Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing device registration systems for buildings face challenges in accurately identifying and registering position and unique information of devices at installation locations, often requiring manual intervention by workers, which is time-consuming and costly.
Innovation Solution
A device registration work assistance system comprising a management apparatus, indoor units with BLE communication capabilities, and a mobile terminal that estimates device arrangement based on electromagnetic waves, calculates candidates for each installation location, and notifies workers of unidentifiable devices, allowing efficient registration of only those that cannot be identified automatically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automatic device registration is performed using existing systems, then registration speed is improved, but identification accuracy deteriorates leading to incorrect device-position matching
Solution Approach 1:
The patent introduces a worker terminal as an intermediary between the automatic registration system and the final registration result. The terminal displays candidate device information to workers, who then confirm or correct the automatic matching results. This intermediary approach allows the system to benefit from both automatic speed and human verification accuracy.
Solution Approach 2:
The system implements feedback by having workers verify automatic registration results through the terminal interface. The worker's confirmation or correction feedback is used to validate or adjust the automatic matching, creating a closed-loop system that improves identification accuracy while maintaining registration efficiency.
2Measurement precision
If manual verification is performed for all device registrations, then identification accuracy is improved, but registration time increases
Solution Approach 1:
The patent applies partial verification by having workers review only the candidate device information presented by the system, rather than manually checking all devices from scratch. The system performs automatic pre-screening and presents limited candidates for verification, reducing the worker's burden while maintaining accuracy.
Solution Approach 2:
The system performs preliminary automatic matching of devices to installation locations before worker verification. This preliminary action filters and ranks candidate devices, so workers only need to verify the most likely matches rather than evaluating all possible combinations, significantly reducing registration time.
3Reliability
If workers visit all installation locations for registration, then complete coverage is achieved, but travel time and costs increase
Solution Approach 1:
The patent extracts the verification function from the worker's physical presence requirement. By displaying candidate information on portable terminals, the system allows workers to verify registrations remotely or at optimized locations, eliminating the need to physically visit every installation location and reducing travel time while maintaining registration completeness.
Solution Approach 2:
The worker terminal serves multiple functions: displaying candidate device information, receiving worker verification input, and communicating with the management apparatus. This multi-functional tool consolidates various registration tasks into a single device, improving workflow efficiency without compromising completeness.

Function Achieved in This Case
This system reduces the time and cost associated with device registration by enabling workers to focus on locations where identification is uncertain, ensuring accurate registration while minimizing unnecessary visits.
Implementation Method 1
The devices include a communication unit that performs wireless communication with each other
Implementation Method 2
The management apparatus estimates arrangement information of the devices based on information relating to electromagnetic waves acquired by the devices performing wireless communication with each other

AI summary
A device registration work assistance system includes a plurality of devices installed at building installation locations, a management apparatus, and a notification apparatus. The management apparatus estimates arrangement information of the devices based on information relating to electromagnetic waves acquired by the devices performing wireless communication with each other, and calculates one or more candidates for the device installed at the installation location by collating the arrangement information with the position information of the installation locations. In a case in which the management apparatus determines that the device actually installed at the installation location cannot be identified from the one or more candidates for the device installed at the installation location, the notification apparatus notifies the position information of the installation location and the unique information of the one or more candidates for the device installed at the installation location.
