Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional components are used to achieve desired aesthetic appearance, then the product appearance is improved, but sustainability and formulation stability deteriorate
Solution Approach 1:
The patent changes the chemical parameters by replacing traditional styrene acrylate copolymer with a combination of non-ionic opacifier and ionic polymer. This parameter substitution maintains the desired aesthetic appearance (opacification) while improving formulation stability and sustainability, resolving the contradiction between appearance and stability
Solution Approach 2:
The patent employs a composite stabilizing system combining two different polymer types (non-ionic and ionic) that work synergistically. This composite approach provides both the aesthetic opacification properties and the formulation stability, eliminating the need for unsustainable traditional components
2Object-affected harmful factors
If components are removed to improve sustainability, then environmental friendliness is improved, but formulation stability deteriorates
Solution Approach 1:
The patent extracts and removes unsustainable components (styrene acrylate copolymer) from the formulation while replacing them with sustainable alternatives (non-ionic opacifier and ionic polymer). This extraction maintains sustainability improvements while the carefully selected replacement components preserve formulation stability
Solution Approach 2:
The patent introduces intermediary stabilizing components that mediate between the requirement for sustainability and the need for stability. The non-ionic opacifier and ionic polymer act as intermediaries that provide both sustainability and the necessary formulation stability, bridging the gap between these two requirements
3Use of energy by moving object
If ambient temperature processing is used to improve energy efficiency, then energy consumption is reduced, but product stability deteriorates
Solution Approach 1:
The patent changes the thermal parameters by enabling processing at ambient temperatures rather than requiring elevated temperatures. The selected polymer components are specifically chosen for their ability to provide stable formulations under mild thermal conditions, thus reducing energy consumption while maintaining product stability
Solution Approach 2:
The stabilizing system components are selected to be self-stabilizing at ambient temperatures, requiring no external energy input for stabilization. The non-ionic opacifier and ionic polymer naturally maintain formulation stability under ambient conditions, eliminating the need for energy-intensive processing or stabilization steps
