Oscillating Cylinder Arm Structure for Turning Point Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oscillating cylinder control systems require complex adjustments of wafers or elements attached to the piston arm, necessitating tools and stopping the cylinder for precise positioning, which is cumbersome and inefficient.
Innovation Solution
A new arm structure with a moveable contact element that opens the pressure relieving channel of the impulse valve, allowing for easy adjustment of the turning points without needing to transfer wafers or stop the cylinder, using a screw that can be turned even when the piston is moving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If wafers are transferred to adjust the turning points of the piston arm, then the adjustment precision is improved, but the device complexity and operation time increase
Solution Approach 1:
The patent removes the wafer element from the adjustment mechanism and replaces it with a direct screw-threaded connection between the piston arm and the impulse valve arm. This extraction of the intermediate wafer component simplifies the overall structure while maintaining adjustment precision through the screw mechanism's inherent fine-positioning capability.
Solution Approach 2:
The screw mechanism serves multiple functions: it provides both the adjustment capability for turning point positioning and the mechanical connection between the piston arm and impulse valve arm. This multi-functionality eliminates the need for separate wafer components and locking mechanisms, reducing device complexity.
2Measurement precision
If tools are used to transfer and lock wafers during adjustment, then the adjustment precision is improved, but the ease of operation deteriorates
Solution Approach 1:
The screw mechanism is designed to be manually adjustable without requiring external tools. The operator can directly turn the screw to adjust the turning points and use the integrated locking feature to secure the position, making the system self-sufficient for adjustment operations.
Solution Approach 2:
The adjustment mechanism is segmented into distinct functional elements: the screw for fine adjustment and the integrated locking feature for securing the position. This segmentation allows each component to perform its specific function efficiently without requiring complex tooling.
3Measurement precision
If the cylinder is stopped during wafer adjustment, then the adjustment precision is improved, but the productivity decreases
Solution Approach 1:
The patent enables adjustment operations to be performed while the cylinder is in motion. The screw mechanism and impulse valve are positioned and designed to allow adjustment without requiring the cylinder to stop, making the system dynamic rather than static during adjustment operations.
Solution Approach 2:
The adjustment mechanism is pre-positioned such that the screw and impulse valve are accessible and can be adjusted without interrupting the cylinder's operational cycle. This preliminary positioning allows adjustments to be made as part of the normal operation rather than requiring separate stopping and adjustment phases.
4Speed
If the arm is located very close to the impulse valve for mechanical exploration, then the response speed is improved, but the ease of operation deteriorates due to limited access
Solution Approach 1:
The patent positions the screw adjustment mechanism in a different spatial dimension or orientation that is accessible from the front or side of the cylinder assembly. This dimensional repositioning allows the operator to access and adjust the screw without interference from the narrow space between impulse valves, while the arm remains closely positioned to the impulse valve for rapid response.

AI summary
An arm structure intended for controlling the impulse valve (5) of the oscillating cylinder which performs a back and forth movement whereupon the oscillating cylinder comprises a cylinder body ( 14), a cylinder chamber (1) formed into the mentioned body, a piston (2) which can be moved in the cylinder chamber with the help of a pressure media, feeding channels (15, 16, 17) of the pressure media to the cylinder chamber (1) and control devices in order to direct the pressure media to the cylinder chamber to various sides of the piston and away from the cylinder chamber in order to achieve a back and forth movement for the piston and whereupon the impulse valves (5) belong to the control devices the operation of which at least one arm (10); (12), which explores mechanically the position of the piston arm (7) the movement of which arm is adjusted to open the pressure relieving channel of the impulse valve (5). The contact element which can be moved in relation to the arm, is adjusted to the arm which contact element opens the mentioned pressure relieving channel.
