Luminous Scroll Module Light Leakage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing luminous scroll modules for mice face issues such as luminance decrease, luminance change, light leakage, and abrasion of the middle button switch module due to improper placement of the luminous module, which affects the tilted design of the control end and causes noise or damage.
Innovation Solution
A luminous scroll module design featuring a groove with a clamping element, an inner wheel, and a luminous module where the circuit board partially passes through an opening to position the luminous unit in an accommodating space, allowing light to emit through a light source opening, with a circular and annular shading element to prevent light leakage and a pressing element to avoid abrasion, ensuring the luminous module does not interfere with the tilted design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the luminous module is disposed above the rotating shaft, then the luminous module can be positioned close to the scroll, but the tilted design of the top cover is affected and the luminous unit is excessively close to the groove inner circumference causing luminance change or light leakage
Solution Approach 1:
The patent positions the luminous module in a different spatial dimension - specifically below the rotating shaft rather than above it, and uses the inner wheel's accommodating space to house the luminous unit. This dimensional repositioning resolves the conflict between achieving adequate luminance and maintaining the top cover's tilted design by eliminating the interference with the groove inner circumference.
2Shape
If the luminous module is disposed below the rotating shaft, then the tilted design is preserved, but the rotating shaft blocks light beams resulting in luminance decrease
Solution Approach 1:
The patent introduces the inner wheel as an intermediary structure with an accommodating space that houses the luminous unit. The inner wheel's outer ring wall with its light source opening serves as a mediator to transmit light from the luminous unit to the scroll without being blocked by the rotating shaft, thus preserving both the tilted design and adequate luminance.
3Ease of operation
If the rotating shaft is present in the groove, then the scroll can rotate, but the rotating shaft abuts against the middle button switch module causing abrasion or damage
Solution Approach 1:
The patent extracts the clamping function from the rotating shaft by introducing a separate clamping element that is pivotally connected to the inner wheel's second side plate. This separation allows the rotating shaft to rotate freely without abutting against the middle button switch module, while the clamping element provides the necessary clamping force, thus improving the reliability of the middle button switch module while maintaining ease of operation.
