Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional security systems are used, then security coverage is provided, but the systems are unreliable and easily detected
Solution Approach 1:
The patent extracts the security signaling function from traditional audible/visible security systems and transfers it to the inaudible ultrasonic frequency range. The security presence is communicated through ultrasonic tones that are imperceptible to humans, making the system undetectable while maintaining reliability through encoded data transmission in the ultrasonic carrier waves.
Solution Approach 2:
The patent changes the 'frequency color' of security signals from the audible range to the inaudible ultrasonic range. By shifting the operational frequency beyond human hearing capability, the system achieves undetectability while maintaining full functional capability through sophisticated modulation and encoding schemes.
2Reliability
If traditional security systems are used, then security monitoring is provided, but power consumption is high
Solution Approach 1:
The patent implements periodic transmission of ultrasonic tones rather than continuous operation. The transmitters send coded ultrasonic signals at intervals, allowing the system to maintain monitoring capability while significantly reducing power consumption compared to continuous operation. The periodic nature allows battery-powered devices to extend operational life.
Solution Approach 2:
The patent replaces power-intensive traditional security system components with ultrasonic transmission technology. By using acoustic waves in the ultrasonic range carrier data, the system achieves efficient power utilization compared to traditional radio frequency or audible alarm systems, enabling long-duration battery operation.
3Loss of information
If inaudible tones are broadcast with audio content, then data transmission is achieved, but signal detection complexity increases
Solution Approach 1:
The patent uses ultrasonic carrier waves as an intermediary medium to transmit data within the audio content. The ultrasonic tones serve as a carrier that embeds security and tracking data, allowing information transmission without direct human perception. Receivers detect and decode these ultrasonic carriers to extract the embedded data.
Solution Approach 2:
The patent employs sophisticated modulation techniques that change multiple parameters of the ultrasonic carrier wave including frequency, amplitude, and phase to encode data. This parameter modulation allows high-capacity data transmission within the inaudible tone while requiring corresponding detection complexity at the receiver end to decode the modulated signals.
Data Source
AI summary
