Solution Overview

Problem

Radar covers with decorations applied to the inner wall surfaces of recesses on the back surface of transparent members often suffer from a poor stereoscopic effect due to thickness restrictions and limitations in visual recognition, especially with paint that changes color depending on the viewing direction, which impairs the three-dimensional appearance of emblems and patterns.

Innovation Solution

The radar cover design features a transparent member with extension recesses on its back surface, having a first and second connection surface and an intermediate surface with a main design surface oriented differently, and a protrusion with a colored layer on its distal end surface, enhancing the stereoscopic effect by varying the visual recognition angles and creating a brighter or darker appearance when viewed from outside.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a paint layer is applied to the inner wall surface of a recess on the back surface of the transparent member, then the decoration can be formed inside the radar cover, but the stereoscopic effect is poor due to thickness restrictions and limited visual recognition angles

Engineering Contradiction:
Improvedecoration formationVSAvoidstereoscopic effect
Core Design Contradiction:
Ease of manufactureVSShape

Solution Approach 1:

The patent transitions from a two-dimensional flat recess to a three-dimensional extension recess with multiple surfaces (first connection surface, second connection surface, and intermediate surface). This dimensional change allows light to reflect from multiple angles, creating a stereoscopic effect while maintaining the decoration inside the radar cover.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The extension recess is divided into multiple distinct surfaces (first connection surface, second connection surface, intermediate surface) rather than a single flat surface. This segmentation allows different portions of the paint layer to be viewed from different angles, enhancing the three-dimensional appearance.

Inventive Principle:
Principle #1Segmentation

2Loss of information

If a colored layer is formed on the bottom surface of the recess to superimpose characters or patterns, then the characters can be formed, but the stereoscopic effect of the emblem is impaired because the character appears planar

Engineering Contradiction:
Improvecharacter formationVSAvoidstereoscopic effect of emblem
Core Design Contradiction:
Loss of informationVSShape

Solution Approach 1:

The patent applies the colored layer specifically on the intermediate surface rather than the entire bottom surface of the recess. This localized application allows the character to be formed while the first and second connection surfaces remain to provide the stereoscopic effect, creating different visual qualities in different regions.

Inventive Principle:
Principle #3Local quality

AI summary

A radar cover includes, a transparent member which has an extension recess recessed toward a front surface side from the back surface, extending along the back surface, and having a paint layer formed on an inner wall surface thereof. The inner wall surface of the extension recess has, a first connection surface disposed on a first side in an orthogonal cross section with respect to an extension direction of the extension recess and connected to the back surface, a second connection surface disposed on a second side in the orthogonal cross section and connected to the back surface, and an intermediate surface connected to each of the first connection surface and the second connection surface and having a main design surface disposed such that a direction in which the main design surface is oriented is different from each of the first connection surface and the second connection surface.
