Adjustable Scroll Input Device with Variable Interference Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current input devices, such as mice, typically offer only a single sense of segmented movement and lack the ability to adjust this sensation to accommodate different user habits, as the scroll speed is fixed and cannot be customized.
Innovation Solution
An input device design featuring a holder, a first wheel with a segment adjusting structure, a slider, and a pressure part, where the slider's movement relative to the holder adjusts the interference between the pressure part and the segment adjusting structure, allowing users to customize the scroll speed by altering the force required to scroll the wheel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed encoder mechanism is used to generate segmented movement sense, then the device structure is simple, but the scroll speed cannot be adjusted to meet different user habits
Solution Approach 1:
The patent applies the dynamics principle by making the interference degree between the pressure part and segment adjusting structure adjustable rather than fixed. The slider can move relative to the holder to change the position of the pressure part, thereby dynamically adjusting the interference degree with the segment adjusting structure during use, enabling scroll speed customization while maintaining a relatively simple mechanical structure.
2Speed
If the slider moves toward the circle center to increase interference, then the scroll speed decreases, but the force required to scroll the wheel increases
Solution Approach 1:
The patent applies parameter changes by allowing users to adjust the interference degree parameter between the pressure part and segment adjusting structure through slider movement. When the slider moves toward the circle center, the interference degree parameter increases, which decreases scroll speed but increases the force required. This parameter adjustment mechanism enables users to find the optimal balance between scroll speed and scrolling force according to their preferences.

AI summary
The invention provides an input device including a holder, a first wheel, a slider, and a first pressure part. The first wheel is disposed on the holder, and includes a side surface, a circle center, and a segment adjusting structure. The segment adjusting structure is disposed on the side surface in a manner of surrounding the circle center. The slider is disposed on the holder, and is movable relative to the holder to move toward or away from the circle center. The first pressure part includes two first ends. One of the first ends is connected to the slider, and as the slider moves toward or away from the circle center, interference between the other first end and the segment adjusting structure is increased or reduced.
