Problem

Users of electronic devices, such as multimedia decoders and smartphones, face issues with unpredictable electricity consumption, leading to inadequate power supply, which can result in failed or interrupted content rendering due to insufficient battery charge or incorrect power connections.

Innovation Solution

A method that analyzes the requested multimedia content's rendering quality and matches it with the device's power supply state, adjusting the quality to ensure seamless processing and rendering by modifying the complexity of the content based on available power, using adaptive streaming techniques and power supply characteristics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If the device processes multimedia content at high quality, then the rendering quality and user experience are improved, but the electricity consumption increases and may exceed the power supply capacity

Engineering Contradiction:

Improverendering qualityVSAvoidelectricity consumption

Core Design Contradiction:

Manufacturing precisionVSUse of energy by moving object

Solution Approach 1:

The patent implements dynamic quality adaptation by continuously monitoring the power supply state and adjusting the content rendering quality in real-time. The system transitions from static quality selection to dynamic quality adjustment, allowing the device to optimize between rendering quality and power consumption based on current battery charge level or power connection status.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the quality parameter of multimedia content based on power supply conditions. By modifying parameters such as resolution, frame rate, and codec complexity according to the available power, the system resolves the contradiction between high quality rendering and limited power consumption.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If the device automatically adjusts content quality based on power supply state, then the reliability of content rendering is improved, but the device complexity increases

Engineering Contradiction:

Improvecontent rendering reliabilityVSAvoidpower management complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements self-service by having the device automatically monitor its own power supply state and make quality adjustment decisions without user intervention. The system self-regulates by detecting battery charge level or power connection status and autonomously selecting appropriate content quality, reducing the need for complex user interfaces or manual configuration.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent employs feedback mechanisms where the device continuously monitors power supply state and uses this information to adjust content quality. This closed-loop feedback system ensures reliable rendering by adapting to changing power conditions, while the automation of the feedback process minimizes added complexity compared to manual control approaches.

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If the device provides multiple quality levels for content, then the adaptability to different power supplies is improved, but the processing complexity and time to select appropriate quality increases

Engineering Contradiction:

Improvepower supply adaptabilityVSAvoidquality selection time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-defining multiple quality levels and their corresponding power consumption characteristics before content processing begins. The system prepares quality profiles in advance, allowing rapid selection based on current power supply state without requiring complex real-time analysis or calculation during content delivery.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent uses partial action by implementing quality adjustment mechanisms that focus on the most critical quality parameters (such as resolution and frame rate) rather than optimizing all possible content attributes. This selective approach provides sufficient adaptability to different power supplies while minimizing the processing time and complexity required for quality selection.

Inventive Principle:

Principle #16Partial or excessive action
