Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual folding or unfolding of display screens is used, then the device structure remains simple, but user convenience deteriorates in special occasions or specific postures
Solution Approach 1:
The patent replaces the traditional mechanical rotary shaft system with a smart material-based actuating structure that responds to temperature changes. This substitution eliminates complex mechanical components while enabling automatic screen angle adjustment, thereby improving user convenience without proportionally increasing device complexity.
Solution Approach 2:
The patent utilizes temperature as a controllable parameter to drive the actuating structure. By changing the temperature of the smart material through current input, the system achieves automatic adjustment of screen angles, transforming a manual mechanical operation into an automated thermally-driven process.
2Ease of operation
If automated actuating structure is introduced, then user convenience improves, but device complexity increases
Solution Approach 1:
The patent extracts the core functionality of angle adjustment from the complex mechanical rotary shaft system and implements it through a simplified actuating structure based on smart materials. This extraction reduces the overall structural complexity while maintaining the essential automated adjustment capability.
Solution Approach 2:
The patent employs flexible display screens and thin-film-based actuating structures that can deform in response to temperature changes. This approach allows for automated screen angle adjustment without requiring rigid mechanical components, thereby reducing structural complexity.
3Measurement precision
If multiple angle sensors are arranged at intervals, then angle detection precision improves, but device complexity increases
Solution Approach 1:
The patent divides the angle sensing function into multiple discrete sensors arranged at specific intervals along the display screen. This segmentation allows for precise measurement of screen angles at different positions while maintaining a modular and manageable sensor configuration.
