Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If repeated purging of the applicator box is performed for batch treatment, then the microwave energy can be applied to break down organic materials, but the purge gas must be constantly replaced leading to waste
Solution Approach 1:
The applicator box is purged of atmospheric oxygen before microwave energy is applied, and the inert gas environment is maintained throughout the treatment process. This preliminary preparation prevents ignition hazards from the start, eliminating the need for repeated purging operations and reducing purge gas consumption.
Solution Approach 2:
An inert gas atmosphere is created within the applicator box by purging atmospheric oxygen before microwave treatment. This inert environment prevents ignition of organic materials while allowing continuous operation without repeated purging, thereby reducing purge gas waste while maintaining safety.
2Reliability
If a constant flow of purge gas is used to maintain a purged environment for continuous treatment, then ignition of materials is avoided, but the purge gas must constantly be replaced leading to waste
Solution Approach 1:
A constant inert gas atmosphere is maintained in the applicator box during continuous treatment to prevent ignition of organic materials. This steady inert environment eliminates the need for constant purge gas replacement, reducing gas consumption while maintaining safety throughout the continuous process.
3Ease of operation
If the applicator box is opened to remove resultant material, then the treated material can be discharged, but purge gas is lost during this operation
Solution Approach 1:
The applicator box is equipped with a purge gas supply system that maintains inert atmosphere pressure above atmospheric pressure. When the box is opened for material removal, the positive pressure differential prevents atmospheric air from entering and purge gas from escaping, minimizing gas loss during the opening operation while allowing easy material discharge.
