Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the wire harness fixing device uses a fixed configuration for holding electric wire members, then the structural simplicity is maintained, but the adaptability to different vehicle equipment configurations is reduced

Engineering Contradiction:

Improveadaptability to different electric wire configurationsVSAvoidstructure complexity of fixing device

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The fixing device is divided into a first holding member with a fixed part and a second holding member with a holding part. The second holding member can be detachably attached to the first holding member, allowing the electric wire members to be segmented into different groups that can be independently configured based on vehicle equipment variations.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The second holding member is designed to be detachably attachable to the first holding member, transforming the fixed configuration into a dynamic one. This allows the holding structure to be reconfigured by attaching or detaching the second holding member according to different vehicle equipment configurations.

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If the wire harness fixing device uses a fixed configuration, then the manufacturing simplicity is maintained, but the ease of changing electric wire member configurations is reduced

Engineering Contradiction:

Improveease of changing electric wire configurationsVSAvoidmanufacturing simplicity

Core Design Contradiction:

Ease of operationVSEase of manufacture

Solution Approach 1:

By segmenting the holding function into a first holding member and a second holding member with detachable connection, the device allows easy reconfiguration of electric wire members without requiring complete disassembly, thus improving ease of operation while maintaining manufacturing simplicity through modular design.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The first holding member serves as a universal base that can accommodate different configurations by selectively attaching the second holding member. This multi-functional design allows the same base structure to support various electric wire configurations, improving ease of operation without complicating manufacturing.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If the second holding member is made detachable from the first holding member, then the adaptability to different vehicle configurations is improved, but the device complexity increases

Engineering Contradiction:

Improveconfigurability for different vehicle gradesVSAvoidcomplexity of holding member structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The detachable connection between the first and second holding members segments the device into independent functional modules. This segmentation enables adaptability to different vehicle configurations by selectively combining modules, while the modular nature actually simplifies the overall device complexity compared to a fully integrated fixed structure.

Inventive Principle:

Principle #1Segmentation
