Solution Overview

Problem

Players interacting with multiple audio and video devices during online gaming or streaming sessions face the challenge of needing to manually switch between different hardware inputs, which is cumbersome and inefficient.

Innovation Solution

An audio/video base station with integrated processors and communication interfaces automatically switches audio and video signals based on the docking or undocking of an audio transceiver, allowing seamless transitions between input devices without manual intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If players manually switch between different audio and video hardware inputs, then they can control multiple devices, but the operation becomes cumbersome and inefficient

Engineering Contradiction:
Improveease of switching audio/video inputsVSAvoidtime required to switch devices
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The base station automatically detects when an audio transceiver is docked or undocked and autonomously switches audio output routing without requiring player intervention. The system monitors transceiver presence and automatically terminates or establishes audio channels accordingly, making the switching process self-service and eliminating manual operation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The base station continuously monitors the docking status of the audio transceiver and uses this feedback to automatically adjust audio routing. When the transceiver is detected as undocked, the system receives feedback about the changed state and automatically switches audio output to alternative devices, creating a closed-loop control system that responds to real-time conditions.

Inventive Principle:
Principle #23Feedback

2Productivity

If the base station automatically switches audio output when transceiver is undocked, then switching efficiency improves, but system complexity increases

Engineering Contradiction:
Improveswitching speedVSAvoidcomplexity of audio routing control
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The base station serves multiple functions: it acts as an audio/video switcher, a communication hub, and an automatic device detector. By consolidating these functions into a single multi-functional device, the patent reduces the need for separate control systems and minimizes overall system complexity while enabling automatic switching capabilities.

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

Solution Approach 2:

The base station acts as an intermediary device between the audio transceiver and other audio output devices. It mediates the audio signal routing by receiving audio signals and automatically directing them to appropriate outputs based on transceiver presence, simplifying the control architecture by centralizing the switching logic in a single mediating component.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If the base station monitors transceiver docking status continuously, then automatic switching accuracy improves, but energy consumption increases

Engineering Contradiction:
Improveaccuracy of detecting transceiver statusVSAvoidenergy used by base station
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The base station performs docking status detection at periodic intervals rather than continuously, checking for the presence of the audio transceiver at defined moments. This periodic monitoring approach maintains reliable detection capability while reducing energy consumption compared to continuous monitoring, as the system only activates detection circuits when needed.

Inventive Principle:
Principle #19Periodic action

AI summary

Audio/video base stations may include a plurality of audio/video input ports. The base stations may include an audio/video output port. The base stations may include a communication interface that is coupleable with an audio transceiver. The base stations may include one or more processors. The base stations may include a memory device having instructions stored thereon that, when executed by the one or more processors, cause the audio/video base station to detect that the audio transceiver has been undocked from the audio/video base station. The instructions may further cause the base station to, in response to detecting that the audio transceiver has been undocked from the audio/video base station, automatically switching an audio output signal from the audio/video output port to the communication interface while continuing to transmit a video output signal to the audio/video output port.
