Removable handle, particularly for cooking containers for food
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing removable handles for cooking containers are complex to manufacture and use, have low durability due to intricate coupling systems, and are not easily adaptable to standard market containers, making them unsafe and economically inefficient.
Innovation Solution
A simplified removable handle design with a reduced number of components, featuring a base portion, handle portion, and a locking and unlocking lever with reliefs and an elastically deformable portion for secure attachment to cooking vessels, allowing easy assembly and use on various containers without requiring modifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex coupling and uncoupling systems are used in removable handles, then the handle can be securely attached to cooking containers, but the manufacturing complexity and number of components increase significantly
Solution Approach 1:
The patent merges the coupling body and uncoupling mechanism into a single integrated base portion. The resilient arm with latch finger combines the functions of securing and releasing the handle in one component, eliminating the need for separate coupling mechanisms and reducing the total number of parts while maintaining secure attachment.
Solution Approach 2:
The base portion serves multiple functions: it provides the coupling interface, contains the resilient arm for latching, and incorporates the uncoupling button mechanism. This multi-functional design reduces component count while ensuring reliable attachment and easy release of the handle from cooking containers.
2Reliability
If multiple components are assembled in the coupling system, then secure attachment is achieved, but the durability decreases due to weaker components
Solution Approach 1:
By combining the coupling body and uncoupling mechanism into a single molded base portion, the patent eliminates weak points between multiple assembled components. The integrated design ensures uniform material properties throughout the coupling system, improving durability and resistance to damage while maintaining secure attachment functionality.
3Reliability
If specialized attachment means are constructed for the handle, then secure coupling is achieved, but the adaptability to standard market containers is reduced
Solution Approach 1:
The base portion is designed with a universal coupling interface that can attach to various cooking container types. The resilient arm with latch finger provides a standardized attachment mechanism that works with different container shapes and materials, enhancing versatility while ensuring secure coupling across multiple applications.
