Plug-In Charging Station Mounting Frame for Waterproof Wiring

Solution Overview

Problem

Traditional charging stations require cumbersome and complex wiring processes, which can compromise waterproofing and lead to installation inefficiencies and potential device failures due to the need to open covers and manage screws for sealing.

Innovation Solution

A charging station design featuring an open-type accommodating cavity with a wire compartment on the mounting frame, allowing for plug-and-unplug connections between the charging station body and terminal connector, eliminating the need to open covers and incorporating a flow introduction structure to prevent water ingress, using male and female connectors for simplified and efficient installation and power connection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional charging stations use covered wire compartments requiring screw removal and sealing ring installation, then waterproofing can be maintained, but wiring steps become cumbersome and complex, reducing installation efficiency

Engineering Contradiction:

Improvewaterproofing performanceVSAvoidinstallation efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The charging station is divided into separate modular components: a waterproof box containing the terminal connector and a separate wire compartment on the mounting frame. This segmentation allows the waterproof box to maintain its sealed integrity while the wire compartment provides easy access for wiring operations, resolving the contradiction between waterproofing and installation efficiency.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A socket is introduced as an intermediary component between the terminal connector in the waterproof box and the external wiring. The socket is installed in the wire compartment and connects to the terminal connector through a plug connection, allowing wiring to be performed externally without opening the waterproof box, thus maintaining both waterproofing and installation efficiency.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If covers are opened for wiring in traditional charging stations, then wiring access is provided, but original waterproof performance may be destroyed due to improper screw installation or insufficient sealing distance

Engineering Contradiction:

Improvewiring accessibilityVSAvoidwaterproof performance

3Strength

If screws are used to secure covers in traditional charging stations, then structural integrity is maintained, but improper locking can lead to waterproof failure or device failure from inner circuit board exposure

Engineering Contradiction:

Improvestructural integrityVSAvoidwaterproof and device safety

Core Design Contradiction:

StrengthVSReliability

Solution Approach 1:

The traditional screw-based mechanical fastening system is replaced with a plug-socket connection system. The socket in the wire compartment plugs into the terminal connector in the waterproof box, providing both electrical connection and mechanical coupling without requiring screws or seals, thus eliminating the risk of improper fastening while maintaining structural integrity and waterproofing.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
