Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If an optomechanical member is used to scan light, then the field of view can be covered, but the scan becomes nonlinear causing non-uniform illumination
Solution Approach 1:
A lens is introduced as an intermediary optical element between the optomechanical member and the field of view. This lens receives the nonlinearly scanned primary light and transforms it into linearly scanned secondary light, achieving uniform illumination without modifying the optomechanical member itself
Solution Approach 2:
The lens changes the propagation parameters of the light by linearizing the scan trajectory. The lens optically transforms the nonlinear scan of primary light into a linear scan of secondary light, converting the illumination pattern from non-uniform to uniform across the field of view
2Productivity
If a nonlinear scan is used to cover the field of view, then the scanning speed can be increased, but the data transfer efficiency decreases
Solution Approach 1:
The lens acts as an intermediary that decouples the scanning speed from the data transfer efficiency. It allows the optomechanical member to scan at higher speeds using nonlinear trajectories while the lens transforms this into efficient linear scanning patterns for optimal data acquisition
3Illumination intensity
If the optomechanical member directly produces linear scan, then uniform illumination is achieved, but the mechanical complexity increases
Solution Approach 1:
Rather than making the optomechanical member mechanically complex to achieve linear scanning, a lens is introduced as a simpler optical intermediary. The lens performs the linearization function optically, keeping the optomechanical member relatively simple while achieving uniform illumination
Solution Approach 2:
The patent replaces a potentially complex mechanical linear scanning system with an optical solution. Instead of mechanically forcing linear motion, the system uses a lens to optically transform nonlinear mechanical motion into linear light propagation

AI summary
An optical transformer includes: an optomechanical member configured: to receive incident light; and to produce primary light from the incident light including an initial propagation that includes a nonlinear scan; and a lens configured: to receive the primary light from the optomechanical member; to linearize the nonlinear scan; and to produce secondary light including a final propagation that comprises a linear scan, such that the optical transformer is configured to transform the nonlinear scan of the primary light to the linear scan of the secondary light. A process for optically transforming a nonlinear scan includes receiving an incident light by an optical transformer that includes an optomechanical member and a lens; producing a primary light from the incident light that includes an initial propagation having a nonlinear scan; communicating the primary light from to the lens; and producing a secondary light to optically transform the nonlinear scan, the secondary light including a final propagation that comprises a linear scan, based on optically linearizing the initial propagation.
