Smart P&ID Generation Using Templates and Design Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current engineering design processes for piping and instrumentation diagrams (P&IDs) are manual, time-intensive, error-prone, and lack standardization, leading to inconsistencies and increased costs across projects.
Innovation Solution
A web-based application that auto-generates smart P&IDs using engineering design logic and templates, allowing users to input selections and auto-generate consistent and standardized drawings at their desktops, eliminating the need for manual drafting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual drafting methods are used, then flexibility in design modifications is maintained, but design cycle time and error rate increase significantly
Solution Approach 1:
The patent replaces manual mechanical drafting with an automated computer-based system that uses templates and parameters to generate P&IDs. The system automatically creates drawings from process data, eliminating manual drafting operations while maintaining design flexibility through digital modification capabilities.
Solution Approach 2:
The system allows design parameters to be changed centrally in a database, which automatically updates all related P&IDs. This parameter-driven approach enables rapid design modifications without manual redrawing, significantly reducing design cycle time while maintaining accuracy through consistent parameter propagation.
2Manufacturing precision
If manual drafting is used, then customization for each project is possible, but standardization and consistency across projects deteriorate
Solution Approach 1:
The patent implements pre-defined templates and standard symbols that are prepared in advance for common process equipment and configurations. These templates encode industry standards and best practices, ensuring consistent drawing quality across projects while reducing the complexity of creating drawings from scratch.
Solution Approach 2:
The system uses universal templates and parameter sets that can be applied across multiple projects and drawing types. A single template can serve multiple purposes (P&ID, PFD, other engineering drawings), ensuring standardization while adapting to specific project requirements through parameter customization.
3Productivity
If manual drafting is used, then detailed control over each drawing element is maintained, but productivity and output rate decrease
Solution Approach 1:
The patent segments the P&ID creation process into independent parameter definitions, template selections, and automated assembly components. Users define high-level parameters and select templates, while the system automatically assembles the detailed drawing elements, dramatically increasing productivity while maintaining control through the parameter-definition interface.
Solution Approach 2:
The system uses templates and reusable drawing blocks that can be copied and instantiated multiple times with different parameters. This copying mechanism allows rapid generation of multiple drawings from a single template definition, increasing productivity while maintaining ease of operation through simple parameter modification.

AI summary
A computer-implemented method for generating a piping and instrumentation diagram (P&ID) for a corporate entity may include presenting an initial page on a web based application. The method may also include obtaining, by the web based application, an input on the page. The method may further include validating, by the web based application, the input. The method may also include generating, by the web based application, the P&ID using the input after validating the input.
