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

VSEngineering 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

Engineering Contradiction:
Improvedata transmission capacityVSAvoidcost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

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

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If conventional board mating connector structure is used, then the ground contact is ensured, but the mating height increases

Engineering Contradiction:
Improveground contactVSAvoidmating height
Core Design Contradiction:
ReliabilityVSLength of moving object

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

Inventive Principle:
Principle #13The other way round (Inversion)

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

Inventive Principle:
Principle #7Nested doll (Nesting)
