Pan Subframe Broadcast for Peripheral Data Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for transferring large data packages, such as firmware updates, in peripheral device networks like ESL systems are inefficient due to the need for direct connections and subframe-specific broadcasting, which limits scalability and speed.
Innovation Solution
Implementing a pan subframe broadcast mechanism that allows network devices to divide large data packages into segments and transmit them via broadcast, enabling wireless communication devices to switch from subframe-specific to pan subframe broadcast mode to receive all subframes, thereby enhancing data transfer speed and scalability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If direct connections are used for data transfer in peripheral device networks, then data transfer reliability is maintained, but data transfer speed and scalability deteriorate
Solution Approach 1:
The patent segments large data packages into smaller sub-packages that can be transmitted through broadcast channels. This segmentation allows the system to maintain reliability through error checking and retransmission of individual sub-packages while achieving faster overall data transfer through parallel broadcast transmission to multiple devices simultaneously.
2Stability of the object's composition
If direct connections are used for data transfer, then connection stability is maintained, but network scalability deteriorates
Solution Approach 1:
The patent implements a universal broadcast mechanism that can serve multiple wireless communication devices simultaneously through a single transmission channel. This multi-functional approach allows the network to scale to accommodate numerous devices without requiring individual direct connections, thereby improving scalability while maintaining connection stability through established broadcast protocols.
3Use of energy by moving object
If subframe-specific broadcast mode is used, then power consumption is reduced, but data transfer efficiency deteriorates
Solution Approach 1:
The patent dynamically switches the wireless communication device between subframe-specific broadcast mode (for normal operation with lower power consumption) and pan subframe broadcast mode (for high-speed data transfer). This dynamic adaptation allows the system to optimize power consumption during regular operations while achieving high data transfer efficiency when large data packages need to be transmitted, resolving the contradiction between power efficiency and transfer efficiency.
