, causing inclination and increased frictional resistance during keycap movement.
Innovation Solution
A stabilizer design featuring a connection rod with arms rotating about a core column as a rotation axis, allowing the arms to move in an upward/downward direction and rotate to a height lower than the connection rod body, minimizing inclination and reducing friction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the stabilizer uses a traditional structure with fixed connection rod arms, then the structure is simple, but the keycap inclination cannot be minimized due to structural characteristics and tolerance
Solution Approach 1:
The connection rod arms are designed to rotate about the connection rod body as a rotation axis, transforming the static stabilizer structure into a dynamic one. This rotation capability allows the arms to adapt to external forces and maintain keycap levelness, resolving the contradiction between structural simplicity and manufacturing precision by introducing controlled motion rather than complex adjustment mechanisms
Solution Approach 2:
The stabilizer structure enables itself to automatically adjust and level the keycap through the rotation of connection rod arms about the connection rod body. The internal structure with inclined surfaces allows the arms to rotate to a lower height, creating a self-correcting mechanism that minimizes keycap inclination without requiring external intervention or complex control systems
2Manufacturing precision
If the connection rod arms are fixed in position, then the frictional resistance is low, but the leveling function is insufficient due to keycap inclination
Solution Approach 1:
The connection rod arms rotate dynamically about the connection rod body in response to keycap movement, allowing the stabilizer to adapt to varying forces while maintaining low frictional resistance. The rotation mechanism enables smooth adjustment without the need for high-friction mechanical connections or complex adjustment systems
Solution Approach 2:
The internal structure with inclined surfaces acts as an intermediary between the connection rod arms and the core column. This inclined structure facilitates the rotation of arms to a lower height, enabling the stabilizer to achieve leveling function while minimizing direct frictional contact between components
3Ease of manufacture
If the stabilizer structure is simplified, then the ease of manufacture is improved, but the inclination of keycap caused by structural characteristics remains
Solution Approach 1:
The stabilizer uses a simple rotational mechanism where connection rod arms rotate about the connection rod body, maintaining ease of manufacture while achieving keycap levelness. This dynamic rotation capability allows the simple structure to automatically compensate for inclination without requiring precision manufacturing of complex adjustment mechanisms
Solution Approach 2:
The stabilizer structure enables itself to automatically correct keycap inclination through the rotation of connection rod arms. The internal inclined structure facilitates this self-correction, allowing the simple and easy-to-manufacture design to achieve good leveling function without requiring complex precision manufacturing processes
