Shared Sensor Ventilation System to Reduce Sensor Count
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing ventilation systems require multiple sensors for each ventilation device, leading to an increase in the number of sensors needed, which is inefficient and costly.
Innovation Solution
A ventilation system where a single sensor is shared among multiple devices, with a transmitter-receiver system that transmits the detection signal to control devices, allowing each device to be controlled based on the sensor's data, and a remote control that manages operation commands to optimize sensor usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sensor is provided for each ventilation device, then each device can independently detect air state, but the number of sensors increases
Solution Approach 1:
A single sensor is designed to serve multiple ventilation devices simultaneously. The sensor detects air state parameters and transmits this information to multiple control devices, allowing one sensor to perform the function that would otherwise require multiple sensors, thereby reducing the total number of sensors needed in the system.
Solution Approach 2:
The patent introduces a transmitter-receiver system as an intermediary between the sensor and multiple control devices. The transmitter receives detection signals from the sensor and transmits them to multiple receivers, each associated with different ventilation devices. This intermediary mechanism enables one sensor to control multiple devices without requiring direct connection to each device.
2Adaptability or versatility
If multiple sensors are installed, then each ventilation device has dedicated detection capability, but system complexity increases
Solution Approach 1:
The sensor and control system are designed with universal functionality to serve multiple ventilation devices. A single sensor configuration can monitor and control multiple devices through the transmitter-receiver network, eliminating the need for separate sensor installations for each device and thereby reducing system complexity.
Solution Approach 2:
The system implements a feedback mechanism where the sensor continuously monitors air state and transmits this information to control devices via the transmitter-receiver system. The control devices receive real-time detection signals and adjust their operation accordingly, maintaining independent detection capability without requiring multiple physical sensors.

AI summary
The ventilation system (S) includes a setting unit (63) for setting, from among a plurality of ventilation devices (20), a first ventilation device (20-o) to which a sensor (40, 40a) is to be attached, and a second ventilation device (20-s) with which a detection signal of the sensor (40, 40a) is to be shared, and a transmitter-receiver (64) configured to receive the detection signal of the sensor (40, 40a) and transmit the detection signal to a control device (50) of each of the first ventilation device (20-o) and the second ventilation device (20-s) set in the setting unit (63). Each of the control devices (50) controls an associated one of the ventilation devices (20) based on the detection signal transmitted from the transmitter-receiver (64).
