Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a dual-sided display device is designed with a slim profile, then the thickness is reduced, but the structural rigidity deteriorates
Solution Approach 1:
The frame is constructed using composite materials, specifically a metal base layer combined with a polymer coating layer. This composite structure provides both the slim profile required and the structural rigidity needed, as the metal layer offers strength while the polymer layer adds stiffness and protects against deformation
Solution Approach 2:
The frame incorporates local reinforcement through strategically positioned support ribs and thicker sections at critical stress points. This allows the overall frame to remain slim while providing enhanced rigidity where needed to support the dual display panels without excessive thickness
2Length of moving object
If a dual-sided display device is designed with a slim profile, then the thickness is reduced, but the image display quality deteriorates
Solution Approach 1:
The patent positions the light sources in the third dimension, placing LED backlight units behind each display panel within the slim frame structure. This spatial arrangement allows sufficient light emission path length for image quality while maintaining a thin overall profile by utilizing the depth dimension efficiently
Solution Approach 2:
The frame incorporates localized light guiding structures and reflective surfaces positioned close to each display panel. These local optical features enhance light distribution and intensity for each individual display surface, ensuring high image quality despite the limited thickness available for light sources
3Stability of the object's composition
If magnetic coupling and adhesive members are used to support dual display panels, then the structural integrity is improved, but the device complexity increases
Solution Approach 1:
The magnetic coupling mechanism and adhesive members are integrated into a unified attachment system within the frame structure. The magnets are embedded in specific pockets or channels that also accommodate adhesive application, combining two fastening functions into a single structural feature that simplifies assembly while maintaining structural integrity
