Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the support structure uses a uniform thick design to provide stable support for the flexible display panel, then the structural strength is improved, but the ease of rolling and unrolling deteriorates due to increased stress on the display panel
Solution Approach 1:
The support structure employs varying thickness across different regions: a first support region with greater thickness for enhanced structural strength, and a second support region with lesser thickness to reduce stress during rolling operations. This local differentiation allows the support to provide stable support where needed while facilitating easy rolling in other areas, directly resolving the contradiction between structural strength and ease of rolling.
2Ease of operation
If the support structure uses a thinner design to facilitate rolling and unrolling, then the ease of rolling is improved, but the structural strength deteriorates causing instability
Solution Approach 1:
The support structure employs varying thickness across different regions: a first support region with greater thickness for enhanced structural strength, and a second support region with lesser thickness to reduce stress during rolling operations. This local differentiation allows the support to provide stable support where needed while facilitating easy rolling in other areas, directly resolving the contradiction between structural strength and ease of rolling.
3Reliability
If the support structure uses a complex patterned design with multiple components to optimize stress distribution, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The support structure utilizes a flexible support layer with integrated patterns (such as grid patterns, circular patterns, or curved patterns) that provide stress distribution and structural reinforcement without requiring multiple separate components. This approach enhances reliability through the patterned design while avoiding the complexity of assembling multiple parts, as the patterns are formed directly in the flexible support layer material.

AI summary
Provided is a support, including a flexible support layer and a plurality of support strips. The flexible support layer has a first surface and a second surface opposite to each other. The second surface is configured to support a flexible display panel. The flexible support layer includes a slidable-rollable region and a planar support region adjacent to each other. The plurality of support strips are disposed on the first surface and in the slidable-rollable region, and the plurality of support strips are successively arranged along a first direction away from the planar support region. The first direction is parallel to the first surface and intersected with a lengthwise direction of the support strip.
