Wireless TV Transmitter Receiver Power Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless TV systems require separate on/off operations for the transmitter and receiver, leading to inconvenient power wastage and inefficiency, as the transmitter cannot be turned off using the remote control.
Innovation Solution
A method and apparatus that allow both the transmitter and receiver of a wireless TV to be turned on/off with a single remote control operation, where the receiver sends an on/off command to the transmitter, which then checks the power and radio signal conditions before controlling both units accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the receiver is turned on/off independently using the remote control, then the receiver operation is convenient, but the transmitter cannot be turned off remotely leading to power waste
Solution Approach 1:
The patent combines the on/off control functions of the transmitter and receiver into a single remote control operation. When the user presses the on/off button, the system merges both control actions so that both transmitter and receiver are turned off simultaneously, eliminating the need for separate operations and preventing energy waste.
Solution Approach 2:
The system uses feedback mechanisms where the receiver sends a signal to the transmitter when turned off, which then automatically turns off the transmitter as well. This feedback loop ensures that both components are controlled consistently and prevents the transmitter from remaining on unnecessarily.
2Adaptability or versatility
If the transmitter and receiver are controlled separately, then each component can be optimized independently, but the overall system control becomes complex and inconvenient
Solution Approach 1:
The remote control is designed with multi-functionality to handle both transmitter and receiver control. The same on/off button performs dual functions: controlling the receiver directly and triggering the transmitter to turn off as well, simplifying the overall control system while maintaining adaptability.
Solution Approach 2:
The control system is segmented into distinct control paths: one path for receiver control and another for transmitter control. However, these paths are coordinated through communication signals, allowing independent optimization of control logic while achieving unified operation through the remote control.
3Reliability
If the transmitter remains on while the receiver is off, then the transmitter can maintain signal readiness, but power consumption increases unnecessarily
Solution Approach 1:
The system performs preliminary action by having the receiver check its off-state condition and send a signal to the transmitter before the transmitter actually turns off. This ensures that the transmitter is turned off only after confirming the receiver is properly off, maintaining reliability while preventing unnecessary energy consumption.
Solution Approach 2:
The transmitter receives feedback from the receiver about its power state and uses this information to control its own power state accordingly. This feedback mechanism ensures the transmitter turns off automatically when the receiver is off, balancing reliability with energy efficiency.
