Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a metal plate pressing board is used to fasten the anode electrocatalyst layer and solid polymer electrolyte membrane, then the initial compression force is sufficient, but the metal plate undergoes plastic deformation over time, reducing compression force and ozone generation rate
Solution Approach 1:
The patent changes the material parameter from rigid metal to elastic spring board, which can dynamically adjust its compression force. The spring board maintains sufficient compression force throughout its service life by utilizing elastic deformation rather than plastic deformation, thereby resolving the contradiction between initial force and duration of action.
Solution Approach 2:
The spring board introduces dynamic characteristics to the fastening system. Instead of a static metal plate that deforms permanently, the spring board can dynamically adjust its compression force in response to changes in the anode electrocatalyst layer thickness and operational conditions, maintaining effective compression throughout the service life.
2Strength
If the thickness of the metal plate is increased to avoid deformation, then the in-plane strength is improved, but production costs and structural complexity increase
Solution Approach 1:
The patent changes the fundamental parameter of the pressing board from rigid metal to elastic spring board. This material parameter change eliminates the need for increased thickness or reinforcement structures, as the spring board inherently maintains its functional properties through elastic deformation without requiring complex geometric modifications.
3Productivity
If the anode electrocatalyst layer thickness is reduced to improve performance, then the ozone generation efficiency increases, but the metal plate cannot maintain sufficient pressure, causing contact loosening and reduced ozone generation rate
Solution Approach 1:
The spring board provides dynamic compression force that adapts to the thinner anode electrocatalyst layer. As the layer thins, the spring board maintains sufficient compression force through its elastic properties, ensuring continuous effective contact between the anode electrocatalyst layer and solid polymer electrolyte membrane, thereby maintaining high ozone generation rates.
Solution Approach 2:
The patent changes the compression force parameter from fixed (metal plate) to variable (spring board). This allows the compression force to automatically adjust to the reduced thickness of the anode electrocatalyst layer, maintaining optimal pressure for high ozone generation efficiency throughout the operational life.

AI summary
An electrolytic ozone cell anode spring fastening board structure includes a solid polymer electrolyte membrane (1), an anode electrocatalyst layer (2), a diffusion layer (3), frame body and support parts (5). A diffusion layer counterpiece (4) has one side attached to the diffusion layer (3), the other side of the diffusion layer counterpiece (4) equipped with a centered elevated step, which contacts the center of the convex side of a spherical spring board (6). In addition, the solid polymer electrolyte membrane (1), frame body and support parts (5), diffusion layer (3), diffusion layer counterpiece (4) and spring board (6) are held together by mechanical fastening means. It prevents a decrease in ozone generation rate in electrolytic ozone cell that can occur from the metal board deformation and thinning of the anode electrocatalyst layer. This will enable the cell to maintain stable fasten strength and good contact of the metal board and anode catalyst in long term operation, achieving stable electrolytic ozone generation rate and cell performance.
