Waterproof Socket Isolation Chamber for Moisture-Safe Plug Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sockets and power strips lack reliable moisture-proof and anti-electric shock features, allowing moisture to enter during plug insertion and causing damage to internal circuits.
Innovation Solution
A waterproof socket design with a housing divided into non-communicating first and second installation spaces, featuring a socket circuit in the first space and an adapter in the second, with a triggering component enabling sequential electrical connections and sealed by sealing elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a waterproof splash cover and sealing pad are installed on the socket, then moisture-proof and waterproof functions are improved, but the reliability is worsened because moisture can still enter during plug insertion and unplugging
Solution Approach 1:
The installation cavity is divided into a first installation space for the socket circuit and a second installation space for the adapter, separated by an isolation chamber. This segmentation prevents moisture that enters during plug insertion from reaching the socket circuit, as the isolation chamber acts as a barrier between the wet environment (second space) and the sensitive circuit (first space).
Solution Approach 2:
The isolation chamber serves as an intermediary structure between the socket circuit and the adapter area. It provides a transition zone that blocks moisture migration while still allowing the triggering component to function, thus protecting the circuit without completely isolating the plug insertion area.
2Reliability
If a leakage-and-short circuit protection device and anti-touch protection door are provided, then safety functions are improved, but the device complexity increases
Solution Approach 1:
The isolation chamber combines multiple functions into a single structure: it acts as both a waterproof barrier and a mounting structure for the triggering component. The triggering component itself integrates both the electrical connection function and the circuit triggering function, reducing the need for separate protection devices and simplifying the overall structure.
Solution Approach 2:
The triggering component serves multiple purposes: it provides the electrical connection between the adapter and socket circuit, acts as a mechanical trigger for the circuit, and its movable part penetrating the isolation chamber provides both connection and sealing functionality. This multi-functionality reduces the number of separate components needed.
3Reliability
If the socket circuit is sealed in a separate space, then waterproofing is improved, but the ease of operation is worsened due to complex plug insertion triggering mechanism
Solution Approach 1:
The triggering component utilizes the natural insertion motion of the plug to automatically activate the circuit connection. As the plug is inserted into the adapter, the movable part is naturally pushed through the isolation chamber, making contact with the socket circuit and completing the connection without requiring any additional user actions or complex manual triggering mechanisms.
