Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a flexible display screen is folded without a sloping surface structure, then the device can be bent or folded, but the display screen cannot be divided evenly and the thickness is not uniform
Solution Approach 1:
The body is divided into three separate bodies (first body, second body, third body) that can be sequentially connected. Each body supports a portion of the flexible display screen, allowing the screen to be divided into three corresponding screens that fold evenly when the bodies are connected through bending portions.
Solution Approach 2:
A sloping surface is provided on the cross-section of the first and third bodies, creating an asymmetric structure. This sloping surface ensures that when the bodies are connected, the flexible display screen is divided evenly with uniform thickness, preventing the screen from being damaged during folding.
2Reliability
If magnetic coupling is used to attach bodies, then the attachment is secure and reversible, but the device structure becomes more complex
Solution Approach 1:
The patent replaces traditional mechanical attachment methods (such as screws, clips, or adhesives) with magnetic coupling. Magnets are embedded in the bodies to provide secure yet reversible attachment, allowing the bodies to be easily connected and disconnected without complex mechanical fastening mechanisms.
3Adaptability or versatility
If the flexible display screen is made thinner to achieve flexibility, then the device can be folded like paper, but the screen structure becomes more vulnerable to damage
Solution Approach 1:
The flexible display screen is divided into three separate screens corresponding to the three bodies. This segmentation allows each screen to be optimized for its specific function and position, reducing the risk of damage to the entire screen during folding operations.
Solution Approach 2:
The patent employs a flexible plastic substrate for the display screen that can be bent or folded into a desired shape. The substrate is designed with appropriate flexibility and thickness to withstand repeated folding while maintaining display quality and preventing damage.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution allows for even division and continuous operation of flexible display screens when folded, maintaining uniform thickness and enabling various usage scenarios by controlling power distribution and magnetic attachment, enhancing usability and versatility.
Implementation Method 1
The second body may comprise a predetermined magnetic region, and the sloping surface of the first body may be magnetically coupled and attached to a predetermined region of the second body.
