Adjustable Mouse Housing for Left and Right Hand Ergonomics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ergonomic mice are typically designed for either right- or left-handed users, making it difficult for individuals with different dominant hands to use them comfortably, as bilaterally symmetrical designs fail to provide optimal grip and adaptability.
Innovation Solution
A mouse design featuring a movable housing module and fixing assembly that allows the device to switch between left- and right-side positions, accommodating different hand shapes, thereby enabling users to adjust the mouse to suit their dominant hand.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mouse is designed with a fixed ergonomic shape for right-handed users, then the grip comfort for right-handed users is improved, but the adaptability for left-handed users deteriorates
Solution Approach 1:
The mouse housing incorporates movable components that allow the user to adjust the shape and orientation of the mouse body. The housing can be reconfigured between different positions (e.g., right-handed and left-handed configurations) by moving adjustable components, enabling the same mouse to adapt to different user preferences and dominant hands while maintaining ergonomic comfort for each configuration.
2Adaptability or versatility
If a mouse is designed with a bilaterally symmetrical shape to accommodate both left and right-handed users, then the adaptability for different dominant hands is improved, but the grip feeling for individual users deteriorates
Solution Approach 1:
Instead of using a fixed symmetrical design, the mouse employs adjustable housing components that can be reconfigured by the user. This allows the mouse to transition from a generic symmetrical form to a customized asymmetric shape that fits the user's specific hand morphology and dominant hand preference, thereby achieving both adaptability and optimal grip feeling.
Solution Approach 2:
The mouse design allows different parts of the housing to have different properties or configurations. Specifically, the housing includes adjustable components that can be positioned differently based on user needs, creating localized variations in shape and ergonomics while maintaining overall functionality. This enables optimization of the grip area for each user's specific requirements.
3Ease of operation
If manufacturers produce separate mouse models for right-handed and left-handed users, then the ergonomic comfort for each hand orientation is improved, but the production cost and complexity increase
Solution Approach 1:
The mouse design incorporates universal adjustability features that allow a single mouse model to serve multiple functions for different user types. The housing can be reconfigured between right-handed and left-handed configurations, eliminating the need for manufacturers to produce separate dedicated models for each hand orientation. This reduces production complexity and inventory requirements while maintaining ergonomic comfort for all users.

AI summary
A mouse and a back cover of a holding device adjustable for left and right hand shapes are provided. The mouse includes: a key module that includes at least one button unit, a circuit base that includes a bottom casing and a control module, and a housing module fixed to the circuit base. The control module is electrically connected to the at least one button unit. The housing module includes a movable housing and a fixing assembly. The movable housing is operable to move left or right relative to the circuit base and switch between left-side and right-side positions. The fixing assembly is operable to fix the movable housing, which is located at the left-side or the right-side position, with the circuit base. When the movable housing is located at the left-side or the right-side position, the mouse is adapted for a right-handed or a left-handed user, respectively.
