Replaceable Connector for Vehicle Snow Control Wiring Harness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wiring harnesses for snow/ice control devices require significant labor and time to replace damaged connectors, as they need to be disconnected from the vehicle and resoldered, which can lead to improper connections and increased downtime.
Innovation Solution
A wiring harness assembly with a replaceable connector that can be easily and manually swapped out when damaged, featuring a fixed intermediate connector and a secure, accessible connection system that allows for quick replacement without removing the entire harness from the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional wiring harness connector is used, then the electrical connection between vehicle and snow/ice control device is established, but the connector becomes worn or damaged requiring significant labor and time for replacement
Solution Approach 1:
The connector is divided into two separate parts: a fixed connector attached to the wiring harness and a replaceable connector attached to the snow/ice control device. This segmentation allows the replaceable connector to be easily removed and replaced without affecting the fixed connector or requiring resoldering of individual wires, thus resolving the contradiction between durability and ease of repair.
Solution Approach 2:
The replaceable connector is designed to be discarded when worn or damaged and replaced with a new one. The fixed connector and wiring harness are recovered and retained for continued use. This approach eliminates the need to replace the entire wiring harness or resolder connections, significantly reducing repair time and labor while maintaining system reliability.
2Ease of repair
If a damaged connector is replaced by cutting and resoldering, then a new connector can be attached, but the process requires significant time and labor with potential for improper connections
Solution Approach 1:
By segmenting the connector into fixed and replaceable parts, the repair process is simplified to merely detaching and attaching connectors without any resoldering operations. This eliminates the time-consuming and error-prone resoldering process while ensuring proper connections through designed connector interfaces.
Solution Approach 2:
The replaceable connector is designed as a disposable component that can be easily replaced when worn or damaged. Instead of investing significant time and labor in resoldering operations, the system uses an inexpensive replaceable connector that can be quickly swapped out, reducing both time loss and potential for improper connections.
3Ease of repair
If the entire wiring harness is removed for connector replacement, then the damaged connector can be replaced, but the vehicle connection points must be disconnected and reconnected
Solution Approach 1:
The connector system is segmented into a fixed connector remaining at the vehicle wiring harness and a replaceable connector on the snow/ice control device. This allows replacement operations to be performed locally at the device end without disturbing the vehicle connection points, simplifying the repair procedure and reducing complexity.
Solution Approach 2:
The replaceable connector is extracted as a separate, independently replaceable component from the overall wiring harness system. This extraction allows the connector to be replaced without removing or disturbing the fixed connector and wiring harness, eliminating the need to disconnect and reconnect vehicle connection points and reducing procedural complexity.

AI summary
A first electrical wiring harness may be connectable to a vehicle and a second electrical wiring harness may be connectable to a snow/ice control device. A replaceable connector may be used between the first and second wiring harnesses so that it is easy to connect the wiring harnesses to each other and thereby electrically connect the snow/ice control device to the vehicle.
