Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electromagnetic shields for blocking unnecessary radio waves in collision avoidance systems are difficult to attach to other components effectively, lacking ease of attachment and potentially hindering the shielding performance.
Innovation Solution
An electromagnetic shield with a plate-shaped base and projecting portions, where the distance between the contact portion and the projecting portions is optimized to allow easy attachment and high shielding performance, utilizing a dielectric material and varying projection lengths to prevent interference with attachment while maintaining effective electromagnetic wave blocking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electromagnetic shield is designed with projecting portions to improve shielding performance, then the electromagnetic shielding capability is improved, but the ease of attachment to other components deteriorates
Solution Approach 1:
The electromagnetic shield employs different surface characteristics in different regions: the first surface has projecting portions for shielding, while the second surface has a flat contact portion for attachment. This local differentiation allows each region to optimize its function without compromising the other.
Solution Approach 2:
The shield structure is segmented into distinct functional zones: projecting portions on the first surface for electromagnetic wave blocking, and a flat contact portion on the second surface for attachment. This segmentation enables independent optimization of shielding and attachment functions.
2Reliability
If the projecting portions are made longer to improve shielding, then the electromagnetic wave blocking is improved, but the attachment process is hindered
Solution Approach 1:
The shield employs different surface characteristics in different regions: the first surface has projecting portions for shielding, while the second surface has a flat contact portion for attachment. This local differentiation allows each region to optimize its function without compromising the other.
Solution Approach 2:
The attachment function is extracted from the shielding surface by creating a separate flat contact portion on the second surface. This extraction allows the shielding structures (projecting portions) to be optimized for their primary function without interfering with the attachment process.

AI summary
An electromagnetic shield includes a plate-shaped base, a plurality of first projecting portions, and a contact portion. The base has a first surface and a second surface. The first surface is a surface configured to allow an electromagnetic wave to be incident on the first surface. The second surface is distant from the first surface. The plurality of first projecting portions project from the first surface in a direction away from the second surface. The electromagnetic shield is capable of being attached to a component such that the component is in contact with the contact portion and the first surface faces the component. A distance from the contact portion to the particular portion in a direction parallel to the first surface is equal to or shorter than a first distance d1 between the first projecting portion closest to the contact portion and the contact portion.
