Vehicle Cruise Control Sensor Cover with Indium NCVM Coating

Solution Overview

Problem

Conventional vehicle cruise control sensor-covers impede the aesthetic design of vehicle grills and hinder the continuity of grill designs, while also being non-abrasion and weather-resistant, and do not ensure electromagnetic transparency.

Innovation Solution

A vehicle cruise control sensor-cover with a metallic color and material, achieved through a non-conductive vacuum metallization method using indium or indium-containing alloys on a bottom cover member, combined with a transparent top cover member featuring a hard coating layer and selective laser etching, ensuring electromagnetic transparency and reducing manufacturing costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional cruise control sensor-cover is positioned in the grill of a vehicle, then the sensor is protected, but the continuity of grill design is impeded and aesthetic sense is hindered

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSShape

Solution Approach 1:

The sensor cover is designed with differentiated local qualities: the main body maintains a uniform color matching the grill, while only the logo area receives a metallic finish. This localized differentiation allows the cover to blend seamlessly with the grill design while still providing sensor protection and enabling logo identification.

Inventive Principle:
Principle #3Local quality

2Shape

If a metallic finish is applied to the sensor-cover, then aesthetic appeal is enhanced, but electromagnetic transparency is compromised

Engineering Contradiction:
Core Design Contradiction:
ShapeVSReliability

Solution Approach 1:

The metallic finish is applied locally only to the logo area rather than the entire sensor cover. This localized application provides the desired aesthetic appeal and brand identification while minimizing interference with the electromagnetic transparency required for sensor operation.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The sensor cover uses a composite structure combining a transparent or translucent base material with a metallic coating layer. This composite approach allows the cover to exhibit metallic aesthetic properties while maintaining sufficient electromagnetic transparency for the sensor to function effectively.

Inventive Principle:
Principle #40Composite materials

3Shape

If a three-dimensional emblem structure is created separately and assembled, then the three-dimensional effect is enhanced, but manufacturing complexity and cost increase

Engineering Contradiction:
Core Design Contradiction:
ShapeVSDevice complexity

Solution Approach 1:

The logo and the sensor cover body are merged into a single integrated component rather than being separate parts. The logo is formed as an integral part of the cover through molding or direct metallic deposition, eliminating the need for separate assembly operations and reducing manufacturing complexity while maintaining the three-dimensional visual effect.

Inventive Principle:
Principle #5Merging (Combining)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case
