Connector Holder for Wire Harness Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing complexity of vehicle electrical systems due to advanced IT applications and diverse customer preferences leads to a higher number of wire harness types, complicating routing and maintenance, with optional sub-harnesses often having unstable connector arrangements.
Innovation Solution
A wire harness design featuring a connector holder that stabilizes and concentrates connectors by using rib-shaped engagement protrusions and slit-shaped engagement grooves, allowing connectors to be stacked and connected, enhancing visibility and maintainability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of optional sub-harnesses is increased to accommodate diverse customer preferences and IT applications, then the adaptability of the wire harness system is improved, but the routing complexity and difficulty of identifying desired sub-harnesses during maintenance increases
Solution Approach 1:
The wire harness system is divided into standard sub-harnesses and optional sub-harnesses as separate, identifiable units. Each optional sub-harness can be independently routed and maintained, allowing technicians to quickly locate and service specific functions without dealing with the entire harness system.
Solution Approach 2:
A connector holder is introduced as an intermediary component to organize and secure connectors. This mediator structure provides a standardized interface that simplifies the connection between sub-harnesses and makes routing more manageable despite the increased number of optional components.
2Adaptability or versatility
If optional sub-harnesses are added selectively to meet customer demands, then the versatility of the vehicle electrical system is improved, but the stability of connector arrangement deteriorates as connectors may hang in an unstable state
Solution Approach 1:
The connector holder is designed in advance with predetermined positions and structures to accommodate various connectors. By preparing the holding structure beforehand, connectors are immediately stabilized upon connection rather than being left in an unstable hanging state.
Solution Approach 2:
The connector holder acts as a mediator between the optional sub-harnesses and the main system, providing a stable intermediate structure that secures connectors in defined positions and prevents unstable arrangements.
3Adaptability or versatility
If multiple types of sub-harnesses are prepared in advance to cover all possible configurations, then the adaptability is improved, but the device complexity and difficulty of maintenance increases
Solution Approach 1:
The system segments functionality into standardized sub-harnesses with common connector types. This segmentation allows technicians to work with uniform components rather than unique configurations for each variant, significantly improving ease of repair and maintenance.
Solution Approach 2:
The connector holder is designed with universal characteristics that can accommodate multiple types of connectors through standardized holding mechanisms. This universality allows the same maintenance procedures to be applied across different sub-harness types, simplifying the repair process despite system diversity.
