Adjustable Cooker Lid With Sealed and Vented Cooking Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current kitchen appliances that combine pressure cooking and air frying functions require separate lids, leading to cluttered storage due to the need for additional components, which defeats the purpose of a single appliance solution.
Innovation Solution
A single lid for a kitchen appliance that can be adjusted between pressure cooking and air frying modes using a dial and clamp mechanism, with a spring-biased seal plate to ensure airtightness for pressure cooking and airflow for air frying, eliminating the need for multiple lids.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two separate lids are used for pressure cooking and air frying functions, then both cooking functions can be performed, but storage space is consumed and clutter increases
Solution Approach 1:
The single lid is designed to perform multiple cooking functions (pressure cooking and air frying) through a dial mechanism that adjusts the lid's position and seal configuration, eliminating the need for separate specialized lids for each cooking mode
Solution Approach 2:
The lid incorporates a dial mechanism with multiple positions that dynamically adjusts the seal plate and clamp configuration to transition between pressure cooking (sealed) and air frying (vented) modes, allowing one lid to adapt to different cooking requirements
2Volume of stationary object
If a single lid is used for both pressure cooking and air frying, then storage space is saved, but the lid must be complex enough to perform both functions
Solution Approach 1:
The lid is segmented into functional components (clamp members, seal plate, dial mechanism, vents) that can be independently adjusted through the dial mechanism, allowing each component to serve its specific function while contributing to the overall multi-functionality of the single lid
3Reliability
If the lid is sealed for pressure cooking, then pressure cooking function is effective, but airflow is blocked for air frying
Solution Approach 1:
The seal plate and clamp mechanism are dynamically adjustable through the dial mechanism, allowing the lid to transition from a sealed configuration (for pressure cooking) to a vented configuration (for air frying), with the dial mechanism controlling the position of sealing elements and airflow passages

AI summary
The present invention provides a combination pressure cooker and air fryer lid that may be attached to a vessel. The lid may be adjustable between two general cooking positions. In the first cooking position, the lid may operate with the vessel as a pressure cooker. In the second cooking position, the may operate with the vessel as an air fryer. In performing either of the pressure cooking or air fryer cooking functions, the lid need not be replaced.
