Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If overhead projectors are used to display images on ramps, then visual information can be provided to users, but the images become distorted and out of focus due to varying ramp contours
Solution Approach 1:
The patent uses LED video substrates that directly display images on the ramp surface, creating a faithful copy of the intended visual content without the optical distortion problems of projection systems. The LED substrates are conformally mounted to match the ramp contours, ensuring accurate image reproduction.
Solution Approach 2:
The patent changes the display technology from projection-based optical systems to direct LED emission, fundamentally altering how images are created and displayed on the ramp surface. This parameter change eliminates the distortion issues inherent in projection systems while maintaining visual information delivery.
2Area of stationary object
If projectors are used to display images on ramps, then visual content can be shown, but the projection area is limited and images are smaller than the actual ramp surface area
Solution Approach 1:
The patent divides the display system into modular LED video substrate segments that can be independently mounted on different portions of the ramp. This segmentation allows the display to cover the entire ramp surface area while maintaining consistent image quality across all segments through individual calibration.
Solution Approach 2:
The LED video substrate system serves multiple functions: it provides full-surface coverage, maintains consistent image quality, and can be adapted to various ramp geometries. The universal mounting structure allows the same technology to be applied across different ramp sizes and shapes.
3Ease of manufacture
If standardized radii and surface materials are used in ramp construction, then manufacturing is simplified, but the display system cannot adapt to varying ramp contours
Solution Approach 1:
The patent employs dynamic mounting structures that can adapt to different ramp contours while maintaining standardized construction benefits. The LED video substrates are mounted using flexible support systems that conform to varying geometries, allowing the same standardized ramp construction to accommodate diverse display requirements.
