Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If HVAC systems operate based on traditional control methods, then the system structure is simple, but the temperature control precision is poor and energy efficiency is low
Solution Approach 1:
The patent replaces traditional mechanical temperature sensing and control mechanisms with vision-based thermal imaging technology. The thermal camera captures infrared radiation to generate temperature maps, substituting contact-based sensors with non-contact optical measurement, thereby improving measurement precision while enabling more sophisticated control algorithms
Solution Approach 2:
The patent introduces an image analysis module as an intermediary between the thermal camera and the HVAC control system. This module processes thermal images to extract temperature data, identifies occupied zones, and translates visual information into control parameters, bridging the gap between optical measurement and mechanical control
2Loss of energy
If HVAC systems continuously operate to maintain temperature, then thermal comfort is maintained, but energy consumption increases
Solution Approach 1:
The patent implements dynamic HVAC control by continuously capturing thermal images and updating temperature maps in real-time. The system adapts cooling/heating strategies based on changing occupancy patterns and thermal conditions, transitioning from static continuous operation to dynamic demand-based operation that maintains comfort while reducing energy waste
Solution Approach 2:
The patent uses thermal imaging to detect occupancy and thermal conditions in advance, allowing the HVAC system to pre-adjust temperatures in occupied zones before discomfort occurs. This predictive approach enables proactive temperature management rather than reactive continuous operation
3Difficulty of detecting and measuring
If traditional temperature sensors are used, then the device complexity is low, but the ability to detect occupancy and thermal conditions is insufficient
Solution Approach 1:
The patent employs a thermal camera that serves multiple functions: it acts as both a temperature measurement device and an occupancy detection system. The same optical sensor captures thermal radiation to generate temperature maps while simultaneously identifying occupied zones through heat signature analysis, eliminating the need for separate sensors and reducing overall system complexity despite enhanced capabilities
