Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional acoustic energy harvesting systems are used, then they can harvest acoustic energy, but they require large structures for sound focusing which makes them costly and inefficient
Solution Approach 1:
The system divides the acoustic energy harvesting function into multiple independent resonators (first resonator, second resonator, third resonator, and fourth resonator) that can be separately manufactured and then assembled together, reducing the complexity and cost of manufacturing a single large structure
Solution Approach 2:
The resonators are arranged in a nested configuration where the second resonator is positioned between the first and third resonators, and the fourth resonator is positioned between the third and first resonators, creating a compact nested structure that achieves sound focusing without requiring large individual structures
2Productivity
If conventional acoustic energy harvesting systems are used, then they can harvest acoustic energy, but they have low amplification ratio requiring large structures
Solution Approach 1:
The system merges the functionality of multiple resonators into a single integrated acoustic energy harvesting system where the resonators work together to amplify acoustic energy, achieving high amplification ratio through cooperative resonance rather than requiring a single large structure
Solution Approach 2:
The resonators are arranged in a specific spatial configuration around the central acoustic energy harvester, utilizing three-dimensional spatial arrangement to achieve sound focusing and amplification without increasing the overall structure size in any single dimension
