Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a wearable device uses a camera to identify external electronic devices in real-time, then user interaction capability is improved, but processing complexity and power consumption increase
Solution Approach 1:
The system performs preliminary actions by capturing images continuously and preparing identification data before actual interaction is needed. The camera captures images of external devices, and the processor begins analyzing these images to identify devices and their optical signals, so that when interaction is required, the identification is already complete or near-complete.
Solution Approach 2:
The patent introduces an intermediary processing layer that includes image capture, identification, and coordinate mapping. The camera captures images, the processor identifies external devices and their optical signals, converts coordinates between camera and display systems, and generates visual objects. This intermediary processing chain manages complexity by breaking down the overall task into manageable stages.
2Measurement precision
If the wearable device maps optical signal positions from external devices to the display screen, then visualization accuracy is improved, but computational requirements increase
Solution Approach 1:
The system changes parameters by transforming coordinates from the camera's coordinate system to the display screen's coordinate system. The processor obtains coordinates of optical signals in the captured image and converts these to corresponding positions on the display screen, allowing accurate mapping while managing computational load through parameter transformation.
Solution Approach 2:
The patent creates a visual copy or representation of the external device and its optical signals on the display screen. Instead of directly processing complex spatial relationships, the system generates visual objects that replicate the position and appearance of external devices and their optical signals, making the information accessible and accurate without requiring continuous complex calculations.
3Reliability
If the device displays visual objects based on external device positions, then user immersion in augmented reality is improved, but display processing load increases
Solution Approach 1:
The system performs partial action by generating visual objects only for identified external devices and their optical signals, rather than processing all possible elements in the field of view. The processor identifies specific external electronic devices, locates their optical signals, and generates corresponding visual objects, avoiding unnecessary processing of irrelevant areas.
Solution Approach 2:
The patent segments the display processing into distinct stages: image capture from camera, identification of external devices, location of optical signals within those devices, coordinate transformation, and generation of visual objects. This segmentation allows each stage to be optimized independently and reduces the overall processing load by breaking down the complex task of augmented reality display into manageable components.
