Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If polymeric materials are used to achieve low permeability, then impermeability is improved, but bonding receptivity deteriorates
Solution Approach 1:
The invention divides the polymeric material into two distinct layers: a base layer providing impermeability and an adhesive layer providing bonding receptivity. This segmentation allows each layer to specialize in one function, resolving the contradiction between impermeability and bonding capability.
Solution Approach 2:
The invention creates a composite structure combining a polymeric base layer with an adhesive layer containing cationic polymer and adhesive agents. This composite material approach integrates materials with complementary properties to simultaneously achieve impermeability and bonding receptivity.
2Weight of moving object
If polymeric materials are used to achieve low density, then light weight is improved, but durability deteriorates
Solution Approach 1:
The composite structure combines a lightweight polymeric base layer with a durable adhesive layer. The base layer maintains low density for light weight, while the adhesive layer provides enhanced durability through its composition of cationic polymer and adhesive agents that resist degradation.
Solution Approach 2:
Different regions of the composite article have different properties optimized for their specific functions: the base layer has low density for light weight, while the adhesive layer has enhanced mechanical strength and durability for long-term performance.
3Ease of operation
If polymeric materials are used to achieve flexibility, then ease of operation is improved, but temperature resistance deteriorates
Solution Approach 1:
The composite structure assigns different thermal and mechanical properties to different layers: the base layer provides flexibility for ease of operation, while the adhesive layer provides temperature resistance through its cross-linked polymer structure and adhesive agents.
Solution Approach 2:
The combination of polymeric base material with adhesive layer creates a composite that exhibits both flexibility from the base layer and temperature resistance from the adhesive layer, resolving the contradiction between these two properties.
