Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual input of relative position information is used for each display device, then the system can be configured, but errors increase and setup complexity increases
Solution Approach 1:
The display devices automatically detect and acquire relative position information through the positioning signal without requiring manual input. Each display device self-configures by sensing the positioning signal from adjacent devices, eliminating human intervention in the position configuration process and thereby improving both accuracy and simplicity.
Solution Approach 2:
The patent replaces the manual mechanical input method (user typing position information through OSD interface) with an automated sensing system. The sensing unit detects electrical positioning signals transmitted through the video signal cable, substituting human operation with automatic electronic detection to improve accuracy and reduce complexity.
2Productivity
If manual input of relative position information is required, then configuration is possible, but time consumption increases
Solution Approach 1:
The positioning signal is pre-established in the video signal cable during system installation. The signal path is predetermined through the cascaded connection of display devices, allowing automatic detection without time-consuming manual configuration during setup operation.
Solution Approach 2:
Each display device automatically acquires its position information through the sensing unit detecting the positioning signal, eliminating the time required for manual input. The system self-configures upon power-up, significantly reducing setup time compared to manual configuration methods.
3Ease of operation
If automatic detection of relative position information is implemented, then setup complexity is reduced, but device complexity increases
Solution Approach 1:
The video signal cable serves multiple functions: transmitting video signals and carrying the positioning signal simultaneously. The positioning module and sensing unit are integrated into the existing display device architecture, allowing automatic position detection without adding separate dedicated wiring or complex external systems.
Solution Approach 2:
The positioning signal acts as an intermediary carrier that conveys position information through the existing video signal cable. This intermediary approach allows position information to be transmitted without requiring direct communication protocols or complex data exchange mechanisms between devices.
4Extent of automation
If positioning module and sensing unit are added to each display device, then automatic position detection is achieved, but manufacturing cost increases
Solution Approach 1:
The positioning module and sensing unit are integrated into the existing display device circuitry, sharing common components and signal paths. The video signal cable and processing circuits perform both video transmission and position detection functions, reducing the need for separate dedicated components and lowering manufacturing complexity.
Solution Approach 2:
The positioning signal transmission and video signal transmission are merged into the same cable and processing pathway. The sensing unit detects the positioning signal while the display control unit processes both video and position information through integrated circuits, combining multiple functions into unified system components to reduce manufacturing complexity.
