Wiring Harness Assembly with Joint Connector for ECU Standardization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wiring harness systems for vehicles require a large number of electrical wires and increased manufacturing costs due to the need for specific electrical connections for each electronic device, making standardization of the electronic control unit (ECU) difficult when option devices are added or changed.
Innovation Solution
A wiring harness assembly where a joint connector is connected to both standard and option wiring harnesses, allowing for standardized control signals to be transmitted from the ECU, reducing the number of electrical wires needed and enabling the ECU to remain standardized regardless of the combination of electronic devices mounted in the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate wiring harnesses are provided for standard and option electronic devices, then each device can be independently controlled, but the number of electrical wires increases and ECU standardization becomes difficult
Solution Approach 1:
The patent combines multiple wiring harnesses (standard wiring harness and option wiring harness) into a single integrated wiring harness assembly. The joint connector merges the connection functions, allowing both standard and option electronic devices to be connected through a unified structure with shared signal wires, thereby reducing the total number of wires while maintaining adaptability to different device combinations.
Solution Approach 2:
The joint connector is designed with universal functionality to handle both standard and option electronic devices through a single interface. It incorporates multiple connection terminals that can accommodate different device types, enabling the same wiring harness assembly to serve multiple purposes and support various electronic device configurations without requiring separate dedicated wiring for each device type.
