Solution Overview

Problem

The existing connector systems for circuit boards are complex and require multiple components, including crimp terminals and housings, which complicates the process of connecting wires to terminals and increases the number of components needed.

Innovation Solution

An electronic device with a terminal that integrally includes a positional displacement prevention part, allowing the wire to be directly bonded to the terminal while preventing positional displacement, thus simplifying the connection process and reducing the number of components required.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a connector system with crimp terminal and housing is used, then positional displacement of the lead part can be prevented, but the connection process becomes complicated and the number of components increases

Engineering Contradiction:

Improvepositional displacement preventionVSAvoidnumber of components

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent combines the terminal body and the positional displacement prevention part into a single integrated terminal structure. The terminal includes a body portion with a wire bonding part and a positional displacement prevention part that protrudes from the body, eliminating the need for separate crimp terminals and housings while maintaining both electrical connection and positional prevention functions

Inventive Principle:

Principle #5Merging (Combining)

2Manufacturing precision

If a connector system with crimp terminal and housing is used, then positional displacement of the lead part can be prevented, but the connection process becomes complicated

Engineering Contradiction:

Improvepositional displacement preventionVSAvoidconnection process complexity

Core Design Contradiction:

Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The patent merges the terminal body and positional displacement prevention part into one integrated component, allowing the wire to be directly bonded to the terminal body while the protruding positional displacement prevention part prevents misalignment, simplifying the connection process to a single bonding step without separate assembly operations

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The terminal structure is designed to automatically prevent positional displacement through its own geometric features (the protruding positional displacement prevention part fitting into a corresponding recess), eliminating the need for external positioning mechanisms or complex alignment procedures during manufacturing

Inventive Principle:

Principle #25Self-service
