Kitchen Vessel Lock Device Using Vacuum Pressure to Prevent Rattling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lock devices for kitchen vessels fail to completely secure them during transport, leading to rattling noise and potential damage to non-stick coatings due to movement between vessels.
Innovation Solution
A lock device with a lid and sealing ring made of elastically deformable material, featuring a check valve to create a pressure differential that locks the first vessel inside the second, preventing any movement, and a handle for easy removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vessels are secured using strings or retainers, then the vessels can be fastened together, but the vessels cannot be completely secured and will still move during transport
Solution Approach 1:
The patent employs a vacuum locking mechanism where air is extracted from the interior of the nested vessels, creating a pressure differential that firmly secures the inner vessel to the outer vessel. This pneumatic approach achieves complete securing reliability without complex mechanical fasteners, as the vacuum pressure naturally prevents any movement between vessels during transport.
2Object-affected harmful factors
If vessels are secured with traditional methods, then some movement is prevented, but rattling noise and damage to non-stick coatings still occur
Solution Approach 1:
By creating a vacuum environment between the nested vessels, the pressure differential firmly bonds the vessels together, completely eliminating any relative movement. This prevents both rattling noise and damage to non-stick coatings that occur with traditional fastening methods, while maintaining simple device structure.
3Reliability
If a sealing ring is used to create airtightness, then air can be extracted to create vacuum locking, but the sealing ring material must be elastically deformable to fit properly
Solution Approach 1:
The sealing ring is made of elastically deformable material that can flex to conform to the contours of the vessel openings, ensuring proper fit and airtight sealing. This flexibility allows the sealing ring to adapt to slight variations in vessel dimensions while maintaining the vacuum seal necessary for reliable locking.
Applied Scientific Principles
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 device ensures complete silence and protection of non-stick coatings by maintaining the vessels in a fixed position during transport, extending their useful life.
Implementation Method 1
the pressure difference between the interior of the vessels and the outside locks the lid on the first vessel
Implementation Method 2
a sealing ring made of an elastically deformable material. This sealing ring is placed at least on the outer edge of the lid, to allow the lid to fit into the second vessel and provide airtightness between the sealing ring and an inner wall of the second vessel. The elastic deformability causes the sealing ring to be pressed on the wall and prevents the passage of air.
