Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sound recording apparatuses cannot simultaneously operate the sound input unit and vibration control unit, leading to ineffective user interface feedback in noisy environments, such as large theme parks, where environmental noise interferes with vibration recognition.
Innovation Solution
An electronic apparatus comprising a user interface member, a vibrator, an environmental sound detector, and a controller that adapts the vibration frequency to suppress noise interference, allowing the user to recognize interface operations during sound recording by selectively determining drive modes for the vibrator based on environmental sound levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sound input unit is operated exclusively, then sound recording function is ensured, but the vibration control unit cannot be operated so user interface feedback is lost
Solution Approach 1:
The patent applies dynamics by making the vibrator's operational state adjustable rather than fixed. The controller dynamically changes the vibrator's drive state between different modes (normal vibration, suppressed vibration, or stopped vibration) based on real-time detection of environmental sound levels and recording states, allowing the system to adapt between sound recording reliability and user interface recognition needs
Solution Approach 2:
The patent changes the vibration parameter (vibration suppression) based on environmental conditions. The controller adjusts the vibration parameter by comparing environmental sound levels against thresholds and modifying the vibrator's operation accordingly, enabling the system to maintain sound recording quality while providing user feedback when environmental noise permits
2Ease of operation
If the vibrator operates at predetermined frequency, then user interface feedback is provided, but environmental noise interferes with sound recording
Solution Approach 1:
The patent implements feedback by using the environmental sound detector to continuously monitor environmental noise levels and feeding this information back to the controller. The controller then adjusts the vibrator's operation based on this feedback, creating a closed-loop system that adapts to environmental conditions to minimize noise interference while maintaining user interface functionality
Solution Approach 2:
The system dynamically adjusts the vibrator's operational state based on real-time environmental sound level detection. Rather than operating at a fixed predetermined frequency regardless of conditions, the vibrator's drive state changes dynamically according to environmental noise levels, allowing the system to reduce or suppress vibration when environmental noise is high
3Object-affected harmful factors
If vibration is suppressed according to environmental sound level, then noise interference is minimized, but user interface feedback may be reduced
Solution Approach 1:
The system dynamically adjusts the vibration suppression level based on environmental sound detection. When environmental noise is low, the vibrator operates normally providing full user feedback. When environmental noise increases beyond thresholds, the controller suppresses vibration to minimize noise interference. This dynamic adjustment ensures optimal balance between user interface recognition and noise minimization
Solution Approach 2:
The controller periodically evaluates environmental sound levels and adjusts vibrator operation in response. By continuously monitoring environmental noise and periodically modifying vibration output based on detected conditions, the system maintains appropriate user feedback while minimizing noise interference during sound recording
