Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional spray nozzle assemblies are used to direct atomized spray to multiple locations, then multiple spray guns are required, but this increases cost and device complexity
Solution Approach 1:
The spray system is segmented into three functional components: a single spray gun for atomization, a director fitting with multiple passages for flow distribution, and flexible hoses for positioning. This segmentation allows one spray gun to serve multiple locations through the director fitting's ability to direct flow to different passages.
Solution Approach 2:
The director fitting serves multiple functions: it receives pressurized liquid from the spray gun, distributes it to multiple passages, and works with flexible hoses to enable positioning at various locations. This multi-functionality eliminates the need for multiple spray guns, reducing both cost and complexity.
2Adaptability or versatility
If conventional spray nozzle assemblies are used, then spray can be directed to multiple locations, but this requires multiple units which increases cost
Solution Approach 1:
The director fitting merges multiple flow paths into a single distribution point, allowing one spray gun to supply multiple locations. This consolidation reduces the total number of components needed, lowering manufacturing costs while maintaining the ability to spray at multiple locations.
Solution Approach 2:
The director fitting acts as an intermediary between the spray gun and multiple discharge points. It receives liquid from the spray gun and distributes it through its passages to different locations via flexible hoses, eliminating the need to manufacture multiple spray guns.
3Adaptability or versatility
If spray nozzles are placed remote from the spray gun, then versatility is improved, but conventional systems require multiple guns which complicates the system
Solution Approach 1:
The system uses pressurized liquid flow through flexible hoses to transport atomized spray from the spray gun to remote locations. The hydraulic pressure enables the liquid to travel through the hoses and be discharged at distant points without requiring additional spray guns at each location.
Solution Approach 2:
The flexible hoses provide spatial flexibility, allowing the spray system to extend in multiple directions and reach remote locations. This adds a dimensional aspect to the system configuration, enabling versatile positioning without increasing the number of spray guns.
