Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a spray head includes a mechanism to adjust the irrigation area size, then the adaptability to different watering needs is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The spray head employs flexible nozzles made of elastic material that can dynamically change their orientation and bending angle in response to adjustment entity movement, enabling continuous variation of the irrigation area size without complex discrete mechanisms
Solution Approach 2:
The invention changes the physical state and orientation parameters of the nozzles by bending them through the adjustment entity, which modifies the spray pattern and irrigation area size by altering the nozzle geometry and angle rather than using multiple fixed-position nozzles
2Adaptability or versatility
If a spray head includes a mechanism to adjust the irrigation area size, then the versatility for various watering applications is improved, but the manufacturing cost increases
Solution Approach 1:
The nozzles are constructed from flexible elastic material that can be bent and deformed, eliminating the need for complex mechanical adjustment mechanisms and reducing manufacturing costs while maintaining versatility
Solution Approach 2:
The flexible nozzles self-adjust their orientation in response to the adjustment entity movement without requiring additional actuators or complex control mechanisms, simplifying the overall device and reducing manufacturing complexity
