Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mouse roller modules offer limited flexibility in scrolling modes, requiring users to search for suitable devices that meet their specific needs, leading to reduced working efficiency due to default settings that do not accommodate individual preferences.
Innovation Solution
A mouse roller module equipped with a ring-shaped magnet and an electromagnet, where a sensing unit detects the pole of the ring-shaped magnet, and a control unit adjusts the magnetic force between the magnets to allow users to selectively increase or decrease the rotating speed of the roller, enabling customizable scrolling modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional mechanical hyper-fast scrolling is used based on inertia, then scrolling functionality is provided, but the user cannot adjust the scrolling speed according to personal preferences
Solution Approach 1:
The patent replaces the conventional mechanical inertia-based hyper-fast scrolling mechanism with an electromagnetic system. An electromagnet interacts with a ring-shaped magnet on the roller through magnetic attraction and repulsion forces, enabling electronic control of scrolling speed and mode without relying on mechanical inertia. This substitution allows for programmable and adjustable scrolling behavior.
Solution Approach 2:
The patent changes the physical state and interaction parameters between the electromagnet and ring-shaped magnet by controlling the polarity alignment (like poles or opposite poles). This enables dynamic adjustment of magnetic force strength, which directly controls the roller's rotating speed and scrolling behavior, providing multiple adjustable scrolling modes.
2Productivity
If default scrolling modes are provided, then basic scrolling functionality is achieved, but users must search for suitable devices that meet their specific needs
Solution Approach 1:
The patent makes the scrolling system dynamic and adjustable rather than fixed. Users can real-time adjust scrolling speed and modes according to their preferences without needing to search for different devices. The system adapts to user needs through electronic control of the electromagnet's magnetic field, providing customization within the same device.
3Adaptability or versatility
If the electromagnet and ring-shaped magnet are configured to generate adjustable magnetic force, then scrolling speed can be customized, but device complexity increases
Solution Approach 1:
The electromagnet serves multiple functions: it can generate attractive force, repulsive force, and can be controlled to provide different strength levels. This single component replaces what would otherwise require multiple mechanical components for speed control, reducing overall system complexity while maintaining versatility.

AI summary
A mouse roller module includes a roller, a sensing unit, an electromagnet and a control unit. The roller includes a ring-shaped magnet and a rotating shaft. The rotating shaft is extended along a first direction. When an external force is exerted on the roller, the ring-shaped magnet is rotated about the rotating shaft. The sensing unit is located near the roller to sense a pole of the ring-shaped magnet. The roller is arranged between the electromagnet and the sensing unit. The electromagnet and the ring-shaped magnet interact with each other to generate a magnetic force. The control unit is electrically connected with the sensing unit and the electromagnet. The control unit controls the electromagnet and the ring-shaped magnet of the roller to generate the magnetic force according to a result of sensing the pole of the ring-shaped magnet by the sensing unit.
