Safety Socket with Torsion Spring Protective Block
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sockets lack protective structures, allowing elongated objects to easily insert and potentially cause damage or hazardous electric shocks, especially in environments with young children.
Innovation Solution
A safety socket design featuring a stop-blocking structure with a torsion rotating spring and protective block body, including stop bumps and guiding slopes, prevents foreign objects from entering the socket holes, ensuring the internal structure is protected and safe.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional socket without protective structure is used, then the socket structure is simple and easy to manufacture, but elongated objects can easily insert into the socket hole causing damage or electric shock hazards
Solution Approach 1:
The protective block body is pre-positioned in the groove chamber with stop bumps that protrude into the socket holes before any foreign object insertion attempt. This preliminary blocking action prevents foreign objects from reaching the conductive components, resolving the contradiction by providing safety protection without requiring complex active detection or response mechanisms.
Solution Approach 2:
The protective block body acts as an intermediary element between the foreign object and the conductive components. The stop bumps on the protective block body serve as a mechanical mediator that physically blocks foreign objects before they can contact the energized parts, achieving safety protection while maintaining relatively simple device structure.
2Object-affected harmful factors
If a protective structure is added to the socket, then safety protection against foreign objects is improved, but the device complexity increases
Solution Approach 1:
The protective structure is segmented into distinct functional elements: the protective block body, stop bumps, guiding slopes, and torsion rotating spring. This segmentation allows each component to perform its specific function independently while keeping the overall structure relatively simple. The stop bumps specifically address foreign object intrusion, while the spring provides reset functionality.
Solution Approach 2:
The torsion rotating spring provides self-service by automatically resetting the protective block body to its blocking position after a plug is removed. This self-resetting mechanism eliminates the need for manual intervention or complex control systems, achieving effective foreign object protection while maintaining simple device structure.
3Reliability
If stop bumps are configured in the socket holes to block foreign objects, then safety protection is improved, but the ease of operation for legitimate plug insertion may be affected
Solution Approach 1:
The protective block body is designed to be dynamically movable rather than fixed. The torsion rotating spring enables the block body to shift position based on the applied force. When a legitimate plug is inserted, the force pushes the stop bumps aside and the block body rotates, allowing plug insertion. When a foreign object is inserted, the block body rotates to block it. This dynamic behavior resolves the contradiction between foreign object blocking and ease of legitimate operation.
Solution Approach 2:
The system changes the positional parameter of the protective block body based on the type of object inserted. For legitimate plugs, the block body moves to a retracted position allowing insertion. For foreign objects, the block body remains in or returns to the blocking position. This parameter change approach enables the structure to adapt its blocking behavior based on the insertion force and object characteristics.
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
Effectively prevents damage to the socket and reduces the risk of electric shocks and fires by blocking elongated objects from entering the socket holes, enhancing safety, especially in environments with young children.
Implementation Method 1
a torsion rotating spring, located within the groove chamber and having a fixation end fixed to the case component and a torsion rotating end, in which the torsion rotating end may rotate relatively to the fixation end as the center of the circle upon being affected by external force, and return to its original position once the external force is removed

AI summary
A safety socket is disclosed, comprising a socket body, an outer mold sleeve, a torsion rotating spring and a protective block body, and when any foreign object may be potentially inserted into the socket body, the foreign object will be effectively blocked by the protective block body such that it cannot smoothly enter therein, thus achieving the feature of safety protection.
