Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional plane wave and Bloch wave paradigms are used to understand elastic waves in phononic structures, then the understanding is based on simple geometric models, but the ability to achieve robust designs with immunity to imperfections is limited
Solution Approach 1:
The patent changes the fundamental parameters of elastic wave systems by introducing rotational degrees of freedom and spinor characteristics to phonons. This transforms conventional acoustic phonons into rotational phonons with fermion-like behavior, enabling topological protection and robustness against imperfections without requiring complex geometric structures
Solution Approach 2:
The patent substitutes the conventional mechanical wave propagation model with a quantum-like field theoretical model. By applying Dirac's formalism to elastic waves, the system achieves fermion-like behavior and topological protection, replacing simple geometric complexity with fundamental changes in wave mechanics
2Adaptability or versatility
If geometric complexity of phononic crystals and acoustic metamaterials is explored to achieve progress in elastic wave behavior, then new wave phenomena can be observed, but the designs become complex and difficult to manufacture
Solution Approach 1:
Instead of changing the geometry of phononic structures, the patent changes the fundamental parameters of the wave itself by introducing rotational degrees of freedom and spinor characteristics. This allows rotational wave support through fundamental wave physics rather than complex geometric arrangements
Solution Approach 2:
The patent replaces the need for complex geometric structures with a field theoretical approach using Dirac's formalism. This substitution transforms the problem from one requiring manufactured geometric complexity to one solved by fundamental changes in wave mechanics and quantum-like field theory
3Adaptability or versatility
If phase-based encoding of information is implemented using fermion-like behavior of rotational phonons, then new information processing functionalities are achieved, but the system complexity increases
Solution Approach 1:
The patent introduces the spinor part of the wave function as an intermediary that carries topological information. This spinor acts as a mediator between the mechanical wave and the information encoding process, enabling phase-based information processing through topological protection without requiring complex encoding mechanisms
Solution Approach 2:
The patent changes the encoding parameter from conventional amplitude or frequency modulation to phase encoding based on the spinor state. This fundamental parameter change enables new information processing functionalities while leveraging the inherent topological protection of the system
