Polysurface Electric Heating Film Spacing for Lampshade Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric heating films on car headlight lampshades are difficult to adhere securely due to the curved surface, leading to manufacturing complexities, high costs, and frequent wire bending or breaking, which results in heat failure.
Innovation Solution
A method of configuring a polysurface object by spacing the heat unit of the electric heating film from the connection face and adhering it to the inner fence of the lampshade, maintaining a consistent distance to prevent bending and fracture, and ensuring effective heat distribution without contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electric heating film is adhered directly on the curved inner wall of the lampshade, then the heating function is achieved, but the heating wires are bent and broken causing heat failure
Solution Approach 1:
The patent introduces a heat-conducting plate as an intermediary component between the heating wires and the curved lampshade surface. The plate is spaced apart from the connection face by a distance that maintains flatness, allowing the heating wires to be mounted on a flat surface without bending, while still effectively conducting heat to the lampshade through the plate structure.
2Reliability
If the electric heating film is plated on the inner wall of the lampshade, then secure adhesion is achieved, but the manufacturing process becomes complicated and costly
Solution Approach 1:
The patent extracts the heating function from the curved surface constraint by introducing a separate heat-conducting plate structure. This plate can be manufactured independently with a flat mounting surface, simplifying the manufacturing process while maintaining secure adhesion to the lampshade through the spaced-apart configuration.
3Strength
If the heat unit is spaced a distance from the connection face, then the flatness of the heat unit is maintained preventing wire bending, but the heat distribution efficiency may be reduced
Solution Approach 1:
The patent resolves the heat distribution issue by transitioning from direct surface contact to a spaced-apart three-dimensional configuration. The heat-conducting plate is positioned at a specific distance from the connection face, creating a controlled thermal field that maintains wire integrity while ensuring effective heat transfer through the plate's thermal conduction properties.

AI summary
A method of configuring a polysurface object contains: connecting a peripheral area of an electric heating film with a connection face of the polysurface object via a fixing unit. A heat unit of the electric heating film is spaced a distance from the connection face. Thereby, water mists forming on the inner fence of the lampshade or melting snows on the lampshade is avoidable. Preferably, the distance is not changeable based on the change of the curvature of the lampshade in the single curvature change or the multiple curvature changes to maintain a flatness of the heat unit, thus prevent bending and fracture of the multiple heating wires and an electric heat failure.
