Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If text-guided video generation is used, then creativity and ease of operation are improved, but manufacturing precision and measurement precision of object motion are insufficient
Solution Approach 1:
The patent segments the video generation process into distinct controllable components: content information (text/image), position information (starting frame object locations), and control information (ending frame constraints). This segmentation allows users to independently control each aspect, achieving both ease of operation through modular input and precision through specific parameter control for object motion.
2Manufacturing precision
If motion control is added to text-guided video generation, then manufacturing precision of object motion is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal video generation system that handles multiple input types (text and images) through a single integrated process. The system universally processes content information, position information, and control information regardless of the specific input modality, reducing complexity by avoiding separate specialized systems for each function.
Solution Approach 2:
The patent introduces position information as an intermediary element that bridges content information and control information. This intermediary structure organizes the complex data flow by first identifying object positions in the starting frame, then applying ending frame constraints, making the overall system more manageable and less complex.
3Manufacturing precision
If precise motion control parameters are required, then manufacturing precision is improved, but ease of operation deteriorates
Solution Approach 1:
The patent performs preliminary action by first obtaining position information that identifies object locations in the starting frame before applying control constraints. This preliminary step establishes a clear reference framework that simplifies subsequent control operations, making precision control more intuitive and easier to operate.
Solution Approach 2:
The patent applies local quality by allowing different levels of control precision for different aspects of video generation. Users can provide detailed position and control information specifically for objects requiring precise motion control, while other elements can be generated with standard text-guided controls, optimizing ease of operation where precision is not critical.
