Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If overhead projectors are used to project images onto the ramp, then images can be displayed on the ramp surface, but the images become distorted, out of focus, or out of proportion due to the varying contours of the ramp
Solution Approach 1:
The patent replaces the mechanical projection system (overhead projector) with a digital video system that uses LEDs embedded within the ramp structure itself. This substitution eliminates the fundamental problem of projection distortion by generating light directly at the display surface rather than projecting from a distance, allowing images to be displayed accurately conforming to the ramp's contours without suffering from focus issues or distortion.
Solution Approach 2:
The invention transitions from a two-dimensional projection onto a curved surface to a three-dimensional integrated display where LEDs are embedded within the ramp structure itself. This dimensional change allows the display elements to be positioned exactly where light is needed, conforming to the ramp's varying contours and eliminating the distance-related distortion problems inherent in projection systems.
2Illumination intensity
If projectors are used to compensate for sizing inconsistencies, then images can be displayed, but the projection area is limited and the resulting images are smaller than the actual ramp surface area
Solution Approach 1:
The patent makes the ramp structure itself multi-functional by integrating LED display capabilities directly into the ramp. The ramp serves both its original purpose as a physical structure and as a display surface, eliminating the need for separate projection equipment and maximizing the usable display area to match the full ramp surface area rather than being limited by projector constraints.
Solution Approach 2:
The invention replaces the external projection system with an integrated LED system embedded in the ramp structure. This substitution allows the display area to extend across the entire ramp surface without being constrained by the limited projection area of external projectors, as the LEDs are distributed throughout the ramp structure itself.
3Ease of manufacture
If standardized radii and surface materials are used in ramp construction, then manufacturing is simplified, but the ramp cannot accommodate dynamic or interactive video displays that adapt to contours
Solution Approach 1:
The patent merges the structural ramp construction with the video display system by embedding LEDs within the ramp structure itself. This combination allows the ramp to maintain its standardized construction for ease of manufacture while simultaneously gaining advanced interactive display capabilities that can adapt to the ramp's contours through the distributed LED arrangement and digital video control system.
Solution Approach 2:
The invention introduces dynamics to the previously static ramp structure by integrating a digital video system with embedded LEDs that can dynamically change displays, interact with users, and adapt to the ramp's contours. The standardized ramp construction provides a stable base that now supports dynamic, programmable video content, combining manufacturing simplicity with operational versatility.
