Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a steel pipe construction is used to couple the tubular container to the vessel, then the device can be positioned properly relative to the underwater bottom, but the device complexity increases and flexibility is reduced
Solution Approach 1:
The patent removes the steel pipe construction from the device system. Instead of using a rigid coupling structure, the invention allows the tubular container to be freely coupled to the vessel, extracting the complex positioning mechanism while maintaining the essential function of water injection for bottom material displacement.
Solution Approach 2:
The invention enables the device to be coupled to any type of vessel (pleasure craft, fishing boat, workboat, etc.) rather than requiring specialized vessels. This universal coupling approach eliminates the need for complex vessel-specific positioning systems, allowing the same device to operate on diverse vessel types.
2Use of energy by moving object
If water is injected into the bottom layer to reduce density and enable flow, then bottom material can be displaced with relatively little energy, but the device can only be applied on vessels built or converted for this purpose
Solution Approach 1:
The device is designed to be coupled to any type of vessel including pleasure crafts, fishing boats, workboats, and multihulls. The simplified coupling mechanism without steel pipe construction allows universal application across different vessel types, eliminating the need for specialized vessel conversions while maintaining the low-energy water injection method for bottom material displacement.
3Stability of the object's composition
If suction means are placed under water to stabilize the liquid tube, then the device becomes more stable and flexible, but the device complexity increases
Solution Approach 1:
The suction means are positioned to utilize the surrounding water environment for stabilization. The system uses the water itself as a stabilizing medium, with the suction means drawing water from the environment and using the resulting pressure differential to stabilize the tubular container, rather than requiring external stabilization mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables flexible operation with any vessel type, significantly increasing the volume of bottom material that can be displaced per hour, up to 3000 m³, while stabilizing the device and optimizing energy use by adjusting power distribution between propeller and suction systems.
