Solution Overview

Problem

Automobile wiring systems face challenges in accommodating various specifications with a smaller number of circuits, as different mounted systems or apparatuses require distinct configurations, leading to complexity and inefficiency.

Innovation Solution

A wiring system incorporating a multipurpose wiring member with a multipurpose circuit and connector, along with first and second purpose wiring members and connectors, allows for flexible connection to different electrical components, enabling the same multipurpose circuit to serve both types of components by switching connectors, thus reducing the overall number of circuits needed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate wiring members are provided for different electrical components, then connection reliability is improved, but the number of circuits increases and adaptability decreases

Engineering Contradiction:
Improveconnection reliabilityVSAvoidadaptability to different specifications
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent applies universality by designing a wiring member that can serve multiple functions through connector interchangeability. The multipurpose wiring member includes a connector that can be replaced with different connectors to accommodate different electrical components, allowing a single wiring member design to adapt to various specifications while maintaining reliable connections for each specific application

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple wiring members are used for different specifications, then adaptability is improved, but device complexity increases

Engineering Contradiction:
Improveability to handle multiple specificationsVSAvoidnumber of circuits
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent reduces device complexity by using a universal wiring member design that can accommodate multiple specifications. Instead of creating separate wiring members for each specification, the invention uses a single multipurpose wiring member with interchangeable connectors, thereby reducing the overall number of circuits and simplifying the system while maintaining the ability to handle various specifications

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent applies segmentation by separating the connector from the wiring member body. This allows the connector to be independently replaced or modified without changing the main wiring member structure. The wiring member is divided into a universal body portion and a replaceable connector portion, enabling flexibility in adapting to different specifications while keeping the core wiring system simple and standardized

Inventive Principle:
Principle #1Segmentation

AI summary

A wiring system is a wiring system including a multipurpose wiring member including at least one multipurpose circuit and a multipurpose connector to which the multipurpose circuit is connected, the wiring system further exclusively including: a first purpose wiring member including a first purpose circuit and a first purpose connector to which the first purpose circuit is connected, and a second purpose wiring member including a second purpose circuit and a second purpose connector to which the second purpose circuit is connected. When the first purpose connector is connected to the multipurpose connector, the multipurpose circuit is connected to the first purpose circuit, and when the second purpose connector is connected to the multipurpose connector, the multipurpose circuit is connected to the second purpose circuit.
