Cooking vessel provided with a handle fastened by two superposed rivets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooking containers with riveted handles require customized handle designs for each size, limiting standardization and making automated production challenging.
Innovation Solution
A cooking container design featuring a handle with an axial portion that is narrow enough (less than 30 mm wide) to be compatible with various sizes, allowing for standardized production and automated assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the axial portion has a significant width to accommodate two horizontally arranged rivets, then the handle fixing is improved, but the handle cannot be standardized across different cooking vessel sizes
Solution Approach 1:
The patent transitions from horizontal rivet arrangement to vertical stacking of rivets in superimposed horizontal planes. This dimensional change allows the axial portion width to be reduced to less than 30 mm while maintaining reliable handle fixing through the vertical distribution of rivets at different heights, enabling handle standardization across different cooking vessel sizes.
Solution Approach 2:
By standardizing the handle design with a narrow axial portion and vertically stacked rivets, the same handle can be universally applied to multiple cooking vessel sizes within a range, eliminating the need for size-specific handle variants and enabling automated production.
2Adaptability or versatility
If customized handle designs are created for each cooking vessel size, then the handle compatibility is improved, but the production automation is limited
Solution Approach 1:
The standardized handle design with narrow axial portion and vertically arranged rivets serves multiple cooking vessel sizes within a product range, enabling automated assembly lines to produce handles for different sized vessels using the same components and processes.
Solution Approach 2:
The invention changes the rivet arrangement parameters from horizontal to vertical stacking, and reduces the axial portion width to a standardized dimension less than 30 mm, allowing the same handle design to fit various cooking vessel sizes while maintaining compatibility.
3Adaptability or versatility
If the axial portion width is reduced to less than 30 mm, then the handle standardization is achieved, but the rivet arrangement becomes more complex
Solution Approach 1:
The patent resolves the complexity issue by moving rivets from a horizontal arrangement to vertical stacking in superimposed horizontal planes. This dimensional reorganization allows the narrow axial portion width of less than 30 mm while simplifying the overall design through standardized vertical positioning of rivets.
