Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If compressor devices operate at high rotational speeds to increase productivity, then compression capacity increases, but vibrations and pressure pulsations increase causing noise and potential damage
Solution Approach 1:
An adapter of acoustic impedance is introduced as an intermediary component between the compressor element and the fluid duct outlet. This adapter includes an expansion chamber that acts as a mediator to smooth pressure fluctuations and reduce vibrations caused by high-speed operation, thereby maintaining productivity while reducing harmful effects.
2Use of energy by moving object
If compressor devices are designed to compress fluid efficiently, then energy consumption decreases, but pressure pulsations and vibrations persist causing noise
Solution Approach 1:
The adapter of acoustic impedance serves as a mediator that reduces noise generated during efficient compression operations. The expansion chamber within the adapter smooths pressure waves and diminishes vibrations that cause noise, allowing the compressor to maintain high energy efficiency while reducing harmful noise emissions.
3Productivity
If fluid evacuation is improved to increase productivity, then compression efficiency increases, but pressure fluctuations worsen causing damage
Solution Approach 1:
The adapter of acoustic impedance acts as a protective intermediary between the compression process and the fluid duct outlet. The expansion chamber smooths pressure fluctuations generated during efficient fluid evacuation, preventing these fluctuations from causing damage to the equipment while maintaining high productivity.
