Mouse Scroll Wheel Speed-Adaptive Control Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mouse devices require continuous and laborious rotation of the scroll wheel to navigate large windows, making them less user-friendly when switching between numerous pages.
Innovation Solution
A mouse device with a microprocessor that generates control commands based on the rotating speed of the scroll wheel, issuing a first command for quick rotations and a second command for slower rotations, allowing for adjustable scrolling speeds.

Engineering Contradiction Analysis
1Ease of operation
If the scroll wheel is rotated continuously to switch between many pages, then the window content can be browsed, but the operation becomes laborious and time-consuming
Solution Approach 1:
The patent applies dynamics by making the scrolling speed variable rather than fixed. The scrolling speed dynamically changes based on the rotating speed of the scroll wheel - when the user rotates the wheel faster, the scrolling speed increases proportionally. This dynamic adjustment allows users to quickly navigate through large amounts of content by simply rotating the wheel faster, without requiring continuous slow rotations for each page, thereby reducing both operational effort and time consumption.
2Productivity
If the scroll wheel rotation amount is increased to browse more pages, then more content can be viewed, but the device complexity increases
Solution Approach 1:
The patent applies parameter changes by modifying the relationship between scroll wheel rotation and scrolling speed. Instead of a fixed one-to-one mapping, the system changes the parameter of scrolling speed based on the rotation speed parameter. The microprocessor monitors how fast the scroll wheel is rotated and adjusts the scrolling speed accordingly, allowing users to achieve higher productivity by rotating faster without adding complex mechanical components like variable gear ratios or multiple scroll wheels.
Data Source
AI summary
A mouse device includes a casing, a scroll wheel, a circuit board, an encoder and a microprocessor. The scroll wheel is partially exposed outside the casing. The circuit board is disposed within the casing. The encoder is disposed within the casing. The encoder issues an encoded signal to the circuit board in response to a rotation of the scroll wheel. The microprocessor is electrically connected with the circuit board, and acquires a rotating time period corresponding to one-unit rotation amount of the scroll wheel. If the rotating time period is shorter than a predetermined time period, the microprocessor generates a first control command. If the rotating time period is longer than or equal to the predetermined time, the microprocessor generates a second control command.
