Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a flexible display is positioned on the front surface of the mobile terminal, then the functionality and display area are improved, but the bezel area becomes difficult to reduce and structural complexity increases
Solution Approach 1:
The display unit is segmented into multiple functional components: cover glass, glass support with opening, frame with extensions, and flexible display. Each component has a specific function and can be manufactured independently, then assembled together. This segmentation allows for reduced bezel area while maintaining structural integrity and ease of manufacturing.
Solution Approach 2:
The flexible display is positioned within the housing, nested between the frame and the cover glass. The frame extensions are bent and nested within the housing structure, with the flexible display edge area disposed between the glass support and frame extensions. This nesting arrangement maximizes space utilization and reduces the overall bezel area.
2Area of moving object
If the bezel area is reduced to accommodate flexible displays, then the display area is improved, but the ease of manufacture and mounting deteriorates
Solution Approach 1:
The frame extensions are pre-bent into their final configuration before assembly. The glass support includes a pre-formed opening that will receive the frame protrusion. These preliminary actions simplify the final assembly process, making it easier to mount the flexible display while maintaining reduced bezel area.
Solution Approach 2:
The frame extensions act as intermediaries between the housing and the flexible display. They provide a mounting interface that simplifies the attachment process. The glass support with its opening serves as an intermediary structure that facilitates the connection between the frame and the housing, making the overall assembly easier to manufacture and mount.
3Strength
If frame extensions are bent and positioned between glass support and housing, then the structural integrity is improved, but the device complexity increases
Solution Approach 1:
The frame extensions are merged with the frame body to form an integrated structure. The extensions are bent from the frame body itself, creating a continuous structural element that provides both support and connection functions. This merging reduces the number of separate components while maintaining structural integrity.
Solution Approach 2:
The frame extensions utilize flexible bending capabilities to achieve their final positioned configuration. The extensions can be bent into the required shape during manufacturing or assembly, then maintain their positioned form to provide structural support. This flexibility allows for simplified manufacturing while maintaining structural integrity.
