Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If conventional electronic computing systems are used, then processing power and speed are high, but power consumption is excessive and binary state processing limits computational flexibility
Solution Approach 1:
The patent replaces electronic computing systems with a chemical computing system that uses chemical reactions (specifically Belousov-Zhabotinsky oscillating reactions) to perform computations. This substitution fundamentally changes the physical basis of computation from electronic to chemical, enabling multi-state processing through continuous chemical concentration variations rather than binary electronic states, thereby reducing power consumption while maintaining computational capability
Solution Approach 2:
The patent utilizes continuous variations in chemical reaction parameters (concentration of reactants, oscillation amplitude, reaction rate) to encode multiple computational states. By monitoring parameters such as the concentration of chemical species or the amplitude of oscillations in the BZ reaction, the system can represent more than binary states, increasing computational flexibility without requiring proportionally higher power input
2Adaptability or versatility
If silicon-based substrates are used, then device fabrication is well-established, but alternative substrates are needed for low-power and multi-state computation
Solution Approach 1:
The patent employs chemical reactions, specifically oscillating reactions like Belousov-Zhabotinsky, which naturally exhibit continuous parameter variations in concentration and oscillation amplitude. These intrinsic chemical parameter changes enable the system to represent multiple computational states without requiring complex additional hardware, thus achieving high adaptability through the natural behavior of the chemical system
Solution Approach 2:
The chemical computing system is designed to perform multiple functions using the same underlying chemical platform. The oscillating chemical reactions can be configured to perform logic operations, data storage, and signal processing, making the system universally applicable to various computational tasks while relying on the well-understood chemistry of oscillating reactions
3Adaptability or versatility
If binary state processing is used, then system simplicity is maintained, but computational flexibility and multi-state processing are limited
Solution Approach 1:
The patent exploits continuous parameter changes in chemical reactions, particularly the oscillating concentration of chemical species in BZ reactions. By monitoring these continuously varying parameters, the system can distinguish multiple computational states (more than binary) without requiring proportionally complex detection or control mechanisms, thus achieving computational flexibility with moderate system complexity
