Detachable Grip Mechanism With Friction Locking for Wall Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing detachable grip devices for kitchen utensils fail to securely immobilize the mobile grip element in its closed adjusted position due to pivoting blocking pins or reduced efficiency from pin deformation under repeated use.
Innovation Solution
The detachable grip device employs mobile blocking means that transition between a releasing and blocking position using friction, ensuring the grip element is securely immobilized in its closed position by frictional engagement, independent of pin penetration and deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a blocking pin with steps is used to prevent pivoting, then the mobile element can be immobilized, but the adjustment precision is reduced to discrete positions only
Solution Approach 1:
The patent replaces the mechanical pin-with-steps blocking system with a friction-based blocking system. The blocking means uses friction surfaces that press against each other to immobilize the mobile element, eliminating the need for discrete steps while maintaining continuous adjustability. This substitution of the mechanical engagement mechanism with a friction-based mechanism resolves the contradiction between reliable immobilization and precise continuous adjustment.
Solution Approach 2:
The patent changes the blocking mechanism from a discrete positional system (pin with steps) to a continuous friction-based system. By varying the friction force through mobile blocking means that can engage at any position along the grip body, the system achieves continuous adjustment precision while maintaining reliable immobilization through friction control.
2Reliability
If a blocking pin penetrates a slot in the mobile element, then the element can be blocked, but the pin deforms under repeated use reducing blocking efficiency
Solution Approach 1:
The patent replaces the pin-penetration-blocking mechanism with a friction-based blocking mechanism. Instead of a pin physically penetrating and blocking a slot, the system uses friction surfaces that press against each other to create blocking force. This eliminates the deformation issue associated with repeated pin insertion and withdrawal, significantly improving the durability of the blocking means while maintaining reliable blocking efficiency.
Solution Approach 2:
The patent introduces friction as an intermediary mechanism between the blocking means and the mobile element. Rather than direct mechanical penetration, the friction force acts as a mediator to immobilize the mobile element. This intermediary friction-based approach avoids the direct mechanical stress and deformation that occurs with pin penetration, extending the service life of the blocking system.
3Reliability
If the blocking pin is mounted on the lever, then it can block the mobile element, but the pin pivots in the cavity causing the element to shift from its closed position
Solution Approach 1:
The patent replaces the pivoting pin mechanism with a friction-based blocking system that eliminates pivoting motion. The blocking means uses friction surfaces that maintain stable contact without rotational movement, preventing the mobile element from shifting away from its closed position. This substitution eliminates the instability caused by pin pivoting while maintaining reliable blocking.

Function Achieved in This Case
This solution effectively prevents the mobile grip element from shifting away from its closed position, maintaining secure grip even under load, and enhances the durability of the blocking mechanism by eliminating pin deformation issues.
Implementation Method 1
blocking means which have a mobile mounting on the grip body according to a direction of friction that is perpendicular to the longitudinal direction, between a releasing position in which they do not obstruct the movement of the mobile element that forms a grip, and a blocking position in which they immobilise this element in its closed adjusted position by friction

AI summary
A grip device has an element that can be moved in relation to fixed element between an open position and a closed position in which the two elements are adapted in such a way as to grip a wall, a displacement device which enables the displacement of the mobile element and the adjustment of the distance separating the two elements in a closed position to the thickness of the gripped wall, and a blocking device, which are adapted in such a way as to immobilize the mobile element in the adjusted closed position. The blocking device can be moved between a release position and a blocking position in which they immobilize the mobile element by friction in the adjusted closed position.
