RF-Guided TV Stand Rotation for 3D Viewer Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing TV stand systems are not user-friendly, requiring users to manually or manually assistedly define their position relative to the TV and issue multiple commands to align the viewing angle, which is inefficient and often does not accurately adjust to the user's position in three-dimensional space.
Innovation Solution
A system comprising a remote control, RF signal sensors, and a turning mechanism that detects the user's position in three-dimensional space using a comparison of RF signal power levels from multiple sensors, allowing the TV stand to adjust its orientation with a single command by referencing a pre-created table to determine the necessary motor movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual or motorized rotation systems are used, then the TV stand can be turned to different positions, but the operation becomes complex and time-consuming requiring multiple commands
Solution Approach 1:
The system performs preliminary detection of the user's position using RF signal sensors before any rotation action is taken. By detecting the user's position in advance and using a pre-created reference table to determine the optimal viewing angle, the system eliminates the need for multiple manual commands and reduces calibration time to a single button press.
2Measurement precision
If multiple control buttons are required to define user position and turning direction, then precise control is achieved, but the device complexity increases
Solution Approach 1:
The system uses RF signal sensors to automatically detect the user's position without requiring manual input for position definition. The microprocessor automatically processes the signal power levels, compares them against a pre-created reference table, and determines the optimal turning direction and angle, eliminating the need for multiple control buttons while maintaining precision.
Solution Approach 2:
The patent replaces manual mechanical control (multiple buttons for position and direction) with an automated electronic system using RF signal detection and microprocessor control. This substitution reduces device complexity by eliminating physical control elements while maintaining or improving measurement precision through electronic sensing.
3Device complexity
If the TV stand turns to predefined directions only, then the control system is simplified, but the alignment precision with user viewing angle is reduced
Solution Approach 1:
The system uses a reference table that contains multiple parameters including signal power levels from different sensors and corresponding optimal turning angles. By changing the control approach from fixed predefined directions to dynamic angle selection based on detected signal parameters, the system achieves precise alignment while keeping the motor control mechanism relatively simple.
4Ease of operation
If a single command is used to initiate rotation, then the ease of operation is improved, but the ability to accurately detect user position in three-dimensional space must be enhanced
Solution Approach 1:
The system segments the three-dimensional space detection into multiple independent RF signal sensors positioned at different locations. Each sensor detects signal power independently, and the microprocessor combines these segmented measurements to calculate the user's position in three-dimensional space, enabling accurate detection with a single command initiation.
Solution Approach 2:
The patent introduces RF signal sensors as intermediaries between the user's position and the TV stand's rotation control. These sensors detect the user's position indirectly through RF signal power levels, translating spatial information into electrical signals that the microprocessor can process to determine the optimal viewing angle.
