Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent makes mobile devices perform multiple functions: they serve as both user interaction interfaces and environmental sensing nodes. The mobile devices' built-in sensors (temperature, humidity, illuminance, sound, air quality) are utilized for environmental monitoring, eliminating the need for dedicated building sensors. This multi-functional approach reduces device complexity while maintaining measurement precision.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent leverages existing mobile devices that users already carry and use daily. These devices have their own built-in sensors and processing capabilities, so they can independently perform environmental sensing without requiring additional building infrastructure. The mobile devices serve themselves as both the sensing platform and the data processing unit, reducing overall system complexity.
