Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple display devices are connected to enable cooperative display, then user convenience and interaction capability are improved, but device complexity and processing load increase
Solution Approach 1:
The patent introduces a determination unit that acts as an intermediary to manage connections between display devices. This unit automatically determines which devices are connected and coordinates their interactions, shielding users from the underlying complexity while enabling cooperative display functionality.
Solution Approach 2:
The system dynamically adjusts the display configuration based on real-time connection status. When devices are connected, the determination unit activates cooperative display modes; when disconnected, it reverts to independent operation, allowing the system to adapt its complexity level to current usage conditions.
2Measurement precision
If virtual display regions are set across multiple devices, then contact position management accuracy is improved, but information transmission requirements and processing load increase
Solution Approach 1:
The patent divides the cooperative display system into distinct virtual display regions, each associated with specific physical positions on connected devices. This segmentation allows precise tracking of contact positions within each region while reducing the overall information transmission burden by localizing position data to specific segments rather than requiring global coordination.
3Adaptability or versatility
If connection determination between display devices is implemented, then cooperative display functionality is enabled, but system complexity and setup requirements increase
Solution Approach 1:
The determination unit implements self-service functionality by automatically detecting and determining connections between display devices without requiring manual configuration. The system autonomously identifies connected devices, establishes appropriate virtual display regions, and activates cooperative modes, eliminating the need for complex setup procedures.

AI summary
Provided is a display device that includes a first display unit, a determination unit, a virtual display region setting unit, a transmission unit, and a reception unit. The determination unit determines a connection with a different display device that includes a second display unit. The virtual display region setting unit sets, based on a determination that a connection with the different display device has been made, a second virtual display region with which each position of the second display unit is associated, in association with a first virtual display region with which each position of the first display unit is associated. The transmission unit transmits information regarding a first contact position of a first contact on the first display unit to the different display device. The reception unit receives information regarding a second contact position of a second contact on the second display unit from the different display device.
