Solution Overview

Problem

Conventional hydraulic pumps used for supplying water to high or remote places require motors or engines, leading to high production and running costs due to the consumption of high voltage power or fuel, making them economically disadvantageous.

Innovation Solution

A hydraulic pump design featuring a pump outer wall body with a moving pressing member that uses buoyancy to compress a lower reservoir and transport water, eliminating the need for motors by utilizing check valves and open/close valves controlled by mechanical means, allowing water to be pumped efficiently without electric power.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a motor or engine is used in the conventional hydraulic pump, then the pump can effectively transport water to high or remote places, but the production costs and running costs increase significantly due to high voltage power or fuel consumption

Engineering Contradiction:
Improvewater transport capabilityVSAvoidproduction cost
Core Design Contradiction:
ProductivityVSEase of manufacture

Solution Approach 1:

The invention extracts and eliminates the motor or engine component from the hydraulic pump system. By removing this expensive power-consuming component, the patent achieves water transport functionality through purely mechanical means using floating bodies and valve mechanisms, thereby significantly reducing both production costs and running costs while maintaining water transport capability

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention implements self-service by using the energy of the water flow itself and buoyancy forces to drive the pumping mechanism. The floating bodies automatically move with water level changes, and the valve mechanisms automatically open and close based on pressure differences, eliminating the need for external power sources and reducing operational costs

Inventive Principle:
Principle #25Self-service

AI summary

A hydraulic pump comprises a moving pressing member to compress a lower reservoir to move downward, and to move upward according to the change of buoyancy by the supply and discharge of the water into an inner space of the moving pressing member. A pumping pipe transports water in the lower reservoir outside of the pump.
