Pressure Regulator Mechanism for Variable Workpiece Weights
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing regulator units are not adaptable for workpieces with varying weights, as they require reconfiguration when the weight changes, limiting their use with different loads.
Innovation Solution
A regulator unit with a pressure control mechanism that includes a cylindrical housing, a control spring, a collar-provided nut, and an operation handle, allowing for adjustable pressure settings and automatic return to a center position, enabling operation beyond the initial set range to accommodate workpieces with greater weights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a stopper is used to regulate the operation handle's turning range, then the regulator unit can maintain a set pressure for a specific workpiece weight, but it cannot be used for workpieces with different weights
Solution Approach 1:
The invention replaces the fixed stopper mechanism with a dynamic adjustment system. The operation handle's turning range is no longer fixed but can be adjusted according to different workpiece weights. The second stopper can be repositioned along the operation handle's rotation path, allowing the system to adapt to various weight requirements while maintaining reliable pressure control for each specific application.
2Reliability
If the operation handle's turning range is limited by a stopper, then the pressure setting is stable for one weight, but the operator cannot quickly position or stop the workpiece at desired positions
Solution Approach 1:
The system transitions from a static, fixed-range operation handle to a dynamic system where the operation range can be adjusted. The second stopper's repositionable nature allows the operator to expand or contract the available turning range based on the specific task, enabling both stable pressure control and flexible positioning operations.
Solution Approach 2:
The invention changes the parameter of operation handle rotation range from a fixed value to an adjustable value. By allowing the second stopper to be repositioned, the system modifies the operational parameters to match different work requirements, enabling the operator to achieve both stability and flexibility as needed.
3Speed
If a cylinder pressure control unit with multiple parts is used to control fluid pressure, then the raise/lower speed can be kept constant, but the device becomes large in size and has a complicated structure
Solution Approach 1:
The invention combines multiple functions into a single integrated regulator unit. The pressure control mechanism, operation handle, stoppers, and spring assembly are merged into one compact device that replaces what would traditionally require separate components. This integration maintains the ability to control raise/lower speed while reducing overall device complexity and size.
Solution Approach 2:
The regulator unit is designed as a multi-functional device that can perform pressure control, speed regulation, and positioning functions within a single compact structure. The operation handle serves multiple purposes: adjusting pressure, controlling flow rate, and positioning the workpiece, thereby eliminating the need for separate dedicated components for each function.

AI summary
Provided is a regulator unit that when a pressure is set with respect to a workpiece having a certain weight, can be used for raising/lowering, suspension, or the like of a workpiece having a weight exceeding the weight with the set pressure maintained. The regulator unit is disposed between a drive cylinder and a fluid pressure source and includes a regulator body and a pressure control mechanism connected to the regulator body. The pressure control mechanism includes a cylindrical housing, an end surface cover, and an operation handle fixed to an end of a screw rod protruding from the end surface cover. The end surface cover is fixed to a resin ring fitted to an end of the cylindrical housing and is slidingly rotatable with respect to the end surface of the cylindrical housing integrally with the resin ring in accordance with the amount of turn of the operation handle.
