Illuminated Vehicle Logo Cover With Scratch-Resistant Inner Coating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle logo assemblies are not cost-effective and lack sufficient scratch resistance, which affects their durability and visibility.
Innovation Solution
A vehicle logo assembly with a housing and cover that accommodates a light-emitting assembly and a light-diffusing assembly, featuring a coating on the inner side of the cover for protection and scratch resistance, comprising multiple sub-coatings and a light-transmitting portion, and a method using in-mold film insert injection molding for production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a coating is applied on the outer side of the cover to form the vehicle logo, then the logo visibility is improved, but the coating is prone to scratching and peeling
Solution Approach 1:
The patent applies the logo coating on the inner side of the cover instead of the outer side. This inverted approach protects the coating from direct exposure to external scratching forces while still allowing the logo to be visible through the translucent cover material. The coating is positioned between the light source and the outer surface, reversing the conventional application method.
Solution Approach 2:
The translucent cover material serves as an intermediary between the coated logo surface and the external environment. It transmits light from the illuminated logo while simultaneously protecting the delicate coating layer from direct contact with external objects that could cause scratching or peeling.
2Reliability
If multiple sub-coatings are applied to enhance scratch resistance, then the coating protection is improved, but the manufacturing complexity increases
Solution Approach 1:
The coating system is divided into multiple functional sub-coatings: a base coating layer for adhesion and a translucent protective topcoat for scratch resistance. This segmentation allows each layer to perform its specific function optimally while maintaining a manageable manufacturing process.
Solution Approach 2:
The patent uses composite coating structures combining different material properties - an opaque or translucent base layer for logo formation and a translucent protective topcoat for durability. This composite approach enhances scratch resistance while maintaining the visual appearance and light transmission properties needed for logo visibility.
3Reliability
If the cover thickness is increased to protect the coating, then the coating protection is improved, but the light transmission efficiency decreases
Solution Approach 1:
The patent optimizes the cover thickness parameter to achieve a balance between protection and light transmission. Rather than simply increasing thickness, the design specifies a controlled thickness range that provides sufficient mechanical protection for the coating while maintaining adequate translucency for effective light transmission and logo visibility.
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
The solution provides excellent scratch resistance and cost-effective production while enhancing visibility through the use of multiple sub-coatings and a light-transmitting portion, allowing light to exit and ensuring the logo remains protected and easily visible.
