Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Media streaming devices face issues with instantaneous high power consumption requirements, leading to instability or errors when coupled with TVs, as they often rely on the TV's power supply without ensuring stable voltage conditions.
Innovation Solution
A media streaming device comprising a power manager, stream processor, and voltage detector that dynamically adjusts operation modes based on the stability of the supply voltage, switching to a lower power consumption mode when voltage is unstable to prevent errors and ensure stable operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the media streaming device operates with high power consumption requirements, then the media stream quality is improved, but the device becomes unstable or produces errors when coupled with TV power supply
Solution Approach 1:
The stream processor dynamically switches between first and second operating modes based on real-time voltage stability detection. When voltage is stable, it operates in the first mode for high-quality media streaming. When voltage becomes unstable, it automatically transitions to the second mode with lower power consumption to prevent errors, thus resolving the contradiction between maintaining high stream quality and ensuring device stability.
Solution Approach 2:
The system changes the operational parameters of the stream processor by switching between two distinct modes with different power consumption levels. This parameter change allows the device to adapt to varying power supply conditions, maintaining reliability while preserving the ability to deliver high-quality media streams when power conditions permit.
2Power
If the media streaming device uses a high-current power supply, then the instantaneous power consumption requirements are met, but the device complexity increases
Solution Approach 1:
The voltage detector continuously monitors the power supply voltage and automatically triggers mode switching without external intervention. The system serves itself by detecting voltage conditions and autonomously adjusting its own operation, eliminating the need for complex external power management circuits or user intervention while maintaining appropriate power consumption levels.
Solution Approach 2:
Instead of always operating at full power capacity, the system uses partial power (second mode with lower consumption) when voltage is unstable, and full power (first mode with higher consumption) only when voltage is stable. This partial action approach reduces the peak power supply requirements and simplifies the power supply system while maintaining the ability to handle high-power moments when needed.

AI summary
A media streaming device includes a power manager, a stream processor, and a voltage detector. The power manager receives a power signal from the media playback device to supply power to the stream processor. The stream processor provides media stream to the media playback device for playback. The voltage detector is electrically coupled to the stream processor and captures at least a part of the power supply current to the stream processor. The stream processor is configured to determine whether the power supply voltage remains stable. When the supply voltage remains stable, the stream processor operates in a first mode to provide media stream. When the power supply voltage is unstable, the stream processor operates in a second mode to provide media stream, and the power consumption of the stream processor in the second mode is lower than the power consumption in the first mode.
