Keyboard Stabilizer Bar Noise Reduction via Buffering Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional keyboard devices generate unpleasant noise due to collisions between metallic stabilizer bar hooks and the base plate during key operation, affecting user experience.
Innovation Solution
Incorporating a buffering element made of soft material between the connecting structure and the hook parts of the stabilizer bars, which absorbs impact and separates the hooks from direct contact with the metallic base plate, reducing noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If metallic stabilizer bars are used to prevent keycap rocking, then structural stability is improved, but collision noise between metallic components increases
Solution Approach 1:
A buffering element made of soft material is introduced as an intermediary between the metallic stabilizer bar hook and the metallic base plate. This mediator prevents direct contact between the two metallic components, eliminating collision noise while preserving the stabilizing function. The buffering element absorbs impact forces and provides a quiet interface between the moving stabilizer bar and the fixed base plate.
Solution Approach 2:
The solution employs a composite material approach by combining metallic components (stabilizer bar and base plate for structural strength) with a soft buffering material (for noise reduction). This composite construction allows the system to simultaneously achieve structural stability from the metallic parts and noise reduction from the soft material interface.
2Stability of the object's composition
If stabilizer bars with hook parts are used to prevent keycap rocking, then key structure stability is improved, but impact collisions between hooks and base plate generate noise
Solution Approach 1:
The buffering element is pre-installed on the base plate at the location where the stabilizer bar hook will contact during key operation. This beforehand cushioning prepares the impact zone with a soft material that absorbs the inevitable collision forces, preventing the generation of impact noise while maintaining the stabilizing function of the hook-and-base plate connection.

AI summary
A keyboard device includes a key structure, a switch circuit board, a base plate and a buffering element. The key structure includes a keycap and a stabilizer bar. The stabilizer bar is connected with the keycap. The base plate includes a connecting structure. The stabilizer bar is penetrated through the connecting structure and connected with the base plate. The buffering element is coupled with the connecting structure. The stabilizer bar and the base plate are made of metallic material. Since the stabilizer bar and the base plate are separated by the buffering element, the keyboard device is capable of reducing noise.
