Solution Overview
Problem
Conventional gaming mice with optical effects have limitations such as large volume, high manufacturing costs, and inability to meet slimness requirements due to 3D structural surfaces produced by injection molding, and they often only exhibit fixed luminous patterns or slender-strip light effects.
Innovation Solution
A mouse device incorporating an aspheric light guide plate that guides light beams from a light source to produce a surface lighting effect, achieving a slim design and reducing manufacturing costs by using a thin and flat optical element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional injection molding process with 3D structural surfaces is used for optical elements, then optical effects can be achieved, but the volume and thickness increase, failing to meet slimness requirements
Solution Approach 1:
The patent uses a planar optical element with printed or deposited optical patterns instead of traditional 3D injection molded optical elements. The optical effects are achieved by copying optical functions onto a flat surface through printing or deposition techniques, maintaining slimness while achieving desired illumination effects
Solution Approach 2:
The patent replaces the mechanical injection molding process with printing or deposition methods to create optical elements. This substitution allows for planar structures with integrated optical patterns, eliminating the need for thick 3D molded structures while achieving the same optical functionality
2Illumination intensity
If conventional injection molding process is used for optical elements, then optical effects can be achieved, but the manufacturing cost increases
Solution Approach 1:
The patent employs printing or deposition techniques to create optical patterns on planar elements, which are generally more cost-effective than injection molding complex 3D optical structures. This approach reduces tooling costs and allows for easier customization and lower volume production
Solution Approach 2:
The patent changes the manufacturing parameters from high-cost injection molding to lower-cost printing or deposition processes. This parameter change in the manufacturing method reduces overall production costs while maintaining optical functionality through alternative technical approaches
3Ease of manufacture
If conventional optical elements with fixed patterns are used, then manufacturing is simplified, but the aesthetic appeal and visual effects are limited
Solution Approach 1:
The patent enables dynamic and customizable optical patterns through printing or deposition methods, allowing for varied designs and configurations that can be easily modified. This provides greater aesthetic appeal and visual effects compared to fixed injection molded patterns, while maintaining manufacturing simplicity through digital design approaches

AI summary
A mouse device includes a casing, at least one aspheric light guide plate and a light source. The casing includes an upper cover and a base. The upper cover includes at least one lateral surface. The aspheric light guide plate is installed on the lateral surface of the upper cover. Each aspheric light guide plate includes a light input surface and a light output surface. The light input surface and the light output surface are not in parallel with each other. The light output surface is aligned with the corresponding lateral surface of the casing. The light source is installed on the light input surface of at least one aspheric light guide plate. The light source emits light beams. After the light beams are inputted into the aspheric light guide plate through the light input surface, the light beams are outputted from the light output surface.
