Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple processors are used to control a large number of display modules in a peer-to-peer method, then each display module can be controlled independently, but the cost and power consumption increase
Solution Approach 1:
Multiple display modules are merged into a single hierarchical control structure where one processor controls multiple modules through a daisy-chain connection. The processor transmits signals to the first display module, which then relays signals to subsequent modules, combining multiple control functions into a single processor unit.
Solution Approach 2:
Display modules serve as intermediaries in the signal transmission chain. The first display module receives signals from the processor and acts as a mediator to transmit control signals to the second display module, enabling the processor to control multiple modules without direct connections to each one.
2Reliability
If multiple processors are used to control display modules, then each module can be controlled independently, but the device complexity increases
Solution Approach 1:
The control function is merged into a single processor that manages multiple display modules through a hierarchical structure. Instead of having one processor per module, the system combines multiple control functions into one processor unit that communicates with modules in a daisy-chain arrangement.
Solution Approach 2:
The control architecture is segmented into a hierarchical structure with one processor at the top level and multiple display modules at the lower level. The signal transmission path is segmented through sequential connections, where each module receives signals from the previous module in the chain, reducing the need for multiple independent processors.
3Area of stationary object
If a processor processes resolutions greater than its mounted pixel capacity, then it can handle larger displays, but it cannot utilize the full specified capabilities of the processor
Solution Approach 1:
The display system is segmented into multiple modules that can be arranged in various configurations (series, parallel, or combination). This segmentation allows a single processor to control different numbers and types of modules depending on the required display resolution, enabling the processor to operate at or near its full capability for different display sizes.
Solution Approach 2:
The display module configuration is made dynamic and adaptable. The system can adjust the number and arrangement of display modules connected to the processor based on the required resolution and display area, allowing the processor to utilize its full specified capabilities across different operating scenarios rather than being fixed to a single configuration.
