Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If virtual image data is generated based on sensing data from external sensing devices, then user immersion is improved, but device complexity increases
Solution Approach 1:
The patent introduces an intermediary processing system that receives sensing data from external devices, generates virtual image data, and transmits it to the image display device. This mediator handles the complex processing tasks separately, allowing the core AR device to remain relatively simple while still achieving high immersion through coordinated operation of multiple components.
Solution Approach 2:
The system integrates multiple functions into a coordinated framework: the communicator handles device identification and data transmission, the processor performs sensing data analysis and virtual image generation, and the image display device presents the augmented reality content. This multi-functional integration resolves the complexity-immersion contradiction by distributing capabilities across specialized components.
2Ease of operation
If the image display device is made compact and lightweight, then ease of operation is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent divides the AR system into separate functional modules: a compact lightweight image display device for user wear, an external sensing device for data collection, and a communication interface for coordination. This segmentation allows the wearable component to remain simple and comfortable while precision requirements are distributed to specialized external devices that can be larger and more complex.
Solution Approach 2:
The communication interface acts as an intermediary that coordinates between the compact image display device and external sensing devices. This mediator handles the complex synchronization and data processing tasks externally, allowing the wearable device itself to remain compact and lightweight without compromising manufacturing precision or functionality.
3Reliability
If virtual images are synchronized with actual images, then user immersion is improved, but processing time increases
Solution Approach 1:
The system performs preliminary actions by pre-identifying sensing devices and establishing communication channels before AR operation begins. The processor is pre-configured to receive and process sensing data from specific external devices, and the image display device is pre-synchronized with the sensing device timing. This preliminary setup reduces real-time processing requirements and enables faster synchronization during actual AR operation.
Solution Approach 2:
The system implements feedback mechanisms where the processor continuously receives sensing data, generates updated virtual image data, and transmits it to the image display device in real-time cycles. This feedback loop enables dynamic synchronization that adapts to changing conditions while maintaining immersion, with the processor adjusting virtual image positioning and content based on real-time sensing input from external devices.
