Venting for a combination cooking system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Combination cooking systems require complex venting arrangements to accommodate different cooking modes, such as convective and moist environments, which complicates the operation and increases costs.
Innovation Solution
A simplified venting mechanism that allows for adjustable vent positions and a removable seal between the lid and housing, enabling seamless transitions between various cooking modes by controlling airflow and humidity levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple vents and seals are used to accommodate different cooking modes, then the system can perform both dry and moist cooking operations, but the device complexity and cost increase
Solution Approach 1:
The single vent structure is designed to perform multiple functions by being configurable in different positions (open, closed, partially open) and by working in combination with an removable seal. This universal design eliminates the need for separate vents for different cooking modes, thereby reducing device complexity while maintaining cooking mode versatility.
Solution Approach 2:
The vent is designed as a dynamic component that can be adjusted between multiple positions (fully open, partially open, fully closed) rather than being a fixed structure. This dynamic adjustability allows the same vent to accommodate different airflow requirements for various cooking modes, resolving the contradiction between versatility and complexity.
2Adaptability or versatility
If multiple vents and seals are used to accommodate different cooking modes, then the system can perform both dry and moist cooking operations, but the manufacturing cost increases
Solution Approach 1:
By designing a single multi-functional vent structure that can serve different cooking modes through positional adjustment and combination with a removable seal, the manufacturing cost is reduced compared to producing multiple separate vents and sealing mechanisms. This universal component approach simplifies manufacturing while maintaining versatility.
Solution Approach 2:
The patent combines the functions of multiple vents into a single vent structure that can be configured for different cooking modes. This merging of functions reduces the total number of components that need to be manufactured, assembled, and maintained, thereby reducing manufacturing cost while preserving adaptability.
3Ease of operation
If the seal is removed to create an air gap for convective cooking, then air can flow freely for dry cooking modes, but moisture is retained when the seal is replaced for moist cooking modes
Solution Approach 1:
The seal is designed to be pre-installed or easily removable by the user before cooking begins, allowing simple transition between cooking modes. The preliminary positioning of the seal (either installed or removed) prepares the system for the intended cooking mode, making mode transitions straightforward while avoiding complex automated mechanisms.
Solution Approach 2:
The seal can be completely removed from the system when convective cooking is required, creating an open air gap without requiring complex mechanisms. This extraction of the sealing element simplifies the system for dry cooking modes while allowing moisture retention when the seal is present for moist cooking modes.

AI summary
A combination cooking system and methods for cooking having a simplified venting structure are provided. In one embodiment, the cooking system can include a housing having a hollow chamber for receiving food, a lid coupled to the housing for enclosing food within the chamber, and at least one heating element. In use, a seal disposed between the lid and housing can be selectively removed to create an air gap there between, thus providing a simplified method for venting air within the housing and thereby enabling the system to operate in different cooking modes. A locking element for locking the lid relative to the housing and/or an adjustable vent can also be selectively used to control venting within the system to enable the system to operate in different cooking modes.
