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

VSEngineering 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

Engineering Contradiction:
Improvehandle fixingVSAvoidhandle compatibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

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.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

Engineering Contradiction:
Improvehandle compatibilityVSAvoidproduction automation
Core Design Contradiction:
Adaptability or versatilityVSExtent of automation

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

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.

Inventive Principle:
Principle #35Parameter changes

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

Engineering Contradiction:
Improvehandle standardizationVSAvoidrivet arrangement
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
