Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computer mouse scroll wheel designs are complex and difficult to assemble, lacking a simplified mechanism that allows for both rotation and lateral movement to effectively translate into scrolling signals for up, down, left, and right navigation within a window.
Innovation Solution
A computer mouse scroll wheel module utilizing a mechanical revolving encoder and a holding part with a swing base and holder, enabling the scroll wheel to rotate and sway laterally, with contact pins and springs to translate movement into electronic signals for scrolling and button-like functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional scroll wheel designs are used with multiple separate components, then the functionality of scrolling in multiple directions is achieved, but the assembly complexity increases and manufacturing becomes difficult
Solution Approach 1:
The patent combines multiple functional components (scroll wheel, encoder, holding part, swing base, contact pins, and springs) into an integrated assembly where the swing base pivots within the holder to enable both rotation and lateral movement functions through a single unified structure, reducing the number of separate assemblies needed
Solution Approach 2:
The scroll wheel serves multiple functions: it can rotate to scroll up/down, sway laterally to scroll left/right, and press down to activate button functionality, all through the same physical component interacting with the encoder and contact pins
2Ease of manufacture
If a simplified scroll wheel design is used, then assembly becomes easier, but the ability to translate movements into accurate electronic signals may be compromised
Solution Approach 1:
The mechanical revolving encoder acts as an intermediary between the physical scroll wheel movements and the electronic signals, accurately translating both rotational and lateral movements into corresponding digital signals without requiring complex mechanical linkages
Solution Approach 2:
The patent replaces complex mechanical signal transmission mechanisms with an electronic encoder system that optically or mechanically detects the position and movement of the scroll wheel, providing precise signal translation with simpler mechanical components
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
The solution provides a simplified and easy-to-assemble mechanism that effectively translates scroll wheel movement into electronic signals for seamless scrolling in multiple directions, enhancing user interaction with improved assembly efficiency.
Implementation Method 1
a mechanical revolving encoder and a holding part, which consists of a swing base and a holder supporting the swing base. With the holding part, the scroll wheel of the revolving part is able to rotate and swing laterally so that the window on the screen can be scrolled up, down, left or right, accordingly

AI summary
A mouse scroll wheel module includes a retention part, a holding part sitting on the retention part to swing from front to back and from left to right, a revolving part installed on the holding part, a mechanical revolving encoder to receive output of encoded electronic signals as the revolving part rotates, and a circuit board for controlling a middle switch and right and left switches, fixed between the retention part and the holding part. The holding part comprises a swing base and a holder that supports the swing base. With the support of the holding part, the scroll wheel of the revolving part is able to rotate and swing laterally, making the currently selected window on the screen to scroll in four directions: up, down, left or right.
