Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If a moisture barrier is permanently applied to provide long-term protection, then protection duration is improved, but removability deteriorates
Solution Approach 1:
The moisture barrier transitions from a static permanent state to a dynamic removable state. The composition is designed to cure forming a protective barrier that can be intentionally removed after serving its protective function, allowing the system to adapt between protection and removal based on needs.
Solution Approach 2:
The composition utilizes chemical parameters changes through selective curing agents that control the curing process. By adjusting chemical parameters such as curing agent type, concentration, and activation conditions, the barrier achieves both durable protection during service and controlled removability when needed.
2Ease of operation
If a temporary moisture barrier is applied to protect against one-time events, then removability is improved, but robustness deteriorates
Solution Approach 1:
The composition employs parameter changes through controlled curing mechanisms. The barrier achieves robustness through proper curing to form a strong protective layer, while removability is enabled by controlling the curing parameters and composition design to allow intentional removal without compromising the barrier's strength during service.
Solution Approach 2:
The moisture barrier uses composite material design combining polymer resins with specific curing agents. This composite approach creates a barrier that derives robustness from the cured polymer network while incorporating elements that enable controlled removal, such as specific resin-curing agent combinations that balance strength and detachability.
3Ease of manufacture
If a one-part composition is used to simplify application, then ease of manufacture is improved, but curing complexity deteriorates
Solution Approach 1:
The composition merges the resin and curing agent into a single unified composition that remains stable during storage and transport. The curing agent is incorporated in a dormant or protected state within the one-part formulation, activating only upon application to the substrate, thus simplifying application while managing curing complexity internally.
Solution Approach 2:
The composition performs preliminary preparation by pre-mixing resin and curing agent in the correct proportions during manufacturing. This preliminary action eliminates the need for on-site mixing, simplifying application procedures while the curing complexity is managed through controlled activation mechanisms built into the formulation.
