Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual flipping and lowering operations are used for bags/cages, then the platform structure remains simple, but labor intensity and time consumption increase significantly
Solution Approach 1:
The patent applies pneumatic buoyancy adjustment systems with air bladders and compressed air tanks to enable automated lifting and lowering of aquaculture bags. This replaces manual labor with pneumatic actuation, allowing operators to control bag position remotely through air pressure regulation, thereby reducing labor intensity while adding pneumatic system complexity
Solution Approach 2:
The invention substitutes traditional mechanical winches and manual handling systems with a pneumatic buoyancy-based mechanical system. The air-filled bladders provide lift through buoyancy forces, eliminating the need for complex mechanical lifting apparatus and reducing operational complexity despite introducing pneumatic components
2Ease of operation
If bags/cages are placed in shallow waters during growing season, then access for maintenance is improved, but vulnerability to storm damage increases
Solution Approach 1:
The patent implements dynamic depth adjustment capability where bags can be moved between shallow and deep water positions using pneumatic buoyancy control. This allows the system to adapt to changing conditions - maintaining shallow positions for easy maintenance during calm periods and relocating to deeper waters during storm threats, thereby resolving the contradiction between maintenance accessibility and storm resistance
Solution Approach 2:
The invention changes the operational parameter of water depth dynamically. By controlling the air pressure in buoyancy bladders, the system can adjust the effective depth position of aquaculture bags, enabling transition from shallow water (easy access) to deep water (storm protection) based on environmental conditions
3Force
If mechanical equipment such as winches is used to raise bags/cages, then lifting capability is improved, but labor intensity and time consumption remain high
Solution Approach 1:
The patent uses pneumatic air bladders filled with compressed air to generate lifting forces. This pneumatic system provides sufficient lifting capability to raise heavy aquaculture bags while operating much faster than manual methods, reducing time consumption significantly compared to traditional winch systems that require gradual mechanical lifting
Solution Approach 2:
The invention changes the physical state of the lifting medium from mechanical (winch cables) to pneumatic (compressed air in bladders). This parameter change enables rapid volume expansion and contraction of the bladders, providing quick lift and lower operations that reduce time consumption while maintaining adequate lifting force
