Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing removable gripping devices for culinary containers face challenges in securely clamping the side wall and pouring edge, especially under vertical stress, while maintaining manufacturing cost-effectiveness and minimizing damage to the container's coating.
Innovation Solution
A gripping device with a movable gripper member that inclines between 0° and 90° during translation, providing both horizontal and vertical clamping forces, and optionally incorporating a blocking member to immobilize the gripper, reduces the need for additional locking mechanisms and manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a blocking member is added to prevent separation of the movable gripper member, then reliability is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The movable gripper member automatically prevents its own separation through its inclined translation movement. The geometry of the movable member creates a self-locking effect where the inclined surface converts vertical lifting forces into clamping forces, eliminating the need for external blocking members and achieving reliability through self-service
Solution Approach 2:
The invention changes the movement parameter of the movable gripper member from horizontal to inclined translation. This parameter change creates a mechanical advantage where the inclined angle converts vertical forces into horizontal clamping forces, providing inherent stability without additional blocking components
2Reliability
If tightening force is increased to secure the culinary receptacle under vertical stress, then reliability is improved, but harmful factors increase due to coating damage
Solution Approach 1:
The invention changes the direction parameter of the gripper movement from horizontal to inclined. This creates a force decomposition where part of the tightening force is converted into a vertical component that actively resists lifting forces, providing better securing under vertical stress without requiring excessive clamping force that would damage the coating
Solution Approach 2:
The movable gripper member introduces a vertical dimension to its movement, translating not only horizontally but also vertically along an inclined path. This dimensional change allows the gripper to actively engage with vertical lifting forces, providing security against vertical stress while distributing the force more evenly to protect the coating
3Ease of manufacture
If the movable gripper member translates horizontally only, then ease of manufacture is improved, but adaptability to various container thicknesses and pouring edge clamping deteriorates
Solution Approach 1:
The invention modifies the movement parameter by introducing an inclined translation path for the movable gripper member. This single parameter change enables the gripper to adapt to various container thicknesses and effectively clamp the pouring edge, while maintaining manufacturing simplicity by using a straightforward inclined guide mechanism
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 inclined translation enhances clamping efficiency and adaptability to various container thicknesses, ensuring secure grip without excessive force, which reduces wear on the container's coating and lowers production costs by eliminating the need for a blocking member.
Implementation Method 1
the movable member is arranged to, when of the tightening of the gripper, to move in a direction of translation downwards forming with the normal to the support surface, in a plane median to the support surface and containing the said direction of translation, an angle of inclination included between 0 and 90°
Implementation Method 2
against the return action of an opening spring
Implementation Method 3
A compensation spring allows adjustment of the distance between the two gripper members in the clamping position to the thickness of the gripped wall
Implementation Method 4
The blocking member is mounted to move between a release position and a blocking position in which it immobilizes the movable gripper member by friction

AI summary
The removable gripping device for a cooking vessel comprises two members (3, 4) that form a clamp for clamping a wall of the cooking vessel (R), one of the members (4) being fixed and bearing a supporting surface (40) and the other member (3) being movable in translation between an open position and a closed position, said movable member comprising a downwardly angled end which forms one jaw of the clamp. According to the invention, the movable member (3) is designed so as to move, during the clamping of the clamp, in a downward translational direction (5) that forms an inclination angle (α) of between 0 and 90° with the normal (N) to the supporting surface (40) in a median plane with respect to the supporting surface (40) and containing said translational direction (5).
