Engineering Contradiction Analysis
1Reliability
If traditional semiconductor memory is used, then data storage function is achieved, but the memory cannot meet the stringent requirements for intelligent robots and bioengineering applications
Solution Approach 1:
The patent replaces traditional semiconductor-based electronic memory systems with a mechanical metamaterial-based memory system. The core innovation lies in using mechanical postbuckling phenomena and magnetic field interactions to achieve data storage and retrieval, thereby substituting conventional electronic mechanisms with mechanical ones to meet specialized application requirements in intelligent robots and bioengineering.
Solution Approach 2:
The patent employs composite material structures combining mechanical metamaterials with magnetic components. The mechanical metamaterials exhibit unique postbuckling behaviors that can be controlled by magnetic fields, creating a composite system that integrates mechanical deformation capabilities with magnetic actuation for enhanced memory functionality in specialized applications.
2Adaptability or versatility
If mechanical metamaterials and postbuckling phenomenon are used for data storage, then unique mechanical structure is achieved, but the complexity of magnetic force-driven mode conversion increases
Solution Approach 1:
The patent introduces magnetic fields as an intermediary mechanism to control the postbuckling behavior of mechanical metamaterials. By using magnetic forces as the mediating agent, the system can remotely and precisely control the mechanical deformation modes without direct physical contact, simplifying the overall control architecture despite the complex underlying mechanical behavior.
Solution Approach 2:
The patent exploits changes in mechanical parameters (such as buckling mode, deformation amplitude, and structural configuration) of the mechanical metamaterials in response to magnetic field variations. By controlling these parameter changes through adjustable magnetic field strength and orientation, the system achieves multiple data storage states without increasing structural complexity.
3Quantity of substance
If data is stored through mechanical structure characteristics, then data storage is achieved, but the conversion from mechanical states to electrical signals requires signal collection
Solution Approach 1:
The patent implements a feedback mechanism where the mechanical deformation states of the metamaterials are converted into electrical signals through magnetic coupling. The signal collection unit detects changes in magnetic field distribution caused by mechanical buckling modes and converts them into readable electrical signals, providing feedback that confirms the stored data state and enables reliable readout.
