Gas Driven Motor Vane Shutter Mechanism Low Pressure Torque
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gas driven motors require high operating pressures and complex mechanical controls to achieve high torque, while simpler systems with low pressure delivery systems provide only low torque, necessitating a design that achieves high torque with a low gas pressure system.
Innovation Solution
A gas driven motor design featuring a housing with a circulation chamber and shutter chamber, a drive axle, a vane with a curved surface, and a shutter that rotates and pivots to allow gas flow, enabling high torque output with low pressure gas flow by optimizing the interaction between the vane and shutter to reduce friction and enhance efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If high gas pressure is used to drive the motor, then high torque is achieved, but the system complexity and operating pressure requirements increase
Solution Approach 1:
The motor is divided into distinct functional chambers (circulation chamber and shutter chamber) that separate the gas flow path and torque generation process, allowing low pressure gas to be efficiently converted to rotational motion through the vane-shutter interaction mechanism
Solution Approach 2:
The vane is designed with a curved surface that optimizes the interaction with the shutter, allowing the low pressure gas flow to effectively push the vane against the shutter and generate high torque through the curved geometry that maximizes force application
2Device complexity
If simple vane arrangements are used with low gas pressure, then system complexity is reduced, but torque output decreases
Solution Approach 1:
The vane and shutter are integrated into a single rotational mechanism where the vane is attached to the drive axle and the shutter pivots within the same circulation chamber, creating a combined system that generates high torque without requiring separate complex control mechanisms for gas intake and exhaust
Solution Approach 2:
The drive axle serves multiple functions: it rotates the vane to interact with the shutter, it supports the shutter pivot, and it transmits the generated torque to the load, eliminating the need for separate mechanisms for each function and reducing overall system complexity

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design achieves high torque output with low gas pressure, reducing friction and improving efficiency, making it suitable for high torque low pressure systems, potentially operating effectively at pressures below 100 p.s.i., 50 p.s.i., or 20 p.s.i., and adaptable for various sizes and configurations.
Implementation Method 1
the vane is configured to rotate through the circulation chamber along an axis of rotation in response to an application of a gas flow
Implementation Method 2
