Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple Bluetooth connections share the same Bluetooth air interface, then device connectivity is improved, but air interface resource conflicts occur causing processing failures or excessive delays

Engineering Contradiction:

ImproveBluetooth connection capabilityVSAvoidCommunication request processing success rate

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent implements dynamic adjustment of Bluetooth operating parameters including connection interval, slave delay, and packet length based on real-time detection of air interface resource occupancy. When resource conflicts are detected, the system dynamically modifies these parameters to resolve conflicts and ensure successful communication request processing while maintaining multiple active connections.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If multiple Bluetooth connections share the same Bluetooth air interface, then device connectivity is improved, but processing duration becomes excessively long

Engineering Contradiction:

ImproveBluetooth connection capabilityVSAvoidCommunication request processing time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent performs preliminary detection of Bluetooth air interface resource occupancy status before processing communication requests. By detecting whether the air interface is currently occupied and predicting potential resource conflicts in advance, the system can proactively adjust operating parameters to prevent processing delays, ensuring timely handling of communication requests while supporting multiple connections.

AI summary

A BLUETOOTH communication method includes, when obtaining a BLUETOOTH communication request corresponding to a second terminal device, a first terminal device determine, based on the BLUETOOTH communication request and connection information of an existing BLUETOOTH connection in the first terminal device, a BLUETOOTH operating mode currently corresponding to the first terminal device, to adjust an operating parameter of BLUETOOTH based on the BLUETOOTH operating mode. Further, the first terminal device adjusts current occupation on a BLUETOOTH air interface by the existing BLUETOOTH connection in the first terminal device, to reduce a BLUETOOTH air interface resource conflict in a plurality of BLUETOOTH connections.
