Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional RGB LED color mixing is used, then the device structure is simple, but the number of color mixing regions is limited to seven
Solution Approach 1:
The patent divides the single color mixing region into multiple segmented regions by introducing a beam steering mechanism that can independently control different spatial zones. The light beam is segmented into multiple paths that create distinct color mixing regions (up to 51 regions) while maintaining the simplicity of the LED light source itself.
Solution Approach 2:
The patent transitions from a two-dimensional color mixing pattern (single plane overlap) to a three-dimensional spatial distribution by using beam steering to create color mixing regions at different positions and orientations. This dimensional expansion allows multiple color mixing regions to be formed without adding multiple LED sources.
2Adaptability or versatility
If the number of color mixing regions is increased to 51, then the lighting versatility is improved, but the device complexity increases
Solution Approach 1:
The patent employs a dynamic beam steering mechanism (such as a rotating prism or MEMS mirror) that can rapidly change the direction and position of light beams. This dynamic control allows the system to create up to 51 different color mixing regions on demand, providing high lighting versatility without requiring 51 separate static light sources or complex optical assemblies.
Solution Approach 2:
The beam steering mechanism serves multiple functions simultaneously: it divides the light beam into multiple paths, creates multiple color mixing regions, enables spatial control of color distribution, and allows dynamic reconfiguration of the lighting pattern. This multi-functionality achieves high versatility while minimizing the addition of separate device components.
3Ease of operation
If beam steering mechanism is added, then the color pattern can be steered to desired position, but the device complexity increases
Solution Approach 1:
The patent replaces complex mechanical beam steering systems with optically-based solutions such as rotating Fresnel prisms or acousto-optic modulators. These substitutions maintain the ability to steer color patterns to desired positions while reducing mechanical complexity, improving reliability, and enabling faster response times for color pattern control.

AI summary
A color mixing light system comprises a pyramidal mirror assembly comprising three or more mirrors constructed and arranged in a pyramid structure and three or more color light sources. The pyramidal mirror assembly divides the light beams from the color light sources so that a first portion is reflected by the mirrors and a second portion extends beyond the mirrors to collectively form a multicolor pattern comprising plurality of overlapping color regions on a surface.
