Solution Overview

Problem

Users often miss important notifications, such as incoming calls or messages, in noisy environments because they cannot hear their mobile device's audible alerts, leading to frustration and dissatisfaction with their devices.

Innovation Solution

A computing device that predicts when a user will have difficulty hearing audible notifications due to environmental noise and automatically enables vibration notifications, optionally on connected devices like smartwatches, to ensure the user is alerted regardless of the noise level.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the user manually sets the ringtone on and vibration off, then the device complexity is reduced and ease of operation is improved, but the reliability of notification delivery deteriorates in noisy environments

Engineering Contradiction:

Improvemanual control simplicityVSAvoidnotification delivery

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system automatically monitors environmental noise levels and autonomously switches between audible and vibration notifications without requiring user intervention. The device serves itself by detecting noisy environments and activating vibration mode, eliminating the need for manual configuration while ensuring reliable notification delivery.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The notification system dynamically adapts its delivery method based on real-time environmental conditions. The system transitions from static manual configuration to dynamic automatic adjustment, switching between ringtone and vibration modes according to detected noise levels, thereby maintaining both ease of operation and reliability.

Inventive Principle:

Principle #15Dynamics

2Reliability

If the device automatically detects environmental noise and switches notification modes, then the reliability of notification delivery is improved, but the device complexity increases

Engineering Contradiction:

Improvenotification deliveryVSAvoidautomatic detection system

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The existing microphone and processor components are repurposed to perform dual functions: their primary functions remain unchanged while they also serve noise level detection for automatic notification mode switching. This multi-functionality approach adds reliability without requiring entirely new specialized components, thereby limiting the increase in device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If vibration notifications are always enabled, then the reliability of notification delivery is improved, but the use of energy increases

Engineering Contradiction:

Improvenotification deliveryVSAvoidvibration motor consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

Instead of continuous vibration motor operation, the system periodically monitors environmental noise levels and activates vibration mode only when needed. This periodic detection and conditional activation ensures reliable notification delivery in noisy environments while minimizing energy consumption by keeping the vibration motor off during quiet periods.

Inventive Principle:

Principle #19Periodic action

AI summary

A computing device supports both audible notifications and vibration notifications that are used to notify a user of various different events, such as an incoming voice call or text message. The computing device predicts when a user will have difficulty hearing an audible notification from the computing device due to environmental noise. In response to predicting that a user will have difficulty hearing an audible notification from the computing device due to environmental noise, the computing device enables vibration notifications (if not already enabled) on the computing device. The computing device also optionally communicates with one or more additional devices (e.g., a smartwatch or other wearable device) connected to the computing device to cause those additional devices to also enable vibration notifications. In response to subsequent events for which the user is to be notified, the computing device (and optionally additional devices connected thereto) provides a vibration notification.
