Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a grinding cell with rotating blades is used to process waste, then waste can be ground and shredded, but frequent blockages and jamming occur due to excessive accumulation of shredded material
Solution Approach 1:
The patent introduces a vibration mechanism that applies mechanical vibrations to the grinding cell during waste processing. This vibration prevents excessive accumulation of shredded material by keeping particles in motion, thereby eliminating jamming and blockages while maintaining continuous operation and high processing capacity
Solution Approach 2:
The patent implements periodic reversal of the rotating blades' direction of rotation. This periodic action prevents material accumulation by alternately changing the flow direction of shredded waste, ensuring continuous movement through the grinding cell and preventing blockages that would otherwise occur with unidirectional rotation
2Ease of operation
If the processing chamber is opened for loading and discharging waste, then waste can be introduced and removed, but non-piped emissions contaminate the outer environment with dust and volatile substances
Solution Approach 1:
The patent introduces an inert gas (such as nitrogen or carbon dioxide) into the processing chamber to create an inert atmosphere during waste loading and discharge operations. This inert atmosphere prevents dust and volatile substances from escaping into the outer environment, eliminating environmental contamination while allowing normal loading and discharge operations to proceed
Solution Approach 2:
The patent introduces a washing air flow system that acts as an intermediary between the processing chamber and the outer environment. This washing air flow creates a protective barrier during opening/closing operations, capturing and containing dust and volatile substances, thereby preventing their release into the environment while allowing waste to be loaded and discharged
3Ease of manufacture
If a compact design is used to improve transportability, then the plant can be easily installed in remote locations, but access for maintenance and operation becomes more difficult
Solution Approach 1:
The patent divides the waste processing plant into modular segments or components that can be easily assembled and disassembled. This segmentation allows the compact plant to be transported as modular units to remote locations while still permitting easy access to individual components for maintenance and repair operations
4Object-generated harmful factors
If hermetic sealing is used to prevent emissions, then environmental contamination is reduced, but heat dissipation from the processing chamber becomes more difficult
Solution Approach 1:
The patent introduces a washing air flow as an intermediary medium that circulates between the processing chamber and the external environment. This washing air flow serves dual purposes: it maintains hermetic sealing to prevent emissions while simultaneously carrying heat away from the processing chamber, thereby solving both emission control and heat dissipation requirements
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 effectively reduces waste volume by up to 80%, minimizes environmental contamination, and is easily transportable and installable, ensuring safe and efficient processing with reduced operational risks and costs.
Implementation Method 1
a washing air flow is generated inside the housing, for cooling the processing chamber
Implementation Method 2
a vacuum pump adapted to evacuate the gaseous effluent from the processing chamber
Implementation Method 3
a liquid-ring vacuum pump that contributes, thanks to the mixing with a cooling fluid, to the condensation of most of the steam
