1Adaptability or versatility

If a wire harness with a complex shape is formed by combining trunk line, sub-wire harness, and optional sub-wire harness to connect various electric components, then connection to various electric components disposed at various locations can be performed, but the structure becomes complicated and the number of bundled electric wires increases leading to increased weight

Engineering Contradiction:

Improveconnection capability to various electric componentsVSAvoidweight of wire harness

Core Design Contradiction:

Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The wire harness is divided into a trunk line portion and multiple branch line portions. The trunk line contains a bundle of electric wires that are commonly used across different vehicle models, while each branch line contains electric wires specific to particular vehicle models or optional components. This segmentation allows the heavy trunk line to be standardized and reused, while only lighter, model-specific branch lines need to be customized and added.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The trunk line is designed with a universal configuration that can serve multiple vehicle models and configurations. The same trunk line with its bundle of electric wires can be used across different vehicle models by simply adding or removing specific branch lines, making the core structure universal and adaptable rather than requiring complete customization for each model.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Power

If the diameter of each electric wire or the number of electric wires increases due to an increase in the number of electric components mounted on a vehicle, then power supply and signal transmission capabilities are improved, but the size of the entire wire harness increases

Engineering Contradiction:

Improvepower supply capabilityVSAvoidsize of wire harness

Core Design Contradiction:

PowerVSVolume of moving object

Solution Approach 1:

The wire harness is divided into a trunk line portion and multiple branch line portions. The trunk line contains a bundle of electric wires that are commonly used across different vehicle models, while each branch line contains electric wires specific to particular vehicle models or optional components. This segmentation allows the heavy trunk line to be standardized and reused, while only lighter, model-specific branch lines need to be customized and added.

Inventive Principle:

Principle #1Segmentation

3Shape

If almost all of electric wires are collected at a trunk line portion of the wire harness, then routing organization is improved, but the number of bundled electric wires increases leading to increased weight

Engineering Contradiction:

Improverouting organizationVSAvoidweight of trunk line portion

Core Design Contradiction:

ShapeVSWeight of moving object

Solution Approach 1:

The wire harness is divided into a trunk line portion and multiple branch line portions. The trunk line contains a bundle of electric wires that are commonly used across different vehicle models, while each branch line contains electric wires specific to particular vehicle models or optional components. This segmentation allows the heavy trunk line to be standardized and reused, while only lighter, model-specific branch lines need to be customized and added.

Inventive Principle:

Principle #1Segmentation

4Adaptability or versatility

If a wire harness has a complex structure or shape, then connection to various electric components is achieved, but it becomes very difficult to add other electric wires to the existing wire harness in the future

Engineering Contradiction:

Improveconnection capabilityVSAvoidease of adding new wires

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The wire harness is divided into a trunk line portion and multiple branch line portions. The trunk line contains a bundle of electric wires that are commonly used across different vehicle models, while each branch line contains electric wires specific to particular vehicle models or optional components. This segmentation allows the heavy trunk line to be standardized and reused, while only lighter, model-specific branch lines need to be customized and added.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The wire harness structure is designed to be dynamically adaptable. New electric wires can be easily added by simply adding new branch lines to the existing trunk line, without requiring restructuring of the entire harness. This dynamic design allows the system to evolve and accommodate new components as they are added to vehicle models.

Inventive Principle:

Principle #15Dynamics

5Adaptability or versatility

If the types and the number of components of wire harness to be manufactured increase due to a difference between vehicle models mounted with a wire harness or increases in types of optional electric components mounted on a vehicle, then customization for specific models is improved, but component cost or manufacturing cost increases

Engineering Contradiction:

Improvecustomization for vehicle modelsVSAvoidmanufacturing cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The wire harness is divided into a trunk line portion and multiple branch line portions. The trunk line contains a bundle of electric wires that are commonly used across different vehicle models, while each branch line contains electric wires specific to particular vehicle models or optional components.
