Rolling Mechanism Elastic Counterforce for Mouse Noise and Position Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mouse devices often generate noise and fail to maintain the roller at a middle position due to fit clearance issues between the encoding element and the supporting element, leading to user experience issues.
Innovation Solution
A rolling mechanism with an elastic element, such as a torsion spring, is integrated between the roller module and the encoding element, providing a counterforce to reduce noise and maintain the roller's position through elastic recovery, ensuring smooth operation and reduced shaking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a roller is used in the mouse device, then the user can operate the mouse by rolling, but noise is generated due to fit clearance between the encoding element and supporting element
Solution Approach 1:
An elastic element is introduced as an intermediary component between the roller module and the encoding element. This elastic element fills the fit clearance gap and acts as a mediator that eliminates direct contact and impact between the roller and encoding element, thereby reducing noise while preserving the rolling operation function
Solution Approach 2:
The elastic element provides beforehand cushioning by being pre-installed in the fit clearance space. When the roller operates, the elastic element is already in position to absorb and cushion the impact before it reaches the encoding element, preventing noise generation from the outset
2Ease of operation
If the roller is made movable on the base, then the roller can be pressed and rolled, but the roller shakes and cannot maintain at the middle position
Solution Approach 1:
The elastic element functions as a counterforce mechanism that opposes the roller's displacement from the middle position. When the roller moves away from center, the elastic element generates a restoring force that pushes it back, effectively counterbalancing the instability and maintaining positional stability during operation
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 elastic element effectively reduces noise and stabilizes the roller at the middle position, enhancing user experience by minimizing operational noise and improving the roller's positioning accuracy.
Implementation Method 1
the elastic element is propped against the roller module... providing a counterforce to reduce noise and maintain the roller's position through elastic recovery
