Removable Handle Jaw Groove for Zero-Rotation Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handles for kitchen accessories suffer from rotary clearance along the longitudinal axis of the grip body, which can lead to instability and failure to securely clamp lateral walls of varying thicknesses.
Innovation Solution
The external jaw of the handle features a groove that receives the free end of the curved portion of the kitchen accessory's lateral wall in its closed position, creating three areas of contact: between the internal and external surfaces of the wall and the jaws, and between the curved portion and the groove, significantly reducing or eliminating rotary clearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the handle uses conventional two-jaw clamping structure, then the structure is simple, but rotary clearance exists along the longitudinal axis causing instability
Solution Approach 1:
The patent adds a groove feature to the external jaw that engages with the curved portion of the kitchen accessory, creating a third contact area that constrains rotation around the longitudinal axis. This dimensional addition transforms the clamping mechanism from purely linear (two jaws) to include rotational constraint (three contact points), eliminating rotary clearance while maintaining structural simplicity.
2Adaptability or versatility
If the handle clamps lateral walls of different thicknesses, then adaptability is improved, but rotary clearance increases causing instability
Solution Approach 1:
The groove in the external jaw is designed with specific dimensional parameters (depth, width, curvature) that allow it to engage with the curved portion of kitchen accessories of varying thicknesses. By optimizing these parameters, the handle maintains rotational constraint across different thicknesses, preventing rotary clearance while preserving adaptability to various accessory dimensions.

AI summary
Provided is a removable handle for a kitchen object, having a lateral wall extending upwardly by a part that is curved back towards the outside, the handle comprising an inner jaw and an outer jaw to be respectively brought against the inner and outer surfaces of the lateral wall, the two jaws being mobile in relation to each other between an open position and a closed position wherein they pinch the lateral wall. The outer jaw comprises a groove that can receive the free end of the curved part of the lateral wall in abutment when the jaws are in the closed position thereof.
