Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional glue logic (FGPA, CPLD, or FIFO) is used for microcontroller-camera interface, then image streaming capability is achieved, but device complexity and cost increase
Solution Approach 1:
The patent extracts and removes the complex glue logic components (FGPA, CPLD, FIFO) from the interface between camera and microcontroller. Instead of using these intermediate components, the invention directly interfaces the camera's parallel data output with the microcontroller's parallel data input, eliminating unnecessary complexity while maintaining image streaming capability.
Solution Approach 2:
The invention creates a universal interface approach that works with a wide range of microprocessors and microcontrollers without requiring device-specific glue logic. The direct parallel interface design is compatible with multiple microcontroller types, making the solution multi-functional and broadly applicable.
2Ease of manufacture
If conventional glue logic is used for camera interface, then image streaming is enabled, but manufacturing cost increases
Solution Approach 1:
The patent removes expensive discrete glue logic components from the interface design. By eliminating FGPA, CPLD, or FIFO components and using a direct parallel interface between camera and microcontroller, the manufacturing cost is significantly reduced while maintaining the same functional capability.
3Productivity
If low frame capture rate is used for diagnostic tests, then image acquisition efficiency is improved, but time to capture images increases
Solution Approach 1:
The patent implements periodic action by capturing images at predetermined time intervals rather than continuously. The microcontroller is configured to capture images at low frame rates (e.g., once per minute or less) based on the diagnostic test requirements, which optimizes efficiency for applications where continuous monitoring is not necessary.
