Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing scroll module designs for mice face issues where the luminous module's proximity to the rotating shaft either disrupts the tilt design of the mouse's control end or blocks light emission, leading to inconsistent luminance and potential electrostatic discharge damage.
Innovation Solution
A scroll module design featuring a rotating shaft with light penetrability and a luminous module positioned below it, allowing light to pass through and maintain luminance while avoiding interference with the tilt design and electrostatic discharge risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the luminous module is disposed above the rotating shaft, then the tilt design of the upper cover is maintained, but the luminous unit is too close to or in contact with the inner circumference of the groove, causing light leakage and potential electrostatic discharge damage
Solution Approach 1:
The patent repositions the luminous module from above the rotating shaft to below it, changing the vertical spatial arrangement. This dimensional repositioning allows the luminous unit to be farther from the groove's inner circumference while maintaining the tilt design, thereby reducing electrostatic discharge risk and light leakage without compromising the upper cover's geometric integrity
Solution Approach 2:
The patent introduces a light guide as an intermediary component between the luminous unit and the scroll surface. This light guide transmits light from the luminous unit located below the rotating shaft to the scroll, enabling illumination without requiring the luminous unit to be close to the groove, thus preventing electrostatic discharge damage and light leakage while maintaining the tilt design
2Shape
If the luminous module is disposed below the rotating shaft, then the tilt design of the upper cover is not affected, but the rotating shaft blocks the light emitted by the luminous unit, resulting in lower luminance
Solution Approach 1:
The patent introduces a light guide as an intermediary component that transmits light from the luminous unit located below the rotating shaft to the scroll surface. This light guide bypasses the rotating shaft's blocking effect, delivering adequate light to the scroll to maintain luminance while allowing the luminous module to be positioned below the rotating shaft to preserve the tilt design
Solution Approach 2:
The patent replaces direct light emission toward the user with an optical transmission system using a light guide. This substitution allows light to be directed from the luminous unit below the rotating shaft to the scroll without being blocked by the rotating shaft itself, maintaining illumination intensity while preserving the tilt design
3Device complexity
If the luminous unit is placed close to the inner circumference of the groove, then the structure is compact, but electrostatic discharge damage occurs to the luminous unit
Solution Approach 1:
The patent repositions the luminous module from above to below the rotating shaft, changing the vertical spatial arrangement. This dimensional change increases the distance between the luminous unit and the groove's inner circumference, reducing electrostatic discharge risk while maintaining structural compactness through efficient space utilization
Solution Approach 2:
The patent introduces a light guide as an intermediary that transmits light from the luminous unit to the scroll surface. This allows the luminous unit to be positioned farther from the groove (improving electrostatic discharge protection) while the light guide maintains the optical function, achieving both reliability improvement and structural efficiency
