Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hydraulic power generation systems rely on complex and costly infrastructure, requiring large ballast weights and mechanical motion to convert fluid pressure into energy, which is inefficient and dependent on water conditions.
Innovation Solution
A power generation system that utilizes the correlation between increasing depth and hydrostatic pressure to drive a hydraulic cylinder, where ballast changes in buoyancy are powered by an on-board battery or external power, allowing the system to sink and rise autonomously, generating energy through hydrostatic pressure changes without the need for external pumping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stress or pressure
If large ballast weights and mechanical motion are used to drive hydraulic cylinders, then hydraulic pressure is generated, but the system becomes complex, costly, and inefficient
Solution Approach 1:
The patent replaces complex mechanical systems (ballast weights, external pumps, mechanical linkages) with a direct hydrostatic pressure system. The hydraulic cylinder is positioned to directly experience increasing water pressure with depth, eliminating the need for mechanical transmission components and external pumping mechanisms.
Solution Approach 2:
The invention extracts and utilizes the hydrostatic pressure component directly from the water column. By positioning the hydraulic cylinder to face upward and expose its piston to water pressure, the system extracts energy directly from the pressure gradient without requiring mechanical conversion systems.
2Stress or pressure
If large ballast weights are used to drive hydraulic cylinders, then hydraulic pressure is generated, but energy consumption increases
Solution Approach 1:
The patent eliminates energy-consuming mechanical systems by using the natural hydrostatic pressure field. Instead of expending energy to lift and drop ballast weights or operate external pumps, the system passively converts the potential energy already present in the water column into hydraulic pressure through direct pressure application.
Solution Approach 2:
The system uses the natural hydrostatic pressure gradient of the water column to drive itself. The increasing pressure with depth automatically drives the hydraulic cylinder during descent, and the system requires no external energy input for the pressure generation process.
3Stress or pressure
If external pumping is used to move fluid into and out of the system, then hydraulic pressure is generated, but the system becomes dependent on water conditions and requires costly infrastructure
Solution Approach 1:
The patent replaces external pumping infrastructure with a direct hydrostatic pressure system. The hydraulic cylinder is positioned to directly experience water pressure changes during vertical movement, eliminating the need for external pumps, pipes, and associated infrastructure that would require maintenance and are sensitive to water conditions.
Solution Approach 2:
The system generates its own hydraulic pressure through its vertical movement in the water column. By positioning the cylinder to face upward and exposing the piston to ambient water pressure, the system self-generates the necessary pressure during descent without requiring external assistance or infrastructure.

AI summary
The system utilizes fluid pressure achieved by increasing depth as a primary component for generation of energy. The system operates by varying its depth through changes in buoyancy. The ballast changes are controlled by electronics powered by a battery charged by a generator driven by a hydraulic system. Rather than utilizing a motor driven pump to generate pressure in the hydraulic system, a piston-like cylinder is applied pressure by the change in hydrostatic pressure as depth increases and draws fluid back into the cylinder as pressure decreases. As the system sinks, outside pressure forces hydraulic fluid to power a generator that charges a battery and powers a pump to deballast. As the system rises, the lowering of ambient pressure, and other internal forces, causes the hydraulic fluid to return to its initial state, where once the ballast begins to take in fluid, the whole process will continue to repeat.
