Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle cables require complex and space-consuming configurations for multiple wires, leading to difficulties in securement and water resistance, especially in compact areas like tire houses, and lack sufficient bending resistance.
Innovation Solution
A multi-core cable design featuring two power wires, two twisted pairs of signal and electric wires, all stranded together with a sheath, which allows for balanced arrangement and reduced space requirements, enhancing water resistance and bending durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If multiple separate cables are used for power and signal wires, then each wire can be independently managed, but the cable configuration becomes complex and consumes more space
Solution Approach 1:
The patent combines multiple separate cables (power cables and signal cables) into a single integrated multi-core cable assembly. This merging approach consolidates what would otherwise be separate cable management tasks into one unified structure, reducing overall complexity while maintaining organized internal wiring with dedicated channels for power and signal transmission.
2Ease of operation
If multiple separate cables are used, then installation flexibility is maintained, but securement becomes difficult in compact areas
Solution Approach 1:
By integrating power wires and signal wires into a single multi-core cable, the patent creates one manageable unit that is easier to secure and route through compact vehicle spaces compared to managing multiple separate cables. The unified structure allows for single-point attachment and routing decisions.
Solution Approach 2:
Within the integrated cable, the patent segments power wires and signal wires into distinct groups or channels, allowing them to be organized and accessed independently while maintaining the benefits of integration. This internal segmentation provides functional organization without requiring separate external cable management.
3Reliability
If separate cable configurations are used for power and signal wires, then functional organization is achieved, but water resistance is compromised
Solution Approach 1:
The patent achieves superior water resistance by integrating all wires into a single cable assembly that can be sealed as one unit. The outer sheath and internal structure are designed to prevent water ingress across the entire assembly, creating a unified waterproof barrier that is more effective than attempting to seal multiple separate cables individually.
4Strength
If non-stranded configuration is used, then manufacturing is simpler, but bending resistance is insufficient
Solution Approach 1:
The patent changes the structural parameter of the wires from solid to stranded configuration. This parameter change significantly improves bending resistance and flexibility, allowing the cable to withstand repeated flexing and installation stresses. The stranded construction enables the cable to bend without cracking while maintaining electrical conductivity.
