Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the device uses a standard processor to manage sensor data and control wireless communication, then the processing capability is sufficient, but the processor load and power consumption increase
Solution Approach 1:
The patent divides the processing tasks by introducing a sensor hub that specifically handles sensor data acquisition, processing, and control signal generation for wireless communication. This segmentation separates the sensor management functions from the main processor, reducing the main processor's load and power consumption while maintaining adequate processing capability for overall device operations.
2Reliability
If the device uses a fixed antenna configuration, then the device structure is simple, but the antenna performance deteriorates when the user's body affects the antenna
Solution Approach 1:
The patent implements dynamic antenna configuration by enabling the sensor hub to control the wireless communication module to switch between different antennas based on real-time sensor data. This dynamic adaptation allows the system to maintain reliable antenna performance despite user body effects, while the complexity is managed through automated control rather than manual configuration.
Solution Approach 2:
The system uses sensor data as feedback to monitor the antenna performance environment and automatically adjusts the antenna configuration through the sensor hub. This feedback mechanism enables the device to respond to changing conditions (such as user grip) and maintain optimal antenna performance without requiring complex manual intervention.
3Reliability
If the device does not adapt to surrounding environment changes, then the device operation is simple, but the wireless communication performance deteriorates due to user's body effects
Solution Approach 1:
The sensor hub acts as an intermediary between the sensors and the wireless communication module. It processes sensor data, determines environmental conditions (such as user grip effects), and generates appropriate control signals to adjust the wireless communication configuration. This intermediary approach maintains reliable communication performance while managing the complexity of adaptive control through a dedicated control component.
