Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metal filter housing is used, then crash stability is improved, but manufacturing cost increases due to laborious soldering or welding
Solution Approach 1:
The patent combines metal filter housing with plastic components (nozzles, seals, heating element housing) to create a composite structure. The metal housing provides crash stability while the plastic components eliminate the need for complex soldering or welding operations, reducing manufacturing cost and complexity.
Solution Approach 2:
The patent merges multiple functions into integrated components: the plastic component combines nozzle, seal, and heating element housing into a single unit that is inserted as one piece into the metal filter housing, eliminating separate assembly steps for sealing and mounting.
2Stability of the object's composition
If metal filter housing with through-openings is used, then structural stability is maintained, but connection complexity increases due to soldering or welding requirements
Solution Approach 1:
The patent replaces permanent metal connections (soldering/welding) with removable plastic components that can be easily inserted and removed. The plastic nozzles and seals are designed as disposable or replaceable units that simplify connection and disconnection operations.
Solution Approach 2:
The plastic component acts as an intermediary between the metal filter housing and the external piping system. It provides sealing and connection functions without requiring direct metal-to-metal joining, thereby reducing connection complexity while maintaining structural integrity.
3Ease of operation
If plastic component with heating element is inserted through perforated mask, then assembly simplicity is improved, but sealing complexity must be managed
Solution Approach 1:
The patent combines the seal with the plastic component housing into an integrated unit. The seal is molded as part of the plastic component, eliminating separate sealing operations and simplifying assembly while ensuring proper sealing through the perforated mask.
Solution Approach 2:
The patent uses homogeneous plastic material for the component housing and seal, ensuring consistent sealing properties and simplifying manufacturing. The uniform material composition provides reliable sealing performance across the entire plastic component.
