Pneumatic Clamp Rotation Locking for Vibration Direction Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vibration testing devices require labor-intensive processes to change the vibration direction of the vibration generator, and hydraulic mechanisms used to restrict rotation can contaminate the test environment and increase power consumption.
Innovation Solution
A vibration testing device using a gas-pressure-operated clamp device with a first and second member, allowing or restricting the rotation of the vibration generator relative to the support frame, automated by controlling gas pressure, eliminating the need for manual fastening and reducing environmental contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple fastening members are used to fix the vibration generator to the support frame, then the rotation of the vibration generator is restricted, but the process of changing vibration direction becomes time-consuming and labor-intensive
Solution Approach 1:
The patent applies pneumatic clamps instead of mechanical fastening members to restrict the rotation of the vibration generator. The pneumatic clamps can be quickly activated and deactivated through air pressure control, enabling rapid switching between locked and unlocked states without manual attachment and detachment of multiple fastening members, thus resolving the contradiction between reliable rotation restriction and time-consuming direction changing.
2Adaptability or versatility
If fastening members are manually detached and attached to change vibration direction, then the vibration generator can be rotated, but the process requires significant labor and time
Solution Approach 1:
The pneumatic clamp system replaces manual fastening member operations with automated pneumatic control. The operator simply needs to activate or deactivate the pneumatic clamp through a control mechanism, significantly simplifying the operation while maintaining the ability to change vibration direction between vertical and horizontal orientations.
Solution Approach 2:
The pneumatic clamp system provides self-service functionality where the clamping and releasing actions are automatically executed through pneumatic pressure changes, eliminating the need for manual intervention in attaching and detaching fastening members, thus reducing operational complexity.
3Extent of automation
If hydraulic mechanisms are used to restrict rotation, then automation is achieved, but hydraulic fluid leakage can contaminate the test environment
Solution Approach 1:
The patent specifically chooses pneumatic (gas-based) clamps over hydraulic (liquid-based) mechanisms to achieve automation in rotation restriction while avoiding the harmful effect of fluid leakage. Compressed air or inert gas is used as the working medium, which does not contaminate the test environment if leaked, thus resolving the contradiction between automation and environmental cleanliness.
Solution Approach 2:
The pneumatic system uses compressed gas which, in the event of leakage, simply dissipates into the atmosphere without requiring cleanup or causing contamination. This approach treats the working fluid as essentially disposable and non-harmful, eliminating the environmental contamination issue associated with hydraulic fluids.

Implementation Method 1
a clamp device using gas as working fluid, the clamp device has a first member and a second member, and is configured to be switchable by the working fluid between an unlock state in which relative rotation of the first member and the second member is allowed and a lock state in which the relative rotation of the first member and the second member is restricted

AI summary
The vibration testing device includes a vibration generator having a rotary shaft rotatably supported on a support frame, and a clamp device using gas as working fluid. The clamp device has a first member and a second member, and is switchable by the working fluid between an unlock state in which relative rotation of the first member and the second member is allowed and a lock state in which the relative rotation is restricted. One of the first member or the second member is fixed to the support frame, and the other is fixed to the rotary shaft. The clamp device switches between the unlock state and the lock state to switch between allowing and restricting the rotation of the vibration generator relative to the support frame.
