Solution Overview

Problem

Existing gripping devices for kitchen utensils fail to securely immobilize the movable clamp in its adjusted closed position due to the pivoting of locking pins, leading to deviation or reduced effectiveness, especially under deformation or heavy loads.

Innovation Solution

The introduction of movable locking means that operate perpendicular to the longitudinal direction, transitioning between a release and blocking position through friction, ensuring the clamp is immobilized in its adjusted position without relying on pin penetration, and are positioned to maintain stability and secure the clamp by frictional pinching.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a locking pin is used to immobilize the movable clamp, then the clamp can be secured in the closed position, but the locking pin tends to pivot in the cavity leading to deviation or reduced effectiveness

Engineering Contradiction:
Improvelocking effectivenessVSAvoidclamp position stability
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The locking means are made movable between a release position and a blocking position, allowing them to dynamically adapt to the clamp's position while maintaining secure locking. This dynamic capability enables the locking means to follow the clamp's adjusted position without pivoting, resolving the contradiction between reliable locking and position stability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The locking means act as an intermediary element that mediates between the fixed member and the movable clamp. By being movably mounted on the gripping body, they provide a stable reference point that prevents direct pivoting contact, thus maintaining both locking effectiveness and position stability.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If the locking pin penetrates into a slot in the movable member, then the clamp can be immobilized, but the movable member must have a specific configuration that complicates its design

Engineering Contradiction:
Improveimmobilization securityVSAvoidmovable member configuration
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The locking function is segmented from the movable clamp member and placed in a separate locking means that is movably mounted on the gripping body. This segmentation allows the movable clamp to have a simpler, more universal configuration without slots or special features, while the locking means provides the immobilization function independently.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of having the movable clamp member with a slot that receives a fixed locking pin, the invention inverts the arrangement by having a movable locking means that actively engages with the clamp. This inversion simplifies the clamp's configuration while maintaining reliable immobilization.

Inventive Principle:
Principle #13The other way round (Inversion)

3Reliability

If the locking pin is deformed due to repeated requests, then the locking effectiveness is reduced, but increasing the pin's strength may complicate the design

Engineering Contradiction:
Improvelocking durabilityVSAvoidlocking means structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The locking means are designed to be movable rather than fixed, allowing them to flex and adapt to position adjustments without experiencing the same deformation issues as a rigid pin. This dynamic design enhances durability while maintaining a relatively simple structure.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The locking means can change their position parameter between release and blocking positions, allowing them to accommodate variations in clamp position without deformation. This parameter flexibility improves durability without requiring complex structural reinforcements.

Inventive Principle:
Principle #35Parameter changes

Function Achieved in This Case

The solution effectively prevents the movable clamp from deviating from its adjusted position, ensuring secure gripping and maintaining effectiveness even under heavy loads or deformations, by utilizing frictional immobilization that is independent of pin penetration and stable across various positions.

Implementation Method 1

locking means which are movable between a release position in which they do not hinder the movement of the movable member forming a clamp, and a blocking position in which they immobilize this member in its adjusted position closed by friction

AI summary

The invention relates to a grip device (1) comprising an element (5) that can be moved in relation to a fixed element (4) between an open position and a closed position in which the two elements are adapted in such a way as to grip a wall, means (7) for moving the mobile element (5) and adjusting the distance between the two elements (4, 5) in a closed position to the thickness of the gripped wall, and blocking means (19) which are adapted in such a way as to immobilise the mobile element (5) in the adjusted closed position. According to the invention, the blocking means (19) can be moved between a release position and a blocking position in which they frictionally immobilise the mobile element (5) in the adjusted closed position.
