Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a mesh screen is used for odor filtration, then the device structure is simple, but the odor filtering effectiveness is insufficient
Solution Approach 1:
The patent employs an activated carbon filter medium with porous structure to capture cooking odors. The porous material provides large surface area for adsorption while maintaining air permeability, effectively resolving the contradiction between simple structure and effective odor filtration.
Solution Approach 2:
The invention uses a composite structure combining a support plate with activated carbon particles. This composite material approach enhances the filtering effectiveness by utilizing the adsorption properties of activated carbon while the support plate provides structural integrity, achieving better odor removal without excessive complexity.
2Object-affected harmful factors
If a rotatable diverter mechanism is added to divert air through the filtering element, then the odor filtration is improved, but the device complexity increases
Solution Approach 1:
The patent utilizes natural convection currents generated during cooking to drive air through the filter. The hot air rising from the pot automatically creates the airflow needed for odor filtration without requiring external motors, fans, or complex diverting mechanisms. This self-service approach maintains simplicity while achieving effective odor removal.
Solution Approach 2:
The invention replaces mechanical air diversion systems with thermal convection-driven airflow. Instead of using motors, fans, or complex mechanical diverters, the system relies on the natural buoyancy of hot air to create the necessary airflow through the filtering element, eliminating mechanical complexity.
3Productivity
If a forced venting system with a blower is implemented, then air flow through the filter is enhanced, but the device complexity and energy consumption increase
Solution Approach 1:
The patent replaces mechanical blowing systems with thermal convection. The heat from cooking naturally creates upward air currents that drive airflow through the filter, eliminating the need for blowers, motors, and associated control systems while maintaining adequate air flow rates for effective odor removal.
Solution Approach 2:
The invention exploits the phase transition and thermal convection associated with heating. As air is heated by the cooking process, it expands and rises, creating natural airflow through the filter. This thermal-driven flow mechanism achieves the required productivity without mechanical intervention.
4Object-affected harmful factors
If multiple disks with air holes are stacked, then the air filtration efficiency is improved, but the assembly complexity increases
Solution Approach 1:
The patent integrates the filter medium directly onto the lid structure, merging the filtering function with the existing lid component. This consolidation eliminates the need for separate stacked disks while maintaining effective filtration, thereby simplifying assembly and disassembly operations.
Solution Approach 2:
The lid structure serves multiple functions: it covers the pot, provides structural support for the filter, and facilitates easy assembly and disassembly. By making the lid multi-functional, the invention eliminates the need for separate components, simplifying the overall assembly while maintaining effective air filtration.

AI summary
An odor filtering lid assembly includes a lid that is positionable on a cooking pot and that has female threads which are integrated into a perimeter of the lid. A first disk has a plurality of first air holes each extending through the first disk to pass air through the first disk. The first disk has male threads integrated into the first disk which threadably engaging the female threads in the lid for removably attaching the first disk to the lid. An air filter is positioned against the first disk to filter odors from air passing through the air filter. A second disk has a plurality of second air holes each extending through the second disk to pass air through the second disk. The second disk is positionable against the first disk such that the air filter is positioned between the first disk and the second disk.
