Solution Overview
Problem
In household appliances like refrigerators, electrical connections for moving parts such as LED lamps on shelves are costly and prone to damage during installation, leading to potential connection failures.
Innovation Solution
An electrical connection assembly featuring a connector mounted on a circuit board with an elastic arm and connection pin that contacts an electrical contact pad on a moving bracket, eliminating the need for a separate connector on the moving part, thus reducing costs and minimizing damage risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a connector is provided on the moving shelf to mate with the connector on the circuit board, then electrical connection is achieved, but the cost increases and the connector may be damaged during insertion
Solution Approach 1:
The patent extracts the connector from the moving shelf and relocates it to the stationary circuit board. Only the elastic arm (contact element) remains on the moving shelf, while the main connector body is mounted on the circuit board. This extraction reduces the complexity and damage risk on the moving shelf while maintaining electrical connection reliability.
Solution Approach 2:
The patent inverts the traditional connector arrangement by placing the connector on the stationary circuit board rather than on the moving shelf. The elastic arm on the moving shelf acts as the male contact, while the connector on the circuit board provides the female receptacle, reversing the conventional approach and improving reliability.
2Reliability
If a connector is provided on the moving shelf, then electrical connection is achieved, but the cost increases
Solution Approach 1:
The patent extracts the expensive connector component from the moving shelf and places it on the stationary circuit board. Only the simple elastic arm remains on the moving shelf, significantly reducing the manufacturing cost of the moving shelf assembly while maintaining electrical connection functionality.
Solution Approach 2:
The patent replaces the expensive connector on the moving shelf with a simple, inexpensive elastic arm that can be easily manufactured and replaced if needed. The main connector investment is made in the stationary circuit board where it provides long-term service.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution provides a cost-effective and reliable electrical connection for moving parts without the need for a connector on the moving bracket, enhancing durability and ease of use by eliminating the risk of connector damage during installation.
Implementation Method 1
The elastic arm extends out from a surface of the housing and electrically contacts an electrical contact pad on a moving bracket

AI summary
An electrical connection assembly includes a circuit board and a connector mounted on the circuit board. The connector has a housing and a contact received in the housing. The contact has an elastic arm extending out from a surface of the housing and a connection pin extending out from a side face of the housing. The elastic arm electrically contacts an electrical contact pad on a moving bracket and the connection pin electrically contacts the circuit board.
