Socket Safety Shutter Structure to Reduce Shake and Boss Wear
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing socket safety shutters are prone to shaking and wear due to simple opening mechanisms, posing a safety hazard when a child accidentally inserts a finger or conductor into the power jack, and their design compromises structural integrity.
Innovation Solution
A protection device with a reinforcing plate, bent limiting baffle plate, and sliding protection plates that avoid direct contact with the plug, reducing shaking and maintaining structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple safety shutter design is used, then the device complexity is reduced and ease of manufacture is improved, but the reliability deteriorates as the shutter is prone to accidental opening
Solution Approach 1:
The safety shutter is divided into two separate protection plates (first protection plate and second protection plate) that can move independently. Each plate is controlled by its own reset spring and limited by its own limiting baffle plate, creating a segmented control system that prevents accidental opening while maintaining simple overall design
Solution Approach 2:
The limiting baffle plates are pre-positioned to limit the movement range of the protection plates before accidental opening can occur. The reset springs are pre-loaded to automatically return the plates to the closed position, providing preliminary protective action that prevents the harmful effect of accidental opening
2Adaptability or versatility
If frequent plugging and unplugging operations are performed, then the adaptability and ease of operation are improved, but the strength deteriorates due to wear of the boss
Solution Approach 1:
The function of limiting protection plate movement is extracted from the boss and transferred to separate limiting baffle plates. This removes the wear-inducing contact between the boss and plugs, allowing frequent operations without deteriorating boss strength while maintaining operational flexibility
Solution Approach 2:
The limiting baffle plates serve as intermediary elements between the boss and the protection plates. They absorb the wear from frequent plugging and unplugging operations, protecting the boss from direct contact and wear while still enabling the necessary movement for plug operations
3Ease of manufacture
If a straight limiting baffle plate is used, then the ease of manufacture is improved, but the stability deteriorates as the protection plate shakes greatly during movement
Solution Approach 1:
The limiting baffle plate is designed with a bent structure instead of a straight line, creating a curved path that guides the protection plate movement. This curved geometry reduces shaking and improves stability during operation while remaining manufacturable through standard bending processes

Function Achieved in This Case
Enhances safety by preventing accidental contact and maintaining the structural integrity of the socket safety shutter, reducing wear and enhancing reliability.
Implementation Method 1
the reset springs on both sides of the plastic plates push the plastic plates to close the power jack

AI summary
A protection device for a socket safety shutter includes a device body having a boss; a reinforcing plate is arranged on one side of the boss, and is integrated with the boss; a limiting baffle plate is arranged on one side surface of the device body; and the limiting baffle plate is of a bent structure. The reinforcing plate is arranged on one side of the boss, so that direct contact between a side surface of the boss and a plug is avoided, which does not affect the intensity of the boss. In addition, the limiting baffle plate of the bent structure is arranged. The original limiting baffle plate is a straight plate, which may shake greatly when a protection plate I of the limiting baffle plate moves. Therefore, using the bent L-shaped structure can reduce shaking, and a volume of the device body is reduced on the original basis.
