Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing communication infrastructure (internet, carrier networks) is used for data communication, then communication can be established quickly under normal conditions, but communication fails completely when infrastructure is damaged by natural disasters or conflicts
Solution Approach 1:
The communication system is segmented into multiple independent wireless communication systems (first to N-th systems) with different maximum communicable distances. Each system can operate independently, and the device can switch between them based on distance and availability, ensuring communication continues even if one system fails due to infrastructure damage.
Solution Approach 2:
The portable wireless communication apparatus is equipped with multiple wireless communication systems (BLE, Wi-Fi Direct, WDS, UWB) that can serve different communication needs and distance ranges. This multi-functionality allows the device to adapt to various communication scenarios without relying on a single infrastructure type.
2Adaptability or versatility
If a single wireless communication system is used in portable devices, then device complexity is reduced, but the device cannot adapt to varying communication distances and conditions
Solution Approach 1:
The device dynamically selects which wireless communication system to use based on the detected distance to the communication target. The distance-detecting apparatus continuously monitors distance, and the controller switches between communication systems (BLE for short distance, Wi-Fi Direct for medium distance, WDS for long distance) to optimize communication performance for each scenario.
Solution Approach 2:
The system changes operational parameters by selecting different communication systems based on distance parameters. When distance exceeds the maximum communicable distance of the current system, the device switches to another system with greater range, effectively adapting to varying distance conditions through parameter changes.
3Adaptability or versatility
If multiple wireless communication systems are integrated in portable devices, then the device can communicate over various distances and conditions, but device complexity increases
Solution Approach 1:
The device performs automatic distance detection and autonomous selection of the appropriate communication system without user intervention. The distance-detecting apparatus and controller work together to automatically determine which system to use, reducing the burden on users while managing the complexity of multiple integrated systems.
Solution Approach 2:
The system uses feedback from the distance-detecting apparatus to continuously monitor communication conditions and adjust the selected wireless communication system accordingly. This feedback mechanism ensures optimal communication performance while managing system complexity through automated control.
