Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mouse devices lack the ability to adjust scrolling feel, requiring users to purchase new mice for different scrolling preferences, which is costly and limits flexibility and efficiency.
Innovation Solution
A mouse device with a roller module that can switch between stepped motion and hyper-fast scrolling modes using a magnetic conductor, swingable arm, and driving motor, allowing users to select the desired scrolling feel by adjusting the magnetic attraction force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional mouse roller is used, then the device structure is simple, but the scrolling feel cannot be adjusted and flexibility is limited
Solution Approach 1:
The patent applies dynamics by making the magnetic conductor swingable between two positions. In the first position, the magnetic conductor engages with the magnetic element to provide stepped scrolling feedback. In the second position, the magnetic conductor disengages to enable smooth scrolling. This dynamic repositioning allows a single device to provide multiple scrolling modes, resolving the contradiction between adaptability and device complexity.
Solution Approach 2:
The patent changes the physical state and position parameters of the magnetic conductor to achieve different scrolling modes. By altering the position parameter (swinging between first and second positions) and the engagement state parameter (engaged or disengaged from magnetic element), the system provides variable scrolling characteristics without requiring multiple separate devices, thus improving adaptability while maintaining reasonable complexity.
2Adaptability or versatility
If the magnetic conductor is always engaged with the magnetic element, then stepped scrolling feedback is provided, but smooth scrolling is not available
Solution Approach 1:
The magnetic conductor is designed to be swingable rather than fixed, allowing it to dynamically switch between engagement and disengagement states. This dynamic capability enables the system to adapt to different user needs by providing either stepped or smooth scrolling experience, thereby improving both adaptability and ease of operation.
Solution Approach 2:
The system enables periodic switching between different scrolling modes through the swingable magnetic conductor. Users can alternately engage the magnetic conductor to experience stepped scrolling and disengage it for smooth scrolling, providing operational flexibility and variety in scrolling experience without compromising ease of use.
3Adaptability or versatility
If the swingable arm swings from first position to second position, then scrolling mode switching is achieved, but noise is generated during the transition
Solution Approach 1:
The patent applies beforehand cushioning by introducing a damping element that provides cushioning during the position change of the magnetic conductor. The damping element is positioned to absorb shocks and reduce noise when the magnetic conductor swings between the first and second positions, thereby reducing harmful noise while maintaining the mode switching capability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances operating convenience by allowing users to switch between scrolling modes, providing clear tactile feedback and reducing noise during mode changes, thus improving user experience and efficiency.
Implementation Method 1
a magnetic element is arranged between the swinging part and the magnetic conductor. When the swingable arm is swung to a first position, the magnetic element is aligned with the magnetic conductor, and a magnetic attraction force between the magnetic element and the magnetic conductor is generated

AI summary
A mouse device includes a roller module. The roller module includes a base member, a scroll wheel, a magnetic conductor, a swingable arm, a driving motor and an actuating element. The scroll wheel is installed on the base member. The magnetic conductor is located beside the scroll wheel. When the scroll wheel is rotated, the magnetic conductor is correspondingly rotated. The swingable arm is installed on the base member. The swingable arm includes a magnetic element. The swingable arm is swingable relative to the magnetic conductor. When the swingable arm is swung to a first position, the magnetic element is aligned with the magnetic conductor. Consequently, a magnetic attraction force between the magnetic element and the magnetic conductor is generated. When the swingable arm is swung to a second position, the magnetic attraction force between the magnetic element and the magnetic conductor is eliminated.
