Solution Overview

Problem

Manual input of installation locations for a large number of facility devices and sensor devices in a building is labor-intensive for operators, increasing their workload.

Innovation Solution

A facility device management system that uses wireless communication between indoor units, ventilation devices, outside air cooling devices, temperature sensors, and CO2 sensors to automatically associate and manage these devices, reducing the need for manual input of installation locations by storing and managing device information and associations within a management apparatus.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual input method is used to register installation locations of facility devices and sensor devices, then installation location information can be accurately recorded in the management apparatus, but the operator's workload increases significantly

Engineering Contradiction:
Improveinstallation location information accuracyVSAvoidoperator workload
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The facility devices and sensor devices automatically perform the registration of their own installation location information by transmitting device identification information to the management apparatus, eliminating the need for manual operator input while ensuring accurate recording of installation locations

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The manual mechanical input process is replaced by an automated electronic communication system where facility devices and sensor devices transmit their identification information via wireless communication to the management apparatus, substituting human operation with automated digital transmission

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Quantity of substance

If manual input method is used for a large number of devices, then complete device registration can be achieved, but the time required for registration increases

Engineering Contradiction:
Improvenumber of registered devicesVSAvoidregistration time
Core Design Contradiction:
Quantity of substanceVSLoss of time

Solution Approach 1:

Each facility device and sensor device automatically transmits its own identification information to the management apparatus without requiring operator intervention, enabling rapid registration of large numbers of devices simultaneously

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The device identification information is transmitted automatically upon device installation or activation, performing the registration action preliminarily before any management operations are required, thus eliminating subsequent manual registration steps

Inventive Principle:
Principle #10Preliminary action

AI summary

A facility device management system (101) includes a plurality of facility devices, a management apparatus (100), and a sensor device. The plurality of facility devices include a first facility device (10a to 10i) having identification information. The management apparatus communicates with the facility devices via a network (90). The sensor device includes a wireless communication unit. The first facility device includes a receiving unit (16a to 16i) that receives data from the sensor device via wireless communication, and a transmitting unit (17a to 17i) that transmits the data, together with the identification information, to the management apparatus. The management apparatus (100) includes a storage unit (110). The management apparatus (100) associates the first facility device and the sensor device with each other based on information received from the first facility device, and stores an association between the first facility device and the data of the sensor device in the storage unit (110).
