Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If specialized plants are designed for single product production, then production efficiency for that specific product is improved, but byproducts are discarded and large surface areas are required

Engineering Contradiction:
Improveproduction efficiencyVSAvoidbyproduct waste
Core Design Contradiction:
ProductivityVSLoss of substance

Solution Approach 1:

The plant is designed with multi-functionality to produce multiple products simultaneously including fresh water, salt, hydrogen, oxygen, and electricity from a single salt water input system, eliminating byproduct waste and maximizing resource utilization

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If specialized plants are designed for single product production, then production efficiency for that specific product is improved, but large surface areas are occupied

Engineering Contradiction:
Improveproduction efficiencyVSAvoidsurface area occupied
Core Design Contradiction:
ProductivityVSArea of stationary object

Solution Approach 1:

The plant integrates multiple production functions (desalination, salt extraction, hydrogen production, oxygen production, and electricity generation) into a single facility, thereby producing multiple valuable products simultaneously while occupying a reduced surface area compared to multiple separate specialized plants

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Power

If hydroelectric turbines are used for electricity generation, then electricity production is improved, but water resources are consumed

Engineering Contradiction:
Improveelectricity generationVSAvoidwater consumption
Core Design Contradiction:
PowerVSLoss of substance

Solution Approach 1:

The system recovers and reuses water that would otherwise be lost or discarded. The salt water is circulated through the system, with fresh water extracted for turbine use, and the remaining brine is reused in subsequent desalination and product generation processes, minimizing overall water consumption

Inventive Principle:
Principle #34Discarding and recovering

Solution Approach 2:

The plant generates its own electricity through hydroelectric turbines powered by water from its own operations, and produces its own hydrogen and oxygen through electrolysis, creating a self-sustaining system that reduces external resource inputs

Inventive Principle:
Principle #25Self-service

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 plant efficiently generates electricity and produces multiple valuable products from salt water, reducing environmental impact by utilizing renewable energy sources and optimizing resource utilization, while allowing for flexible operation and maintenance.

Implementation Method 1

The hydroelectric turbines are designed in such a way that their rotation is driven by the water taken from the reservoir by means of a pipe. In other words, the potential energy of the water from the reservoir is converted into kinetic energy and by causing rotation of the alternators - turbines is converted into electricity.

Scientific EffectHydroelectric energy conversion: Water Turbine

Implementation Method 2

a photovoltaic apparatus (8) designed to convert solar energy into electrical energy

Methodology Applied
Scientific EffectPhotovoltaic effect: Photovoltaic Effect

Implementation Method 3

a desalination apparatus (9) designed to separate the salt water (AS) into salt (S) and fresh water (A)
