Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate signal processing board and T-Con board are used, then functional independence is improved, but resource utilization deteriorates and architecture cost increases
Solution Approach 1:
The patent merges the signal processing board and T-Con board into a single integrated SoC chip, combining previously separate functional units (image processing unit, display calibration unit, and storage unit) into one unified device. This integration enables resource sharing between units while maintaining functional independence through software-controlled task allocation, thereby improving resource utilization and reducing architecture cost without sacrificing functional capabilities.
Solution Approach 2:
The integrated SoC chip is designed with multi-functional units that can perform different operations based on control instructions. The image processing unit handles display tasks while the display calibration unit performs calibration, and both can access the shared storage unit. This universal design allows a single chip to replace multiple specialized boards, eliminating resource waste while preserving functional independence through software-based task management.
2Adaptability or versatility
If separate signal processing board and T-Con board are used, then functional independence is improved, but device complexity increases
Solution Approach 1:
The patent consolidates multiple separate boards into a single integrated SoC chip, reducing the number of physical components and interconnections. By combining the image processing unit, display calibration unit, and storage unit into one chip with a unified bus interface, the patent simplifies the overall system architecture while maintaining functional independence through software-controlled task allocation between units.
3Reliability
If dedicated storage units are allocated to each unit, then operational independence is improved, but resource utilization deteriorates
Solution Approach 1:
The patent implements a shared storage unit that serves both the image processing unit and the display calibration unit. The storage unit responds to control instructions from either unit to perform read or write operations, enabling dynamic resource allocation. This shared approach improves resource utilization by allowing both units to access the same storage resources when needed, while operational independence is maintained through software-controlled access management and control instruction routing.
