Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sensor covers for millimeter wave and infrared sensors lack aesthetic appeal and do not transmit electromagnetic waves effectively, particularly when given a metallic appearance, limiting their functionality and design possibilities.
Innovation Solution
A sensor cover comprising a substrate with a silver particle layer that includes a silver particle with an electromagnetic wave transmission layer on its surface, which is an organic layer, allowing for excellent metallic luster and electromagnetic wave transmittance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a metal plating layer is applied to give a metallic appearance, then aesthetic appeal is improved, but electromagnetic wave transmission deteriorates
Solution Approach 1:
The invention applies a thin metal plating layer (5-50 nm thickness) that provides metallic appearance locally while maintaining electromagnetic wave transmission capability. The localized thin coating allows aesthetic improvement without completely blocking the electromagnetic waves needed for sensor function.
Solution Approach 2:
The invention changes the thickness parameter of the metal plating layer to an optimal range (5-50 nm) that balances aesthetic appearance and electromagnetic wave transmission. By controlling the thickness parameter, both metallic luster and sensor functionality are achieved simultaneously.
2Reliability
If conventional plastic plates are used for sensor covers, then electromagnetic wave transmission is maintained, but aesthetic appeal deteriorates
Solution Approach 1:
The invention creates a composite structure by applying a metal plating layer on top of a plastic substrate. This composite material combines the electromagnetic wave transmission properties of plastic with the aesthetic metallic appearance of the thin metal coating, resolving the contradiction between functionality and appearance.
3Reliability
If indium vapor deposition film is used to replace metal plating, then electromagnetic wave transmission is improved, but metallic appearance deteriorates
Solution Approach 1:
The invention changes the material parameter from indium vapor deposition to a thin metal plating layer with optimized thickness (5-50 nm). This parameter change maintains electromagnetic wave transmission while significantly improving the metallic appearance and aesthetic quality of the sensor cover.
