Remote Gripper Clasp Locking Button to Prevent Mutual Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote-controlled gripper slings face issues with the button for opening the clasp and the unlocking button potentially blocking each other, leading to operational difficulties, especially when the button is hard to access.
Innovation Solution
A single button integrates both locking and drive functions, featuring a locking area that engages with the clasp in the closed position to prevent blocking, and includes a traction device for alternative actuation, allowing the clasp to be locked and opened securely without a separate unlocking button.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a button for opening the clasp and an opposite unlocking button are provided, then the clasp can be opened reliably, but the button and unlocking button can block each other causing operational failure
Solution Approach 1:
The invention extracts the blocking function from a separate component and integrates it into the button itself. The button is provided with a blocking area that can engage with the clasp to prevent mutual blocking between the opening button and unlocking button, thereby resolving the contradiction between reliable opening and operational ease.
2Device complexity
If the button is accessible from only one side of the stop means, then the device structure is simplified for one-armed operation, but the button may be difficult to access due to random positioning during operation
Solution Approach 1:
The invention provides the button with multi-functionality by equipping it with both a blocking area for preventing mutual blocking and a gear section for movement transmission. Additionally, the blocking area serves dual purposes: it locks the clasp in the closed position and prevents the button from being blocked by the unlocking button, thereby simplifying the structure while maintaining operational ease.
3Reliability
If the blocking area and gear section are integrated on a single button component, then mutual blocking is prevented, but the button mechanism becomes more complex
Solution Approach 1:
The invention merges the blocking function and the movement transmission function into a single button component. The blocking area and gear section are both provided on the button, eliminating the need for separate components and reducing overall device complexity while ensuring reliable prevention of mutual blocking.

AI summary
The invention relates to a stop means (1) for actuating by means of a remote-controlled gripping arm in particular of a remote-controlled vehicle using a single arm. The stop means (1) has a clasp (4) which can be moved from a closed position (5) into an open position (82), a stop element (2) which is closed in the closed position (5) of the clasp (4) and is open in the open position (82), and a pushbutton (18) for opening the clasp (4). The pushbutton (18) has a transmission section (68) which couples the clasp (4) to the pushbutton (18) so as to transmit a movement. The aim of the invention is to improve reliability during operation even under unfavorable conditions, for example in heavily polluted surroundings on the ocean floor. According to the invention, this is achieved in that the pushbutton (18) is provided with a blocking region (56) which is in engagement with the clasp (4) in the closed position (5) and locks the clasp (4) in the closed position (5).
