Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current industrial process control systems lack the ability to accurately measure and calculate torque on non-cylindrical valve bodies, as existing methods rely on straightforward conversions from strain to torque that are not applicable to non-cylindrical features.
Innovation Solution
A bracket system with a strain gauge mounted on a non-cylindrical structure, such as a C-shaped bracket, which includes recesses and patterns of openings to enhance strain measurement, coupled with a microprocessor to convert strain data into torque values using customized equations based on the bracket's geometry and material properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a strain gauge is mounted on a cylindrical body for torque measurement, then the conversion from strain to torque is simple and straightforward using known equations, but this method cannot be applied to non-cylindrical valve bodies
Solution Approach 1:
The patent changes the geometric parameters of the mounting structure from cylindrical to non-cylindrical (C-shaped, L-shaped, or Z-shaped brackets) while maintaining the strain measurement capability. This allows the torque measurement system to adapt to different valve body geometries without relying on standard cylindrical conversion equations
Solution Approach 2:
The patent segments the torque measurement function from the valve body itself by introducing a separate bracket structure. This bracket can be mounted on various valve body types and provides a standardized platform for strain gauge installation, decoupling the measurement system from the specific valve geometry
2Adaptability or versatility
If a strain gauge is mounted on a non-cylindrical bracket to measure torque on non-cylindrical valve bodies, then adaptability to different valve geometries is achieved, but the conversion from strain to torque becomes complex and not currently available
Solution Approach 1:
The patent introduces a microprocessor-based control system as an intermediary that performs the complex strain-to-torque conversion calculations. This intermediary component handles the mathematical complexity of converting strain measurements from non-cylindrical brackets into accurate torque values, making the overall system usable despite the complex conversion requirements
Solution Approach 2:
The patent replaces manual or simplified mechanical conversion methods with an electronic computing system (microprocessor). This substitution enables complex real-time calculations of torque from strain measurements on non-cylindrical structures, providing accuracy that would be difficult to achieve through mechanical means alone
