Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional thermal decomposition process is used to convert waste into usable gases, then waste can be reprocessed and energy can be produced, but carbon dioxide molecules and hydrocarbon compounds are formed as unwanted products, reducing gas quality and production efficiency
Solution Approach 1:
The gasification process is divided into two distinct stages: a gasification unit that performs thermal decomposition to produce raw gas, and a purification unit that separately removes harmful components (carbon dioxide and hydrocarbons) through adsorption. This segmentation allows each unit to optimize its function, improving overall gas production efficiency while eliminating harmful factors.
Solution Approach 2:
The purification unit extracts and removes unwanted carbon dioxide molecules and hydrocarbon compounds from the raw gas produced during thermal decomposition. By taking out these harmful components through adsorption, the system maintains high gas production efficiency while delivering high-purity usable gas.
2Use of energy by moving object
If thermal decomposition is applied to waste with large molecules, then energy can be recovered, but the large molecular size causes carbon atoms to form unwanted carbon dioxide and hydrocarbon compounds, reducing the maximum amount of usable gases that can be produced
Solution Approach 1:
The system performs preliminary thermal decomposition to break down large waste molecules into smaller gaseous components, recovering energy in the process. Then, the purification unit separately removes harmful products (carbon dioxide and hydrocarbons) that form during this decomposition, thereby maximizing the quantity of usable gases from the original waste material.
Solution Approach 2:
The purification unit extracts harmful carbon dioxide and hydrocarbon compounds from the gas mixture produced during waste decomposition. This extraction allows the system to recover maximum energy from waste while delivering a higher quantity of pure usable gases by removing the unwanted components that would otherwise reduce the net gas yield.
3Manufacturing precision
If adsorbing devices are used to remove carbon dioxide, then gas purity can be improved, but the adsorbing devices require switching between adsorbing and desorbing states, which may interrupt the gas production process
Solution Approach 1:
The purification unit is segmented into multiple adsorbing devices that can operate independently. While one device is in the adsorbing state to maintain high gas purity, another device can be in the desorbing state to regenerate. This segmentation enables continuous gas production without interruption, as multiple devices work in coordination to maintain both purity and productivity.
Solution Approach 2:
The system maintains continuous gas production by coordinating multiple adsorbing devices in different operational states. While some devices are adsorbing to ensure high gas purity, others are desorbing to regenerate their capacity. This continuous coordination ensures that gas flow is never interrupted, maintaining both high purity and continuous productivity.
