Electric Mouse Trap Locking Pressing Device to Prevent Escape
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional electric mouse traps fail to effectively capture mice as they struggle and escape due to instinctive reactions that cause them to disengage from the conductive sheets, leading to a low success rate.
Innovation Solution
A mouse trap design featuring a locking mechanism that secures the mouse pressing device after shocking, preventing the mouse from disengaging from the conductive elements, enhancing the electric shock's effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional electric mouse trap uses conductive sheets to deliver electric shock, then the mouse receives electric shock, but the mouse can turn over or jump up to release from the conductive sheets and escape
Solution Approach 1:
The pressing device is designed to be movable rather than fixed, allowing it to dynamically respond to the mouse's movements. The device can press down on the mouse to maintain contact with conductive sheets during struggle, then release after trapping is complete, adapting its state based on operational needs.
Solution Approach 2:
The pressing device acts as an intermediary between the mouse and the conductive sheets. It ensures continuous contact by physically pressing the mouse against the sheets, mediating the interaction to prevent the mouse from escaping while avoiding direct complex mechanisms in the electrical circuit.
2Reliability
If the mouse pressing device is made movable to press the mouse, then the mouse remains in contact with conductive elements, but the device requires a locking mechanism to control movement
Solution Approach 1:
The locking mechanism is designed to automatically engage and disengage based on the operational state. When the mouse triggers the trap, the system automatically locks the pressing device in position; after operation, it automatically releases. This self-service functionality reduces the need for complex manual control mechanisms.
Solution Approach 2:
The locking mechanism changes the positional parameter of the pressing device from movable to fixed during operation. By controlling the state transition of the locking element, the system adjusts the degree of freedom of the pressing device, enabling it to maintain contact when needed and release when operation is complete.
3Reliability
If the locking element is engaged with the mouse pressing device, then the mouse pressing device movement is limited, but the locking element must be released to allow the mouse to be pressed
Solution Approach 1:
The locking mechanism operates periodically, alternating between locked and unlocked states. It locks the pressing device during operation to maintain stability, then unlocks to allow resetting and repositioning. This periodic cycling between constrained and free states balances stability requirements with operational flexibility.
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 locking mechanism ensures the mouse remains in contact with the conductive elements, improving the capture and shock mortality rate by preventing escape.
Implementation Method 1
the electric shock mechanism uses high-voltage micro-current to make them unable to escape
Implementation Method 2
the locking element is capable of moving between a locked position and an unlocked position, and is engaged with the mouse pressing device when the locking element is located in the locked position, so as to limit the movement of the mouse pressing device
