Solution Overview

Problem

Conventional audio file players face challenges in efficiently searching and selecting audio files due to limited display size and increasing storage capacity, requiring users to remember detailed information and play audio files from the beginning to confirm identification, which is time-consuming and inconvenient.

Innovation Solution

An apparatus and method that extracts the structure of song lyrics using a repeated pattern to create a tree structure, allowing for the extraction of thematic portions of audio files, reducing the time required to select audio files by arranging interlude sections, character strings, and paragraphs in a tree structure for quicker retrieval.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If users search for audio files by playing from the beginning portion to confirm identification, then they can accurately identify the desired audio file, but it takes a lot of time

Engineering Contradiction:
Improveaudio file identification accuracyVSAvoidtime to identify audio file
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent extracts the prelude portion (introductory section) from the audio file and uses it to generate a fingerprint. This extracted portion contains unique characteristics that can identify the audio file without requiring playback of the entire file from the beginning, thus reducing identification time while maintaining accuracy

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system performs preliminary analysis of the prelude portion to generate a fingerprint before the user needs to identify the audio file. This pre-computed fingerprint is then used for rapid comparison and identification, eliminating the need to play through the beginning of each file during the selection process

Inventive Principle:
Principle #10Preliminary action

2Volume of moving object

If the display window size is decreased for miniaturization, then the device size is reduced, but selecting a song title by manipulating buttons becomes inconvenient

Engineering Contradiction:
Improvedevice sizeVSAvoidease of selecting song title
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The patent replaces the mechanical button manipulation system with an acoustic recognition system. Instead of requiring users to physically navigate through small display buttons, the system uses speech recognition to identify and select audio files, making operation convenient regardless of display size

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

Solution Approach 2:

The patent introduces speech recognition as an intermediary between the user and the audio file selection process. The speech recognition system acts as a mediator that translates user speech into file selection commands, eliminating the need for direct manipulation of the small display interface

Inventive Principle:
Principle #24Intermediary (Mediator)

3Quantity of substance

If the storage capacity is increased to store more audio files, then the data storage capability is improved, but it takes longer to retrieve desired audio files

Engineering Contradiction:
Improvenumber of audio files storedVSAvoidspeed of retrieving audio file
Core Design Contradiction:
Quantity of substanceVSProductivity

Solution Approach 1:

The patent creates a fingerprint copy of the prelude portion for each audio file and stores this fingerprint in a database. During retrieval, users provide a reference fingerprint that is compared against the stored fingerprints, enabling rapid identification of matching files without scanning through the entire music library

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The system performs preliminary processing to generate and store fingerprints for all audio files in advance. This pre-computation allows for rapid comparison and retrieval operations, as the system only needs to compare fingerprints rather than analyze entire files during the retrieval process

Inventive Principle:
Principle #10Preliminary action
