Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a client device uses another device as a wireless hotspot to access the Internet, then Internet access is enabled, but the client device consumes excessive bandwidth from the host device resulting in bandwidth loss and performance issues
Solution Approach 1:
The patent dynamically adjusts the communication protocol based on network conditions. The system monitors whether the host device is connected via cellular or WiFi network and switches between different protocols (e.g., TCP vs. UDP, or different TCP parameter settings) to optimize bandwidth consumption. This dynamic adaptation resolves the contradiction by making bandwidth usage flexible rather than fixed, allowing reliable connection while minimizing bandwidth loss.
Solution Approach 2:
The patent changes communication parameters such as TCP window size, buffer sizes, retransmission thresholds, and protocol selection based on the detected network type. When the host device is on cellular network, the system adjusts parameters to reduce bandwidth consumption. This parameter optimization enables maintaining connection reliability while significantly reducing the bandwidth loss that occurs with default settings.
2Productivity
If a client device uses another device as a wireless hotspot, then Internet access is provided, but throughput is reduced due to bandwidth consumption
Solution Approach 1:
The system dynamically selects and adjusts communication protocols based on real-time detection of the host device's network connection type. When cellular network is detected, the system switches to more bandwidth-efficient protocols or adjusts existing protocol parameters to reduce overhead and improve throughput. This dynamic behavior allows the system to maximize productivity while minimizing bandwidth consumption.
Solution Approach 2:
The patent implements parameter optimization by modifying communication settings such as packet size, transmission frequency, error correction levels, and protocol selection based on the detected network conditions. These parameter changes are specifically tuned to improve throughput while reducing bandwidth consumption, resolving the contradiction between productivity and energy loss.
3Speed
If a client device connects to a host device providing wireless hotspot, then wireless Internet access is enabled, but latency issues occur due to bandwidth constraints
Solution Approach 1:
The system dynamically adjusts communication protocols to prioritize low-latency applications when operating over cellular networks. By detecting the network type and switching to protocols with lower overhead and faster response times, the system improves response speed while being mindful of bandwidth constraints. This dynamic protocol selection resolves the contradiction between speed and bandwidth consumption.
Solution Approach 2:
The patent modifies communication parameters such as timeout values, retransmission limits, buffer sizes, and protocol selection to optimize for low latency when the host device is on cellular network. These parameter adjustments reduce the time delay in data transmission and reception while controlling bandwidth usage, thereby resolving the contradiction between response speed and bandwidth consumption.
