Glass Scroll Wheel Inertia Module for Mouse
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mice have insufficient rotational inertia due to lightweight plastic scroll wheels, making them inconvenient for prolonged scrolling operations, such as dragging content on a display screen.
Innovation Solution
A mouse with an inertia scroll wheel module featuring a non-metallic scroll wheel, typically made of glass or ceramic, and an antiskid outer ring, which increases the scroll wheel's weight and rotational inertia, along with an encoder and ratchet mechanism to enhance usability and reduce noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the scroll wheel is made of plastic material, then the manufacturing cost is low and ease of manufacture is improved, but the rotational inertia is insufficient and scrolling time is short
Solution Approach 1:
The scroll wheel is made of glass material instead of plastic material. Glass material has higher density and weight, which increases the rotational inertia of the scroll wheel. This allows the scroll wheel to maintain rotation for a longer time without continuous user input, resolving the contradiction between ease of manufacture and scrolling time by accepting slightly more complex manufacturing processes for glass while achieving significantly improved scrolling duration.
2Duration of action of moving object
If the scroll wheel is made of glass or ceramic material, then the rotational inertia is increased and scrolling time is prolonged, but the manufacturing complexity and cost increase
Solution Approach 1:
The patent changes the material parameter of the scroll wheel from plastic to glass or ceramic. This parameter change increases the density and weight of the scroll wheel, thereby increasing rotational inertia and scrolling time. The solution accepts increased manufacturing complexity as a trade-off for achieving the desired improvement in scrolling duration and user convenience.
3Ease of operation
If the scroll wheel is lighter, then the ease of operation is improved for quick scrolling, but the rotational inertia is insufficient requiring continual scrolling input
Solution Approach 1:
The scroll wheel uses glass material which provides optimal balance between weight and inertia. The increased weight improves rotational inertia to maintain scrolling motion longer, reducing the need for continual user input. This resolves the contradiction by achieving both ease of operation (through smoother, longer-lasting rotation) and productivity (by reducing repeated scrolling actions needed to navigate content).
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 increased rotational inertia prolongs scrolling time, improves user convenience, and extends the service life of the scroll wheel module by reducing decentering and noise, while the transparent materials provide an improved optical effect.
Implementation Method 1
the scroll wheel is relatively light. Therefore, rotational inertia of the scroll wheel of the conventional mouse is relatively insufficient. weight of the scroll wheel is increased, so as to increase rotational inertia of the scroll wheel, thereby prolonging scrolling time of the scroll wheel
