Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If wireless communication is used to transmit high-definition image data, then transmission speed is improved, but transmission efficiency deteriorates due to time wastage and repeated photography
Solution Approach 1:
The patent changes the communication parameter from conventional frequency bands to millimeter wave frequency band (24GHz, 38GHz, 60GHz), which provides wider bandwidth and higher transmission rates, enabling real-time transmission of high-definition image data without repeated photography
Solution Approach 2:
The patent employs adjustable directional antennas at both the aerial device and base station that can dynamically adjust their radiation directions to track and maintain optimal communication links, ensuring stable high-speed transmission during movement
2Productivity
If conventional frequency bands are used for data transmission, then device complexity is reduced, but transmission efficiency deteriorates
Solution Approach 1:
The patent divides the communication system into two independent parts: the aerial device with its antenna module and the base station with its adjustable directional antenna. This segmentation allows each part to be optimized independently for millimeter wave communication without requiring complete system redesign
Solution Approach 2:
The adjustable directional antenna design can be applied to both the aerial device and base station, providing a universal solution that handles both data transmission and tracking functions, reducing overall system complexity despite using advanced millimeter wave technology
3Quantity of substance
If large storage devices are used in aerial devices, then data storage capacity is improved, but equipment costs increase
Solution Approach 1:
The patent extracts the storage function from the aerial device by enabling real-time wireless transmission of image data to the base station. This eliminates the need for large onboard storage devices in the aerial device, reducing its weight, size, and cost while maintaining full data availability at the base station
