Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If binary state electronic switches are used for computation, then computing speed and processing power can be increased, but power consumption increases and computational states are limited to binary
Solution Approach 1:
The patent changes the fundamental parameter of computation from binary electronic states to multi-state chemical concentration gradients. By utilizing continuous concentration variations of chemical species rather than discrete binary states, the system achieves both reduced power consumption and increased computational versatility with multiple stable states.
Solution Approach 2:
The patent substitutes electronic/magnetic fields with chemical reaction-diffusion systems. Instead of using electronic switches and magnetic storage, the invention employs chemical reactions and spatial concentration gradients to perform computation and store data, fundamentally replacing the electronic system with a chemical one.
2Productivity
If conventional electronic computers are used, then processing power increases over time, but the paradigm remains the same with separate processor and memory on silicon substrate
Solution Approach 1:
The patent merges the functions of processing and memory into a single chemical reaction-diffusion system. The same chemical medium that performs computational operations through reaction-diffusion dynamics also stores information through spatial concentration patterns, eliminating the need for separate processor and memory components.
Solution Approach 2:
The chemical reaction-diffusion system serves multiple functions simultaneously: it performs logical operations, stores data spatially, and enables pattern recognition, all within the same physical medium. This universal system replaces the specialized separation of compute and storage functions found in conventional computers.
3Use of energy by moving object
If chemical reactions are used for information processing, then power consumption is reduced and computational states are increased, but reliability and repeatability of logic operations must be established
Solution Approach 1:
The patent segments the continuous chemical system into discrete reaction zones or compartments, each capable of performing specific logical operations. This segmentation allows individual logic gates to be defined and controlled separately, improving the reliability and repeatability of each operation while maintaining the overall chemical-based system.

Implementation Method 1
The reaction mixture may be a reaction mixture for a chemical oscillator reaction. The chemical oscillator reaction may be selected from the group consisting of a Belousov-Zhabotinsky (BZ) reaction, a Briggs-Rauscher reaction and a Bray-Liebhafsky reaction
Implementation Method 2
The reaction mixture may be a reaction mixture having a colour change in its reaction, and here the analytical device has an optical sensor to analyse the colour change in one or more reaction spaces. An oscillation reaction may therefore be oscillations between species of different colour.
