Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple gas flow paths are provided to change spraying pattern, then spraying pattern adjustability is improved, but device complexity increases
Solution Approach 1:
The patent implements a movable blocking member that can dynamically switch between different positions to block or open flow paths. This allows the same nozzle structure to adapt between different spraying patterns (circular, linear, half-circle) without physical replacement, resolving the contradiction between adaptability and structural complexity
Solution Approach 2:
The patent designs a universal nozzle body that can produce multiple spraying patterns through a single structure by using a movable blocking member to control gas flow distribution. The same nozzle can generate different patterns by changing the blocking member's position, eliminating the need for multiple specialized nozzles and reducing overall system complexity
2Adaptability or versatility
If parts of ejection port are replaced to change spraying pattern, then spraying pattern flexibility is improved, but ease of operation deteriorates
Solution Approach 1:
The movable blocking member can be quickly repositioned between different blocking positions to change spraying patterns without requiring part replacement. This dynamic adjustment mechanism significantly improves ease of operation compared to traditional part replacement methods while maintaining pattern flexibility
3Adaptability or versatility
If multiple gas supply paths are connected to nozzle, then spraying pattern control capability is improved, but device complexity increases
Solution Approach 1:
The patent extracts the pattern control function from the gas supply system and transfers it to a movable blocking member within the nozzle. This separates the gas supply function (remained simple) from the pattern control function (achieved through blocking member positioning), reducing the complexity of the gas supply system while maintaining control capability
