Measurement Device Multi-App Data Transfer via Identifier Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing measurement devices struggle to efficiently transfer data to multiple applications installed on a single information terminal, often resulting in only the first connected application acquiring the data, while others are unable to do so.
Innovation Solution
The measurement device is equipped with a wireless communication unit, a storage unit for identifiers, and a control unit that executes separate controls for each application, allowing it to communicate with multiple applications using shared identifiers without the need for multiple wireless communication units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a measurement device uses a single wireless communication unit to communicate with multiple applications, then device complexity is reduced, but data transfer reliability deteriorates because only the first connected application can acquire data
Solution Approach 1:
The patent segments the identifier resource into multiple distinct identifiers (first identifier and second identifier) stored in the storage unit. The control unit selectively uses different identifiers for different applications, allowing simultaneous or sequential connections without conflict. This segmentation of the identification resource resolves the contradiction by enabling multiple reliable connections while maintaining a single wireless communication unit.
Solution Approach 2:
The patent performs preliminary action by pre-storing multiple identifiers (first identifier and second identifier) in the storage unit before actual communication occurs. The control unit is pre-configured to select appropriate identifiers based on which application is connecting. This advance preparation ensures that when multiple applications need to connect, the device can reliably manage each connection with the appropriate identifier, avoiding conflicts without needing multiple physical communication units.
2Productivity
If multiple applications simultaneously start connection operations when the measurement device starts advertisement, then data acquisition speed is improved, but connection reliability deteriorates because only the first application succeeds
Solution Approach 1:
The patent introduces identifiers as an intermediary layer between the wireless communication unit and multiple applications. The control unit acts as a mediator that receives connection requests from multiple applications simultaneously, selects the appropriate identifier from storage, and manages the connection process. This intermediary mechanism allows simultaneous connection attempts without conflict, as each application can be assigned a unique identifier, ensuring both high productivity and connection reliability.
3Adaptability or versatility
If the measurement device stores multiple identifiers for different applications, then adaptability to multiple applications is improved, but storage unit complexity increases
Solution Approach 1:
The patent implements universality by designing a single storage unit that can store multiple identifiers (first identifier, second identifier, and potentially more). This storage unit serves multiple functions: storing identifiers for different applications, managing connection state information, and supporting various communication protocols. The control unit universally manages all identifiers and selects the appropriate one based on the connecting application. This multi-functional design achieves high adaptability while avoiding the need for separate storage structures for each application.
Data Source
AI summary
To provide a measurement device and a control program that can perform data transfer with a plurality of applications in one information terminal. A data storage unit of a measurement device stores a first identifier for identifying the measurement device in wireless communication by a wireless communication unit and a second identifier for identifying the measurement device in the wireless communication by the wireless communication unit. A controller of the measurement device performs a first control that causes the wireless communication unit to perform the wireless communication with a first application using the first identifier. The controller also performs a second control that causes the wireless communication unit to execute the wireless communication with a second application using the second identifier.
