Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual adjustment of image pickup and display parameters is performed for different camera and monitor types, then compatibility across different apparatus types can be achieved, but the adjustment process becomes time-consuming and complex
Solution Approach 1:
The patent applies preliminary action by pre-storing optimal parameter settings in a lookup table during the manufacturing process. Each camera and monitor type has its parameters (such as HSYNC timing, VSYNC timing, data signal timing) pre-adjusted and stored in association with identification data. When components are connected, the system automatically retrieves the pre-stored parameters based on identification data, eliminating the need for time-consuming manual adjustment during deployment.
2Manufacturing precision
If manual parameter adjustment is performed to optimize image quality for different apparatus configurations, then image quality can be optimized, but the complexity of the adjustment process increases
Solution Approach 1:
The patent applies self-service by enabling the system to automatically select and apply optimal parameters without requiring operator intervention. The control unit automatically reads identification data from connected cameras and monitors, retrieves corresponding optimal parameters from the stored table, and applies them automatically. This self-service mechanism maintains high image quality while eliminating the complexity of manual parameter adjustment processes.
3Reliability
If different parameter settings are used for different apparatus types to ensure optimal operation, then operational reliability is improved, but the number of parameters that must be managed increases
Solution Approach 1:
The patent applies the extraction principle by separating the complex parameter management into two distinct parts: (1) a pre-configured lookup table that stores optimal parameters for different apparatus types, and (2) an automatic retrieval mechanism that matches identification data with corresponding parameters. This extraction eliminates the need for operators to manually manage multiple parameter sets, as the system automatically extracts and applies the appropriate parameters based on connected device identification.
4Ease of operation
If automated parameter setting is implemented using identification data and stored tables, then adjustment time is reduced and ease of operation is improved, but the device complexity increases due to additional hardware components
Solution Approach 1:
The patent applies merging by integrating the parameter storage table and retrieval logic directly into the semiconductor device that controls the camera. The control unit, identification data storage, and parameter lookup table are combined into a single integrated component. This merging eliminates the need for separate external adjustment devices or complex external configuration systems, achieving automation while minimizing the increase in overall device complexity.
