Solution Overview

Problem

Existing connectors fail to securely and stably connect two opposing printed circuit boards or similar devices, particularly in applications requiring end-to-end or edge-to-edge connections, such as in avionics, due to lack of compatibility with thin boards and flex circuits.

Innovation Solution

A connector system that mates the edges of two printed circuit boards or flex circuits using electrically conductive transverse members with a mechanical locking feature, allowing for stable end-to-end connections and enabling bussing interconnection between adjacent boards, with features like dielectric housing and hook-like structures for secure attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing connectors are used to connect two opposing printed circuit boards, then connection is achieved, but the connection is not secure or stable enough for certain applications

Engineering Contradiction:
Improveconnection stabilityVSAvoidcompatibility with thin boards and flex circuits
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The connector is divided into two separate halves (first connector half and second connector half) that mate together. Each half can be independently attached to opposing printed circuit boards, allowing the connection to be segmented and adapted to thin boards and flex circuits while maintaining secure connection through the mating halves

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connector halves are designed to nest within recesses in the printed circuit boards. The first connector half nests in a recess of the first board, and the second connector half nests in a recess of the second board, creating a stable nested configuration that secures the connection

Inventive Principle:
Principle #7Nested doll (Nesting)

2Adaptability or versatility

If existing connectors are used, then connection between boards is achieved, but they cannot accommodate two opposing printed circuit boards positioned adjacent to one another

Engineering Contradiction:
Improvecompatibility with opposing boardsVSAvoidconnection security
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The connector system is segmented into two separate halves that can independently engage with opposing printed circuit boards. This segmentation allows the connector to accommodate boards positioned adjacent to one another while maintaining secure connection through the mating connector halves

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connector extends in multiple dimensions with protrusions and recesses that engage in perpendicular directions. The connector halves extend from opposing boards and mate together, creating a three-dimensional connection that secures boards positioned adjacent to one another

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Reliability

If a secure mechanical connection is implemented, then connection stability is improved, but device complexity increases

Engineering Contradiction:
Improveconnection securityVSAvoidconnector structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The connector halves are designed to merge with each other when mated, combining the two separate connector halves into a unified connection structure. This merging provides secure mechanical connection while avoiding the complexity of more elaborate locking mechanisms

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The connector halves are designed to self-align and self-secure through their protrusions and recesses. The mechanical locking feature automatically engages when the connector halves are mated, providing secure connection without requiring additional complex fastening operations

Inventive Principle:
Principle #25Self-service
