Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display size is increased to accommodate multimedia services, then the user experience for multimedia functions is improved, but the device size increases and portability is compromised
Solution Approach 1:
The patent implements a flexible display that can dynamically change its configuration between extended and retracted states. The display transitions from a compact folded state for portability to an extended state for enhanced viewing area, allowing the device to adapt its display characteristics based on usage context rather than being fixed in one configuration
Solution Approach 2:
The flexible display is configured to nest within itself when retracted, with the second display area folding back onto the first display area. This nesting arrangement allows the display to occupy minimal space when not in full use while still providing a large display area when extended, effectively solving the contradiction between display size and device compactness
2Adaptability or versatility
If multiple functions are integrated into a single device, then device versatility is improved, but device complexity increases
Solution Approach 1:
The patent implements a function change key that can dynamically switch between different operational modes (first function and second function) based on the display state. When the display is extended, the key performs one function, and when retracted, it performs another function. This multi-functionality allows a single physical component to serve multiple purposes, increasing device versatility without proportionally increasing structural complexity
Solution Approach 2:
The system automatically adjusts the function of the key assembly based on the display configuration state. The processor detects whether the flexible display is in an extended or retracted state and automatically configures the key assembly to perform the appropriate function, eliminating the need for manual mode switching or complex user intervention to manage multiple functions
