Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual testing methods are used to evaluate media devices, then testing can be performed with simple equipment, but the testing process becomes slow and labor-intensive
Solution Approach 1:
The patent uses test files that are copies of media content to be tested, allowing automated playback and analysis without manual intervention. The testing system creates virtual copies of user interactions through test scripts, enabling rapid repeated testing while maintaining equipment simplicity.
Solution Approach 2:
The patent replaces manual mechanical testing operations with automated electronic systems. Test scripts automatically control media playback, and computer algorithms automatically analyze test results, substituting human operators and manual procedures with automated software-based solutions.
2Measurement precision
If comprehensive performance data collection is implemented, then device evaluation becomes more accurate and objective, but the complexity of the testing system increases
Solution Approach 1:
The patent divides the testing system into modular components: test file generation module, media playback module, data collection module, and analysis module. Each component handles a specific aspect of testing, allowing comprehensive data collection while maintaining manageable system complexity through clear separation of functions.
Solution Approach 2:
The patent introduces test files as intermediary elements between the testing system and the media device under test. These test files serve as standardized mediators that enable consistent, repeatable testing while simplifying the interaction between the testing system and various media devices.
3Adaptability or versatility
If frequent firmware changes are made to media devices, then device functionality and performance can be improved, but the need for retesting increases and extends certification time
Solution Approach 1:
The patent implements periodic automated testing that can be executed at regular intervals or triggered by firmware update events. The system performs repeated test cycles using the same test files, enabling rapid verification of firmware changes without requiring complete retesting, thus reducing recertification time while maintaining device adaptability.
4Reliability
If automated test scripts are used to mimic user commands, then testing becomes more objective and repeatable, but the initial setup and configuration becomes more complex
Solution Approach 1:
The patent creates universal test scripts that can be applied to multiple media devices and firmware versions. The test scripts are designed to work across different device types and scenarios, reducing the need for device-specific configuration while maintaining objective and repeatable testing through standardized automated procedures.
Data Source
AI summary
In accordance with an embodiment, described herein is a system and method for testing and certification of media devices for use within a connected media environment. A testing device includes an input mechanism, for example a microphone, and a plurality of test files. Each test file can be used to produce a characteristic signal, for example an audio track having a particular frequency. The testing device emulates a gateway between a media device under test, such as an audio speaker, and a media server. Test scripts can be used to mimic commands to play or otherwise access media content at the device under test. Playback of a particular test file can be detected and recognized according to the characteristic signal produced by that test file. Resultant test information can be used to evaluate the performance and/or certify operation of the media device within the connected media environment.
