Solution Overview

Problem

Existing electrical connections in electric or hybrid vehicles often require multiple connection bars and direct pin connections, which can lead to stress and damage on electronic cards due to deformation, complicating the secure and efficient power supply to filtering components.

Innovation Solution

An electrical assembly featuring a single connection zone between two electrical connection bars and an electrical conduction part that makes contact with the electronic card, eliminating the need for additional connections and reducing stress through a fixing member and pin configuration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the electronic card is connected directly to the second electrical connection bar by a pin, then electrical power can be supplied to the electronic card, but deformations of the connection bar can cause forces on the card or damage to the pin

Engineering Contradiction:
Improveelectrical supplyVSAvoidforce transmission
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an intermediary connection structure where the electronic card contacts both electrical connection bars simultaneously at a shared connection zone. This distributed contact arrangement acts as a mediator that distributes mechanical forces across multiple contact points, preventing concentrated stress and force transmission that would occur with a single pin connection.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If another connection point is provided on the second electrical connection bar to convey current to the electronic board, then the electronic board can be powered, but the device complexity and number of connections increase

Engineering Contradiction:
Improvepower supply to electronic boardVSAvoidnumber of connections
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges multiple power supply functions into a single connection zone. The electronic card is positioned to make simultaneous contact with both the first and second electrical connection bars at one location, thereby combining multiple electrical connections into a single integrated point and reducing the overall number of connections required.

Inventive Principle:
Principle #5Merging (Combining)
