Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the draft of the hull is increased to enhance carrying capacity, then the carrying capacity is improved, but the energy consumption increases and speed decreases
Solution Approach 1:
The patent employs adjustable diversion pressure plates that can change their angle dynamically through hydraulic cylinders. This allows the hull to adapt its underwater profile - creating deeper effective draft when carrying capacity is needed and reducing draft when speed and energy efficiency are prioritized, thus resolving the contradiction between carrying capacity and energy consumption
Solution Approach 2:
The invention changes the physical parameter of draft depth by adjusting the angle of diversion pressure plates. By modifying the angle parameters of these plates, the hull's effective draft is altered, enabling the system to achieve different carrying capacities while managing energy consumption levels through parameter variation
2Quantity of substance
If the draft of the hull is increased to enhance carrying capacity, then the carrying capacity is improved, but the speed decreases
Solution Approach 1:
The adjustable diversion pressure plates enable dynamic modification of the hull's underwater profile. When high speed is needed, the plates are adjusted to reduce effective draft, minimizing resistance. When carrying capacity is prioritized, the plates create deeper draft. This dynamic adjustment resolves the contradiction between carrying capacity and speed
3Use of energy by moving object
If the draft of the hull is reduced to decrease energy consumption, then the energy consumption is reduced, but the carrying capacity decreases
Solution Approach 1:
The invention divides the hull's underwater surface into multiple adjustable segments (diversion pressure plates). Each segment can be independently adjusted to optimize local water flow and buoyancy distribution. This segmentation allows the system to maintain adequate carrying capacity while reducing overall draft to lower energy consumption, as the segmented plates can be positioned to minimize resistance while preserving necessary buoyancy
4Speed
If the draft of the hull is reduced to improve speed, then the speed is improved, but the carrying capacity decreases
Solution Approach 1:
The dynamic adjustment capability of the diversion pressure plates allows the system to optimize for speed by reducing effective draft when high velocity is needed, while preserving the ability to increase draft when carrying capacity becomes the priority. This dynamic adaptability resolves the contradiction between speed and carrying capacity
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
The mechanism effectively reduces the draft of the hull by optimizing water flow and buoyancy, enhancing speed and reducing energy consumption while maintaining maneuverability and carrying capacity.
Implementation Method 1
The first hydraulic cylinder is arranged in the hull. The rod body of the first hydraulic cylinder passes through the inclined plate at the front end of the hull and is hinged to the upper end of the first diversion pressure plate
Implementation Method 2
adjust the water flow at the bottom of the hull, increase the buoyancy of the hull and reduce the draft
Implementation Method 3
The guide baffles on both sides are used to direct the water flow to the hull
Implementation Method 4
The propeller assembly is connected to the winding drum on the hull by a chain. Through the winding drum, the chain can be retracted and released to control the lifting and lowering of propeller assembly

AI summary
The invention discloses a hull auxiliary mechanism for reducing the draft of a hull, which includes a guide baffle on both sides of the hull. The two ends of the guide baffle extend out of the front and rear ends of the hull. The lower end of the guide baffle extends out of the bottom of the hull. The front and rear ends of the hull are flat inclined plates. The bottom of the hull is a flat plate; the auxiliary mechanism also includes a water resistance mechanism, and the water resistance mechanism includes a first diversion pressure plate, a second diversion pressure plate and a third diversion pressure plate. Both sides of the guide baffle are used to direct the flow of water to the hull. At the same time, there are three groups of diversion pressure plates at the bottom of the hull. The angles of the diversion pressure plates are adjusted by the hydraulic cylinders, so as to adjust the water flow at the bottom of the hull, increase the buoyancy of the hull and reduce the draft.
