Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional metallic coating techniques (urethane resin paint or epoxy resin paint) are used, then the coating process is simple, but the feeling of vividness or hue of the coated surface is insufficient
Solution Approach 1:
The patent changes the chemical composition parameters of the coating material by using a metal complex of silver with amine as ligand instead of conventional urethane or epoxy resin paints. This parameter change enables the coating to exhibit superior vividness and hue while maintaining a simple coating process, resolving the contradiction between aesthetic quality and manufacturing simplicity.
2Illumination intensity
If sophisticated coating techniques (vacuum vaporization, CVD, PVD or spattering) are used, then rainbow coloring and feeling of hue are satisfied, but the apparatus required is large scale and the manufacturing technique required is of a high level
Solution Approach 1:
The patent replaces complex mechanical coating systems (vacuum vaporization, CVD, PVD, or spattering apparatus) with a simple liquid coating application method. By using a metal complex of silver with amine as ligand that can be applied as a liquid coating, the invention achieves rainbow coloring and superior hue without requiring large-scale or high-technology equipment, thus resolving the contradiction between aesthetic quality and device complexity.
3Ease of manufacture
If silver mirror reaction method is used, then sufficient ornamentation performance is achieved with relatively simple apparatus, but the product is inferior in mechanical strength and corrosion resistance
Solution Approach 1:
The patent creates a composite coating structure consisting of an inner coating layer and an outer coating layer with a silver thin film coating layer interposed between them. This composite structure combines the simplicity of the silver mirror reaction method with enhanced mechanical strength and corrosion resistance, as the silver layer is protected by the outer coating layer while the inner coating layer provides adhesion to the substrate, thus resolving the contradiction between manufacturing simplicity and structural strength.
4Illumination intensity
If conventional silver mirror coating process is used, then ornamentation is achieved, but the process involves multiple rinsing steps and requires special spraying means, causing complicated manufacturing process and large equipment expense
Solution Approach 1:
The patent extracts and eliminates the rinsing steps from the conventional silver mirror coating process. By using a metal complex of silver with amine as ligand that can be directly applied and dried without rinsing, the invention simplifies the manufacturing process and reduces equipment requirements while maintaining superior surface ornamentation in brightness, density, and smoothness, thus resolving the contradiction between aesthetic quality and process complexity.
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 a high-quality, corrosion-resistant, and aesthetically superior coating with improved mechanical strength and adherence, reducing the risk of delamination and exfoliation, while simplifying the manufacturing process and eliminating the need for expensive equipment.
Implementation Method 1
the silver face exhibits a face of high surface ornamentation in brightness, density, smoothness or the like compared with conventional metallic coating, because of melt bonding of deposited silver particles among themselves when heated.
Implementation Method 2
when a metal complex of silver with amine as ligand is painted on the inner coating layer, amine in the metal complex of silver reacts with resin having not reacted yet in the inner coating layer (silicon compound having isocyanate group or epoxy group). Further, when paint for the outer coating layer is coated on the silver thin film coating layer formed by painting a metal complex of silver, amine remaining in the silver thin film coating layer reacts with the resin forming the outer coating layer.
Implementation Method 3
silver deposited from the metal complex of silver is in a form of nanoparticle. Consequently, melt bonding of silver particles is accomplished swiftly and tight silver thin film coating layer is formed

AI summary
A surface ornament composition for fishing tackle or a bicycle is provided. An inner coating layer is laminated on a part made of fiber reinforced plastics, a silver thin film coating layer is laminated on the inner coating layer and an outer coating layer is laminated on the silver thin film coating layer. The inner and outer coating layers are formed by use of one selected from resin paint of two-part type formed by urethane reaction of isocyanate group and hydroxyl group, resin paint of two-part type formed by reaction of resin having amino group and silicon compound having epoxy group and resin paint of two-part or three part type in which the above two reactions are simultaneously generated. The silver thin film coating layer is formed of metal complex of silver with amine as ligand that is heated after having been applied.
