Ergonomic Mouse Frame with Hollow Portions for Weight Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mouse devices cause discomfort due to prolonged use, as they do not effectively alleviate the burden on the wrist, despite some attempts to adjust the center of gravity with weight blocks.
Innovation Solution
A mouse device design featuring a frame with hollow portions that penetrates the device, allowing for weight reduction and ergonomic support, with detachable weight members and a battery compartment to adjust the center of gravity and improve user comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If weight blocks are added to adjust the center of gravity, then the operating feel can be customized, but the overall weight of the mouse device increases
Solution Approach 1:
The patent removes material from the mouse body to create hollow portions, extracting unnecessary mass while maintaining structural integrity. This approach reduces the overall weight of the mouse device without requiring additional weight blocks, thereby solving the contradiction between weight reduction and center of gravity adjustability.
Solution Approach 2:
The patent changes the physical structure of the mouse by creating hollow portions with specific volumes and positions, thereby altering the mass distribution and center of gravity parameters. This allows for weight reduction while maintaining or optimizing the center of gravity position for ergonomic performance.
2Strength
If the mouse device structure is made solid and compact, then the structural strength is improved, but the weight of the device increases
Solution Approach 1:
The patent introduces hollow portions within the mouse body structure, creating a porous or cavity-containing design. This reduces the overall density and weight of the mouse while maintaining sufficient structural strength through strategic placement and sizing of the hollow portions, preventing the structure from becoming overly dense or solid.
Solution Approach 2:
The patent divides the mouse body into multiple sections with hollow portions strategically positioned within them. This segmentation allows the structure to maintain strength in critical areas while reducing weight in non-critical areas, resolving the contradiction between structural integrity and weight reduction.
3Weight of moving object
If the hollow portion is positioned in the front operation body, then the weight reduction is maximized, but the ergonomic support for the palm is reduced
Solution Approach 1:
The patent applies different structural qualities to different regions of the mouse. The front operation body contains hollow portions for weight reduction, while the rear support body maintains a more solid construction to provide ergonomic support for the palm. This local differentiation resolves the contradiction between weight reduction and ergonomic support.
Solution Approach 2:
The patent creates an asymmetric distribution of hollow portions, concentrating them in the front operation body while maintaining structural integrity in the rear support body. This asymmetric design allows optimal weight reduction in the operational area while preserving ergonomic support functions in the support area.

AI summary
A mouse device includes an operation body and a frame. The frame is engaged with the operation body and has a hollow portion. The hollow portion penetrates the mouse device from a side of the mouse device to another side of the mouse device. The frame includes two finger resting portions and a palm resting portion. The two finger resting portions are respectively located at opposite sides of the operation body. The palm resting portion is connected between the two finger resting portions. The hollow portion is formed among the two finger resting portions and the palm resting portion. In a forward-backward axial direction of the mouse device, the frame is located behind the operation body.
