Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If scan parameter uses factory default settings, then connection speed is improved, but data transmission stability deteriorates
Solution Approach 1:
The patent applies dynamics by making the scan parameters adjustable rather than fixed. The system dynamically changes scan window durations and scan types based on different usage scenarios. When connected to multiple Bluetooth devices, the terminal device adjusts scan parameters to allocate scan resources appropriately, ensuring both fast connection and stable data transmission.
Solution Approach 2:
The patent directly applies parameter changes by modifying scan window duration and scan type parameters. The terminal device adjusts these parameters based on the number of connected Bluetooth devices and current usage scenarios, transforming fixed factory defaults into adaptable parameters that optimize both connection speed and transmission stability.
2Speed
If scan window duration is increased for faster discovery, then connection speed is improved, but data transmission time is reduced causing lag
Solution Approach 1:
The patent makes scan window duration dynamic rather than static. The terminal device adjusts scan window duration based on the number of connected Bluetooth devices and current usage scenarios, allowing the system to optimize the balance between discovery speed and data transmission time in real-time.
Solution Approach 2:
The patent implements periodic adjustment of scan parameters. The terminal device periodically evaluates the current usage scenario and connected device count, then adjusts scan window duration accordingly, creating a rhythmic optimization cycle that maintains both fast discovery and adequate transmission time.
3Adaptability or versatility
If terminal device performs scanning during data transmission, then connection versatility is improved, but data transmission stability deteriorates
Solution Approach 1:
The patent applies dynamics by making scan parameters adjustable based on the number of connected devices. When multiple Bluetooth devices are connected, the terminal device dynamically adjusts scan parameters to reduce scan intensity, thereby maintaining connection versatility while improving data transmission stability.
4Device complexity
If factory default scan parameters are used, then device complexity is reduced, but adaptability to different usage scenarios deteriorates
Solution Approach 1:
The patent applies self-service by enabling the terminal device to automatically adjust its own scan parameters based on the current usage scenario and number of connected Bluetooth devices. The system autonomously optimizes scan window duration and scan type without requiring manual user configuration, thereby maintaining low complexity while achieving high adaptability.
