Solution Overview
Problem
Pressure cookers face issues with the pot lid and pot body not being properly buckled, leading to decreased pressure-resistance strength and potential safety risks, including the risk of explosion.
Innovation Solution
The cooking device incorporates at least two first and second fool-proof structures, such as fool-proof ribs and notches, on the pot lid and pot body, ensuring precise alignment and stable connection through a one-to-one cooperation, with additional features like a position-limiting groove and float assembly to prevent improper rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pot lid and pot body are screwed together without proper buckling, then assembly is simple, but pressure-resistance strength decreases and safety is compromised
Solution Approach 1:
The fool-proof structures (ribs and notches) are pre-formed on the pot lid and pot body to guide and ensure proper buckling alignment before the screwing operation occurs. This preliminary alignment mechanism prevents improper assembly while maintaining ease of operation.
Solution Approach 2:
The fool-proof structures act as intermediary elements between the pot lid and pot body, mediating the connection process by ensuring proper alignment through rib-notch engagement before the final screwed-together state is achieved.
2Reliability
If fool-proof structures are added to ensure proper alignment, then safety and sealing are improved, but device complexity increases
Solution Approach 1:
The fool-proof alignment mechanism is segmented into separate rib structures on one component and corresponding notch structures on the other component. This segmentation allows for independent manufacturing and assembly while ensuring proper alignment, improving sealing safety without excessive complexity.
Solution Approach 2:
The fool-proof structures are implemented locally at specific engagement points rather than throughout the entire component surfaces. The ribs and notches are positioned only where alignment is needed, providing necessary safety while minimizing overall structural complexity.

AI summary
The present disclosure provides a cooking device (100). The cooking device (100) includes a pot lid assembly (10) and a pot body (20). The pot lid assembly (10) includes a pot lid (11). The pot lid (11) has a plurality of first pot teeth (111). At least two of the plurality of first pot teeth (111) are each formed with a first fool-proof structure (112). The pot body (20) has a plurality of second pot teeth (21). At least two of the plurality of second pot teeth (21) are each formed with a second fool-proof structure (22). The cooking device (100) is configured to enable the pot lid (11) to be buckled with the pot body (20) by using a one-to-one cooperation between at least two first fool-proof structures (112) and at least two second fool-proof structures (22). The above cooking device improves alignment accuracy of the pot lid (11) and the pot body (20) by providing the at least two first fool-proof structures (112) and the at least two second fool-proof structures (22). In this way, it is ensured that the pot lid (11) and the pot body (20) are screwed together in response to the pot lid (11) and the pot body (20) being buckled smoothly with each other. Further, safe sealing of the cooking device (100) is ensured, to avoid the risk of an explosion resulting from screwing of the cooking device (100) in response to the cooking device (100) being not buckled in place.
