Indium Film Vehicle Badge for Radar-Compatible Front-End Styling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of radar systems in vehicles poses challenges in terms of badge placement and styling, as traditional badges can interfere with radar functionality and limit design flexibility due to their fixed locations and materials.
Innovation Solution
A radar-compatible badge is created by thermally forming an indium film into a desired shape, molding a plastic back layer, and adding a colored plastic front layer, allowing for flexible placement and reduced interference with radar systems while maintaining aesthetic appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional badge is placed on the front of the vehicle, then the vehicle styling is complete and manufacturer identification is provided, but the radar system functionality is interfered with and design flexibility is limited
Solution Approach 1:
The badge material is changed from traditional metallic or plastic compositions to an indium-based material that is transparent to radar frequencies. This parameter change in material composition allows the badge to maintain its visual function while becoming transparent to radar waves, thereby resolving the contradiction between radar functionality and badge placement flexibility
Solution Approach 2:
The invention uses a composite structure consisting of an indium film layer combined with transparent substrates. This composite material approach creates a badge that visually identifies the vehicle while simultaneously allowing radar waves to pass through, thus maintaining both radar system reliability and badge placement adaptability
2Shape
If the badge is made from traditional materials, then the visual appearance is achieved, but the radar beam distortion occurs
Solution Approach 1:
The material composition parameter is changed from traditional opaque materials to indium-based transparent materials. This parameter change enables the badge to maintain its visual shape and appearance while allowing radar waves to pass through undistorted, eliminating the harmful radar beam distortion effect
Solution Approach 2:
The indium film acts as an intermediary material between the visual identification function and the radar wave transmission function. It provides the necessary visual appearance for the badge while simultaneously serving as a transparent medium for radar waves, thus resolving the contradiction between visual appearance and radar beam integrity
3Ease of manufacture
If the badge location is fixed, then the manufacturing process is simplified, but the styling flexibility and radar integration are reduced
Solution Approach 1:
The indium-based badge material provides universal applicability across different vehicle designs and radar configurations. The material's radar transparency property allows the same badge design to be placed in multiple locations without interfering with radar systems, thus achieving both manufacturing simplicity and styling flexibility through multi-functionality

AI summary
A method of forming a badge may include thermally forming an indium film into a desired shape for the badge, including thermally forming a raised symbol above a front surface on the front side of the indium film; molding a plastic back layer to a back side of the thermally formed indium film; and molding a plastic front layer to a front side, opposite to the back side, of the thermally formed indium film. The badge may be mounted on a front of a vehicle.
