Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual connection of wire harness is used, then ease of operation is improved, but productivity deteriorates due to time-consuming inspection process

Engineering Contradiction:

Improvemanual connection easeVSAvoidinspection efficiency

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The system enables automatic connection and inspection where the charge and discharge inspection part automatically connects to the battery module via the fixed wire harness, eliminating the need for manual operator intervention in the connection process while maintaining operational simplicity

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The manual mechanical connection process is replaced with an automatic connection system where the fixed wire harness structure enables automated engagement with the charge and discharge inspection part, substituting human labor with automated mechanical systems

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If wire harness is left loose during transfer, then ease of operation is improved, but reliability deteriorates due to wire harness flowage and potential damage

Engineering Contradiction:

Improvetransfer flexibilityVSAvoidwire harness integrity

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The wire harness is pre-fixed to the battery module using the first fixing member before the transfer process begins, preventing flowage and potential damage during subsequent handling and inspection operations

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The first fixing member acts as an intermediary component that secures the wire harness to the battery module, providing a reliable connection that prevents direct contact and potential damage between the wire harness and external objects during transfer

Inventive Principle:

Principle #24Intermediary (Mediator)
