Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If personal mobility devices are equipped with radar sensors to detect nearby objects, then object detection capability is improved, but device complexity and cost increase
Solution Approach 1:
The patent combines radar sensors with short-range communication networks (BLE) to merge detection capabilities. Multiple personal mobility devices share detection data through wireless communication, creating a collective awareness system where each device benefits from the sensor data of others without carrying all sensors itself.
Solution Approach 2:
The system makes radar detection capability universal across the fleet of personal mobility devices by enabling data sharing. A single device's radar detections become available to all other devices in the network, allowing any device to access object information regardless of its own sensor configuration.
2Measurement precision
If multiple sensors are installed on personal mobility devices to improve detection coverage, then measurement precision is improved, but use of energy increases
Solution Approach 1:
The patent merges the sensing functions of multiple devices into a shared detection network. Instead of each device running its own full sensor suite, devices combine their individual radar detections through wireless communication to achieve comprehensive coverage equivalent to multiple sensors.
Solution Approach 2:
Each personal mobility device performs self-detection using its own radar sensor and contributes this data to the network. The collective detection coverage is achieved through self-service detection by individual devices rather than requiring each device to have extensive sensor arrays.
3Measurement precision
If radar sensors and short-range communication networks are integrated, then object recognition accuracy is improved, but device complexity increases
Solution Approach 1:
The system creates a universal communication protocol that enables different devices to share detection data seamlessly. The BLE network serves multiple functions: data transmission, device identification, and collaborative detection, reducing the need for specialized complex integration for each function.
