Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional hydraulic systems extract energy from water flow, then gravitational potential energy is utilized, but interior pressure energy is wasted and not utilized
Solution Approach 1:
The patent segments the energy extraction process into two distinct components: gravitational potential energy extraction (through water flow) and interior pressure energy extraction (through pressure differential mechanisms). By dividing the system into separate functional elements that handle each energy type independently, both energy sources can be captured and converted into electrical energy simultaneously, eliminating the waste of pressure energy in conventional single-purpose hydraulic systems.
Solution Approach 2:
The hydraulic pressure power battery system performs multiple functions: it generates electricity from gravitational potential energy, extracts energy from interior pressure, stores energy in battery form, and can operate in various fluid environments (water, oil, etc.). This multi-functional design allows the same system to utilize both pressure and gravitational energy from the same fluid source, achieving comprehensive energy recovery that conventional single-function systems cannot accomplish.
2Power
If objects change volume to create buoyancy difference for energy extraction, then energy can be obtained from static liquid, but the volume changing process consumes energy
Solution Approach 1:
The system employs pressure differential mechanisms that automatically respond to fluid pressure changes without requiring active volume control. The pressure-sensitive elements self-adjust their state based on the surrounding pressure environment, converting pressure energy directly into mechanical motion and electrical energy. This self-service mechanism eliminates the need for external energy input to change volume, as the system passively exploits the existing pressure gradients in the fluid.
Solution Approach 2:
The patent replaces traditional mechanical volume-changing mechanisms (which require actuators, motors, or manual operation) with pressure-driven mechanical elements that automatically expand or contract in response to pressure differentials. This substitution eliminates the energy-consuming control systems while maintaining the buoyancy difference effect, allowing energy extraction from static liquid without the penalty of active volume control energy consumption.
3Productivity
If fluid pressure gradient fields are applied to rotating structures, then kinetic energy can be extracted efficiently, but dynamic sealing is required to isolate fluid pressures
Solution Approach 1:
The patent utilizes ferrofluid seals, which are a specialized form of hydraulic sealing where a magnetically controlled fluid creates a seal between rotating and stationary components. The ferrofluid forms a flexible barrier that maintains pressure isolation while accommodating rotational motion, eliminating the need for complex mechanical contact seals. This approach achieves reliable dynamic sealing with minimal friction and wear, supporting efficient energy extraction from the pressure gradient field.
Solution Approach 2:
The system employs magnetic field parameter changes to control the ferrofluid seal properties. By adjusting the magnetic field strength and distribution, the ferrofluid's viscosity and sealing characteristics can be dynamically optimized for different operating conditions. This parameter control allows the seal to maintain effectiveness across varying pressure differentials and rotational speeds, reducing complexity compared to fixed-design mechanical seals while supporting high-efficiency energy extraction.

This approach enables the conversion of fluid pressure energy into mechanical energy with high efficiency, providing long-lasting and high-capacity power for various applications, including mobile electronics, vehicles, and medical devices, without consuming additional energy.
Implementation Method 1
The ferrofluid has both the liquidity of ferrofluid and a solid magnetic material with magnetic. The fluid has no magnetic attraction at the time of static state, but when the exterior magnetic field is applied; it is shown that the fluid is magnetic.
Implementation Method 2
The seals can be a ferrofluid seal, mechanical seal, or a combination of mechanical seals and the ferrofluid seal. The so-called ferrofluid seal is to use ferrofluid to shield the fluid for building environment of air, and a vacuum environment that includes the shielding structure in the fluid.
Implementation Method 3
Typically, using the techniques described below, by using fluid gravity and buoyancy as exterior forces, a unidirectional and asymmetrical force is applied to the rotating body to generate an exterior torque to achieve the purpose of pushing the rotation of the rotating body.
Implementation Method 4
The hydrostatic pressure can also be classified into two different pressures based on the directions of the downward liquid column pressure and the direction of upward buoyancy by putting an object into the fluid.
