Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cookware assembly is complex and prone to unintentional detachment of handles, posing a risk of injury due to unreliable attachment methods.
Innovation Solution
A handle attachment system using a clamping plate with outwardly and inwardly directed resilient surface sections at acute angles, ensuring a non-detachable connection by preventing the handle from being pulled off, enhanced by corrugated surfaces and specific recess designs for increased spring action and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to attach the handle part to the vessel part, then the connection is secure, but the assembly becomes complex and unintentional detachment can still occur
Solution Approach 1:
The coupling part is divided into a receptacle portion (receiving the handle) and a projection portion (extending into the handle), with resilient surface sections segmented into outwardly directed and inwardly directed sections. This segmentation allows each segment to perform specific functions: the outwardly directed sections press against the receptacle inner contour while inwardly directed sections press against the coupling part outer contour, creating reliable attachment without complex screw assemblies.
Solution Approach 2:
The resilient surface sections are designed to be elastically deformable, allowing dynamic adaptation during assembly and use. The spring action of these resilient sections enables them to continuously maintain pressing forces against the coupling surfaces, providing reliable connection while simplifying assembly through elastic deformation rather than rigid fastening.
2Ease of manufacture
If a simple attachment method is used, then assembly is easy, but the handle part may detach unintentionally during use
Solution Approach 1:
The resilient surface sections are designed with specific geometric parameters: outwardly directed sections at acute angles to the receptacle inner contour, and inwardly directed sections at acute angles to the coupling part outer contour. These parameter changes create mechanical interlocking through spring action, where the angled surfaces convert radial pressing forces into axial retention forces, preventing pull-off while maintaining simple assembly.
Solution Approach 2:
The coupling part combines a receptacle portion (typically plastic or non-heat-conducting material) with resilient surface sections that have elastic properties. This composite structure integrates the handle-retaining function into the coupling part itself, where the resilient sections provide both the simple attachment interface and the reliable retention through their elastic deformation characteristics.
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 solution provides a simple, secure, and reliable assembly of cookware handles, ensuring they remain attached during use, enhancing safety and ease of production while maintaining a strong connection.
Implementation Method 1
at least one outwardly directed resilient surface section, which is at an acute angle to the inner contour of the receptacle and at least one inwardly directed resilient surface section, which is directed at an acute angle to the outer contour of the coupling part
Implementation Method 2
the resilient surface sections are corrugated. This achieves a good spring action, which causes the surface sections to be continuously pressed against the inner contour of the receptacle or the outer contour of the coupling part
