Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data is transmitted using traditional single-link Wi-Fi technology, then the system is simple to implement, but the data transmission rate and throughput are limited
Solution Approach 1:
The patent segments the data transmission process by dividing data packets into multiple packets and transmitting them through different frequency bands (2.4GHz, 5GHz, 6GHz) simultaneously. Each frequency band operates as an independent transmission channel, allowing parallel data flow that increases overall throughput while maintaining manageable complexity through modular channel management
Solution Approach 2:
The patent transitions from single-frequency-band transmission to multi-frequency-band transmission by adding the frequency dimension. Data packets are distributed across multiple frequency dimensions (2.4GHz, 5GHz, 6GHz bands), effectively transforming a one-dimensional transmission problem into a multi-dimensional solution that increases capacity without proportionally increasing complexity
2Productivity
If multiple frequency bands are used for data transmission, then throughput increases, but the management and coordination of frequency bands becomes more complex
Solution Approach 1:
The patent merges multiple frequency bands (2.4GHz, 5GHz, 6GHz) into a unified multi-link transmission system. By combining these bands and assigning them a common sequence number, the system manages multiple channels through a single coordinated framework, reducing the overhead of managing each band separately while maintaining high throughput across all bands
Solution Approach 2:
The patent creates a universal sequence number assignment mechanism that works across all frequency bands. The same sequence number is used to identify corresponding data packets regardless of which frequency band they traverse, providing a universal identification system that simplifies coordination and management across diverse frequency channels
3Reliability
If data packets are transmitted on different frequency bands, then network reliability improves, but the sequence number assignment becomes more complex
Solution Approach 1:
The patent applies homogeneity by assigning the same sequence number to data packets transmitted across different frequency bands. This uniform identification approach ensures that packets from multiple bands can be reliably matched and reassembled without requiring complex band-specific sequencing, thereby improving reliability while maintaining simplicity in packet identification
4Ease of operation
If the same sequence number is assigned to data packets on different frequency bands, then packet identification becomes simpler, but the risk of packet confusion increases
Solution Approach 1:
The patent implements feedback mechanisms where receiving devices send acknowledgments (ACKs) for received packets back to transmitting devices. This feedback loop allows the system to verify successful packet delivery and request retransmission if needed, ensuring that simple sequence number assignment does not compromise reliability since the feedback mechanism can detect and correct any packet confusion
