Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible display panel is made foldable to improve adaptability, then the device can be carried in various configurations, but the display panel becomes vulnerable to deformation and damage from external impacts
Solution Approach 1:
The patent introduces an impact absorbing member positioned between the display panel and the support unit to cushion external impacts before they reach the display panel. This preemptive protective measure absorbs impact energy and reduces the risk of deformation and damage to the foldable display panel, thereby maintaining reliability while preserving foldability.
Solution Approach 2:
The impact absorbing member serves as an intermediary element between the support unit and the display panel. It mediates the interaction by absorbing and dissipating impact forces, preventing direct transmission of harmful forces to the display panel. This intermediary structure enables the display panel to maintain its foldable configuration without compromising integrity.
2Stability of the object's composition
If adhesive members are used to couple the impact absorbing member and support unit, then structural stability is improved, but the complexity of assembly increases
Solution Approach 1:
The adhesive members are designed to self-align and self-couple the impact absorbing member to the support unit. The protrusions on the impact absorbing member fit into corresponding receiving portions on the support unit, with adhesive members automatically positioning themselves during assembly. This self-service mechanism simplifies the assembly process while ensuring stable coupling.
Solution Approach 2:
The protrusions on the impact absorbing member are received within receiving portions on the support unit, creating a nested configuration. This nesting arrangement provides structural stability while keeping the assembly compact and manageable, reducing the complexity of putting the components together.
3Stability of the object's composition
If protrusions and receiving portions are added to control lateral movement, then the display panel's position is stabilized, but the device complexity increases
Solution Approach 1:
The coupling interface is segmented into discrete protrusions on the impact absorbing member and corresponding receiving portions on the support unit. This segmentation allows for controlled lateral movement while maintaining overall stability. Each protrusion-receiving portion pair acts as an independent constraint point, providing position stability without requiring a complex monolithic structure.

AI summary
An electronic apparatus includes a display panel including a folding portion overlapping with a folding axis, a first non-folding portion and a second non-folding portion, a support unit including a first support portion arranged under the first non-folding portion and a second support portion arranged under the second non-folding portion, an impact absorbing member interposed between the display panel and the support unit and coupled to the display panel, an adhesive member coupling the impact absorbing member to the support unit, a receiving portion defined in at least one of the first support portion or the second support portion, and a protrusion connected to the impact absorbing member and received in the receiving portion. A planar area of the protrusion is less than a planar area of the receiving portion.
