Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users in process control systems face difficulties in locating and comparing curve shapes due to their complexity and the need to search through historical trends for diagnosis, problem-solving, and optimization, as existing methods are cumbersome and time-consuming.
Innovation Solution
A user terminal with a processor that allows users to manipulate points on a curve, changing its shape to match their needs, and apply the modified curve section as input for operations such as searching or simulation, enabling faster location and formation of desired curve shapes within the process control system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If users search through historical trends to locate desired curve shapes, then they can find existing curves, but the process is time-consuming and cumbersome
Solution Approach 1:
The system pre-processes and stores curve characteristics in a database, allowing users to query for specific curve shapes without manually searching through historical trends. This preliminary organization enables rapid retrieval of desired curve shapes based on specific criteria.
Solution Approach 2:
The system allows users to create idealized curve shapes that can be copied and applied directly, eliminating the need to search for existing curves. Users can define their own curve characteristics and reuse them across different operations.
2Manufacturing precision
If users manually adjust curve points to create desired shapes, then they can achieve precise curve configurations, but the effort required increases
Solution Approach 1:
Users can create an idealized curve shape once and copy it for repeated use. The system stores the curve definition and allows rapid duplication, eliminating the need to manually adjust points for each new curve while maintaining precise configuration.
Solution Approach 2:
The system allows users to define curve characteristics through parameters rather than manual point-by-point adjustment. By changing key parameters, users can generate precise curve shapes efficiently without the labor-intensive process of adjusting individual points.
3Quantity of substance
If the process control system contains complex multi-parameter trends, then it provides comprehensive data, but searching and comparing trends becomes difficult
Solution Approach 1:
The system segments complex multi-parameter trends into individual curve components that can be searched and compared independently. Each curve represents a specific parameter, allowing users to focus on individual trends without being overwhelmed by the complexity of the entire multi-parameter dataset.

AI summary
A user terminal for a process control system obtains a first curve of a detected physical quantity of a piece of process control equipment in the process control system, where the first curve includes points with values of the physical quantity at various time instances, provides at least one of the points in a section of the first curve as a manipulable point that a user can change, receives from the user a change of at least one of the manipulable points in the section, thereby changing the section of the first curve, and applies the changed section of the first curve as an input to an operation in the process control system.
