Rotary Valve Trigger Assembly for Flexible Single-Drive Sequencing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rotary valve systems require multiple drives for sequential actuation of valves, lack flexibility in sequence changes, and do not allow for simultaneous activation of any number of valves without mechanical reconfiguration.
Innovation Solution
A drive triggering assembly within a rotary valve block that uses a single drive to activate any number of valves in any sequence, featuring a dual rotor mechanism with arbor fixing elements and actuating fingers to control valves individually or in groups, allowing for circular or linear arrangements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple drives are used for sequential actuation of valves, then the valve actuation sequence can be controlled, but the device complexity increases
Solution Approach 1:
The patent combines multiple valve actuation functions into a single drive mechanism. The rotary valve block with cam profiles integrates the actuation of multiple valves into one rotating component, eliminating the need for multiple separate drives while maintaining sequential control capability.
Solution Approach 2:
The single drive mechanism is designed to perform multiple functions by actuating different valves through various cam profiles on the same rotary block. This universal mechanism can control any number of valves in any sequence without requiring additional drives.
2Adaptability or versatility
If mechanical reconfiguration is used to change valve actuation sequences, then different sequences can be achieved, but the ease of operation decreases
Solution Approach 1:
The patent employs adjustable cam profiles on the rotary valve block that can be repositioned or reconfigured without mechanical reassembly. This dynamic adjustment capability allows different valve actuation sequences to be achieved simply by changing the cam positions, maintaining ease of operation while providing sequence versatility.
3Adaptability or versatility
If each valve has its own triggering mechanism, then each valve can be activated independently, but the device complexity increases
Solution Approach 1:
The patent segments the valve actuation function into individual cam profiles on a single rotary block. Each cam profile corresponds to one valve but all cams are integrated into one rotating mechanism, providing independent valve control without the complexity of multiple separate triggering mechanisms.
