Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a specialized liquid cleaning tool is used to clean the substrates, then the cleaning ability is improved, but the production process time increases and additional drying equipment is required
Solution Approach 1:
The patent replaces the liquid-based mechanical cleaning system with a pneumatic system using high-speed airflow generated by an air knife. This substitution eliminates the need for liquid cleaners and subsequent drying steps, directly resolving the time loss contradiction while maintaining cleaning effectiveness through aerodynamic forces.
Solution Approach 2:
The patent employs pneumatic principles by using an air knife to generate a high-velocity air stream that blows foreign matter off the substrate surface. This pneumatic cleaning method eliminates liquid-based cleaning requirements and associated drying time, directly addressing the production time issue while preserving cleaning capability.
2Manufacturing precision
If a specialized liquid cleaning tool is used to clean the substrates, then the cleaning ability is improved, but the cost increases
Solution Approach 1:
The patent replaces expensive liquid cleaning systems with a simpler pneumatic air knife system. This substitution reduces equipment costs by eliminating the need for liquid storage, delivery, and drying infrastructure, while maintaining effective foreign matter removal through high-velocity air flow.
Solution Approach 2:
The patent extracts and eliminates the unnecessary drying step from the cleaning process by using air blowing that inherently removes moisture along with foreign matter. This extraction of the drying requirement simplifies the overall system and reduces equipment costs.
3Manufacturing precision
If a specialized liquid cleaning tool is used to clean the substrates, then the cleaning ability is improved, but the cleaning process becomes cumbersome
Solution Approach 1:
The patent extracts and removes the drying step from the cleaning process by using high-velocity air blowing that simultaneously cleans and dries the substrate. This elimination of the separate drying operation simplifies the overall cleaning process and reduces operational complexity.
Solution Approach 2:
The patent merges the cleaning and drying functions into a single air blowing operation. The high-velocity air stream from the air knife performs both foreign matter removal and moisture evaporation in one step, thereby simplifying the process and reducing the number of required equipment components.
4Area of stationary object
If the ventilation ports are increased in number and the baffles are correspondingly disposed, then the cleaning range is expanded, but the device complexity increases
Solution Approach 1:
The patent divides the air knife structure into multiple segments with separate ventilation ports and baffles positioned at different locations. This segmentation allows the cleaning system to cover a larger substrate area by distributing air flow outlets strategically, while each segment remains a manageable modular unit that doesn't excessively increase overall complexity.
Solution Approach 2:
The patent extends the cleaning coverage by adding ventilation ports and baffles in multiple spatial dimensions rather than simply increasing size in one direction. This multi-dimensional arrangement expands the effective cleaning area while maintaining a compact overall structure, thereby managing device complexity.
