Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems struggle to identify and acquire information from a specific communication sensor device among multiple devices in close proximity, especially when numerous devices are present, leading to difficulties in distinguishing and pairing with the designated device for effective communication.
Innovation Solution
An acquired-information output terminal that includes a first acquisition unit for identifying a specific device using near field communication and a second acquisition unit for establishing communication to acquire and display information from that device, potentially with the aid of a management server for managing and storing sensor data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple communication sensor devices are present in close proximity, then the system can monitor more areas, but it becomes difficult to identify and acquire information from a specific device
Solution Approach 1:
The patent divides the identification process into two distinct stages: first using near field communication to acquire the identifier of a specific sensor device through close proximity contact, then using wireless communication to acquire measurement information. This segmentation allows the system to handle multiple sensor devices effectively by first selecting one through NFC and then communicating with it wirelessly.
Solution Approach 2:
The patent introduces an identifier as an intermediary element that bridges near field communication and wireless communication. The identifier acquired through NFC serves as a key to establish subsequent wireless communication with the specific sensor device, enabling selective information acquisition from among multiple devices.
2Measurement precision
If near field communication is used to identify a specific device, then device identification becomes possible, but additional communication steps are required
Solution Approach 1:
The patent performs device identification through near field communication as a preliminary action before establishing wireless communication. By acquiring the identifier first through NFC, the system prepares the necessary information in advance, which then enables efficient wireless communication and information acquisition without repeated identification steps.
3Ease of operation
If wireless communication is used to acquire information from multiple devices, then information can be obtained remotely, but it becomes impossible to determine which specific device is transmitting
Solution Approach 1:
The patent uses the identifier acquired through near field communication as feedback to guide wireless communication. The system feeds the NFC-acquired identifier into the wireless communication process, allowing it to selectively acquire information from the specific sensor device corresponding to that identifier, thus maintaining device source identification while enabling remote information acquisition.

AI summary
An acquired-information output terminal that acquires only information output by a specific device includes: a first acquisition unit for acquiring an identifier corresponding to the specific device; and a second acquisition unit that is different from the first acquisition unit and uses the identifier acquired by the first acquisition unit for establishing external communication that allows the information output by the specific device to be acquired using the identifier acquired by the first acquisition unit and acquiring the information, the second acquisition unit being different from the first acquisition unit.
