Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a common power supply is used for both image processing unit and image output unit, then device complexity is reduced, but power management precision deteriorates
Solution Approach 1:
The patent segments the power supply system into two independent power supplies: a first power supply for the image processing unit and a second power supply for the image output unit. This segmentation allows each power supply to be controlled independently based on the operational state and data type, resolving the contradiction by providing both structural simplicity (through modular design) and control precision (through independent management).
Solution Approach 2:
The patent implements dynamic power supply control where the power state of each unit is adjusted based on real-time operational conditions. The control unit determines whether to supply power to the image output unit by analyzing data types and operational states, enabling flexible and precise power management that adapts to changing system requirements.
2Measurement precision
If two separate power supplies are provided for image processing unit and image output unit, then power management precision is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by using a single control unit that manages both power supplies. The control unit performs multiple functions: determining data types, assessing operational states, and controlling both the first and second power supplies based on comprehensive system state analysis. This multi-functional control approach simplifies the overall system architecture while maintaining precise power management.
Solution Approach 2:
The patent merges the control functions for both power supplies into a single control unit that operates the image processing apparatus. This consolidation of control functions reduces the complexity of having two independent control systems while preserving the precision benefits of separate power supplies, as the unified control unit coordinates both power supplies based on overall system requirements.
3Ease of operation
If power supply is controlled based on a single control instruction, then ease of operation is maintained, but power supply reliability deteriorates
Solution Approach 1:
The patent implements feedback mechanisms where the control unit continuously monitors operational states and data types to dynamically adjust power supply decisions. The control unit receives information about the current state of the image processing unit and image output unit, and uses this feedback to determine the appropriate power state for each unit, ensuring reliable power management while maintaining ease of operation through automated decision-making.
Solution Approach 2:
The control unit performs preliminary analysis of data types and operational states before making power supply decisions. By evaluating the nature of the data and the current operational state in advance, the control unit can proactively determine the appropriate power configuration, preventing power supply issues before they occur and ensuring reliable operation without requiring complex real-time adjustments.
