Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing communication infrastructure (internet, BLE, Wi-Fi Direct) is used for data communication, then data communication can be carried out under normal conditions, but communication cannot be maintained during natural disasters or wars when infrastructure is damaged
Solution Approach 1:
The patent segments the communication system into multiple independent wireless communication systems (BLE, Wi-Fi Direct, and other systems). Each system operates independently with its own distance range, allowing the device to switch between segmented communication channels when infrastructure is damaged, thereby maintaining communication reliability without depending on a single infrastructure.
Solution Approach 2:
The portable wireless communication apparatus is designed with multi-functionality by incorporating multiple wireless communication systems (first to N-th systems) that can operate independently. This universal design enables the device to adapt to various communication scenarios including disaster situations where traditional infrastructure is unavailable, resolving the contradiction between reliability and adaptability to infrastructure loss.
2Reliability
If multiple wireless communication systems are integrated into portable devices, then communication can be maintained across different distance ranges, but device complexity increases
Solution Approach 1:
The patent implements dynamic selection among multiple wireless communication systems based on detected distance. The device dynamically switches between BLE (short distance), Wi-Fi Direct (medium distance), and other systems (long distance) according to real-time distance detection results. This dynamic approach maintains comprehensive communication coverage while managing system complexity through automated distance-based selection rather than requiring all systems to operate simultaneously.
Solution Approach 2:
The patent changes the operational parameter (wireless communication system selection) based on the distance parameter detected by the distance-detecting apparatus. By adjusting which communication system is active according to distance parameters, the device achieves comprehensive communication coverage across different ranges while managing complexity through parameter-based selection rather than constant multi-system operation.
3Productivity
If automatic distance-based communication system selection is implemented, then optimal communication can be achieved, but processing time and computational resources increase
Solution Approach 1:
The patent implements preliminary action by pre-configuring multiple wireless communication systems (first to N-th systems) with different distance ranges in the device. The distance-detecting apparatus continuously monitors distance, and the system has pre-established selection criteria for switching between communication systems. This preliminary preparation enables rapid automatic selection without requiring complex real-time analysis, thus improving communication efficiency while minimizing system selection time.
