Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If audio content is modified based on device location and orientation, then the user's augmented reality experience is enhanced, but the device complexity increases due to additional location processing and orientation processing modules
Solution Approach 1:
The system is divided into distinct functional modules: a location processing module that handles position determination, an orientation processing module that handles device orientation, and an audio content modification module. This segmentation allows each module to specialize in specific tasks, improving overall system adaptability while managing complexity through modular design.
Solution Approach 2:
The device integrates multiple functions into a single system: location determination, orientation determination, and audio content modification all occur within the same device. This multi-functionality enhances the user experience by providing comprehensive augmented reality audio enhancement without requiring multiple separate devices.
2Measurement precision
If location processing module and orientation processing module are added to determine device position, then audio content modification accuracy is improved, but the device complexity increases
Solution Approach 1:
The determination process is segmented into two independent modules: location processing module for position determination and orientation processing module for orientation determination. This segmentation improves measurement precision by dedicating specialized modules to each task while managing complexity through functional separation.
Solution Approach 2:
The location processing module and orientation processing module act as intermediary components between the audio content and the modification process. These modules provide accurate position and orientation data that enable precise audio content modification without requiring the audio processing to directly handle complex determination algorithms.
3Adaptability or versatility
If audio content is modified based on device location and orientation, then the immersive audio experience is enhanced, but the processing time and computational resources increase
Solution Approach 1:
The system performs preliminary determination of device location and orientation before audio content modification. By obtaining position and orientation data in advance, the system prepares the necessary parameters for audio modification, reducing real-time processing delays and improving the overall responsiveness of the augmented reality audio experience.
