Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If beam splitting is used to generate five beams from a single laser source, then the device complexity is reduced, but the beam intensity is reduced leading to less bright projection points
Solution Approach 1:
The patent segments the laser beam generation by using three separate laser sources instead of splitting one beam. Each laser source generates one or more beams independently, avoiding the intensity loss associated with beam splitting while still achieving the five-beam configuration through spatial arrangement and selective switching of the sources.
2Illumination intensity
If one laser source per beam is used to maintain beam intensity, then projection point brightness is improved, but the device complexity and space requirements increase
Solution Approach 1:
The patent merges multiple laser sources into a compact arrangement where three laser sources generate five beams through strategic positioning and beam splitting of two sources. The optical elements and laser sources are integrated in a space-saving configuration that maintains high brightness while avoiding excessive device complexity.
Solution Approach 2:
The patent introduces dynamic switching capability among the three laser sources, allowing selective activation of individual sources or combinations thereof. This dynamic control enables flexible beam configuration and maintains brightness by activating only the necessary sources for each measurement task, reducing effective device complexity during operation.
3Quantity of substance
If beam splitting is used to create five beams, then the quantity of beams is increased, but the beam intensity is reduced
Solution Approach 1:
Instead of splitting a single beam into five weaker beams, the patent segments the laser source configuration into three independent sources that collectively produce five beams. Two sources each generate two beams through splitting, while the third source generates one beam, maintaining higher intensity per beam compared to uniform splitting of a single source.
