Keyboard Stabilizer Bar Noise Reduction via Intermediary Damping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional keyboard devices produce unpleasant noise due to collisions between metallic stabilizer bars and the base plate during key operation, affecting user comfort and requiring noise reduction improvements.
Innovation Solution
The keyboard device incorporates stabilizer bars connected between the keycap and the connecting assembly, which are designed to prevent collisions with the base plate, reducing noise and enhancing user comfort through a more stable key operation mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If stabilizer bars are connected between the keycap and the base plate, then key stability is improved, but collision noise increases
Solution Approach 1:
A damping element is introduced as an intermediary component between the stabilizer bar and the base plate. This damping element absorbs collision energy and reduces noise while maintaining the stabilizing function of the stabilizer bar assembly.
Solution Approach 2:
The stabilizer bar assembly uses composite construction with metallic components for structural stability and polymeric/damping components for noise reduction. This combination allows the system to achieve both key stability and noise reduction simultaneously.
2Stability of the object's composition
If stabilizer bars are connected between the keycap and the base plate, then key stability is improved, but manufacturing complexity increases
Solution Approach 1:
The damping element is integrated directly into the base plate structure, merging two components into one. This reduces the total number of parts and simplifies manufacturing while maintaining the noise reduction and stabilizing functions.
Solution Approach 2:
The base plate is designed to serve multiple functions: it provides structural support, houses the damping element for noise reduction, and integrates mounting features for the stabilizer bars. This multi-functionality reduces overall device complexity.

AI summary
A keyboard device includes a base plate, a membrane circuit board and a key. The key includes a keycap, a connecting assembly, a first stabilizer bar and a second stabilizer bar. The connecting assembly is connected between the keycap and the base plate. The first stabilizer bar and the second stabilizer bar are connected between the keycap and the connecting assembly. While the keycap is moved upwardly or downwardly relative to the base plate, the first stabilizer bar and the second stabilizer bar are swung to stabilize the key. Since the first stabilizer bar and the second stabilizer bar are connected between the keycap and the connecting assembly, the first stabilizer bar and the second stabilizer bar will not readily collide with or knock on the base plate. During the operation, the generated noise is reduced. Consequently, the operating comfort to the user is enhanced.
