Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing mice with fixed balancing weights at the top create an imbalance, making the top feel heavy and the bottom light, leading to difficulty in handling.

Innovation Solution

A mouse design with balancing weight lumps placed at the bottom of the case, distributed in notches, providing adjustable weight distribution for improved stability and ease of use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the balancing weight element is fixed at the top of the mouse case, then the structure is simple and easy to manufacture, but the weight distribution becomes unbalanced making the top feel heavy and the bottom feel light

Engineering Contradiction:

Improveease of manufactureVSAvoidease of operation

Core Design Contradiction:

Ease of manufactureVSEase of operation

Solution Approach 1:

The patent inverts the conventional placement of balancing weights by moving them from the top of the case to the bottom of the case. This inversion corrects the weight distribution imbalance, making the bottom of the mouse feel heavier and the top feel lighter, thereby improving handling characteristics while maintaining manufacturing simplicity

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent applies local quality by creating specific weight distribution characteristics at different locations of the mouse case. By placing balancing weight elements specifically at the bottom of the case rather than uniformly distributing weight, the patent achieves localized weight adjustment to improve handling while keeping the overall structure simple

Inventive Principle:

Principle #3Local quality

2Device complexity

If the balancing weight element is fixed at the top of the mouse case, then the structure is simple, but the weight distribution creates difficulty in handling the mouse

Engineering Contradiction:

Solution Approach 1:

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent segments the balancing weight function by using multiple separate balancing weight elements that can be independently placed in the bottom of the case. This segmentation allows for flexible weight distribution adjustment while keeping each individual component simple and the overall structure manageable

Inventive Principle:

Principle #1Segmentation
