Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual data collection and processing methods are used for HVAC system design, then detailed and accurate HVAC calculations can be performed, but the process becomes time-consuming and complex
Solution Approach 1:
The patent replaces manual mechanical data collection and calculation processes with automated electronic systems. Sensors automatically collect spatial and environmental data, while processors execute HVAC calculations algorithms, eliminating manual measurement and computation while maintaining accuracy.
Solution Approach 2:
The system performs self-service by automatically collecting data through sensors, processing information through integrated algorithms, and generating design proposals without requiring external manual intervention for each calculation step, thereby reducing time loss while preserving precision.
2Reliability
If comprehensive HVAC analysis is performed to determine suitable equipment size, type, and duct design, then reliable HVAC system design is achieved, but the process becomes complex and costly
Solution Approach 1:
The patent merges multiple separate design functions into a single integrated system. The same device that collects spatial data also performs HVAC analysis, equipment selection, and duct design calculations, consolidating previously separate complex processes into one unified workflow that maintains reliability while reducing overall complexity.
Solution Approach 2:
The system exhibits multi-functionality by performing spatial measurement, environmental sensing, HVAC load calculation, equipment selection, and duct design within a single platform. This universal approach ensures reliable comprehensive design without requiring multiple specialized tools or processes.
3Manufacturing precision
If traditional multi-device and multi-step processes are used for HVAC design, then thorough analysis is possible, but the process becomes costly and time-consuming
Solution Approach 1:
The patent substitutes traditional mechanical measurement tools and manual calculation methods with electronic sensors and automated processing. This replacement maintains design precision while dramatically improving productivity by eliminating repetitive manual tasks and enabling faster data collection and analysis.
4Productivity
If automated sensors and processing are used for HVAC design, then design speed and accuracy are improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple functional components (sensors, processors, display interfaces) into a single integrated device for HVAC design. This consolidation improves productivity by automating workflows while managing complexity through integration rather than multiplication of separate systems.

AI summary
Described herein are techniques for determining an HVAC system design for a space. The techniques makes the process of designing an HVAC system (e.g., for a contractor or engineer) more efficient by allowing a user to determine an HVAC system design for the space using a single device (e.g., a smartphone or table). The device obtains information about the space (e.g., boundary dimensions) and performs an HVAC analysis to determine HVAC system properties suitable for the space. The device determines an HVAC system design proposal for the space based on the determined HVAC system properties, and presents the design proposal to the user (e.g., in a GUI).
