Adjustable Palm Rest Mouse with Rotating Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional computer mice have a universal symmetrical design that fails to accommodate the unique shape and size of individual hands, leading to uncomfortable holding postures and potential hand and wrist injuries.
Innovation Solution
A computer mouse with an adjustable palm rest that allows for varying inclined angles, featuring a rotatable connecting base and supporting casing with a positioner chain and orientation module, enabling users to customize the palm rest to their specific needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a universal symmetrical design is used for the computer mouse, then the device can be held in either the right hand or left hand, but the user is forced to use a fixed configuration in an uncomfortable holding posture
Solution Approach 1:
The patent applies the dynamics principle by making the palm rest adjustable rather than fixed. The supporting casing can rotate relative to the connecting base along a second axis, allowing the palm rest angle to be dynamically changed between a first angle and a second angle. This enables the mouse to adapt to different user preferences and hand positions, resolving the contradiction between universal design and holding comfort.
Solution Approach 2:
The patent implements parameter changes by varying the inclined angle of the palm rest. The positioner chain includes multiple positioning dimples that correspond to different angles, allowing the user to select and lock the palm rest at different inclinations. This parameter adjustment enables the same mouse to accommodate both right-handed and left-handed users with optimal comfort, addressing the contradiction between versatility and ease of operation.
2Device complexity
If a fixed configuration computer mouse is used, then the structure is simple, but the user may injure the hand and wrist due to uncomfortable holding posture
Solution Approach 1:
The patent introduces dynamic adjustability to the mouse structure through the rotatable supporting casing and positioner chain mechanism. This allows the palm rest angle to be changed, enabling users to find a comfortable holding posture that prevents hand and wrist injuries. The added complexity is minimal and directly addresses the harmful factor of injury risk.
3Adaptability or versatility
If an adjustable palm rest with multiple inclined positions is added, then both right-handed and left-handed users can comfortably use the mouse, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the palm rest adjustment mechanism into distinct functional components: the supporting casing that rotates, the connecting base that provides the rotation axis, the positioner chain with multiple positioning dimples, and the orientation module that locks the position. This segmentation allows for a manageable level of complexity while achieving the desired adjustability for both right-handed and left-handed users.
Solution Approach 2:
The patent uses dynamics to create an adjustable palm rest system where the supporting casing can rotate to different angles and be locked into position. This dynamic capability provides versatility for different users without requiring multiple separate mice, balancing the trade-off between adaptability and device complexity.

AI summary
A computer mouse with an adjustable palm rest includes a main housing defined with a longitudinal direction and a traverse direction and has a carriage. A connecting base is rotatably connected to the carriage along a first axis. A supporting casing has a front wall and a rear wall. A palm-resting cover is fixed to the supporting casing. The front wall is closed to the connecting base. The supporting casing is rotatably connected to the connecting base along a second axis. The supporting casing can be arranged at different oblique angles related to the connecting base. A positioner chain is formed on a surface of the connecting base or the supporting casing and has a plurality of positioning dimples. A positioning assembly abuts against one of the dimples and retains the supporting casing at one of the oblique angles related to the connecting base.
