Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the mobile terminal uses a small screen to maintain portability, then the portability is improved, but the convenience of using advanced functions like internet browsing and content editing deteriorates
Solution Approach 1:
The patent introduces a cradling stand as an intermediary device between the mobile terminal and external display devices. The stand enables the mobile terminal to offload display and input tasks to external devices, allowing users to enjoy advanced functions on larger screens while maintaining the portability benefits of a compact mobile terminal.
2Volume of moving object
If the mobile terminal uses a limited battery capacity to maintain compact size, then the compactness is improved, but the duration of using advanced functions deteriorates
Solution Approach 1:
The patent extracts the power-consuming display and input functions from the mobile terminal to external display devices. By offloading these functions, the mobile terminal's battery is preserved for core operations, extending the duration of advanced function usage without increasing the terminal's size.
3Device complexity
If the mobile terminal has limited compatibility with external devices to maintain simplicity, then the simplicity is improved, but the versatility of multi-screen services deteriorates
Solution Approach 1:
The cradling stand is designed with universal compatibility to work with various mobile terminals and external display devices. It provides multiple functions including display output, input device control, and multi-screen service coordination, enabling versatile external device integration without complicating the mobile terminal's core design.
