Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the reflector rotates to reflect light from each side in succession, then scanning capability is achieved, but aerodynamic drag and thermal friction increase
Solution Approach 1:
The patent applies curvature to the intersections of the reflector surfaces, creating rounded transitions instead of sharp corners. This curved geometry allows air to flow more smoothly over the rotating reflector, reducing aerodynamic drag and thermal friction while maintaining the rotational scanning function
2Adaptability or versatility
If the reflector rotates to reflect light from each side in succession, then scanning capability is achieved, but light scattering increases
Solution Approach 1:
The curved intersections guide light more predictably across the reflector surfaces, reducing unintended scattering and improving beam quality during rotation
Solution Approach 2:
The patent applies different surface properties to different regions of the reflector, with specific attention to the intersection areas. The curved intersections are designed to minimize light scattering while maintaining the overall reflective function needed for scanning
3Device complexity
If the reflector has sharp intersections between surfaces, then structural simplicity is maintained, but aerodynamic drag increases
Solution Approach 1:
The patent introduces curvature at the intersections without significantly complicating the overall reflector structure. The curved intersections provide aerodynamic benefits by smoothing airflow while maintaining the basic polyhedral geometry and manufacturing simplicity

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design enhances aerodynamic performance and reduces light scattering, resulting in improved scanning accuracy and the ability to place scanners in closer proximity without interference.
Implementation Method 1
a reflector that together generate a scanning beam... light from the light emitting component is reflected from each side of the reflector
Implementation Method 2
A portion of each intersection may include a flat, curved, and/or otherwise aerodynamically formed portion that reduces aerodynamic drag when the reflector is in operation and spinning
Implementation Method 3
light scattering, or rather, scattered light in portions of the beam from light reflected off of intersections between surfaces of the reflector

AI summary
An improved prismatic polygonal reflector with increased aerodynamic properties and reduced scattering of reflected light is provided. The reflector may be used for scanning, and may include a first end, a second end, a plurality of side surfaces located circumferentially about a center axis of the reflector, and a plurality of intersections joining the plurality of side surfaces. Each of the plurality of intersections includes a curved or a flat portion and a pointed portion aligned circumferentially with other pointed portions on the plurality of intersections to provide a circumference around the reflector for light to reflect and form a scanning beam without light scattering. A system and method for scanning with the reflector is also provided.
