Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If speakers amplify sound, then sound output is improved, but vibrations interfere with microphones, cameras, and touch screens
Solution Approach 1:
The patent introduces vibration mitigators as intermediary elements positioned between the speakers and other components (microphones, cameras, touch screens). These mitigators absorb and dampen vibrations generated by speakers, preventing them from interfering with the performance of sensitive components while allowing speakers to continue amplifying sound effectively.
Solution Approach 2:
The patent converts the harmful vibrations generated by speakers into a beneficial solution by using vibration mitigators to absorb these vibrations. The mitigators transform the mechanical energy of unwanted vibrations into heat through internal friction, thereby eliminating the harmful effect while maintaining speaker performance.
2Object-affected harmful factors
If vibration mitigators are added, then vibration interference is reduced, but device complexity increases
Solution Approach 1:
The patent employs vibration mitigators in the form of flexible dampening materials that can be integrated into the device housing or component mounts. These thin film or flexible structures provide vibration absorption without requiring complex mechanical assemblies, thereby reducing the impact on device complexity while effectively mitigating vibration interference.

AI summary
Voice activated electronic devices are described herein. In some embodiments, the voice activated electronic device may include a housing forming a cavity. An array of microphones, one or more speakers, and one or more cameras may be located within the cavity. Furthermore, the voice activated electronic device may include a display screen and a touch screen, which may both be coupled to the housing such that the housing is substantially enclosed. In some embodiments, the array of microphones is positioned about the housing such that audio input may be detectable from audio output by the speaker(s) while the speaker(s) are outputting audio. For instance, one or more vibration mitigators may be included to dampen vibrations that may affect a performance and functionality of the one or more components located within the cavity.
