Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hydrogen peroxide solution is sprayed directly to the space, then decontamination is achieved, but the distribution is uneven and condensation occurs causing corrosion and explosion risks
Solution Approach 1:
The patent changes the physical state of hydrogen peroxide from liquid to vapor phase through controlled heating and evaporation. By adjusting temperature parameters and using a vaporizer system, the H2O2 is converted to gas form that distributes uniformly without condensing on surfaces, eliminating the harmful liquid accumulation effects while maintaining decontamination effectiveness
Solution Approach 2:
The patent replaces the mechanical spray system with a thermal vaporization system. Instead of using pumps and nozzles to force liquid H2O2 onto surfaces, the system uses heating elements to evaporate H2O2 into gas form, which then disperses naturally through the space, eliminating the condensation and corrosion problems associated with liquid application
2Device complexity
If a planar evaporator surface is used, then the structure is simple, but liquid flows too fast causing uneven evaporation and insufficient decontamination
Solution Approach 1:
The patent replaces the planar evaporator surface with a meandering groove structure that creates multiple curved pathways for liquid flow. The grooves slow down the liquid flow velocity and distribute it evenly across the evaporator surface, ensuring uniform evaporation rates while maintaining a relatively simple overall device structure
Solution Approach 2:
The patent divides the evaporator surface into multiple segmented grooves instead of using a single planar surface. This segmentation creates multiple flow channels that distribute the H2O2 liquid evenly, preventing rapid flow accumulation and ensuring consistent evaporation across the entire surface area
3Productivity
If the evaporator area is increased to improve vaporization, then more H2O2 can be vaporized, but the device size and complexity increase
Solution Approach 1:
The patent transitions from a two-dimensional planar evaporator surface to a three-dimensional meandering groove structure. By utilizing vertical depth and creating winding pathways, the effective evaporation surface area is dramatically increased within the same horizontal footprint, boosting vaporization rate without proportionally increasing device size or complexity

Function Achieved in This Case
Enhances disinfection efficiency by ensuring uniform distribution and preventing condensation, making it safer and more effective for larger spaces without the risks associated with liquid accumulation.
Implementation Method 1
an evaporator element (10), having a heating element (13), the heat of which can be directed to an upper surface of the evaporator element (10)
Implementation Method 2
the heat of which can be directed to an upper surface of the evaporator element (10)
Implementation Method 3
a meandering groove (11) with one or several branches for a liquid containing hydrogen peroxide, said groove (11) having a desired constant or varying width and depth, and in which the area covered by the groove (11), viewed directly from above, covers at least 50% of the entire area of the evaporator element (10) viewed directly from above
Implementation Method 4
the evaporator element (10) can be placed either in an inclined angle or the bottom surface of the groove (11) is arranged with its plane falling along the path of the liquid so that the liquid containing hydrogen peroxide can be fed and drained to the starting point (14) of the groove at the first end of the evaporator element (10) as the liquid travels along the groove (11) towards the end point (15) of the groove at the opposite, second end of the evaporator element (10)

AI summary
An improved vaporizer part, such as an evaporator element of a disinfection device is for an aqueous solution of hydrogen peroxide. The evaporator element includes one, and/or a branching, meandering structure, in which the straight sections of the groove are joined by 180-degree meanders near edges of the evaporator element. An end pit with an overflow guard is for overflown liquid. Heating elements are used both in connection with the evaporator element to enhance evaporation and on the inner surfaces of the device to prevent condensation. An air blower creates desired vortices near the surface of the evaporator element. The air control element also makes the air flow more laminar. The actual travel of the liquid on the evaporator element functions gravitationally on an inclined surface, and the capillary effect increases the evaporating area of the liquid. A disinfection device includes the vaporizer part.
