Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional substrate structures are used, then manufacturing is simpler, but substrate shifting and spacer misalignment occur reducing stability
Solution Approach 1:
The substrate structure is segmented into multiple functional regions including first and second substrate portions, protrusion structures, and spacer regions. This segmentation allows each region to perform its specific function while maintaining overall structural integrity and preventing shifting and misalignment.
Solution Approach 2:
The patent introduces a third dimension by creating protrusion structures that extend vertically from the substrate surface. This vertical dimension provides mechanical interlocking features that prevent substrate shifting and improve spacer positioning without adding complex lateral structures.
2Manufacturing precision
If spacers are positioned without protrusion structures, then manufacturing is easier, but spacer misalignment occurs
Solution Approach 1:
The protrusion structures are formed in advance during the substrate fabrication process, creating pre-positioned mechanical features that guide subsequent spacer placement. This preliminary action ensures precise spacer alignment without requiring complex real-time positioning mechanisms.
Solution Approach 2:
The protrusion structures serve as intermediary elements between the substrate and the spacers. These intermediate features provide mechanical reference points and positioning constraints that ensure precise spacer alignment while simplifying the overall manufacturing process.
3Stability of the object's composition
If substrate structures are made more stable, then display panel reliability improves, but structural complexity increases
Solution Approach 1:
The patent merges multiple stability-enhancing features into an integrated substrate structure. The protrusion structures, spacer regions, and substrate portions are combined into a single unified design that provides mechanical interlocking and prevents shifting without requiring separate stabilization components.
Solution Approach 2:
Different regions of the substrate are designed with local quality variations, where protrusion structures are positioned at specific locations to provide targeted mechanical support and alignment. This localized approach improves stability without uniformly increasing complexity across the entire substrate.

AI summary
An electronic device is provided. The electronic device includes a first substrate structure having a first overlapping region and two protrusion structures. The first overlapping region is located between the two protrusion structures. The electronic device includes a second substrate structure disposed opposite to the first substrate structure. The second substrate includes a first spacer overlapping the first overlapping region of the first substrate structure. The first substrate structure further includes a base, a scan line and two adjacent data lines. The scan line and the two adjacent data lines are disposed on the base, and the scan line between the two adjacent data lines has two wider portions and a narrower portion disposed between the two wider portions.
