Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If image acquisition is used to analyze indoor control requirements, then visual information can be obtained, but the analysis accuracy deteriorates due to environmental factors affecting image quality

Engineering Contradiction:
Improveindoor control requirements informationVSAvoidanalysis accuracy
Core Design Contradiction:
Loss of informationVSMeasurement precision

Solution Approach 1:

The patent introduces UWB radar sensors as an intermediary device to detect indoor conditions. Instead of directly using image acquisition which is affected by environmental factors, the radar sensors detect object positions, movements, and physiological signals (heart rate, respiration) through electromagnetic waves, providing accurate information about indoor control requirements without being influenced by lighting or visual environmental conditions.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If gas monitoring is used to determine indoor control requirements, then air quality information can be obtained, but the measurement accuracy deteriorates due to gas environment interference

Engineering Contradiction:
Improveindoor control requirements informationVSAvoidgas concentration measurement accuracy
Core Design Contradiction:
Loss of informationVSMeasurement precision

Solution Approach 1:

The patent uses UWB radar sensors as an intermediary to detect indoor conditions through electromagnetic wave reflection from objects and their physiological signals. This approach provides accurate information about occupancy and activity levels without being susceptible to gas environment interference, unlike direct gas monitoring methods.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If preset schedules and fixed parameters are used for HVAC operation, then system operation is simplified, but energy efficiency deteriorates due to inability to adapt to actual demands

Engineering Contradiction:
ImproveHVAC system operationVSAvoidenergy waste
Core Design Contradiction:
Ease of operationVSLoss of energy

Solution Approach 1:

The patent implements dynamic adjustment of HVAC system parameters based on real-time detection data from UWB radar sensors. The system continuously monitors object positions, movements, and physiological signals, and automatically adjusts temperature, humidity, and ventilation parameters according to actual occupancy and activity levels, replacing static preset schedules with adaptive dynamic control.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent establishes a feedback loop where UWB radar sensors continuously detect indoor conditions (object presence, movement, physiological signals), the system processes this information to determine actual demands, and then adjusts HVAC operational parameters accordingly. This closed-loop feedback mechanism ensures energy efficiency by matching system output to actual requirements.

Inventive Principle:
Principle #23Feedback
