Solution Overview

Problem

Existing optical measurement systems face challenges in efficiently redirecting light signals for enhanced scanning and resolution, particularly in areas with varying collision risks, while maintaining structural simplicity and mobility.

Innovation Solution

The implementation of a redirection region with curvature allows for the redirection body to be moved relative to the light signal propagation axis, changing the point of incidence and angle of incidence, enabling flexible scanning and adjustable resolution through curvature design.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a flat redirection region is used, then the structure is simple, but the scanning flexibility and resolution are limited

Engineering Contradiction:
Improvescanning flexibilityVSAvoidredirection region structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies curvature to the redirection region surface, transforming it from a flat plane to a curved surface. This curvature enables the redirection body to redirect light signals to different angles by moving along the curved surface, thereby achieving scanning flexibility without requiring complex mechanical pivot mechanisms. The curved surface allows variable angles of incidence as the redirection body moves, enabling flexible monitoring region scanning.

Inventive Principle:
Principle #14Spheroidality (Curvature)

2Adaptability or versatility

If the redirection body is moved to change the point of incidence, then scanning flexibility improves, but adjustment complexity increases

Engineering Contradiction:
Improvescanning capabilityVSAvoidadjustment effort
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The curved redirection region is designed to work passively with the movement mechanism. As the redirection body moves along the curved surface, the geometry of the curve automatically provides the desired angular variation for scanning. The system leverages the inherent geometric properties of the curved surface to achieve scanning functionality without requiring complex active adjustment mechanisms, thereby reducing adjustment effort while maintaining scanning flexibility.

Inventive Principle:
Principle #25Self-service

3Measurement precision

If a curved redirection region is used, then resolution can be enhanced in specific areas, but manufacturing complexity increases

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The curved redirection region can be designed with varying curvature radii in different areas. By adjusting the curvature radius locally, the patent enables higher resolution in specific regions (such as areas with higher collision risk) while maintaining simpler geometry in other regions. This local variation of geometric properties allows optimization of measurement precision in critical areas without uniformly increasing manufacturing complexity across the entire redirection region.

Inventive Principle:
Principle #3Local quality
