Engineering Contradiction Analysis
1Productivity
If traditional manual methods are used to determine HVAC layout and wiring estimation, then the process can be performed with simple tools, but the process becomes difficult, costly, and time-consuming
Solution Approach 1:
The patent replaces manual mechanical methods with an automated computing system that uses software algorithms to process building information models and generate HVAC layouts and wiring estimations automatically, eliminating the need for manual calculations and drawings
Solution Approach 2:
The system creates digital copies of building information models and pre-engineering tools to process and analyze data, generating virtual representations of HVAC layouts and wiring paths without requiring physical field measurements or manual drafting
2Measurement precision
If traditional methods are used for determining HVAC layout and wiring, then the initial cost estimation can be obtained quickly, but the accuracy of the estimation becomes inaccurate and wrong
Solution Approach 1:
The system incorporates feedback mechanisms that allow it to process building information models and pre-engineering tools, compare generated layouts against building constraints, and iteratively refine wiring estimations to ensure accuracy while maintaining efficient processing time
Solution Approach 2:
The system performs preliminary processing of building information models and pre-engineering tools before generating final HVAC layouts and wiring estimations, ensuring that all constraints and requirements are accounted for in advance to improve accuracy
3Reliability
If manual determination methods are used, then the process remains simple and low-cost, but the initial estimated cost differs from the actual implementation cost
Solution Approach 1:
The patent replaces manual cost estimation with automated computing systems that process building information models to calculate precise material requirements, labor costs, and implementation timelines, ensuring that estimated costs accurately reflect actual implementation requirements
