Engineering Contradictions & Design Principles
Engineering 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
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
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
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
3Power
If hydroelectric turbines are used for electricity generation, then electricity production is improved, but water resources are consumed
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
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
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.
Implementation Method 2
a photovoltaic apparatus (8) designed to convert solar energy into electrical energy
Implementation Method 3
a desalination apparatus (9) designed to separate the salt water (AS) into salt (S) and fresh water (A)
Implementation Method 4
an electrolysis apparatus (11) designed to make available hydrogen (H2) and oxygen (O2) from the fresh water (A)
