Solution Overview

Problem

Existing audio playback systems lack a convenient method to modify audio output, such as pausing or muting alarms, without requiring direct user interaction, especially in scenarios where the user is groggy or needs to snooze an alarm.

Innovation Solution

Incorporating proximity sensors in playback devices that detect hand movement to trigger snooze features, allowing users to modify audio output by waving their hand over the device without touching it, and configuring options through a controller for different audio sources.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If proximity sensors are added to detect hand movement for triggering snooze features, then user convenience is improved, but device complexity increases

Engineering Contradiction:
Improveuser convenienceVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces mechanical button pressing with proximity-based detection. The proximity sensor detects hand movement and triggers audio modification (snooze, pause, mute) without requiring physical contact or button presses, thereby improving ease of operation while adding only minimal sensor-based functionality to the device.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If proximity sensors and automatic detection features are integrated, then ease of operation is improved, but manufacturing cost increases

Engineering Contradiction:
Improveease of operationVSAvoidmanufacturing cost
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The patent substitutes mechanical interaction (button presses) with optical/electromagnetic field-based proximity detection. This allows the system to gain advanced ease of operation features while avoiding complex mechanical assemblies, thereby controlling manufacturing costs despite adding sensor functionality.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If multiple audio modification options are configured for different audio sources, then adaptability is improved, but device complexity increases

Engineering Contradiction:
ImproveadaptabilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal proximity-based control mechanism that works across multiple audio sources and modification types (snooze, pause, mute, volume reduction). A single proximity sensor system handles diverse audio modification scenarios, improving adaptability without proportionally increasing device complexity through multiple specialized components.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

Embodiments described herein provide for detecting movement in proximity to a playback device and responsively modifying the audio that is output from one or more playback devices. According to an embodiment, a user is able to wave his or her hand over a playback device to modify the audio that is output from the playback device, one or more different playback devices, or all of the playback devices. The embodiments are particularly useful as a snooze feature, in which an alarm from a playback device (or group of playback devices) is snoozed for a time when triggered by the user's movement.
