Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If direct beam measurement is used to ensure measurement accuracy, then measurement precision is improved, but device volume increases due to long measurement path
Solution Approach 1:
The patent introduces a light impediment unit as an intermediary object between the beam source and detector. This unit creates a shadow area that indirectly reflects beam characteristics (divergence and directionality). By measuring the shadow area instead of the beam directly, the system achieves accurate measurement while significantly shortening the optical path length, thus reducing device volume while maintaining measurement precision.
2Adaptability or versatility
If integrated measurement of divergence angle and directionality is performed in the same device, then measurement completeness is improved, but device complexity increases
Solution Approach 1:
The patent designs the light impediment unit and detection unit as a universal measurement system that can simultaneously measure both divergence angle and directionality of the beam. By positioning the light impediment unit at specific locations and using appropriate detection algorithms, the same hardware configuration enables both measurement functions, thereby improving measurement completeness while avoiding the complexity of separate dedicated measurement devices.
