Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mouse devices have a fixed armrest size, which fails to accommodate users with varying palm sizes, leading to discomfort during use.
Innovation Solution
A mouse device with an armrest height adjustment function, featuring a pivotally coupled armrest and an armrest lifting module comprising a support element, height-adjusting elastic element, coupling elements, and a push mechanism, allowing users to adjust the armrest height to suit their palm size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the mouse device has a fixed volume, then the device structure is simple and easy to manufacture, but the device cannot accommodate users with different palm sizes
Solution Approach 1:
The armrest is designed to be height-adjustable rather than fixed, allowing users to customize the armrest height according to their palm size. The armrest lifting module includes a support element, elastic element, coupling elements, and push element that work together to enable smooth height adjustment while maintaining structural integrity
Solution Approach 2:
The armrest lifting module is divided into multiple functional components: support element for structural support, elastic element for providing lifting force, coupling elements for connecting parts, and push element for actuation. This segmentation allows each component to be optimized independently while working together to achieve the overall adjustment function
2Ease of operation
If the armrest height is adjustable, then user comfort is improved, but the device complexity increases
Solution Approach 1:
The elastic element automatically provides the lifting force needed to raise the armrest when the push element is actuated. The system uses the user's pushing action combined with the elastic element's stored energy to achieve height adjustment, reducing the need for complex motors or actuators
Solution Approach 2:
The coupling elements serve as intermediaries that transmit and coordinate the mechanical forces between the push element, support element, and armrest. The coupling rack and coupling齿条 engage to transfer motion smoothly, simplifying the overall mechanism by providing clear mechanical advantage

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances user comfort by allowing customizable armrest height adjustment, extending the device's structural stability and use life by securely supporting the user's palm and accommodating different palm sizes.
Implementation Method 1
The height-adjusting elastic element is sheathed around the support element. The height-adjusting elastic element is arranged between the mouse body and the armrest

AI summary
A mouse device includes a mouse body, an armrest and an armrest lifting module. The armrest is pivotally coupled to the mouse body. The armrest lifting module includes a support element, a height-adjusting elastic element, a first coupling element, a second coupling element, a push element and a slid switch. The two ends of the support element include a connection segment and a free segment, respectively. The connection segment is connected with the armrest. The free segment is penetrated through the mouse body and disposed within the mouse body. The height-adjusting elastic element is sheathed around the support element. The first coupling element is connected with the free segment, and includes a coupling rack. The push element is installed within the mouse body. The push element is movable to push the second coupling element. The slide switch is connected with the push element.
