Automated HVAC Control Panel Design System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional control panel redesign for HVAC equipment is time-consuming and expensive, limiting OEMs' ability to offer customers more options and faster turn-around times, and often results in the omission of accurate documentation, which complicates equipment servicing and troubleshooting.
Innovation Solution
A computerized system comprising a product-configuration module, a technical-design module, and a manufacturing module that simplifies the design and manufacturing process by receiving user inputs, generating as-built engineering drawings, component listings, and assembly instructions for robotic manufacturing, allowing for efficient production and documentation of custom control panels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional control panel redesign is performed manually for each custom HVAC configuration, then customization capability is improved, but design time and cost increase significantly
Solution Approach 1:
The system creates accurate digital copies (as-built drawings) automatically during the design process, eliminating the need for separate manual documentation and enabling rapid reproduction of control panel designs for similar configurations
Solution Approach 2:
The system uses parametric modeling where control panel designs are defined by configurable parameters. When customer selections change, the system automatically updates the design by changing these parameters rather than performing complete manual redesign, dramatically reducing design time while maintaining customization
2Adaptability or versatility
If conventional control panel redesign is performed manually, then design flexibility is improved, but manufacturing cost increases
Solution Approach 1:
The system replaces manual mechanical drafting and design processes with automated computer-based design software that generates manufacturing-ready drawings and documentation, reducing labor costs and improving accuracy
Solution Approach 2:
The system performs preliminary design work using standardized templates and pre-configured parameters. By preparing design frameworks in advance and automatically adapting them to customer specifications, the system reduces both design time and manufacturing costs while maintaining flexibility
3Loss of time
If documentation steps are skipped to reduce time, then turn-around time is improved, but serviceability deteriorates
Solution Approach 1:
The system automatically creates and stores accurate digital copies (as-built drawings) of each control panel design during the manufacturing process. These digital records enable easy servicing and troubleshooting without requiring time-consuming manual redrawing or physical inspection of the equipment
Solution Approach 2:
The system performs self-documentation automatically during the design and manufacturing process. By generating its own as-built drawings and technical documentation without requiring separate manual intervention, the system maintains complete serviceability information while keeping the process efficient

AI summary
The present inventors devised, among other things, systems, methods, and software that radically simplify and reduce the time necessary to specify, design, manufacture, and document control panels and wiring harnesses for semi-custom and custom equipment, such as HVAC equipment. One exemplary system includes a computerized product configuration module that defines product family parameters from user input and outputs a product family data structure, for example, a coded character string, to a technical design module. The technical design module, which incorporates engineering design rules for control panels and wiring modules, automatically processes the coded character string, outputting detailed engineering drawings, component listings, and even assembly instructions to robotic manufacturing equipment. The exemplary system dramatic reduces the product specification and engineering time required for any custom control panel and makes it possible for OEMs to efficiently offering more options and shorter turn-around times to its customers.
