Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demand for board mating connectors in mobile communication repeaters, driven by 5G wireless communication, leads to higher costs and increased mating heights, necessitating a more affordable and compact solution.
Innovation Solution
A board mating connector design featuring a conductive first body part with a hollow portion, a conductive signal contact part with embedded springs, a non-conductive dielectric part, and a conductive second body part with a ground contact part that is formed by bending a metal plate to provide elasticity, reducing the need for separate components and minimizing height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple board mating connectors are used to increase data transmission capacity, then the communication capability is improved, but the cost burden increases
Solution Approach 1:
The ground contact part integrates the ground signal transmission function directly into the contact structure, eliminating the need for separate ground connection components. This merging of functions reduces the total component count and assembly complexity, thereby lowering manufacturing costs while maintaining the required communication capability
2Reliability
If conventional board mating connector structure is used, then the ground contact is ensured, but the mating height increases
Solution Approach 1:
Instead of extending the ground contact part vertically to ensure ground contact, the invention inverts the approach by making the ground contact part extend laterally along the signal contact part. This horizontal extension achieves reliable ground contact while minimizing the vertical mating height
Solution Approach 2:
The ground contact part is nested along the outer surface of the signal contact part, with the ground contact portion extending horizontally from the signal contact part. This nested configuration allows both signal and ground contacts to be achieved within a compact vertical profile, reducing mating height while ensuring reliable electrical connection

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 design reduces the cost and mating height of the board mating connector by integrating elasticity into the ground contact part and optimizing the structural components, thereby addressing the market's need for a cheaper and lower-profile solution.
