Intelligent Cable Mechanism for Power Recycling and Receiver Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing mobility and media capabilities of electronic devices, such as mobile phones and tablets, are hindered by their small size and limited battery life, which makes them inadequate for continuous media content viewing and requires frequent charging, often without the ability to maintain a media receiver as a power source during data transmission.
Innovation Solution
A cable system with a converter board that enables media data transmission and charging, using power from a media receiver, an external source, or both, to prevent automatic shutdown of the receiver and support various charging modes, including power recycling, full charging, normal charging, and fast charging, while also generating screen saver data to maintain the receiver as a power source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the electronic device is made small and mobile, then portability is improved, but battery life becomes insufficient for continuous media viewing
Solution Approach 1:
The patent introduces a media receiver as an intermediary device that provides power to the media transmitter during media playback. The receiver acts as a power mediator, supplying electrical power through the cable connection to extend the transmitter's operational duration without increasing its battery capacity.
Solution Approach 2:
The cable connection is designed to serve multiple functions simultaneously: data transmission and power transfer. The universal USB cable type can carry both media data signals and electrical power, allowing a single connection to fulfill both media playback and charging functions.
2Use of energy by moving object
If power is supplied during media data transmission, then charging capability is improved, but the receiver may shut down due to lack of media data
Solution Approach 1:
The system uses its own media data transmission function to maintain the receiver's operational state. By continuously transmitting media data through the cable, the system prevents the receiver from entering standby or shutdown modes, thereby maintaining its ability to supply power.
Solution Approach 2:
The cable connection simultaneously handles both media data transmission and power transfer functions. This multi-functionality allows the system to maintain the receiver's active state through data transmission while receiving power, resolving the conflict between charging and receiver stability.
3Reliability
If dedicated ports are used for each standard, then connection reliability is improved, but device complexity increases
Solution Approach 1:
The patent employs universal USB connectors on both the media transmitter and cable, allowing a single connector type to handle multiple functions including media data transmission and power transfer. This eliminates the need for dedicated ports for each standard while maintaining reliable connections through the standardized USB interface.
Data Source
AI summary
Provided are cables for transmitting media data from media transmitters to receivers and methods of using such cables for charging the transmitters. In certain embodiments, power for such charging may be obtained by the cable from the media receiver during media data transmission and may be recycled back to the transmitter. In other embodiments, charging may be performed while no media data is transmitted. Power may be supplied by a media receiver still connected to the cable, by an external power source, or both devices simultaneously. A cable may be configured to prevent an automatic shutdown of the media receiver due to lack of media data transmission and to, thereby, maintain the receiver as a power source. Specifically, a cable may generate screen saver data and transmit this data to the receiver. The cable may include a converter board for providing various functions.
