Solution Overview

Problem

Hybrid cars experience heat buildup and potential sparking at contact points due to high electric current flow in electric connectors, which can lead to explosions.

Innovation Solution

A connector terminal design featuring two or more symmetrically arranged contact points with a bent portion and movable free ends, allowing for even heat dispersion across multiple contact points during electrical connections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If high electric current is applied to the terminals, then the electric current flows through a single contact point, but an amount of heat generated from the contact point is increased

Engineering Contradiction:
Improveelectric currentVSAvoidheat generated
Core Design Contradiction:
PowerVSTemperature

Solution Approach 1:

The coupling terminal unit is divided into multiple contact points (first contact point and second contact point) instead of using a single contact point. This segmentation allows the electric current to be distributed across multiple contact points, reducing the heat generated at each individual contact point while maintaining the required power transmission capability.

Inventive Principle:
Principle #1Segmentation

2Device complexity

If a single contact point is used, then the structure is simple, but sparks may occur from the contact point which may result in an explosion

Engineering Contradiction:
Improvecontact point structureVSAvoidsafety
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The contact interface is segmented into multiple contact points (first contact point between first coupling terminal and first connection terminal, second contact point between second coupling terminal and second connection terminal). This segmentation reduces the risk of sparking and explosion by distributing the electrical connection across multiple points, thereby improving safety while maintaining structural simplicity.

Inventive Principle:
Principle #1Segmentation

3Temperature

If multiple contact points are used, then heat dispersion is improved, but the device complexity increases

Engineering Contradiction:
Improveheat dispersionVSAvoidterminal structure
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The coupling terminal unit is segmented into multiple contact points achieved through symmetric arrangement of coupling terminals and connection terminals. The first coupling terminal part contacts with the first connection terminal part at a first contact point, and the second coupling terminal part contacts with the second connection terminal part at a second contact point. This segmentation improves heat dispersion while maintaining structural simplicity through symmetry.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The coupling terminal unit employs symmetric arrangement where the first coupling terminal part and second coupling terminal part are symmetrically positioned, and similarly for the connection terminals. This symmetry allows multiple contact points to be achieved in a regular, simple pattern rather than requiring complex asymmetric structures.

Inventive Principle:
Principle #4Asymmetry

AI summary

A connector terminal includes a connection body terminal unit and a coupling terminal unit receiving the connection body terminal unit. The coupling terminal unit having an upper coupling terminal part symmetrically arranged with a lower coupling terminal part. Each of the upper and lower coupling terminal parts includes a fixed end, a free end, and a bent portion. The free end is movable and is positioned opposite the fixed end. The fixed end includes a plurality of contact points. The bent portion is positioned between the fixed end and the movable free end, and is disposed along a front side of each of the upper and lower coupling terminal parts.
