Adjustable Scroll Wheel Mechanism for Ergonomic Mouse Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mouse devices have fixed scroll wheels, leading to finger fatigue and discomfort due to the inability to change scrolling direction, causing prolonged use issues.
Innovation Solution
A mouse device design featuring a scroll wheel assembly with a rotary base and transmission mechanism that adjusts the offset angle of the scroll wheel component, allowing for changeable scrolling directions by rotating around a second axis relative to a securing base.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the scroll wheel is secured in a fixed axis, then the structure is simple and stable, but the scrolling direction cannot be adjusted causing finger fatigue
Solution Approach 1:
The scroll wheel assembly is transformed from a fixed structure to a dynamic adjustable structure. The rotary base enables the scroll wheel component to rotate around a second axis, changing the scrolling direction from fixed to adjustable. This allows users to switch between different scrolling directions (e.g., upward, downward, leftward, rightward) to alleviate finger fatigue during prolonged use.
Solution Approach 2:
The scroll wheel assembly is divided into multiple independent components: a securing base, a rotary base, and a scroll wheel component. This segmentation allows the scroll wheel component to be independently rotated relative to the securing base through the rotary base, enabling direction adjustment while maintaining structural stability of the base components.
2Adaptability or versatility
If the scroll wheel assembly structure is simplified, then manufacturing is easier, but the ability to adjust scrolling direction is lost
Solution Approach 1:
The assembly incorporates a rotary base that enables dynamic adjustment of the scroll wheel component's orientation. This mechanical rotation mechanism allows the scroll wheel to be repositioned to different angles, providing versatility in scrolling directions while maintaining a relatively simple manufacturing process based on standard rotational joints.
Solution Approach 2:
By segmenting the assembly into a securing base, rotary base, and scroll wheel component, each part can be manufactured independently using standard processes. The rotary base acts as a connector that simplifies the overall assembly process while enabling the complex function of direction adjustment.
3Ease of operation
If a fixed scroll wheel structure is used, then the device is stable and reliable, but user comfort during prolonged use deteriorates
Solution Approach 1:
The scroll wheel assembly incorporates a rotary base that provides stable rotational movement around a second axis. This dynamic structure allows the scroll wheel component to maintain reliable positional relationships with the securing base while enabling users to adjust scrolling directions for improved comfort during prolonged use.
Solution Approach 2:
The segmented structure with secure connections between the securing base, rotary base, and scroll wheel component maintains system reliability. Each component remains stable in its designated position while the rotary base enables controlled rotation, ensuring both stability and user comfort.

AI summary
The present disclosure provides a mouse device comprising a casing and a scroll wheel assembly. The casing comprises an upper casing and a lower casing. The scroll wheel assembly is disposed between the upper casing and the lower casing, which comprises a securing base secured to the lower casing, a rotary base disposed on the securing base, a scroll wheel component movably disposed on the rotary base rotatable around a first axis relative to the rotary base, a measuring component secured to the rotary base, and a transmission mechanism connected to the rotary base, wherein the transmission mechanism transmits external force to the rotating base, such that the rotary base rotates around a second axis relative to the securing base to adjust the offset angle of the scroll wheel component.
