Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If no visual indicator is provided, then the device complexity is reduced, but the alignment precision and sound transmission efficiency deteriorate
Solution Approach 1:
The patent applies visual indicators (such as colored LEDs or visual markers) on the ultrasonic emitter to indicate the direction and status of audio transmission. These visual elements change state (e.g., color, illumination) to provide feedback on alignment, enabling users to precisely position receivers without adding complex mechanical or electronic alignment systems.
2Ease of operation
If visual feedback is added to indicate target position, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent implements visual feedback mechanisms that provide real-time information to users about the position and orientation of the intended target relative to the ultrasonic emitter. This feedback loop allows users to intuitively adjust the receiver position to achieve optimal alignment, significantly improving ease of operation. The visual indicators are integrated into the existing emitter structure, minimizing the increase in device complexity while maximizing operational simplicity.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The visual indicator ensures precise alignment of the intended receiver with the ultrasonic emitter, enhancing the efficiency of sound transmission while minimizing interference with unintended receivers, thereby improving the overall performance of the ultrasonic audio system.
Implementation Method 1
the flexible layer is configured to launch a pressure-wave representation of the audio modulated ultrasonic carrier signal into the air
Implementation Method 2
the second pole is configured to resonate in response to an audio-modulated signal and to launch a pressure-wave representation of the audio modulated ultrasonic carrier signal into the air
Implementation Method 3
when two sound waves with different frequencies are radiated simultaneously in the same medium, a modulated waveform including the sum and difference of the two frequencies is produced by the non-linear (parametric) interaction of the two sound waves

AI summary
A visual indicator is incorporated into an ultrasonic emitter/sound system for ultrasonic carrier audio applications. The visual indicator can be utilized to ensure that an orientation of the ultrasonic emitter is appropriate relative to a position of an intended target of the audio modulated ultrasonic carrier signal, or that a listener is appropriately located relative to the ultrasonic emitter such that it can receive a targeted audio transmission.
