Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a dam is constructed to generate large amount of electricity, then power generation capacity is improved, but the limitation of construction location increases due to the need for large height difference

Engineering Contradiction:
Improvepower generation capacityVSAvoidconstruction location flexibility
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The invention divides the water flow energy conversion process into two independent stages: first, water flow raises the water level in a storage tank; second, the stored water's potential energy moves a floating body vertically to drive the generator. This segmentation eliminates the need for a single large-height dam structure, enabling construction at locations with smaller height differences while maintaining power generation capacity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention transitions from direct horizontal water flow rotation (conventional hydroelectric) to vertical water level change driving a floating body's vertical motion. This dimensional change from horizontal to vertical energy conversion enables the system to operate with smaller height differences, expanding construction location flexibility.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Productivity

If hydraulic turbines are rotated to convert water flow into rotational energy, then electricity is generated, but the conversion efficiency is reduced due to unavoidable energy waste

Engineering Contradiction:
Improveelectricity generation efficiencyVSAvoidenergy conversion waste
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The invention replaces the conventional hydraulic turbine's direct mechanical rotation with a two-stage process: water flow first raises water level (potential energy storage), then the floating body's vertical motion drives the generator. This substitution reduces energy loss by separating the flow energy capture from the rotation generation, improving overall conversion efficiency.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The storage tank performs a preliminary action by storing water at an elevated level, converting kinetic energy of water flow into potential energy before the actual power generation occurs. This preliminary energy storage and transfer reduces direct energy loss during conversion, improving overall efficiency.

Inventive Principle:
Principle #10Preliminary action

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 system efficiently generates electricity by utilizing the buoyancy and gravity of water to move a floating body vertically, converting this motion into electrical energy through a rack and pinion gear system, enabling continuous power generation with reduced location limitations compared to traditional hydroelectric dams.

Implementation Method 1

As the water is stored in the storage tank, the water level in the storage tank rises and the floating body is moved upward by the buoyancy of the water

Methodology Applied
Scientific EffectBuoyancy: Archimedes' Principle (Buoyancy)

Implementation Method 2

As the water in the storage tank is discharged to the outside, the water level in the storage tank descends and the floating body is moved downward by the gravity of the floating body

Methodology Applied
Scientific EffectGravity: Gravitation

Implementation Method 3

since the outlet port is provided at a position lower than the inlet port, the water flow is formed from the inlet port to the outlet port by the gravity when the opening and closing mechanism of the outlet port is opened

Methodology Applied
Scientific EffectGravity-driven water flow: Gravitation
