Cooking pot lid
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cooking pot lids have complex structures to alleviate internal pressure, making them difficult to manufacture and clean, which leads to hygiene issues and ineffective prevention of food overflow during cooking.
Innovation Solution
A cooking pot lid with a body, handle, overflow prevention cap, and cover, where the handle includes a first opening for pressure relief and a second opening for easy cleaning, and the overflow prevention cap moves to relieve internal pressure while preventing food overflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex structure is used to alleviate internal pressure, then pressure relief function is improved, but device complexity increases and ease of manufacture deteriorates
Solution Approach 1:
The lid is divided into multiple functional components: a body portion, a separate cover portion, and an overflow prevention cap. This segmentation allows each component to perform its specific function independently while simplifying the overall structure compared to complex integrated designs.
Solution Approach 2:
The overflow prevention cap is extracted as a separate removable component from the lid structure. This allows the cap to be easily removed for cleaning and replacement, simplifying maintenance while maintaining the pressure relief function through the cover's through-hole.
2Reliability
If a complex structure is used to alleviate internal pressure, then pressure relief function is improved, but ease of manufacture deteriorates
Solution Approach 1:
By segmenting the lid into separate components (body, cover, cap), each part can be manufactured independently using standard molding or machining processes, avoiding the need for complex multi-step manufacturing required by integrated pressure relief structures.
Solution Approach 2:
The removable cap design allows it to be manufactured separately and attached to the lid, simplifying the manufacturing process. The cap can be produced using simple molding techniques and attached through basic fastening methods, reducing overall manufacturing complexity.
3Reliability
If a complex structure is used to alleviate internal pressure, then pressure relief function is improved, but ease of operation deteriorates
Solution Approach 1:
The segmented design with separate body, cover, and cap components allows each part to be easily removed and cleaned independently. The cap can be taken off to access and clean the first opening and internal surfaces, making maintenance simple and effective.
Solution Approach 2:
The removable cap is designed to be easily detached from the lid body, allowing users to access and clean the internal surfaces and openings. This extraction of the cap as a separate serviceable component greatly simplifies the cleaning process compared to fixed integrated structures.
4Ease of operation
If the overflow prevention cap is easily separated, then ease of operation is improved, but reliability deteriorates
Solution Approach 1:
The overflow prevention cap is nested within the handle structure, which provides a retaining environment. The cap can be easily removed when needed but is normally held in place by the handle's internal geometry, balancing ease of removal with secure retention during use.
Solution Approach 2:
The handle acts as an intermediary structure between the cap and the external environment. It provides a mounting structure that secures the cap during cooking while allowing easy removal when needed, mediating between the conflicting requirements of retention and ease of operation.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The new structure of the cooking pot lid simplifies manufacturing and cleaning, effectively prevents food overflow during cooking, and maintains hygiene by allowing easy separation and washing of components.
Implementation Method 1
the overflow prevention cap moves in an upward direction, thereby relieving the internal pressure
Implementation Method 2
having a through-hole for relieving an internal pressure
