Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a flexible display is used in a foldable terminal, then a large display area is obtained in unfolded state and small volume in folded state, but the flexible display becomes vulnerable to damage due to impact from other structures during falls
Solution Approach 1:
The patent applies beforehand cushioning by introducing a stress buffer structure at the bent section and end portions of the screen decorating member before any impact occurs. This stress buffer structure is designed to absorb and dissipate impact forces when falls occur, preventing direct transmission of forces to the flexible display. The stress buffer structure includes stress relief grooves or notches that are pre-formed to accommodate impact forces, thereby protecting the flexible display in advance against potential damage during falls.
2Reliability
If a screen decorating member is added to protect the flexible display, then damage protection is improved, but the device complexity increases
Solution Approach 1:
The patent applies local quality by introducing the stress buffer structure only at specific critical locations (bent section and end portions) of the screen decorating member, rather than making the entire member complex. The stress buffer structure includes localized stress relief grooves or notches positioned precisely where impact forces are most likely to affect the flexible display. This localized approach provides effective protection while maintaining simplicity in the overall device structure, avoiding unnecessary complexity in areas where the stress buffer is not needed.
Solution Approach 2:
The patent applies segmentation by dividing the screen decorating member into distinct functional sections: a main body portion and stress buffer portions (bent section and end portions). The stress buffer structure is segmented into separate stress relief features (grooves or notches) that are integrated into specific segments of the member. This segmentation allows the screen decorating member to perform multiple functions (decoration, protection, stress relief) through modular design, improving protection without proportionally increasing overall complexity.
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
Reduces the frequency and intensity of impact sounds, maintains the appearance effect, and protects the flexible display from punctures or collisions during falls.
Implementation Method 1
The bent section and/or the second end portion are provided with a stress buffer structure. The stress buffer structure is disposed at the bent section and/or the second end portion to implement the protection of the screen body, to avoid a case that when the electronic device falls, the screen body and/or the screen decoration vibrates or displaces under the action of impact
Implementation Method 2
avoid a case that when the electronic device falls, the screen body and/or the screen decoration vibrates or displaces under the action of impact and the bent section and/or the second end portion of the screen decorating member cause/causes damage to the screen body
