Solution Overview

Problem

Existing connectors for circuit boards are difficult to position and secure due to their small size, making soldering challenging, and often result in a permanent connection that is hard to remove, while alternative connectors can be expensive or fragile.

Innovation Solution

A connector system comprising a body with alignment members and contact elements that extend through alignment holes in the circuit board, combined with a retention device featuring a supporting element and sockets to securely attach and detach from the board without soldering, allowing for temporary or permanent connections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If connectors are soldered to circuit boards, then a secure connection is achieved, but the connection becomes permanent and difficult to remove

Engineering Contradiction:
Improveconnection securityVSAvoidremoval ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The connector system is divided into separate components: a connector device with alignment members and contact elements, and a retention device with sockets. This segmentation allows the connector to be securely attached yet easily removed by separating the two components, resolving the contradiction between secure connection and ease of removal.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The retention device provides a dynamic connection mechanism where alignment members can be inserted into and removed from sockets. This dynamic system allows the connection to transition between secured and removed states, enabling both secure attachment during operation and easy removal when needed.

Inventive Principle:
Principle #15Dynamics

2Volume of moving object

If connectors are made small in size, then space efficiency is improved, but positioning and soldering become difficult

Engineering Contradiction:
Improveconnector sizeVSAvoidpositioning difficulty
Core Design Contradiction:
Volume of moving objectVSEase of manufacture

Solution Approach 1:

The alignment members extend through the circuit board in the vertical dimension, providing positioning accuracy without increasing the horizontal footprint of the connector. This dimensional approach allows small connectors to be precisely positioned during assembly by engaging alignment members with alignment holes in the board.

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

3Ease of operation

If alternative connectors are used instead of soldering, then removal ease is improved, but cost or fragility increases

Engineering Contradiction:
Improveremoval easeVSAvoidconnection security
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The alignment members and sockets are designed to work together as a self-contained retention system. The alignment members automatically engage with the sockets to provide secure retention without requiring additional fasteners or complex mechanisms, achieving both ease of removal and connection security.

Inventive Principle:
Principle #25Self-service
