Solution Overview

Problem

Users face challenges in selecting media content that complements their repetitive motion activities, such as running, biking, or swimming, as traditional media-playback devices cannot match the tempo of the music with the user's cadence, affecting performance and enjoyment.

Innovation Solution

A media-playback device that includes a physiological measurement device to measure heart rate and a control engine to adjust the tempo of media content items based on the user's heart rate, ensuring synchronization with their cadence.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional media-playback devices are used to play media content during repetitive motion activities, then users can access large catalogs of media content, but the tempo of the media content cannot be matched with the user's cadence

Engineering Contradiction:

Improvetempo matching capabilityVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The media playback device automatically measures the user's physiological attributes (heart rate, cadence) and autonomously adjusts the tempo of media content to match the user's movement rhythm, eliminating the need for manual intervention while achieving adaptive tempo matching

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system dynamically changes the tempo parameter of media content based on real-time physiological measurements, allowing the media playback to adapt to the user's varying cadence and heart rate during exercise activities

Inventive Principle:

Principle #35Parameter changes

2Ease of operation

If physiological measurement devices and control engines are added to match media tempo with user cadence, then user experience and performance are improved, but device complexity increases

Engineering Contradiction:

Improveuser experienceVSAvoiddevice complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines the media playback device with physiological measurement capabilities and an integrated control engine into a single unified system, eliminating the need for separate external devices and simplifying the overall setup for the user

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The media playback device is enhanced to perform multiple functions: playing media content, measuring physiological attributes (heart rate, cadence), and automatically adjusting playback tempo, making it a multi-functional device that serves both entertainment and exercise monitoring purposes

Inventive Principle:

Principle #6Universality (Multi-functionality)
