Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple sequential operations are used to control screens on multiple touch displays, then screen control functionality is achieved, but operation complexity increases and intuitiveness decreases
Solution Approach 1:
The patent merges multiple sequential touch operations into a single simultaneous multi-point touch operation. By detecting multiple touch points at the same time on different touch displays, the system can perform screen switching, scrolling, or other control functions across multiple displays in one action, rather than requiring sequential taps or flicks on each display individually.
Solution Approach 2:
The patent introduces a new dimension of control by utilizing the spatial distribution of multiple touch points across different touch displays simultaneously. The system analyzes the positions, numbers, and patterns of concurrent touch points to determine control actions, adding a spatial multi-dimensional aspect to the operation that enables more intuitive and efficient screen management.
2Productivity
If sequential tapping operations are performed on multiple touch displays to switch screens, then screen switching is achieved, but the number of operations increases
Solution Approach 1:
The patent combines multiple sequential screen switching operations into a single simultaneous multi-point touch operation. When users touch multiple touch displays at the same time with appropriate patterns, the system executes screen switching across all involved displays in one action, eliminating the time required for sequential operations and improving overall productivity.
Solution Approach 2:
The system prepares for efficient screen switching by pre-defining operation patterns and their corresponding actions. When multiple touch points are detected simultaneously, the system has already established the mapping between touch patterns and screen switching actions, enabling immediate execution without sequential processing delays.
3Ease of operation
If multiple flicking operations are performed to move multiple screens, then screen movement is achieved, but operation complexity and time increase
Solution Approach 1:
The patent merges multiple sequential flicking operations into a single simultaneous multi-point flick operation. By detecting the direction and velocity of multiple touch points moving simultaneously across different touch displays, the system can scroll or move screens on multiple displays in one coordinated action, reducing both operational complexity and time required.
Solution Approach 2:
The system utilizes the directional information from multiple simultaneous flicking motions as an additional dimension for control. By analyzing the vector directions and magnitudes of multiple moving touch points, the system determines appropriate screen movement actions across multiple displays, enabling intuitive control that reduces both time and complexity.

AI summary
Provided is a mobile terminal device that includes a plurality of touch displays and a control unit. The control unit associatively controls screens displayed on the plurality of touch displays based on the number of simultaneous operations and operation directions. The number of simultaneous operations is the number of touch operations simultaneously carried out and accompanied by the movement of touch positions, and the operation directions are directions in which the touch positions of the touch operations have moved.
