Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data messages are transmitted individually through the wireless interface, then data transmission simplicity is maintained, but data transmission efficiency deteriorates due to limited wireless data rates
Solution Approach 1:
The patent merges multiple individual data messages into a single aggregated data structure before transmission through the wireless interface. The data concentrator module combines uplink messages from multiple client applications into one aggregated message, and similarly combines downlink messages received from the server, thereby reducing the number of wireless transmissions required and improving overall data transmission efficiency.
Solution Approach 2:
The patent segments the data handling process into distinct functional modules: client applications generate individual messages, the data concentrator module aggregates and compresses these messages into structured formats, and the host server further processes and routes them. This segmentation allows each module to specialize in specific tasks, improving efficiency without overwhelming the system with complexity.
2Productivity
If multiple individual data messages are transmitted over the wireless link, then message granularity is maintained, but wireless link bandwidth is wasted due to repeated protocol overhead
Solution Approach 1:
The patent combines multiple data messages into a single aggregated structure that includes a common header containing protocol information. This approach transmits the protocol overhead only once per aggregated message set rather than repeating it for each individual message, thereby significantly improving wireless link utilization and reducing redundant data transmission.
3Productivity
If data is compressed and aggregated at the mobile device, then wireless transmission efficiency is improved, but device processing requirements increase
Solution Approach 1:
The patent performs data aggregation and compression as preliminary actions at the mobile device before transmission, preparing the data in an optimized format. This preliminary processing reduces the amount of data that needs to be transmitted and processed during actual communication, thereby improving transmission rates while managing device processing requirements through efficient pre-processing.
4Productivity
If a single TCP socket is used for communication tunnel, then connection simplicity is maintained, but data flow optimization is limited
Solution Approach 1:
The patent segments the data flow within the single TCP socket communication tunnel by implementing separate logical channels for uplink and downlink data. The data concentrator module creates distinct data structures with clear delimiters and routing information, allowing efficient data flow management and optimization within the simplified single-socket architecture without requiring multiple physical connections.
