Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing data collection systems for facility devices require the installation of a temperature sensor to control air temperature, which is inconvenient and may lead to erroneous operations due to heat permeation.
Innovation Solution
A data collection apparatus that estimates internal air temperature and controls it by using a ventilation device without the need for a temperature sensor, by employing a management device that calculates the estimated air temperature based on operation and meteorological data, and adjusts the ventilation accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a temperature sensor is installed in the data collection apparatus to control air temperature, then the air temperature control function is improved, but the device complexity and installation requirements increase
Solution Approach 1:
The patent introduces a heat transfer medium (air) as an intermediary to transmit temperature information from the internal environment to the external temperature sensor. The sensor is placed outside the sealed housing, and the air inside the housing acts as the medium that carries thermal information to the sensor through the housing structure, eliminating the need to install the sensor inside the apparatus.
Solution Approach 2:
The patent replaces the direct electrical connection method (installing sensor and interface inside the apparatus) with a thermal field-based method. By utilizing heat conduction through the housing and convection of air, the system substitutes the mechanical/electrical installation complexity with a thermal field approach that achieves the same temperature monitoring function.
2Measurement precision
If a temperature sensor and interface are installed in the data collection apparatus, then the temperature monitoring capability is improved, but the ease of operation and installation are worsened
Solution Approach 1:
The patent uses air as a thermal intermediary that naturally circulates between the internal components and the external environment. This air medium carries temperature information without requiring physical intervention or complex installation procedures, maintaining measurement capability while greatly simplifying operation.
Solution Approach 2:
The system utilizes the natural thermal convection and conduction properties of the housing and air to automatically transmit temperature information. No active control or complex installation is needed - the thermal field naturally performs the measurement function by itself, making the system self-sufficient and easy to operate.
3Reliability
If the data collection apparatus is sealed to protect internal devices, then the reliability is improved, but the temperature control capability is worsened due to heat permeation
Solution Approach 1:
The patent introduces air as a thermal intermediary that can pass through the sealed housing to carry temperature information. The housing remains sealed for protection, but the air medium enables thermal communication between the internal environment and external sensor, resolving the contradiction between sealing and temperature control.
Solution Approach 2:
The patent replaces the need for physical temperature sensor installation (mechanical/electrical system) with a thermal field-based measurement approach. The sealed housing is replaced as the measurement interface by using the air thermal field that naturally transmits temperature information through the housing structure.

AI summary
A management device estimates an air temperature inside a data collection apparatus as an estimated air temperature, based on operation data received from an air conditioner and meteorological data received from a server via a communication device. When the estimated air temperature is higher than an operable temperature of the communication device, the management device performs control to decrease the air temperature inside the data collection apparatus. When a ventilation-in-progress air temperature is higher than the operable temperature of the communication device, the management device transmits to a breaker device a command to stop the communication device, thereby decreasing the air temperature inside the data collection apparatus. When the ventilation-in-progress air temperature is lower than or equal to the operable temperature of the communication device, the management device transmits to the breaker device a command to run the ventilation device, thereby decreasing the air temperature inside the data collection apparatus.
