Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the flexible display slides at a constant speed based on on-going function, then the device operation is simple and stable, but the user experience is not adapted to various surrounding situations
Solution Approach 1:
The patent implements dynamic speed adjustment of the flexible display by transitioning from constant speed sliding to variable speed sliding based on detected surrounding situations. The processor adjusts the sliding speed in real-time according to sensor inputs (proximity, light, touch), making the system adaptive to different environments while maintaining manageable complexity through event-driven control logic.
Solution Approach 2:
The patent employs feedback mechanisms where sensors continuously monitor surrounding conditions (proximity, light intensity, touch input) and feed this information to the processor. The processor then adjusts the flexible display's sliding speed based on this feedback, creating a closed-loop control system that adapts to varying situations without requiring complex manual intervention.
2Speed
If the flexible display slides quickly to respond to events, then the response speed is improved, but the risk of damage to the display increases
Solution Approach 1:
The patent applies dynamic speed adjustment by varying the flexible display's sliding speed according to the specific situation. In normal operation, the display slides at moderate speeds to ensure durability. When urgent events are detected (such as drop detection or forced closure), the system accelerates the sliding speed to quickly protect the display, thus achieving both fast response and damage prevention through context-aware speed control.
Solution Approach 2:
The patent changes the speed parameter of the flexible display dynamically based on detected events and surrounding conditions. The processor modifies the sliding speed parameter in real-time, using slower speeds for routine operations to preserve display integrity and faster speeds for emergency protection scenarios, thereby balancing response speed with display durability through parameter adaptation.
3Ease of operation
If the flexible display adjusts sliding speed based on surrounding situations, then user convenience is improved, but the control system complexity increases
Solution Approach 1:
The patent achieves user convenience through a multi-functional control system that integrates multiple sensors (proximity, light, touch) and processes various event types (user input, environmental changes, emergency conditions) through a single unified processor. This universal approach allows the system to handle diverse situations with a cohesive control architecture, improving ease of operation while managing complexity through integrated rather than separate control mechanisms.
Solution Approach 2:
The patent implements self-service functionality where the flexible display system automatically adjusts its sliding behavior based on sensor inputs without requiring explicit user commands. The processor autonomously interprets surrounding situations and controls the display's motion accordingly, providing convenient adaptive behavior while keeping the control system relatively simple through rule-based automatic decision-making rather than complex user interfaces.
