Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Miniaturized alert devices in electronic devices are inadequate in noisy environments and can vary in response due to manufacturing tolerances, making it difficult to effectively alert users.
Innovation Solution
An electronic device that autonomously adapts user alerts by determining its operating environment using sensors and adjusting alert devices, such as vibration motors, to optimize alert effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If alert devices are miniaturized to conserve space in portable electronic devices, then device size is reduced, but alert effectiveness deteriorates in noisy environments
Solution Approach 1:
The patent implements dynamic adjustment of alert parameters including vibration frequency, amplitude, and duration based on real-time environmental sensing. The system transitions from static miniaturized alert components to dynamically adaptable alert delivery, modifying vibration patterns and selecting among multiple alert types (haptic, visual, auditory) to maintain effectiveness despite size constraints
Solution Approach 2:
The system changes physical parameters of the alert mechanism by adjusting vibration frequency and amplitude based on environmental conditions. Sensors detect ambient noise levels and other contextual factors, then the control system modifies alert parameters to optimize user perception while maintaining the miniaturized form factor
2Manufacturing precision
If manufacturing tolerances are reduced to improve device consistency, then manufacturing precision is improved, but device complexity and cost increase
Solution Approach 1:
The system performs self-characterization by automatically measuring its own alert device response characteristics during operation. Through feedback from sensors and actuators, the system builds a model of its specific hardware variations, enabling it to compensate for manufacturing tolerances without requiring external calibration or increased manufacturing precision
Solution Approach 2:
The patent implements feedback loops where sensors monitor the actual response of alert devices and feed this information back to the control system. This feedback enables real-time adjustment of alert parameters to account for manufacturing variations, replacing the need for tight manufacturing tolerances with adaptive control
3Adaptability or versatility
If multiple alert devices are provided to handle different environments, then alert versatility is improved, but device complexity increases
Solution Approach 1:
The system provides multi-functionality by integrating multiple alert mechanisms (haptic vibration motors, visual displays, auditory speakers) that can be selectively activated. Rather than requiring separate dedicated alert systems for different environments, a single universal alert subsystem can deliver multiple types of alerts through one integrated control architecture
Solution Approach 2:
The system dynamically selects and switches between different alert types based on environmental conditions. The control system evaluates sensor data and determines the most appropriate alert modality (vibration, light, sound) and pattern, providing environmental adaptability through dynamic decision-making rather than static configuration
