Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing housings for telecommunications devices with connections to printed circuit boards face complications due to soldering issues such as breakage and cold soldering, which complicate the industrial process and increase the probability of connection failure.
Innovation Solution
A housing with a connection system that uses a conductive strip and a conductive film on a printed circuit board, where the conductive strip makes galvanic contact with the film through pressure, eliminating the need for soldering and enhancing connection security with an elastic conductive lamella and insulating sleeve to prevent short circuits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If soldered connections are used for connecting the circuit board, then electrical connection is established, but the industrial process becomes complicated and connection reliability decreases due to soldering issues
Solution Approach 1:
The patent extracts and eliminates the soldering process from the connection system. Instead of using traditional soldered connections between the circuit board and housing, the invention introduces a separate connector assembly with contact elements that establish electrical connections without requiring soldering, thereby simplifying the industrial process while maintaining connection reliability
Solution Approach 2:
The patent introduces an intermediary connector assembly that mediates between the circuit board and the housing. This connector includes contact elements on the circuit board side and corresponding contact surfaces in the housing, creating an intermediate connection layer that eliminates the need for direct soldered connections between the housing and circuit board
2Reliability
If a small contact surface is used for galvanic contact, then the connection structure is simple, but the probability of connection failure increases when handled improperly
Solution Approach 1:
The patent segments the connection system into multiple contact elements distributed across the connector assembly. Instead of relying on a single small contact point, the connection is divided into multiple contact elements that can be arranged in arrays or patterns, providing redundancy and reducing the impact of any single contact point failure
Solution Approach 2:
The patent applies local quality by creating specific contact zones with optimized properties. The contact elements are designed with specific geometries and material properties at the contact locations, while other parts of the connector have different properties optimized for their specific functions such as mechanical support or insulation
