Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire routing devices for electric vehicles require cumbersome work to provide surplus length to voltage detection wires, leading to routing space inefficiencies and risks of crimping portion deformation.
Innovation Solution
A wire routing device with insulative material components, including wire housing parts with elongated grooves and terminal housing chambers, featuring wire surplus length absorption spaces and flexible wire lead-out parts that absorb surplus length variability without interfering with other wires, and prevent crimping portion deformation by using a round protrusion instead of a rigid surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wire fixing ribs are disposed on both sides of second hinges to fix electric wires, then electric wires can be prevented from being tightly stretched when hinges are expanded, but the work for providing surplus length to electric wires becomes troublesome and routing space increases
Solution Approach 1:
The patent extracts the wire fixing function from multiple distributed wire fixing ribs and relocates it to a single wire fixing rib positioned at the end of the housing groove. This eliminates the need for multiple fixing points and the troublesome work of providing surplus length at each point, while maintaining reliable wire tension control through the single strategically positioned fixing rib.
Solution Approach 2:
The patent positions the wire fixing rib at the end of the housing groove in the longitudinal direction, creating a one-dimensional linear fixing approach instead of a two-dimensional distributed fixing pattern. This dimensional simplification reduces routing complexity while maintaining effective wire control throughout the hinge expansion range.
2Reliability
If electric wires are sagged between wire fixing ribs in advance to prevent tight stretching, then wire tension is controlled, but routing space increases and wires may interfere with other components
Solution Approach 1:
The patent extracts the wire sagging requirement from the intermediate positions between multiple fixing ribs and concentrates the tension control function at the single wire fixing rib located at the groove end. This eliminates the need for distributed sagging and reduces the routing space occupied by sagged wire sections, while maintaining effective tension control.
3Reliability
If multiple wire fixing parts are used at given intervals, then electric wires can be secured during hinge expansion, but the routing process becomes more complex and time-consuming
Solution Approach 1:
The patent extracts the wire securing function from multiple interval-based fixing parts and consolidates it into a single wire fixing rib at the groove end. This single fixing point is sufficient to secure the wire during hinge expansion, eliminating the need for multiple fixing operations and significantly improving routing efficiency.
Solution Approach 2:
The patent merges the wire securing functions of multiple distributed fixing parts into a single integrated wire fixing rib structure. This consolidation maintains the reliability of wire securing during hinge expansion while reducing the number of operations required, thereby improving productivity.
4Ease of operation
If elongated housing grooves are used to route electric wires, then wires can be led from terminal housing chambers, but surplus length variability cannot be absorbed and routing space is inefficient
Solution Approach 1:
The patent incorporates a wire surplus length absorption space within the housing groove structure, preparing in advance for the variability of wire surplus length. This preliminary provision of absorption space allows efficient routing without requiring excessive routing space, as the absorption space is integrated into the groove design rather than requiring additional external space.

Function Achieved in This Case
Simplifies the routing process by eliminating the need for loosening electric wires, reduces routing space, and prevents crimping portion deformation by using flexible wires that abut against a round protrusion rather than a resin wall.

AI summary
A wire routing device includes a wire housing part, a terminal housing chamber part, and a plurality of wire lead-out parts. The terminal housing chamber part includes a plurality of terminal housing chambers. Each of the wire lead-out parts couples one of the housing grooves with one of the terminal housing chambers. Each of wire surplus length absorption spaces is formed inside of a substantially rectangle abcd defined by a section bc of an outer wall of the voltage detection wire housing part located at a side of the terminal housing chamber and a section ad of a wall of the housing groove which faces the section bc, which are cut by a line ab and a line cd.
