Computer Mouse Friction Zoning for Pen-Like Movement Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional computer mice lack precision in movements required for tasks such as electronic signature, drawing, and gaming, despite ergonomic improvements, and existing mouse pads do not provide the level of precision that humans can achieve with a simple pen.
Innovation Solution
A computer mouse with a resistance point on its bottom surface, activated by a palm button or removable tip, provides precise movement by incorporating a base with cushion members and a tip that extends beyond the cushion members to create resistance, allowing for precise navigation without affecting pointer position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional mouse design is used with smooth sliding surface, then ease of operation is improved, but measurement precision deteriorates
Solution Approach 1:
The mouse bottom surface is divided into two distinct zones: a smooth sliding area for ease of movement and a resistance point area for precision control. This local differentiation allows the mouse to provide both easy sliding operation and precise movement control simultaneously, resolving the contradiction between ease of operation and measurement precision.
Solution Approach 2:
The bottom surface of the mouse is segmented into functional zones with different friction characteristics. The resistance point creates a localized high-friction zone separated from the low-friction sliding zones, enabling independent control of sliding ease and movement precision through spatial segmentation of friction properties.
2Measurement precision
If resistance point is added to mouse bottom surface, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The resistance point is implemented as a simple, replaceable element rather than a complex mechanical system. It can be a small adhesive patch, a removable cap, or a simple friction element that can be easily attached or replaced without disassembling the mouse, thereby adding precision functionality while minimizing structural complexity.
Solution Approach 2:
The resistance point acts as an intermediary element between the mouse and the surface, providing the necessary friction control without requiring internal mechanical complexity. This simple intermediary component mediates the interaction between the mouse and surface to achieve precise movement control.
