Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing devices that adjust song reproduction tempo to match user exercise tempo often cause discomfort due to the inability to seamlessly adapt fast or slow tempos, limiting the use of personal favorite songs with varying tempos and restricting exercise load patterns.

Innovation Solution

A content reproduction list generation device that allows users to select and adjust song reproduction tempo change patterns, generating a list that synchronizes song reproduction order and tempo with user-defined exercise load patterns, enabling intuitive and flexible exercise guidance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the reproduction tempo of a song is increased to match the user's exercise tempo, then the exercise guidance effectiveness is improved, but a sense of discomfort may be invoked

Engineering Contradiction:

Improveexercise guidance effectivenessVSAvoidsense of discomfort

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The system dynamically adjusts the reproduction tempo of songs based on the user's exercise tempo detection, allowing the music playback speed to change in real-time during exercise. This enables the music to adapt to the user's motion state while maintaining comfort through gradual and controlled tempo changes.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the reproduction tempo parameter of songs to match the detected exercise tempo. By adjusting this key parameter, the system aligns the music rhythm with the user's exercise pace, improving guidance effectiveness while managing comfort through controlled parameter transitions.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If the reproduction tempo of a song is decreased to match the user's exercise tempo, then the exercise guidance effectiveness is improved, but a sense of sluggish movement may be invoked

Engineering Contradiction:

Improveexercise guidance effectivenessVSAvoidsense of sluggish movement

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The system dynamically adjusts the reproduction tempo downward when the user's exercise tempo is slower than the original song tempo. This dynamic adjustment allows the music to match the user's pace while maintaining engagement through controlled tempo reduction rather than static playback.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system modifies the reproduction tempo parameter to decrease the playback speed of songs, aligning them with the user's slower exercise tempo. This parameter adjustment ensures the music remains synchronized with exercise pace without creating a sluggish feeling through managed transition rates.

Inventive Principle:

Principle #35Parameter changes

3Object-affected harmful factors

If fixed-tempo songs are collected for fitness exercises, then a sense of comfort is avoided, but personally owned favorite songs with various tempos cannot be fully utilized

Engineering Contradiction:

Improvesense of comfortVSAvoidsong utilization flexibility

Core Design Contradiction:

Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The system changes the reproduction tempo parameter of personally owned favorite songs to match the user's exercise tempo in real-time. This allows any song regardless of its original tempo to be adapted for exercise purposes, eliminating the need for fixed-tempo song collections while maintaining comfort through dynamic adjustment.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The system makes the music playback function universal by enabling any song in the user's collection to be adapted for exercise use. Through automatic tempo adjustment, the system allows favorite songs with various original tempos to serve the same exercise guidance function, maximizing song utilization flexibility.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Adaptability or versatility

If the song reproduction tempo is automatically changed to match exercise tempo, then exercise guidance effectiveness is improved, but the user cannot impose a predetermined exercise load pattern

Engineering Contradiction:

Improveexercise guidance effectivenessVSAvoidexercise load control

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system provides dynamic tempo adjustment capabilities that can operate in different modes: automatic adjustment to match detected exercise tempo, or manual adjustment according to predetermined exercise load patterns. This dynamic flexibility allows users to switch between automatic and manual control based on their exercise needs.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system detects the user's exercise tempo and provides feedback for automatic tempo adjustment, while also allowing users to set predetermined tempo patterns for controlled exercise loads. The feedback mechanism enables both automatic adaptation and manual pattern imposition, combining effectiveness with exercise load control.

Inventive Principle:

Principle #23Feedback

AI summary

A content reproduction list generation device includes an operation section, a storage section, and a reproduction list generation section. The storage section is configured to store a change pattern indicating reproduction tempo changes during content reproduction. The reproduction list generation section is configured to specify a change pattern in accordance with an input into the operation section, associate content with the specified change pattern, and generate a content reproduction list for informing a reproduction section of the reproduction order and reproduction tempo of content to be reproduced in accordance with the specified change pattern and the associated content.
