Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the projector projects multiple images in multi-view mode without considering projection surface features, then the device complexity is reduced, but the image quality (resolution and aspect ratio) deteriorates
Solution Approach 1:
The system performs preliminary analysis of the projection surface features (obstacles, boundaries, shape) before projecting images. The processor captures an image of the projection surface, identifies feature information including obstacles and boundaries, and pre-calculates the optimal layout for multiple images. This preliminary action enables the projector to adjust the layout information of plurality of screens according to the identified features, ensuring high image quality without requiring complex real-time adjustments during projection.
Solution Approach 2:
The projector automatically performs multi-view mode projection by utilizing its own imaging capabilities to analyze the projection surface. The system captures images using the projector's imaging unit, processes the captured images to identify surface features, and autonomously determines the optimal layout for multiple images. This self-service approach eliminates the need for external configuration devices, maintaining device simplicity while achieving high-quality multi-view projection.
2Adaptability or versatility
If the projector adapts to different projection environments by identifying surface features, then the adaptability is improved, but the measurement precision requirements increase
Solution Approach 1:
The projector integrates multiple functions into a single device: it serves as both the projection device and the imaging device for surface analysis. The imaging unit can capture images of the projection surface to identify features such as obstacles, boundaries, and shape characteristics. This universal approach allows the same device to perform both projection and surface analysis, enhancing adaptability to different environments without requiring separate measurement instruments with high precision requirements.
Solution Approach 2:
The system implements a feedback mechanism where the projector captures images of the projection surface, identifies feature information including obstacles and boundaries, and uses this feedback information to adjust the layout of multiple images in real-time. The processor continuously monitors the projection environment and modifies the projection layout accordingly, enabling the system to adapt to various projection surfaces and obstacle configurations without requiring extremely precise initial measurements.
3Loss of information
If the projector uses fixed layout for multiple images, then the device complexity is reduced, but the loss of information increases due to suboptimal resolution and aspect ratio
Solution Approach 1:
The system transitions from a fixed layout approach to a dynamic layout system that adapts to the projection environment. The processor determines layout information for multiple images based on identified surface features such as obstacles, boundaries, and shape characteristics. This dynamic adjustment allows the projector to optimize resolution and aspect ratio for each image according to the actual projection conditions, minimizing information loss without requiring overly complex predetermined configuration systems.
