Foldable Lid Handgrip With Hinged Locking Handle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handgrips for cooking vessel lids are bulky, increasing the overall size of cooking vessels and lacking a reliable safety mechanism to maintain the gripping element in an open position, potentially causing burns.
Innovation Solution
A compact handgrip design featuring a hinged handle that snaps onto a base element, allowing rotation from a folded to an open position using symmetrical pins and block teeth for secure grip and heat insulation, with materials like phenolic resin for the base and nylon for the handle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the handgrip portion is made voluminous to ensure safe gripping and heat insulation, then heat insulation capability is improved, but the overall bulk of the cooking vessel increases
Solution Approach 1:
The handgrip portion is designed to be foldable relative to the coupling portion, allowing it to transition between an extended gripping position and a retracted compact position. This dynamic configuration enables the handgrip to provide adequate heat insulation and gripping surface area when needed, while reducing the overall bulk of the cooking vessel when the grip is not in use.
Solution Approach 2:
The foldable handgrip design allows the gripping portion to be nested against or near the coupling portion when not in use, similar to nested dolls. This reduces the external dimensions of the knob while maintaining the functional volume of the handgrip when deployed, effectively solving the contradiction between insulation capability and overall bulk.
2Reliability
If a safety system is added to maintain the gripping element in open position, then user safety is improved, but manufacturing complexity increases
Solution Approach 1:
The knob design allows the user to manually position the foldable handgrip in either the gripping or compact configuration, and it remains stable in that position without requiring additional safety mechanisms. The user themselves performs the function of maintaining the gripping element in the desired position, eliminating the need for complex automatic safety systems.
Solution Approach 2:
The foldable handgrip provides inherent stability when positioned in the open gripping configuration due to its structural design and connection to the coupling portion. This partial mechanical stability reduces or eliminates the need for additional safety systems, achieving user safety without excessive complexity.
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 design provides a safe, easy-to-grip, and compact solution that reduces bulk, ensuring effective heat insulation and secure handling of cooking vessels while preventing burns.
Implementation Method 1
the base element (14) consists of a monolithic body, preferably manufactured with a thermosetting polymeric material, for example in phenolic resin
Implementation Method 2
The handle (16) is hinged with respect to the base element (14) and can rotate from a closed or folded configuration to an open configuration

AI summary
The invention describes a handgrip (10) for a cooking vessel, usable in particular as a knob of a lid (12). The handgrip (10) comprises a base element (14), able to be fixed to the lid (12) or to a wall of the cooking vessel, and a gripping element or handle (16), snap-coupled with such a base element (14). The gripping element or handle (16) is hinged with respect to the base element (14) and can rotate from a closed or folded configuration, in which such a gripping element or handle (16) rests on the base element (14) in order to allow the handgrip (10) to reduce its own size in height, to an open configuration, in which such a gripping element or handle (16) is raised according to a right angle with respect to the base element (14) and can be gripped in order to raise the lid (12) or the cooking vessel on which the handgrip (10) is applied.
