Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a removable attachment is used to adjust the flow path cross-sectional area, then the adaptability of the hydraulic generator to different flow rates is improved, but the positional stability between the attachment and water turbine deteriorates
Solution Approach 1:
The flow path structure is divided into a first structure (fixed housing) and a second structure (removable attachment). The second structure can be detached and replaced to adjust the cross-sectional area of the flow path, enabling adaptation to different flow rates while maintaining a stable connection during operation.
Solution Approach 2:
A fixing portion is pre-formed on the second structure before installation. This fixing portion is designed to engage with the first structure to prevent positional changes between the attachment and water turbine during operation, ensuring stability while allowing easy removal and replacement when adjustment is needed.
2Ease of operation
If the attachment is removably attached to adjust water flow, then the ease of operation for flow rate adjustment is improved, but the reliability of electricity generation deteriorates due to positional changes
Solution Approach 1:
The flow path is segmented into removable second structures that can be easily detached and replaced by operators to adjust water flow characteristics, while each structure includes built-in fixing portions that ensure reliable positioning during operation.
Solution Approach 2:
The fixing portion acts as an intermediary element between the second structure and the first structure. It provides a reliable mechanical connection that prevents positional changes during operation, ensuring consistent electricity generation while still allowing easy removal when adjustment is required.
3Ease of repair
If the second structure is made removable for maintenance and adjustment, then the ease of repair is improved, but the manufacturing precision of the water passageway deteriorates due to assembly variations
Solution Approach 1:
The fixing portion is pre-formed on the second structure with precise dimensions and engagement features. This preliminary preparation ensures that when the second structure is installed in the first structure, the water passageway aligns precisely with the water turbine, maintaining manufacturing precision while enabling easy removal for maintenance.
Solution Approach 2:
The fixing portion serves as a precision intermediary that transfers and maintains the intended geometric relationship between the first structure and second structure. It compensates for assembly variations and ensures consistent water flow alignment, allowing the second structure to be removably attached while maintaining high manufacturing precision.
