Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by stationary object
If the entire pixel array is updated simultaneously, then the update process is simple, but power consumption increases significantly
Solution Approach 1:
The pixel array is divided into multiple sections that can be updated independently. Each section has its own programming signals, allowing selective updates of only the necessary sections rather than the entire array, thereby reducing power consumption while maintaining manageable complexity through systematic segmentation.
Solution Approach 2:
The system dynamically selects which sections to update based on current needs, transitioning from static simultaneous updates to dynamic selective updates. This allows the system to adapt the update scope to actual requirements, minimizing power consumption during partial updates while maintaining simplicity for full array updates when necessary.
2Productivity
If independent programming signals are provided for each section, then segment programming efficiency improves, but the number of programming signals increases
Solution Approach 1:
The pixel array is divided into multiple sections that can be updated independently. Each section has its own programming signals, allowing selective updates of only the necessary sections rather than the entire array, thereby reducing power consumption while maintaining manageable complexity through systematic segmentation.
Solution Approach 2:
The programming signal structure is designed to serve multiple functions: it can program individual sections, multiple sections, or the entire array depending on activation patterns. This multi-functionality reduces the need for separate dedicated signals for each programming scenario, managing complexity while maintaining efficiency.
3Use of energy by stationary object
If dual programming signals are used in rows and columns, then power consumption during updates is minimized, but the control complexity increases
Solution Approach 1:
The system dynamically selects which sections to update based on current needs, transitioning from static simultaneous updates to dynamic selective updates. This allows the system to adapt the update scope to actual requirements, minimizing power consumption during partial updates while maintaining simplicity for full array updates when necessary.
Solution Approach 2:
The dual programming signal system is pre-configured with row and column assignments, allowing the control logic to operate with predetermined patterns. This preliminary arrangement simplifies real-time control decisions, reducing operational complexity while enabling power-efficient selective updates through the established signal framework.
