Wiring Harness Connector Layout for Configurable Bus Line Interruption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector devices for cable harnesses in electrical devices lack flexibility and efficiency in adapting to different variants and types of devices, particularly in connecting multiple electronic assemblies via a data bus like the CAN bus, limiting their universal application.
Innovation Solution
A plug connector device with N recesses for arranging wires, featuring IDC technology, a movable pin for line interruption, and a guide channel for termination elements, allowing for flexible configuration and termination of data bus lines, enabling efficient connection and disconnection of electronic assemblies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a standardized connector device is used for all device variants, then manufacturing efficiency is improved, but adaptability to different device configurations deteriorates
Solution Approach 1:
The connector device is divided into modular components: a base body with N recesses, a cover, and optional interruption units. This segmentation allows the same base connector design to be configured for different device variants by selectively adding or removing interruption units, thereby maintaining manufacturing efficiency while achieving adaptability.
Solution Approach 2:
The connector device incorporates movable interruption units that can be inserted or removed from the N recesses depending on the required configuration. This dynamic reconfigurability enables a single standardized connector design to adapt to different device variants, resolving the contradiction between standardization and customization.
2Adaptability or versatility
If multiple electronic components are connected via the wiring harness, then device functionality is improved, but connector complexity increases
Solution Approach 1:
The base body with N recesses is designed as a universal connector that can accommodate different numbers and types of electronic components. The same base structure supports various configurations by selectively populating recesses with interruption units, thereby providing multi-functionality without increasing fundamental connector complexity.
3Reliability
If the wiring harness is designed for specific device variants, then connection reliability is improved, but manufacturing flexibility deteriorates
Solution Approach 1:
The base connector device is pre-configured with N recesses designed to accommodate interruption units. This preliminary preparation allows for reliable connections while maintaining manufacturing flexibility, as the interruption units can be selectively added or removed during assembly based on the specific device variant requirements.
