Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power supply connection structures lack waterproofing and safety features, leading to potential electric shocks, especially when used with conductive objects or in wet conditions, posing a risk to individuals.
Innovation Solution
A power supply connection structure device featuring a control unit with micro-switches that only connects the live and neutral wire connection units to the power source when activated, incorporating a waterproof seal and partition arrangement to prevent water ingress and ensure safe usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional power supply connection structure is used, then electrical connection is simple and direct, but waterproofing capability is lacking and electric shock risk increases
Solution Approach 1:
The power supply connection structure is divided into separate components: a housing containing electrical connections, a removable plug, and a waterproof seal. This segmentation isolates electrical components within a protected enclosure, preventing water ingress while maintaining functional electrical connection capability.
Solution Approach 2:
A waterproof seal acts as an intermediary barrier between the electrical connection components and the external environment. The seal prevents direct contact between water and electrical elements, eliminating the electric shock hazard while allowing electrical functionality when properly connected.
2Ease of operation
If electrical connection units are always connected to power source, then power supply is continuous, but electric shock hazard exists when conductive objects are inserted
Solution Approach 1:
The waterproof housing and seal are pre-installed to create a protected environment for electrical connections. This preliminary protective action ensures that even when the device is in use, water cannot reach electrical components, preventing electric shock while maintaining continuous power supply capability.
3Reliability
If waterproof seal is added to power supply connection structure, then waterproofing capability is improved, but device complexity increases
Solution Approach 1:
The waterproof seal is integrated into the housing structure, merging the sealing function with the existing enclosure. This combination approach provides waterproofing without requiring separate, complex sealing mechanisms, thereby improving reliability while minimizing additional complexity.

AI summary
A power supply connection structure device for electrically connecting an electrical appliance to a power source includes a live wire connection unit, a 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 units are not electrically connected to the power supply. When the control unit is in the activation state, the control unit electrically connects the live wire and neutral wire connection units to the power supply. Therefore, by means of the control unit, the power supply connection structure device is safe to use and waterproof and prevents individual from electric shock.
