Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for forming metallic texture decorative parts on home appliance components fail to efficiently apply the decorative part only on partial regions with complex shapes, leading to material wastage and high costs.
Innovation Solution
A component for home appliances with a decorative part formed on a partial region having a bent three-dimensional shape, using a hot stamping process to transfer a decorative film, ensuring continuous formation without overlapping steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If wet plating method is used to form decorative part on component surface, then metallic texture and high hardness are achieved, but material consumption increases and cost rises
Solution Approach 1:
The patent applies decorative parts only to specific local regions of the component surface where aesthetic enhancement is needed, rather than plating the entire surface. This selective application reduces material consumption while maintaining the metallic texture and hardness benefits in the decorative regions.
2Shape
If wet plating method is used to form decorative part, then metallic texture is achieved, but decorative part cannot be formed only on partial region of component
Solution Approach 1:
The component surface is divided into decorative regions and non-decorative regions. The decorative part is segmented and applied only to the specific partial regions requiring aesthetic enhancement, allowing precise control over where the metallic texture appears while simplifying the manufacturing process for selective decoration.
3Ease of manufacture
If conventional dry coating method is used to form decorative part on bent surface, then decorative part can be applied, but coating fails to be smooth and overlapping portions occur
Solution Approach 1:
The patent modifies the application parameters and methodology for depositing the decorative part on bent surfaces. By adjusting factors such as application pressure, material viscosity, and deposition technique, the decorative part achieves smooth coating on complex three-dimensional surfaces without overlapping, even on bent and geometrically intricate regions.
