Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If multiple-part assembled bushings are used for sealing, then the device can be assembled from standard components, but the reliability is insufficient due to sealing issues between parts
Solution Approach 1:
The patent merges multiple sealing components into a single monolithic dielectric cap structure that integrates the sealing function with the electrical insulation function. This eliminates the need for separate bushings and multiple sealing interfaces, thereby improving reliability while maintaining ease of manufacture through a unified design approach
2Device complexity
If rod-type electrodes are used, then the device structure is simple, but the production output is limited due to electrode diameter constraints
Solution Approach 1:
The patent transitions from rod-type electrodes to tubular electrodes, adding a dimensional change from solid cylindrical to hollow cylindrical structure. This dimensional change allows electrolyte flow through the electrode interior, increasing the effective surface area for electrochemical reactions and thereby improving production output while maintaining structural simplicity
3Ease of operation
If the device longitudinal axis must be positioned vertically, then the sealing and operation are simplified, but the operational flexibility and applicability are reduced
Solution Approach 1:
The patent introduces a movable diaphragm design that can dynamically adjust its position and orientation to maintain proper sealing and functional performance regardless of the device's installation angle. This dynamic adaptation allows the device to operate effectively in various orientations, thereby improving versatility while maintaining ease of operation through automated adjustment mechanisms
4Length of stationary object
If the channel diameter is restricted by the clearance between electrodes and diaphragm, then the electrode spacing is minimized, but the production output is limited
Solution Approach 1:
The patent segments the electrolyte flow path into multiple channels that are distributed around the tubular electrodes. This segmentation allows each channel to have adequate diameter for high flow rates while maintaining compact overall device dimensions, thereby resolving the contradiction between minimized electrode spacing and maximized production output

AI summary
The disclosure relates to an electrochemical treatment of liquids and production of gases. Increased operating efficiency of an electrochemical device is achieved through the combination of measures: (1) sealing of the device on an element-by-element basis; (2) transfer of the liquid and gaseous phase interface into a passive extension of an anode chamber; (3) utilization of a tubular cathode as an inner wall and a cylindrical anode with an external coating as an outer wall; (4) positioning of channels and determining their dimensions so as to maintain helicity of electrolyte movement combined with the increase of the production output; (5) positioning and design of terminals, which provide for the reduction of their heating; and (6) ability of the device to operate under the conditions, when its longitudinal axis deviates from the vertical line by an angle of γ≦85° and under pumping conditions.
