Engineering Contradiction Analysis
1Ease of operation
If conventional projection methods are used to project and return windows between electronic devices, then the projection function is achieved, but the user experience is poor due to cumbersome operations
Solution Approach 1:
The projection operation is segmented into distinct phases: initiation phase (drag from first device), transition phase (drag across boundary), and completion phase (drop on second device). Each phase has specific interaction rules that simplify user input while maintaining system control.
Solution Approach 2:
The system introduces an intermediary drag operation that acts as a mediator between the source device and target device. This intermediary mechanism handles the complex coordination of projection state changes, device communication, and window rendering without requiring users to manage these details directly.
2Productivity
If multiple steps are required to project and return windows, then precise control is achieved, but the operation becomes cumbersome and time-consuming
Solution Approach 1:
The system performs preliminary actions by pre-establishing communication channels between devices, pre-rendering projection windows, and pre-configuring projection parameters before the actual projection operation is triggered. This reduces the time required during the actual projection and return operations.
Solution Approach 2:
The projection operation maintains continuity by allowing the window to be dragged across device boundaries without interrupting the projection state. The system continuously updates the projection status and maintains visual feedback throughout the drag operation, eliminating gaps and interruptions that would increase operation time.
