Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If thermal convection is used to heat air for desorption, then desorption can be achieved, but power consumption increases greatly due to heat loss and radiation heat loss
Solution Approach 1:
The patent extracts the heating function from the air stream and places it directly at the adsorptive material surface through an electrical heater. This separates the heating action from the air convection process, eliminating the need to heat large volumes of air and thereby reducing heat loss and power consumption.
Solution Approach 2:
The patent introduces an electrical heater as an intermediary device between the power source and the adsorptive material. This intermediary directly transfers thermal energy to the adsorptive material without requiring air as a heat transfer medium, thus eliminating radiation heat loss from heater surfaces and reducing overall energy consumption.
2Volume of moving object
If the adsorption device is size-reduced, then compactness is improved, but there is not enough space for installing a heater with enough area for heat-exchange
Solution Approach 1:
The patent applies local quality by concentrating the heating function at the specific location where adsorptive material is present. The electrical heater is positioned in direct contact with or adjacent to the adsorptive material, providing localized heating exactly where needed rather than requiring a large heater surface area for general air heating.
Solution Approach 2:
The patent replaces the mechanical thermal convection system with an electrical heating system. This substitution eliminates the need for large heater surfaces and air circulation mechanisms, allowing for a compact device design while maintaining effective desorption capability.
3Use of energy by moving object
If reticular metal electrodes are used for electrical regeneration, then energy consumption is reduced, but the electrodes block channels and reduce effective surface area for regeneration
Solution Approach 1:
The patent employs porous adsorptive materials that allow electrical energy to penetrate and distribute throughout the material structure. The porous nature enables heating and regeneration without requiring solid electrode structures that would block channels, thus maintaining effective surface area while achieving energy-efficient regeneration.
Solution Approach 2:
The patent substitutes physical electrode structures with electrical energy applied through the adsorptive material itself. Instead of using metal electrodes that occupy space and block channels, the system uses electrical fields or currents that can penetrate porous materials without physical obstruction, maintaining full surface area availability.
