Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for producing heating elements, such as seat and armrest heaters in vehicles, are not highly automated, making them complex to manufacture and assemble efficiently.
Innovation Solution
A material web comprising a conductive layer, a cover layer, and a separating strip with an anti-stick coating is used, allowing for easy separation and exposure of the conductive layer for subsequent electrode lamination and contacting, featuring a heating element with electrodes and a non-stick coated separating strip between the conductive and cover layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If electrodes are sewn together with insulating material, then heating elements can be manufactured, but the manufacturing process is not highly automated and is complex
Solution Approach 1:
The patent divides the heating element into distinct functional layers: conductive layers with electrodes, insulating layers, and cover layers. This segmentation allows each layer to be manufactured and prepared separately, then combined through automated lamination processes, thereby increasing automation while managing complexity through modular construction
Solution Approach 2:
The patent employs composite material structures combining conductive materials (for heating), insulating materials (for safety), and cover materials (for protection). These composite layers are bonded through automated lamination processes, enabling high-volume automated manufacturing while maintaining functional complexity through material composition rather than mechanical assembly
2Ease of manufacture
If multiple layers are sewn together at once, then conductive suture material is arranged on the surface, but the process remains complex and difficult to automate
Solution Approach 1:
The patent prepares each layer with its functional elements (electrodes, conductive materials, insulating properties) before assembly. Conductive layers are pre-equipped with electrodes, insulating layers are pre-positioned, and cover layers are pre-prepared. This preliminary preparation of individual layers enables automated lamination processes to simply bond pre-configured components together, simplifying the overall manufacturing process while achieving high automation
Solution Approach 2:
The patent introduces insulating layers and separating strips as intermediary elements between conductive layers and cover layers. These intermediaries facilitate automated assembly by providing standardized bonding surfaces for lamination, enabling machines to process multiple layers simultaneously without complex positioning requirements, thus improving ease of manufacture and automation capability
