Power Device Spring Clamp Position Limiting Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power supplies lack a security mechanism, leading to accidental disconnection and potential damage when the plug is connected to the receptacle and the power supply is still operational, as there is no structural prevention against the chassis being pulled or the power supply being removed.
Innovation Solution
A power device with a security configuration that includes a housing, a receptacle, a spring clamp, and a position limiting element, where the position limiting element is positioned between the spring clamp and the receptacle, constraining the spring clamp and plug when connected, preventing accidental removal during operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the power supply is fixed in the chassis using a spring clamp, then the power supply can be easily installed and removed, but the power supply can be accidentally disconnected during operation
Solution Approach 1:
The patent introduces a position limiting element as an intermediary component between the spring clamp and the receptacle. This element acts as a mediator that physically blocks the spring clamp from moving beyond a certain position, thereby preventing accidental disconnection while preserving the ease of intentional installation and removal operations
Solution Approach 2:
The position limiting element is pre-installed in the receptacle to create a preliminary counter-action against the spring clamp's movement. This preliminary anti-action prevents the harmful disconnection before it can occur, while allowing legitimate installation and removal operations to proceed
2Device complexity
If no security mechanism is provided on the power supply, then the structure remains simple, but accidents occur when the chassis is pulled or power supply is removed during operation
Solution Approach 1:
The patent divides the security function into a separate, dedicated component - the position limiting element - rather than integrating security features into the existing spring clamp or receptacle structures. This segmentation adds minimal complexity while effectively addressing the harmful factor of accidental disconnection
Solution Approach 2:
The position limiting element serves as a simple intermediary component that provides security without requiring complex mechanisms. It is a straightforward physical barrier that prevents excessive movement of the spring clamp, thereby eliminating accidental disconnection risks while maintaining overall structural simplicity

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 security configuration effectively prevents accidental disconnection and damage by ensuring the power device remains securely attached to the chassis, even when the plug is inserted, thereby preventing power outages and related accidents.

AI summary
A power device suited for being assembled in a chassis and connected with a plug is provided. The power device includes a housing, and a receptacle, a spring clamp, a position limiting element disposed on the housing. The plug is removably connected to the receptacle. The spring clamp has a moving end. The position limiting element is located between the spring clamp and the receptacle. The position limiting element and the moving end of the spring clamp are linked together to move between a first position and a second position relative to the housing. When the plug connects to the receptacle, the position limiting element is interfered with the plug and the spring clamp simultaneously so that the spring clamp is constrained at the first position.
