Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems lack efficient handover mechanisms between different communication formats, such as Bluetooth and NFC, which limits seamless data transfer and device interoperability in multi-format environments.
Innovation Solution
A mobile wireless communication device with a control module that establishes an initial link using one format (e.g., NFC) and determines the device type to establish subsequent links using another format (e.g., Bluetooth) for enhanced communication handovers, enabling efficient communication across various device types and formats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mobile device uses multiple wireless communication formats (Bluetooth, NFC, WLAN), then the device's adaptability and interoperability improve, but the complexity of managing handovers between formats increases
Solution Approach 1:
The patent introduces an NFC-based intermediary mechanism that acts as a bridge between Bluetooth and WLAN communication formats. The NFC format serves as a simple initial connection medium that triggers the handover to more capable formats (Bluetooth or WLAN), thereby managing the complexity of multi-format interoperability through a staged approach rather than direct management of all format combinations.
2Productivity
If the system establishes direct links between devices using complex formats like Bluetooth or WLAN, then communication efficiency improves, but the initial connection establishment becomes more difficult
Solution Approach 1:
The patent applies preliminary action by establishing an initial NFC connection before transitioning to more efficient communication formats. The NFC link is formed first as a simple, easy-to-establish connection that provides device identification and triggers the subsequent establishment of Bluetooth or WLAN links, which are more efficient for actual data transfer but more complex to initiate.
3Ease of operation
If the mobile device uses NFC for initial connection, then the ease of operation improves, but the communication speed and data transfer capability are limited
Solution Approach 1:
The patent implements a dynamic communication architecture where the system transitions from NFC (easy to connect, slow) to Bluetooth or WLAN (harder to connect, fast) based on the communication needs. The handover mechanism dynamically switches between communication formats, using NFC only for initial connection and device identification, then transitioning to higher-speed formats for actual data transfer, thus optimizing both ease of operation and speed at different stages.
