Cooking Vessel Sensor Conduit Design for Single-Piece Deep Drawing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooking devices with sensor conduits have a narrow radius between the base and the side wall, making it impossible to manufacture the vessel in one piece by forming or deep drawing without buckling the sensor conduit, rendering the device unusable for sensor arrangement.
Innovation Solution
A cooking device with a multi-layer base and side wall, featuring a vessel sensor conduit that extends from the connecting arrangement to the base, with a large radius in the transition area allowing for single-piece production by deep drawing, and enabling sensor insertion without buckling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the radius in the transition area is kept narrow as in prior art, then the device complexity is reduced, but the sensor conduit buckles during forming making the device unusable
Solution Approach 1:
The patent changes the geometric parameter of the transition area radius from narrow (prior art) to large (at least 19 mm). This parameter change allows the sensor conduit to maintain its shape during deep drawing forming without buckling, while still enabling single-piece manufacturing. The larger radius provides sufficient space for the conduit to follow the contour of the formed vessel base.
2Productivity
If the vessel is produced from multiple workpieces as in prior art, then the manufacturing precision requirements are reduced, but the production time and resource consumption increase
Solution Approach 1:
The patent merges the base and side wall into a single workpiece structure that can be formed in one deep drawing operation. The vessel is produced from a single plate body without requiring assembly of multiple components. This merging eliminates production steps, reduces resource consumption, and improves efficiency while the large transition radius ensures the sensor conduit survives the forming process.
3Loss of substance
If the vessel is produced from a single workpiece, then the resource consumption is reduced, but the forming process requires a large transition radius that complicates the vessel structure
Solution Approach 1:
The patent modifies the geometric parameter of the transition area radius to be at least 19 mm, which is sufficiently large to allow single-piece deep drawing forming without buckling the sensor conduit. This parameter change enables material-efficient single-workpiece production while the resulting geometry, though modified, remains functionally acceptable for the cooking device.
