Foolproof Connector Interface for Solar Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing connector systems for solar panels are inconvenient to assemble and disassemble, leading to inefficiencies and potential damage during maintenance, requiring multiple connections and welding, which results in wasted time and material.
Innovation Solution
A foolproof electrical connector interface system comprising a 2-pin connector with a male and female plug, fixing plates with hooks, and waterproof junction boxes, allowing for rapid concatenation and convenient assembly and disassembly by eliminating the need for disassembling the panel for replacement, with a buckle and clamping slot for secure connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate connectors are used for each wire connection, then electrical connection tightness is improved, but device complexity and installation time increase
Solution Approach 1:
The patent combines multiple separate connectors into a single integrated connector assembly that handles both wire connections simultaneously. The connector includes multiple connection terminals housed in one unit, allowing both electrical connections to be established at once rather than requiring separate connectors for each wire, thereby reducing overall device complexity while maintaining connection reliability.
Solution Approach 2:
The connector is designed as a multi-functional component that simultaneously performs multiple electrical connection functions. It includes various connection terminals (such as welding terminals and cable glands) that can handle different wire types and connection methods within a single device, eliminating the need for multiple specialized connectors and reducing installation steps.
2Reliability
If panel disassembly is required for connector replacement, then connection security is improved, but maintenance time and risk of damage increase
Solution Approach 1:
The connector system is segmented into modular components that can be independently replaced. The connector assembly is designed as a separate, self-contained unit that interfaces with the panel through standardized mounting mechanisms, allowing the connector itself to be replaced without disassembling the panel structure. This segmentation enables easy maintenance while maintaining secure connections during normal operation.
Solution Approach 2:
The connector is pre-assembled with all necessary wiring and connection terminals before installation on the panel. This preliminary preparation allows the complete connector assembly to be installed as a single unit using simple mounting operations, and later replaced in the same manner without requiring panel disassembly. The pre-assembly ensures all connections are secure before the connector is even installed on the panel.
3Reliability
If multiple separate connection operations are performed, then connection reliability is improved, but installation time and labor cost increase
Solution Approach 1:
The connector integrates multiple connection functions into a single assembly that can be installed in one operation. It includes multiple terminals, cable glands, and wiring connections all housed in one unit that mounts to the panel simultaneously, eliminating the need for multiple separate installation steps and significantly improving installation efficiency while maintaining reliable connections.
Solution Approach 2:
All connection terminals, wiring, and internal components are pre-assembled and configured within the connector housing before installation. This preliminary action ensures that when the connector is mounted to the panel, all electrical connections are established simultaneously in a single operation, rather than requiring multiple sequential connection steps, thereby improving productivity without compromising connection reliability.
