Solution Overview
Problem
Modern vehicles with increasing electrical equipment face challenges in dissipating unwanted electrical currents, particularly in vehicles with body parts made of non-conductive materials, where conventional solutions like metal mesh are costly and complex to implement.
Innovation Solution
A bodywork element with a conductive surface made of electrically conductive material, such as a metal sheet, is extended between internal structural elements within a non-conductive lining, allowing for effective dissipation of unwanted electrical currents without the need for additional metal mesh during molding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If metal mesh is added when molding body parts to compensate for lack of electrical conductivity, then electrical current dissipation is improved, but manufacturing cost increases significantly
Solution Approach 1:
The conductive surface is extracted from the molding process and implemented as a separate component attached to the inner surface of the bodywork element. This allows the plastic body to maintain its non-conductive properties while the separate conductive surface provides the necessary electrical dissipation without requiring expensive metal mesh integration during molding
Solution Approach 2:
The solution combines non-conductive plastic material for the bodywork element with a separate conductive surface layer. This composite approach allows each material to perform its optimal function - the plastic provides structural integrity and shape, while the conductive surface provides electrical current dissipation - without the need for expensive metal mesh
2Reliability
If metal mesh is added when molding body parts to compensate for lack of electrical conductivity, then electrical current dissipation is improved, but manufacturing complexity increases
Solution Approach 1:
The conductive function is extracted as a separate attachable surface rather than being integrated into the molding process. This simplifies manufacturing by allowing the bodywork element to be produced as a standard plastic part, with the conductive surface added separately through attachment methods such as adhesives or mechanical fastening
Solution Approach 2:
The bodywork element is segmented into functional components: the main plastic body structure and the separate conductive surface layer. This segmentation allows each component to be manufactured independently using optimized processes, then assembled together, reducing overall manufacturing complexity compared to integrating metal mesh during molding
3Reliability
If conventional solutions with metal braids and conductive hinges are used, then electrical current dissipation is improved, but device complexity and cost increase
Solution Approach 1:
The conductive surface is merged with the inner surface of the bodywork element, creating an integrated appearance while maintaining functional separation. This eliminates the need for visible metal braids and conductive hinges, simplifying the overall structure while achieving the same electrical dissipation function
Solution Approach 2:
The conductive surface can be designed to match the appearance of the surrounding plastic body, making it visually indistinguishable. This aesthetic integration eliminates the need for visible conventional solutions like metal braids, reducing perceived structural complexity while maintaining electrical functionality
