Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If predetermined complementary processing is executed automatically when discharge abnormality occurs, then processing speed is improved, but image quality deteriorates due to suboptimal processing selection
Solution Approach 1:
The system dynamically adjusts the complementary processing method based on real-time user input and device characteristics. Instead of using a fixed predetermined processing, the system allows users to select from multiple complementary processing options (such as different nozzle replacement strategies or ink delivery adjustments) according to the specific discharge abnormality detected, thereby optimizing image quality while maintaining efficient processing.
Solution Approach 2:
The system changes processing parameters by offering multiple complementary processing variants that can be selected based on the specific discharge abnormality characteristics. The reception section receives user designations that modify the processing parameters (such as which nozzles to use as alternatives, how to redistribute ink delivery, or timing adjustments), allowing the execution section to adapt the complementary processing to match the specific abnormality condition and device characteristics.
2Manufacturing precision
If multiple complementary processing options are provided for user selection, then image quality is improved through optimal processing selection, but device complexity increases
Solution Approach 1:
The liquid discharge head is designed with multi-functionality by incorporating multiple nozzles that can serve different roles. When a discharge abnormality is detected in one nozzle, the system can universally utilize other nozzles from the same or different groups to compensate for the defective nozzle. The reception section and execution section work together to manage this multi-functional capability, allowing a single liquid discharge head to perform both normal discharge and complementary processing functions without requiring additional specialized components.
3Ease of operation
If automatic determination of complementary processing is implemented, then ease of operation is improved, but image quality deteriorates due to inability to account for specific device and liquid characteristics
Solution Approach 1:
The system implements a feedback mechanism where the determination section detects discharge abnormalities and provides information to the reception section, which then receives user designations based on that information. The execution section executes the complementary processing according to user input, and the results feed back into the system for continuous optimization. This feedback loop allows users to provide input based on their knowledge of specific device and liquid characteristics, ensuring high-quality image output while maintaining ease of operation through automated abnormality detection and processing execution.
