Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power supply connection devices lack waterproofing and safety features, leading to potential electric shocks, especially when used with conductive objects or in wet conditions.
Innovation Solution
A power supply connection structure device comprising a first and second electrical connection unit and a control unit, where the electric circuit is only connected to the power source when the control unit activates the micro-switches, ensuring safe operation and waterproofing through a partition arrangement and waterproof seal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional power supply connection devices are used without control units, then the device structure is simple and easy to manufacture, but the device lacks waterproofing and safety features leading to potential electric shocks
Solution Approach 1:
A control unit is introduced as an intermediary component between the electrical connection units and the power source. This control unit includes micro-switches that mediate the connection process, enabling safety control and waterproofing functions without directly exposing the user to complex internal mechanisms.
Solution Approach 2:
The device is segmented into distinct functional modules: electrical connection units for power input, a control unit with micro-switches for safety control, and a partition arrangement with waterproof seal for protection. This segmentation allows each component to perform its specific function while maintaining overall system safety and reliability.
2Productivity
If the electric circuit is always connected to the power source, then the device can continuously supply power, but the risk of electric shock increases when conductive objects are inserted
Solution Approach 1:
The electrical connection is made dynamic through the control unit with micro-switches. Instead of a permanent static connection, the circuit connection state changes dynamically based on whether the plug is properly inserted and the ground connection is established. This dynamic control allows power supply when safe and disconnection when hazardous conditions are detected.
Solution Approach 2:
The control unit performs preliminary safety verification through the micro-switches before allowing the electric circuit to connect to the power source. The ground connection must be established first, and the micro-switches verify this condition in advance, preventing electric shock by blocking power connection until safety conditions are met.
3Reliability
If waterproofing features are added to the power supply connection device, then electric shock prevention is improved, but the device structure and manufacturing complexity increase
Solution Approach 1:
A waterproof seal is introduced as a flexible protective barrier within the partition arrangement. This seal acts as a thin film that prevents water penetration into the electrical components while maintaining a relatively simple overall device structure. The seal can be integrated into the existing housing design with minimal additional manufacturing steps.

AI summary
The present invention relates to a power supply connection structure device, a manufacturing method thereof and a circuit connection method. The device, which is used to connect an electrical appliance to a power supply, includes a live wire and neutral wire connection unit and a control unit, the control unit is switched between an activation state and an idle state, when the control unit is in the idle state, the live wire and neutral wire connection unit is not connected to the power supply; and when the control unit is in the activation state, the control unit connects the live wire and neutral wire connection unit to the power supply, thus, by using the control unit, the power supply connection structure device is safe to use, is waterproof and prevents from electric shock. The control unit may include a push member located in a ground wire plughole and operable to turn on two micro-switches, one for the live terminal, the other one for the neutral terminal.
