Switch Module Stop Part Prevents Cover Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-end servers require power supply modules with higher current and efficiency, but traditional modules lack covers, leading to risks of electric shock and short circuits during assembly or testing, necessitating a secure mechanism to prevent improper manual operations.
Innovation Solution
A case with a housing, cover, and switch module featuring a secure mechanism, including a switch-changing element with a pivot part, pressing part, and stop part that rotates to toggle the power supply on or off and prevent cover assembly, ensuring the cover is securely in place or removable based on the switch's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the power supply module is connected to the main board without a cover, then the power supply module can be assembled and function, but electric shock and short circuit risks occur during testing or assembly
Solution Approach 1:
A cover is introduced as an intermediary component between the power supply module and the external environment. The cover physically isolates the electrical components, preventing direct contact that could cause electric shock or short circuits, while still allowing the module to function when properly assembled.
Solution Approach 2:
A secure mechanism with a stop part is designed to prevent the cover from being removed or improperly assembled. The stop part blocks the movement that would expose electrical components, proactively preventing electric shock and short circuit risks before they can occur during testing or assembly operations.
2Object-affected harmful factors
If a secure mechanism with stop part is added to prevent improper operations, then safety against electric shock is improved, but device complexity increases
Solution Approach 1:
The secure mechanism is merged with the existing cover and housing structure. The stop part is integrated into the cover assembly rather than being a separate component, and the pressing switch mechanism is combined with the cover positioning system, reducing overall device complexity while maintaining safety functionality.
Solution Approach 2:
The secure mechanism operates automatically through mechanical interaction between the cover, stop part, and pressing switch. When the cover is properly assembled, the stop part automatically releases to allow cover closure, and the pressing switch automatically engages to lock the position, eliminating the need for additional control systems or complex actuation mechanisms.
3Object-affected harmful factors
If the switch-changing element prevents cover assembly in test position, then accidental assembly is prevented, but ease of operation during testing is reduced
Solution Approach 1:
The switch-changing element is designed to dynamically change its function based on position. In the test position, the stop part extends to prevent cover assembly, blocking accidental operation. When rotated to the non-test position, the stop part retracts to allow normal cover assembly, maintaining ease of operation during legitimate testing procedures.
Solution Approach 2:
Before performing any testing or assembly operations, the operator must first rotate the switch-changing element to the appropriate position. This preliminary action ensures that the stop part is in the correct state (extended or retracted) before the cover is manipulated, preventing accidental assembly while allowing intentional testing when properly prepared.
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 secure mechanism effectively prevents accidental assembly and electrical shocks by ensuring the cover is correctly positioned, automatically switching the power supply off when the cover is removed, thus enhancing safety during testing and assembly.
Implementation Method 1
The switch-changing element is configured to rotate relative to the housing and therefore has a test position and a non-test position
Implementation Method 2
the pressing part presses the pressing switch to make the pressing switch be in the turn-on state
Implementation Method 3
a position of the stop part overlaps the cover position to prevent the cover from being disposed on the housing

AI summary
A case includes a housing, a cover and a switch module with a secure mechanism. The case has an accommodation portion. The cover is disposed on the case to have a cover position. The cover covers the accommodation portion. The switch module including a pressing switch and a switch-changing element is located in the accommodation portion and connected to the housing. The switch-changing includes a first pivot part, a pressing part, and a stop part. The first pivot part pivots the housing. The pressing part and the stop part jut from the first pivot part along different radial directions. The switch-changing element has a test position and a non-test position for rotating relative to the housing. When the switch-changing element locates at the test position, a position of the position of the stop part overlaps the cover position.
