Sensor Data Transfer via Automatic Device Linking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing monitoring devices often require manual intervention to transfer sensor data, leading to inefficiencies and fragmentation of user data across multiple devices, which can hinder seamless integration and comprehensive user data management.
Innovation Solution
A system that enables wireless communication between multiple monitoring devices and a server, allowing for the automatic transfer of sensor data through a network, using a first monitoring device to establish connections with other devices and the server, and facilitating the detection and synchronization of data from multiple sources.

Engineering Contradiction Analysis
1Productivity
If manual intervention is used to transfer sensor data between devices, then data transfer can be controlled by users, but data transfer efficiency is reduced and user data becomes fragmented across multiple devices
Solution Approach 1:
The monitoring device automatically performs data transfer operations without requiring user intervention. The device autonomously establishes wireless connections with other devices, retrieves their sensor data, and transfers it to the server, eliminating the need for manual user actions while maintaining controlled data sharing.
Solution Approach 2:
The monitoring device acts as an intermediary between multiple sensor devices and the server. It receives device information from the server, uses this information to automatically connect to other devices, retrieves their data, and forwards it to the server, thereby facilitating efficient data aggregation without direct user involvement.
2Quantity of substance
If multiple monitoring devices are used to collect sensor data from the same user, then comprehensive user data can be gathered, but data fragmentation occurs across devices
Solution Approach 1:
The system merges data from multiple monitoring devices by having the first device automatically retrieve data from second devices and transfer all data to a single server. This consolidates fragmented data from multiple sources into a unified dataset, maintaining comprehensive user information without fragmentation.
Solution Approach 2:
The monitoring device is designed with multi-functional capabilities: it collects its own sensor data, automatically discovers and connects to other user devices, retrieves their data, and transfers everything to the server. This universal functionality enables comprehensive data aggregation from multiple devices through a single coordinated system.
3Productivity
If automatic device detection and connection is implemented, then data transfer efficiency improves, but device complexity increases
Solution Approach 1:
The server performs preliminary actions by storing device information (device identifiers and access information) before data transfer is needed. When the first monitoring device needs to connect to other devices, it can directly use this pre-stored information to establish connections quickly, reducing the complexity of real-time device discovery while maintaining automatic data transfer efficiency.
