Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional Bluetooth audio technology is used for one-to-one connection between two devices, then the technology is simple and easy to implement, but it is not suitable for supporting audio data transmission/reception between multiple devices

Engineering Contradiction:
Improvemulti-device connection capabilityVSAvoidconnection management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies universality by enabling Bluetooth audio technology to serve multiple functions: it maintains support for traditional one-to-one connections while simultaneously supporting one-to-many and many-to-many connection topologies. The system can adaptively switch between different connection modes based on the number of devices and audio requirements, making the technology universally applicable to various audio transmission scenarios without requiring separate specialized systems for each connection type.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent implements dynamics by making the connection topology flexible and changeable. The system can dynamically transition between different connection modes (one-to-one, one-to-many, many-to-many) based on real-time requirements. Devices can be added or removed from the audio network dynamically, and the system adapts its connection management strategy accordingly, rather than being fixed in a single connection mode.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the number of Bluetooth audio devices is increased to support multi-device connections, then multi-device audio transmission is enabled, but power consumption for searching for peripheral devices increases

Engineering Contradiction:
Improvemulti-device audio supportVSAvoidpower consumption for device search
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent applies preliminary action by having devices perform audio capability discovery and state information exchange during the initial connection establishment phase. This preliminary gathering of information about audio capabilities, supported formats, and current device states allows the system to make informed decisions about connection topology and audio parameter configuration before actual audio transmission begins, avoiding the need for repeated discovery searches during operation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback mechanisms where devices continuously exchange information about their current audio playback state, supported audio formats, and connection status. This feedback allows the central device to optimize audio transmission parameters and connection management based on real-time device states, reducing the need for exhaustive device searches and enabling more efficient power management in multi-device scenarios.

Inventive Principle:
Principle #23Feedback

3Productivity

If the state of another peripheral device is not considered when changing the state of the device, then state transition is simple and fast, but unnecessary procedures are performed

Engineering Contradiction:
Improvestate transition efficiencyVSAvoidenergy wasted on unnecessary procedures
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The patent applies feedback by implementing a mechanism where devices exchange information about their current audio playback state, supported formats, and connection status before state transitions. This feedback allows the system to determine whether a state transition is actually necessary based on the current configuration of all devices in the audio network, avoiding redundant state changes and optimizing energy consumption while maintaining efficient audio transmission.

Inventive Principle:
Principle #23Feedback

AI summary

The present disclosure relates to a method, a device, and a computer program for controlling and managing a state of a peripheral device in a wireless communication system, and a recording medium therefor. According to an embodiment of the present disclosure, a method for changing an audio stream session-related state may include the steps of: acquiring information relating to a current audio stream session-related state of a second device before a first device in a first audio stream session-related state performs transition of an audio stream session-related state; determining a second audio stream session-related state of the first device at least on the basis of the current audio stream session-related state of the second device; and performing the transition of the audio stream session-related state by the first device on the basis of the second audio stream session-related state.
