Solution Overview
Problem
Existing control systems for ventilation and air quality management are limited by fixed sensors that cannot accurately detect temperature and air conditions at the location of people, leading to inefficient energy consumption and incorrect regulation due to individual operator influences and stationary infrastructure restrictions.
Innovation Solution
A mobile control device with integrated sensors that can communicate wirelessly using protocols like WLAN and Bluetooth, allowing it to detect the number of mobile devices and transform control data, enabling flexible operation and accurate comparison of actual values with setpoint values, while reducing the need for additional infrastructure and allowing for predictive control based on recorded logs and external data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If permanently installed sensors are used to detect air quality, then the sensor readings are stable and continuously available, but the sensors cannot determine the actual temperature and air conditions at the location of people present and restrict the arrangement of furnishings
Solution Approach 1:
The patent transitions from static permanently installed sensors to dynamic mobile control units that can be moved to different locations. The mobile control unit with integrated sensors (temperature, humidity, air quality) can be positioned at the location of people to accurately detect local environmental conditions, resolving the contradiction between measurement precision and the restriction on furnishings arrangement.
2Ease of operation
If ventilation and exhaust air devices are activated based on individual user sensitivities detected by mobile control units, then the system responds to user needs, but unnecessary energy is consumed as devices require time and energy to reach new settings
Solution Approach 1:
The patent implements a feedback mechanism where the mobile control unit continuously monitors environmental parameters (temperature, humidity, air quality) and compares them against threshold values. When thresholds are exceeded, the system activates ventilation devices. The feedback loop includes evaluating whether activation is necessary by comparing current conditions with historical data and predicting when ventilation will be needed, thereby reducing unnecessary energy consumption while maintaining user comfort.
Solution Approach 2:
The system performs preliminary actions by continuously monitoring environmental parameters and comparing them with threshold values before activation is needed. The control unit evaluates whether activation is necessary by analyzing current conditions and historical data, allowing the system to prepare for ventilation needs without immediately activating devices, thus avoiding unnecessary energy consumption.
3Device complexity
If a single stationary control unit is used to control ventilation systems, then the system structure is simple, but the actual indoor air quality is measured at only one stationary point which may be incorrect for the entire building or large room
Solution Approach 1:
The patent divides the control system into multiple independent mobile control units, each equipped with sensors for detecting local environmental conditions. Instead of one stationary control unit measuring at a single point, multiple mobile units can be distributed throughout the building or large room, allowing air quality to be measured at multiple locations simultaneously. This segmentation maintains relatively simple individual unit structures while achieving comprehensive spatial coverage and improved measurement precision.
