Heat-Resistant Wiring Protector Assembly for Crowded Engine Bays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As vehicles downsize and engine compartments become more crowded with accessories and circuitry, there is a need to prevent heat-producing engine components from negatively affecting other elements by retaining electrical cables away from heated areas.
Innovation Solution
A wiring protector assembly made of heat-resistant materials, featuring a protector member and cover with defined cavities and snap-fitting structures, which securely holds electrical cables away from the exhaust manifold and other heated engine parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If electrical cables are positioned adjacent to the engine and exhaust manifold to save space in the downsized engine compartment, then the engine compartment can accommodate more accessories and circuitry, but the electrical cables are exposed to high temperatures that can cause warping, melting, or damage to the cables and surrounding components
Solution Approach 1:
A heat-resistant wiring protector assembly is introduced as an intermediary component between the electrical cables and the hot engine components. The protector includes a main body with a cavity that receives the electrical cable, and a cover that attaches to the main body, forming a protective barrier that isolates the cable from high temperatures while allowing the cable to be positioned in the crowded engine compartment
Solution Approach 2:
The patent changes the thermal resistance parameter by using heat-resistant materials for the wiring protector assembly. The material is specifically selected to have high heat resistance, allowing the assembly to withstand temperatures near the exhaust manifold without transmitting harmful heat to the electrical cable, thus enabling safe positioning in high-temperature zones
2Reliability
If electrical cables are routed away from heated engine portions to prevent damage, then cable integrity is maintained, but the engine compartment requires more space for cable routing and positioning
Solution Approach 1:
The wiring protector assembly serves as a mediator that allows electrical cables to remain in compact engine compartment positions while preventing direct contact with hot engine portions. The protective enclosure maintains cable integrity by blocking heat transfer, eliminating the need for lengthy cable routes away from heat sources
3Temperature
If the wiring protector assembly is made of heat-resistant material to withstand high temperatures near the exhaust manifold, then the assembly can protect cables in high-temperature zones, but the material selection and manufacturing process become more complex
Solution Approach 1:
The patent specifies that the wiring protector assembly be made of heat-resistant material capable of withstanding temperatures in the engine compartment near the exhaust manifold. This material parameter change enables the assembly to function in high-temperature zones, with the understanding that appropriate heat-resistant polymers or composites will be used in manufacturing
