Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual configuration of touch displays is performed by users, then flexibility in configuring display settings is achieved, but the process becomes time-consuming and error-prone especially for novice users
Solution Approach 1:
The system performs automatic configuration of touch displays without requiring user intervention. The digitizer control module automatically detects adjacent displays, computes their relative positions, and configures them as a combined display, allowing the system to serve itself rather than requiring manual user configuration
Solution Approach 2:
The system performs detection and computation of relative positions as preliminary actions before the actual display configuration is needed. By pre-detecting the presence and position of adjacent displays, the system prepares the configuration data in advance, enabling seamless automatic setup when displays are connected
2Ease of manufacture
If manual alignment of multiple touch displays is performed, then display configuration is achieved, but alignment inaccuracies occur that are not easily visible during installation
Solution Approach 1:
The system replaces manual mechanical alignment procedures with an automatic detection and computation system. Instead of relying on visual inspection and manual adjustment during installation, the digitizer control module uses signal detection and computational algorithms to automatically determine precise relative positions, substituting mechanical alignment processes with electronic detection and software-based positioning
3Measurement precision
If automatic detection of adjacent displays is implemented, then alignment accuracy is improved, but device complexity increases due to additional detection and computation functions
Solution Approach 1:
The digitizer control module performs multiple functions: it detects touch inputs on the display, detects signals from adjacent displays, computes relative positions, and manages display configuration. By making this single component multi-functional, the system achieves automatic alignment without adding separate dedicated hardware components, thereby reducing overall system complexity while maintaining high measurement precision

AI summary
A computing device has a digitizer control module configured to monitor signals received by receive electrodes and to detect in the monitored signals a signal from a second touch display of a second computing device in physical proximity to the computing device. The digitizer control module is configured to determine one or more locations on the first touch display at which the signals from the second touch display are received. A processor in the computing device is configured to compute a relative position of the second touch display with respect to the first touch display on the basis of the determined locations, and to use the computed relative position to treat the first touch display and the second touch display as a combined touch display.
