Bone Conduction Signal Disruption via Frequency Shift
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bone conduction advertising technologies do not provide users with adequate control over receiving advertisements, particularly in situations where they may not want to be disturbed, such as when trying to sleep.
Innovation Solution
A device that can receive external signals and generate disruption signals to cancel or render inaudible bone conduction advertisements by shifting frequencies or using signal characteristics to cancel portions of the signal, allowing users to opt out of unwanted advertisements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If bone conduction advertising technology is implemented to send targeted advertisements to individuals, then advertising effectiveness is improved, but user disturbance increases when users do not want to receive advertisements
Solution Approach 1:
The system proactively generates disruption signals before the advertisement signal can fully affect the user. The disruption signal is prepared and transmitted in advance to counteract the bone conduction advertisement, preventing user disturbance while maintaining advertising capability for those who want to receive it.
Solution Approach 2:
The disruption signal modifies key parameters of the advertisement signal, specifically frequency shifting and phase inversion. By changing these parameters, the system creates a counter-signal that cancels out the advertisement through destructive interference, effectively blocking unwanted advertisements while preserving the targeted delivery mechanism.
2Ease of operation
If disruption signals are generated to cancel bone conduction advertisements, then user control over advertisements is improved, but signal processing complexity increases
Solution Approach 1:
The system replaces complex mechanical or electronic signal blocking mechanisms with acoustic wave interference. Instead of using physical barriers or complex electronic filtering, the invention uses the principle of sound wave cancellation through phase inversion and frequency matching, simplifying the overall system architecture while maintaining user control capability.
Solution Approach 2:
The disruption signal acts as an intermediary between the user's control input and the advertisement signal. Rather than directly blocking the advertisement through complex processing, the system introduces this intermediate disruption signal that mediates the interaction, simplifying the control mechanism while achieving the desired user control over advertisements.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables users to effectively disrupt unwanted bone conduction advertisements, ensuring they are not disturbed by unwanted signals, thereby improving user control over their advertising experience.
Implementation Method 1
The disruption signal includes the signal after a frequency shift. The frequency shift may render the signal inaudible to the user.
Implementation Method 2
The disruption signal includes signal characteristics that are used to cancel at least a portion of the signal.
