Keyboard Stabilizer Bar Noise Reduction via Soft Fixing 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
The use of soft fixing elements made of polysiloxane or polymerized siloxane (silicone resin) or soft plastic materials, which are integrated with the base plate to prevent direct contact between metallic hooks and the base plate, allowing hooks to move within accommodation spaces and reducing noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If metallic stabilizer bars are used to maintain key structure stability, then structural stability is improved, but noise is generated due to collisions between metallic hooks and the base plate
Solution Approach 1:
A soft fixing element made of silicone resin is introduced as an intermediary between the metallic stabilizer bar hook and the base plate. This soft element absorbs the collision and prevents direct contact between metallic components, thereby eliminating noise while maintaining the stabilizing function.
Solution Approach 2:
The base plate is constructed as a composite structure combining metallic components with a soft fixing element made of silicone resin. This composite design allows the metallic parts to provide structural strength while the soft material prevents noise-generating collisions.
2Object-generated harmful factors
If soft fixing elements are used to reduce noise, then noise is reduced, but the structural strength may be compromised
Solution Approach 1:
The base plate combines metallic components with silicone resin soft fixing elements. The metallic parts maintain structural strength and rigidity, while the soft elements provide noise reduction. This composite approach ensures both strength and noise reduction requirements are met simultaneously.
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
The implementation of soft fixing elements effectively reduces noise by isolating the metallic hooks from the base plate, enhancing the operational smoothness and tactile feel of key structures without generating unwanted click sounds.
Implementation Method 1
The soft fixing element is disposed on the base plate and connected with the hook part... allowing hooks to move within accommodation spaces and reducing noise

AI summary
A keyboard device includes a key structure, a base plate and a soft fixing element. The key structure includes a keycap and a stabilizer bar. The stabilizer bar is connected with the keycap and the soft fixing element. The soft fixing element is disposed on the base plate. The soft fixing element has an accommodation space. The stabilizer bar is inserted into the accommodation space, so that the stabilizer bar is connected with the base plate. After a fixing post of the soft fixing element is penetrated through a fixing hole of the base plate, the fixing post is thermally treated to form the hot melt fixing structure. Consequently, the soft fixing element is firmly fixed on the base plate. Since the metallic stabilizer bar and the metallic base plate are separated by the soft fixing element, the keyboard device is capable of reducing noise.
