Clamping Device One-Handed Operation Automatic Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clamp devices are cumbersome and unsafe for operators, requiring both hands to open and close, and are prone to accidental release due to vibrations, posing risks to operators and equipment.
Innovation Solution
A clamp device design featuring a handle with a spur for single-handed operation, a locking mechanism with a spring-actuated catch element and stroke limiting means to ensure automatic locking in the closed position, preventing accidental release and allowing easy operation with one hand.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a safety lever with handle is used to lock/unlock the clamp device, then the device can be securely locked in closed position, but the operation becomes time-consuming and requires both hands
Solution Approach 1:
The patent combines the safety lever and coupling element into a single integrated locking mechanism. The safety lever is hinged to the base portion and works together with the coupling element to provide automatic locking when the clamp is closed, eliminating the need for separate manual locking operations.
Solution Approach 2:
The locking mechanism is designed to automatically lock when the clamp device is closed. The safety lever and coupling element engage automatically through the closing motion itself, without requiring additional manual intervention to activate the locking function.
2Reliability
If multiple components (handgrip, coupling element, safety lever) are used to ensure secure clamping, then the device can prevent accidental release under vibration, but the structure becomes more complex and operation more difficult
Solution Approach 1:
The patent merges the safety lever and coupling element into an integrated system where both components work together as a unified locking mechanism. The safety lever is hinged to the base portion and cooperates with the coupling element to provide automatic locking, reducing the need for separate independent locking components.
Solution Approach 2:
The coupling element serves multiple functions: it connects the handgrip to the base portion, provides the locking engagement surface for the safety lever, and enables the automatic locking mechanism. This multi-functionality reduces the overall number of components needed in the system.
3Reliability
If the operator must use both hands to operate the clamp device (one hand on handgrip, one on safety lever), then secure locking is achieved, but operator safety is reduced due to increased exposure time
Solution Approach 1:
The locking mechanism automatically engages when the clamp is closed. The safety lever and coupling element work together to provide automatic locking through the closing motion itself, eliminating the need for the operator to manually position and secure the safety lever with the second hand.
Solution Approach 2:
The automatic locking mechanism allows the operator to complete the closing and locking action in a single swift motion without pausing to manually engage separate components. This reduces the time the operator's hands are exposed to potential injury zones during operation.

Implementation Method 1
a spring configured so as to push the locking device into the locking position
Implementation Method 2
a handle rotatably hinged on the base by means of a pivot pin
Implementation Method 3
a hooking element hinged to the handle and to the base and designed to engage with a housing seat provided in the base

AI summary
A clamp device comprises a base on which is pivoted a handle which is rotatable about a pivot pin for opening and/or closing the clamp device, a closing device adapted to engage with a clamp element to close the clamp device in a closed configuration, and a locking device for locking the clamp device in the closed configuration hinged by a hinge pin to the handle so that it can be moved between a locking position, in which, in the closed configuration, a catch element of the locking device interacts with the base to attach the clamp device to the base, and a release position in which the handle is free to rotate relative to the base, the locking device comprises a stroke limiting device to limit the rotation of the locking device from the locking position.
