Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flat panel displays distort spherical data, such as maps, due to the inherent inability to accurately project a spherical surface onto a flat surface, leading to varying degrees of deformation and inaccuracy.
Innovation Solution
A deformation controllable display method and apparatus that acquires target shape information of a spherical surface display object and adjusts the display area to match the corresponding shape, minimizing distortion by deforming the display to match the shape of the spherical surface object, using mechanisms like pneumatic structures or flexible displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a flat panel display is used to display spherical surface objects, then the display structure is simple and fixed, but the displayed content suffers from distortion and deformation
Solution Approach 1:
The patent applies the dynamics principle by transforming the display surface from a static flat panel to a dynamic deformable surface. The display apparatus can change its shape between flat and spherical configurations, allowing it to adapt to different display requirements. This resolves the contradiction by enabling high display accuracy for spherical content when deformed, while maintaining simplicity when flat.
Solution Approach 2:
The patent implements parameter changes by modifying the physical shape parameter of the display surface. By changing the curvature parameter from zero (flat) to a spherical value, the display can accurately represent spherical surface objects. This parameter transformation allows the display to maintain both structural simplicity and high manufacturing precision depending on the operational state.
2Adaptability or versatility
If a globe is used to display spherical surface objects, then distortion is minimized, but the display size is fixed and cannot present different scales
Solution Approach 1:
The patent applies dynamics by creating a display that can dynamically adjust its size and shape. The deformable display can expand or contract while maintaining its spherical configuration, allowing it to present different scales of spherical surface objects. This resolves the contradiction between fixed globe size and scalable display requirements while preserving geometric accuracy.
Solution Approach 2:
The patent implements universality by designing a display apparatus that can serve multiple functions: displaying spherical content with minimal distortion, adjusting to different scales, and potentially transitioning between flat and spherical states. This multi-functional design allows a single device to replace both traditional flat displays and fixed globes, achieving both adaptability and precision.
3Manufacturing precision
If mathematical projection methods are used to convert spherical content to flat display, then the display structure remains simple, but errors and deformation are introduced
Solution Approach 1:
The patent directly applies the spheroidality principle by using a physically spherical or deformable display surface instead of relying on mathematical projection to spherical coordinates. This eliminates projection errors entirely by matching the physical geometry of the display surface to the geometry of the content being displayed, achieving high manufacturing precision without complex projection calculations.
