Multi-Pivot Key Structure for Stable Low-Noise Keystrokes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Keyboards generate noise due to collisions between the balance bar and the bottom plate when the keycap moves up and down, which needs to be reduced for improved user experience.
Innovation Solution
A key structure design featuring a keycap with multiple pivoting portions connected to a first bracket and a second bracket, allowing the keycap to move steadily relative to the bottom plate without the need for additional balance bars, thereby reducing noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a balance bar is disposed in a longer key structure to improve structural strength and stability, then the keycap can move steadily, but noise is generated due to collision between the balance bar and the bottom plate
Solution Approach 1:
The invention removes the balance bar from the key structure, extracting the noise-generating component while maintaining keycap stability through alternative pivot connections between the keycap and bottom plate
Solution Approach 2:
The key structure is divided into multiple pivot connection points distributed across the keycap and bottom plate, replacing the single balance bar support with distributed pivot portions that provide stability without collision noise
2Stability of the object's composition
If multiple first pivoting portions are disposed on the keycap and connected to the first bracket, then the keycap can move up and down steadily, but the structure becomes more complex
Solution Approach 1:
The invention integrates the pivot connections directly into the keycap and bottom plate structures, merging the support function into the existing components rather than adding separate balance bar mechanisms
Solution Approach 2:
The key structure employs multiple dynamic pivot connections that allow controlled movement at each contact point, enabling smooth keycap motion while distributing mechanical stress across multiple locations
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 design effectively eliminates or reduces noise caused by balance bar collisions, enabling the keycap to move smoothly up and down, enhancing the key structure's stability and user experience.
Implementation Method 1
The elastic element is disposed under the keycap
Implementation Method 2
the first bracket is pivotally connected to the first pivoting portions. The second bracket is disposed between the keycap and the bottom plate, and the second bracket is rotatably pivoted to the first bracket
