Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mice require significant force to retract and extend, making them inconvenient and strength-consuming, especially when designed to be compact for reduced space occupation.
Innovation Solution
A mouse structure featuring a housing with a sliding apparatus system, including a first sliding element and a second sliding apparatus, where magnets create an invisible force to facilitate easy extension and retraction by minimizing the required pulling force, allowing the second sliding apparatus to slide automatically into the accommodating portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the mouse is designed with a retractable portion to reduce space occupation, then the physical size when not in use is reduced, but significant force is required to retract and extend the retractable portion
Solution Approach 1:
The patent uses a spring mechanism as a counterforce element to offset the resistance during retraction and extension. The spring is pre-compressed or pre-tensioned to provide an opposing force that balances the friction and mechanical resistance in the sliding mechanism, thereby reducing the net force the user must apply.
Solution Approach 2:
The patent employs a dynamic sliding mechanism where the retractable portion can smoothly transition between extended and retracted states. The sliding structure includes guide rails and movable components that adapt to the motion state, reducing friction during movement and enabling easy retraction and extension.
2Stability of the object's composition
If the retractable portion requires application of certain force during the whole process of retracting and pulling, then the structure can maintain stability, but it becomes strength-consuming and inconvenient in use
Solution Approach 1:
The spring mechanism provides a counterbalancing force that reduces the effort needed to operate the retractable portion while maintaining structural stability. The spring is designed to engage and disengage smoothly, ensuring the structure remains stable in both extended and retracted states without requiring excessive user force.
Solution Approach 2:
The sliding mechanism is designed to be dynamically responsive to user input, allowing smooth transitions between states with minimal force. The guide rails and movable components are optimized to reduce friction and provide stable positioning when stationary, while enabling easy movement during operation.

AI summary
A mouse structure includes a housing and first and second sliding apparatuses. The housing has an accommodating portion and an opening The first sliding apparatus includes a base board and a sliding element, the base board being fixedly disposed in the accommodating portion, and the sliding element being slidably mounted on the base board. The second sliding apparatus is slidably disposed in the accommodating portion and includes a main body and a reacting portion connecting the main body, the main body being capable of sliding in and out of the accommodating portion from the opening. When the main body slides out of the opening, the sliding element is concurrently and separately pulled by the reacting portion to the first position, and when the main body slides into the accommodating portion, the sliding element is concurrently and separately pushed by the reacting portion to the second position.
