Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If camera shooting or manual drawing methods are used to generate system-setting images, then the projection device can obtain basic images, but the diversity and adaptability of the images are limited
Solution Approach 1:
The patent pre-categorizes images into multiple theme databases (such as natural scenery, architecture, animals, plants, food, beverages) before actual use. When the projection device needs to project images, it first determines the surrounding environment theme and then selects from the corresponding pre-prepared database, avoiding the need for complex real-time image generation while ensuring adaptability to different environments.
Solution Approach 2:
The projection device automatically senses the surrounding environment and autonomously selects or generates appropriate theme images without requiring manual intervention. The device uses its built-in environment sensing module to detect environmental characteristics and automatically matches them with suitable images from the theme databases, enabling self-adaptive image selection.
2Adaptability or versatility
If multiple picture databases are stored to provide diverse images, then the adaptability improves, but the storage requirements and system complexity increase
Solution Approach 1:
The patent divides the image storage system into multiple independent theme databases, each containing images of a specific category (natural scenery, architecture, animals, plants, food, beverages). This segmentation allows the system to store images in an organized manner and quickly locate appropriate images based on the detected environment theme, improving both adaptability and retrieval efficiency.
Solution Approach 2:
The projection device is designed to handle multiple types of images through a unified system architecture. The environment sensing module can detect various environmental characteristics, and the image selection module can work with multiple theme databases simultaneously, making the system universally applicable to different projection scenarios without requiring separate systems for each image type.
3Ease of operation
If the projection device automatically senses and adapts to the surrounding environment, then the user experience improves, but the processing time and computational requirements increase
Solution Approach 1:
The system pre-categorizes images into multiple theme databases (such as natural scenery, architecture, animals, plants, food, beverages) before actual use. When the projection device needs to project images, it first determines the surrounding environment theme and then selects from the corresponding pre-prepared database, avoiding the need for complex real-time image generation while ensuring adaptability to different environments.
Solution Approach 2:
The projection device uses an environment sensing module to continuously monitor and detect environmental characteristics such as color, brightness, and surrounding objects. The detection results are fed back to the image selection module, which adjusts the selected images in real-time to match the detected environment, creating a closed-loop adaptive system that responds dynamically to environmental changes.
