Solution Overview

Problem

Existing techniques for managing dynamically-available media playback and adapting visual outputs based on device capabilities are cumbersome and inefficient, often requiring multiple key presses, failing to account for device differences, and wasting user time and battery power.

Innovation Solution

Electronic devices are equipped with faster and more efficient methods and interfaces that adapt to device capabilities, reducing cognitive burden and conserving power by optimizing user inputs and visual outputs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If media content is pre-loaded onto the device before delivery, then the user experience is improved with continuous playback, but the device requires large storage capacity and consumes more energy

Engineering Contradiction:
Improvemedia playback continuityVSAvoiddevice storage capacity
Core Design Contradiction:
Duration of action of moving objectVSQuantity of substance

Solution Approach 1:

The media content delivery process is segmented into multiple phases: initial download of media information, selective downloading of media content based on user behavior, and progressive content delivery. This segmentation allows the system to avoid loading entire media libraries at once, reducing storage requirements while maintaining playback continuity for actively consumed content.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary actions by downloading and caching media information (metadata, indexes, playlists) before the actual media content is needed. This preliminary action enables the device to quickly access and begin playback of selected content without requiring full pre-loading of all media files, thus improving playback readiness while minimizing storage usage.

Inventive Principle:
Principle #10Preliminary action

2Duration of action of moving object

If media content is pre-loaded onto the device before delivery, then the user experience is improved with continuous playback, but the download time and network bandwidth consumption increase

Engineering Contradiction:
Improvemedia playback continuityVSAvoiddownload time
Core Design Contradiction:
Duration of action of moving objectVSLoss of time

Solution Approach 1:

The system downloads and caches media information (metadata, indexes, playlists, thumbnails) in advance before actual media playback is needed. This preliminary action prepares the device for rapid content access and selection, enabling users to start playback quickly without waiting for large media files to download, thus reducing perceived download time while maintaining playback continuity.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system downloads only the necessary portion of media content based on user behavior patterns and consumption habits. Instead of downloading entire media libraries, it selectively downloads content that is likely to be consumed, performing a partial action that suffices for the user's actual needs, thereby reducing total download time and network bandwidth consumption.

Inventive Principle:
Principle #16Partial or excessive action

3Ease of operation

If the device downloads and caches a large amount of media information, then media selection and playback are facilitated, but the device complexity and processing requirements increase

Engineering Contradiction:
Improvemedia selection capabilityVSAvoidinformation processing complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The media information structure is segmented into hierarchical levels: media information (metadata, indexes), media content (actual files), and media playlists (organized collections). This segmentation allows the device to process and manage information at appropriate granularities, reducing overall complexity while facilitating easy media selection through organized, manageable data structures that can be efficiently searched and displayed.

Inventive Principle:
Principle #1Segmentation

4Quantity of substance

If media content is delivered without pre-loading onto the device, then storage capacity is conserved, but interruptions may occur during playback

Engineering Contradiction:
Improvedevice storage capacityVSAvoidmedia playback continuity
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The system performs preliminary downloading and caching of media information and selected media content before playback is initiated. This preliminary action ensures that sufficient content is available locally to maintain continuous playback without interruptions, while the selective nature of the pre-loading (based on user behavior analysis) ensures that storage capacity is not unnecessarily consumed by unused content.

Inventive Principle:
Principle #10Preliminary action
