Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional techniques are used to manage audio streams, then the system structure is simple, but the ability to recognize and manage multiple independent audio streams is insufficient

Engineering Contradiction:

Improveability to recognize and manage multiple independent audio streamsVSAvoidsystem structure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the audio management system into distinct functional modules: monitoring logic for detecting audio streams, testing logic for evaluating audio channel capabilities, selection logic for choosing appropriate audio streams, split logic for dividing audio streams into channels, and synchronization logic for coordinating audio output. This segmentation enables the system to handle multiple independent audio streams while maintaining manageable complexity through modular design.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If multiple standalone speakers are used to achieve independent audio streams, then audio stream independence is improved, but device quantity and power consumption increase

Engineering Contradiction:

Improveaudio stream independenceVSAvoidpower consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent merges multiple audio stream processing capabilities into a single display device by implementing audio splitting functionality that divides a single audio stream into multiple independent audio channels. This allows the display device to replace multiple standalone speakers while maintaining audio stream independence and reducing the number of separate devices required, thereby lowering power consumption.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The display device is designed with multi-functionality, serving both as a visual display and an audio output device with the capability to generate multiple independent audio channels from a single audio stream. This universal design eliminates the need for separate audio equipment, reducing both device quantity and overall power consumption while maintaining audio stream independence.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Productivity

If audio streams are split into multiple channels, then audio stream management capability is improved, but processing complexity increases

Engineering Contradiction:

Improveaudio stream management capabilityVSAvoidprocessing complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent implements preliminary action by having the testing logic evaluate audio channel capabilities and characteristics before the split logic divides the audio stream. This advance preparation allows the selection logic to choose appropriate audio streams based on pre-assessed channel capabilities, simplifying the actual splitting process and reducing processing complexity during runtime while maintaining high audio stream management capability.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The synchronization logic continuously monitors the audio channel output and provides feedback to the split logic, enabling dynamic adjustment of the audio stream splitting process. This feedback mechanism ensures proper synchronization and coordination of multiple audio channels while simplifying the overall processing by automatically handling timing and coordination issues that would otherwise require complex manual configuration.

Inventive Principle:

Principle #23Feedback

AI summary

A mechanism is described for facilitating display-based audio splitting in media environments, according to one embodiment. A method of embodiments, as described herein, includes receiving, at a computing device, a request to split audio streams associated with audio channels in communication with the computing device serving as a host device, wherein the audio streams are generated by one or more applications; selecting a split mode to facilitate splitting of the audio streams; and splitting the audio streams based on the split mode such that the audio streams are continuously mapped to the audio channels to adjust for delays and fine tuning.
