Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing building automation systems require a multitude of precise sensors distributed throughout a building to measure physical quantities like temperature and humidity, leading to complex and costly installations, especially due to the need for accurate placement to avoid inaccurate readings.
Innovation Solution
Integrating sensors into control points, allowing data collection and correlation across multiple locations to determine average or total physical quantities, such as average temperature or total acoustic power, without the need for additional sensors, and using thermal and aeraulic models to analyze air flows and detect specific events like an ironing session, thereby improving measurement precision and reducing installation costs.

Engineering Contradiction Analysis
1Measurement precision
If a multitude of precise sensors are distributed throughout the building, then measurement precision is improved, but device complexity and installation cost increase
Solution Approach 1:
The patent combines multiple sensor types (temperature, humidity, luminosity, acoustics) into integrated control units that are already present in the building automation system. Instead of distributing separate sensors throughout the building, the system merges sensing functions into existing control points, thereby reducing device complexity while maintaining measurement precision through data correlation algorithms.
Solution Approach 2:
The control units in the patent serve multiple functions: they act as both control devices for building equipment and as measurement points for collecting environmental data. This multi-functionality eliminates the need for dedicated sensor installations, reducing overall system complexity while enabling comprehensive monitoring across multiple locations.
2Measurement precision
If sensors are precisely installed in each room, then measurement precision is improved, but ease of manufacture and installation deteriorate
Solution Approach 1:
By merging sensor functions into existing control units that are already installed in the building, the system eliminates the need for precise sensor installation in each room. The control units are positioned according to building automation requirements, not sensor optimization requirements, thereby simplifying installation while maintaining measurement quality through computational methods.
3Measurement precision
If additional sensors are distributed in the building, then measurement precision is improved, but loss of substance and cost increase
Solution Approach 1:
The patent makes existing control units serve dual purposes: controlling building equipment and measuring environmental parameters. This eliminates the need to manufacture and install additional sensor devices, thereby reducing material consumption and installation costs while achieving comprehensive building monitoring through intelligent data processing.
