Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If carbon black is used to color dark textiles or engineering plastics, then the shading and dirt avoidance are improved, but the infrared light absorption increases causing rapid temperature rise
Solution Approach 1:
The patent changes the chemical composition parameters of the pigment from carbon black to a specific multi-component organic pigment system (Pigment Yellow 147, Pigment Red 144, Pigment Blue 60, and Pigment Black 26). This parameter change in the pigment composition fundamentally alters the infrared absorption characteristics while maintaining the dark color appearance, thereby reducing temperature rise under infrared exposure.
Solution Approach 2:
The patent employs a composite pigment system combining four different organic pigments in specific proportions (Yellow 147: 10-30 parts, Red 144: 10-30 parts, Blue 60: 5-20 parts, Black 26: 20-40 parts). This composite approach creates a synergistic effect where the combination of pigments achieves both the desired dark coloration and reduced infrared absorption compared to using carbon black alone.
2Manufacturing precision
If conventional pigment compositions are used, then the coloring is achieved, but the original colors are not maintained after heating at 285-300°C causing processing complexity increase
Solution Approach 1:
The patent performs preliminary color stabilization by formulating a heat-resistant organic pigment composition that maintains its color properties at processing temperatures of 285-300°C. The specific selection and proportioning of pigments (Yellow 147, Red 144, Blue 60, Black 26) are designed to resist degradation during the extrusion and molding processes, thereby maintaining color consistency without requiring additional post-processing steps.
Solution Approach 2:
The patent replaces expensive and problematic carbon black with a cost-effective organic pigment system that provides both coloring and heat stability. The organic pigments are selected to be economically viable while eliminating the need for additional dyeing processes, thereby reducing overall processing complexity and cost.
3Manufacturing precision
If carbon black is used for coloring, then the dark color is achieved, but wastewater pollution is increased due to additional dyeing processes
Solution Approach 1:
The patent extracts and eliminates the need for separate dyeing processes by incorporating all necessary coloring functions into the masterbatch formulation itself. The multi-component organic pigment system (Yellow 147, Red 144, Blue 60, Black 26) provides complete coloration capability, removing the requirement for additional aqueous dyeing steps that generate wastewater pollution.
Solution Approach 2:
The organic pigment composition performs multiple functions simultaneously: it provides dark coloration, maintains color stability during high-temperature processing (285-300°C), and eliminates the need for separate dyeing operations. This multi-functional pigment system replaces both carbon black's coloring function and the subsequent dyeing process, thereby preventing wastewater generation.
