Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If four 1.08 GHz bands are assigned according to the millimeter wave communications standard, then compatibility with international standards is achieved, but bandwidth utilization ratio and data transmission rate are reduced
Solution Approach 1:
The patent implements dynamic channel allocation where network devices can switch between 1.08 GHz and 2.16 GHz bandwidth channels based on real-time occupancy information. The system negotiates channel switching between adjacent networks, allowing flexible adaptation of channel width and position to maximize bandwidth utilization while maintaining compatibility with devices requiring 1.08 GHz operation.
Solution Approach 2:
The system changes operational parameters by allowing network devices to operate on different channel widths (1.08 GHz or 2.16 GHz) and at different frequency positions. Through negotiation protocols, devices dynamically adjust their operating parameters to utilize idle subchannels efficiently, transforming the fixed channel assignment into a flexible parameter-based allocation system.
2Adaptability or versatility
If four 1.08 GHz bands are assigned according to the millimeter wave communications standard, then compatibility with international standards is achieved, but data transmission rate is reduced
Solution Approach 1:
The system dynamically selects operating speed by negotiating channel allocation between adjacent networks. When wider 2.16 GHz channels are available through negotiation, devices operate at higher data transmission rates. The dynamic nature allows the system to achieve maximum speed when conditions permit while maintaining compatibility when necessary.
Solution Approach 2:
Data transmission rate is improved by changing the channel width parameter from fixed 1.08 GHz to variable width (1.08 GHz or 2.16 GHz). The negotiation protocol enables devices to select optimal parameter combinations that maximize transmission speed while ensuring compatibility requirements are met through coordinated channel selection.
3Productivity
If channel negotiation is performed between adjacent networks to allocate idle channels, then bandwidth utilization is improved, but channel switching complexity increases
Solution Approach 1:
The channel negotiation system operates autonomously between adjacent networks without requiring centralized control. Network devices automatically exchange occupancy information, negotiate available channels, and execute switching decisions independently. This self-service mechanism reduces the need for complex external coordination while achieving optimal bandwidth utilization.
Solution Approach 2:
The system implements feedback loops where network devices continuously monitor channel occupancy, exchange information with adjacent networks, and adjust their channel allocation based on received feedback. This iterative negotiation process automates the complexity of channel switching, allowing the system to adapt to changing conditions while managing complexity through decentralized feedback-based decision making.
