Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If multiple devices are used for media reproduction to enhance vividness, then media reproduction quality is improved, but device synchronization control becomes more complex

Engineering Contradiction:
Improvemedia reproduction qualityVSAvoidsynchronization control complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent introduces a synchronization information table as an intermediary data structure that mediates between multiple devices and the control system. This table stores and manages synchronization information for each device, allowing the system to coordinate multiple devices without direct complex inter-device communication, thus improving media reproduction quality while managing synchronization complexity through a centralized information repository

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the parameter representation by extracting metadata from ne-media files that contains device control information. By encoding synchronization parameters directly in the media metadata, the system can control multiple devices using standardized parameter changes rather than device-specific control mechanisms, enhancing reproduction quality while simplifying the control architecture

Inventive Principle:
Principle #35Parameter changes

2Measurement precision

If metadata extraction from ne-media is performed to enable device control, then device mapping precision is improved, but information processing time increases

Engineering Contradiction:
Improvedevice mapping precisionVSAvoidinformation processing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent applies preliminary action by extracting and storing device control metadata from ne-media files in advance, before actual media reproduction occurs. The synchronization information table is constructed and prepared beforehand, containing all necessary device mapping and control information. This allows the system to achieve high device mapping precision without processing delays during actual playback, as the metadata extraction and analysis are completed in a preliminary setup phase

Inventive Principle:
Principle #10Preliminary action

AI summary

Provided is a system and method for controlling synchronization of media and multi-devices for an SMMD media service. The system includes a metadata managing unit and a synchronization controlling unit. The metadata managing unit analyzes ne-media to extract metadata. The synchronization controlling unit constructs a synchronization information table to store control data extracted from the metadata, and controls one or more devices for media reproduction on the basis of the synchronization information table. Optimal connectable devices are mapped according to device attributes and synchronization information extracted from metadata of ne-media and the results are controlled according to the contents of media, thereby maximizing the effect of vivid media reproduction.
