Solution Overview
Problem
Conventional scan sensors require multiple installations to scan light along multiple planes, leading to increased labor and costs, particularly in crime prevention scenarios involving objects like shelves or bronze statues.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple scan sensors are installed to scan light along multiple planes, then the scanning coverage is improved, but the installation labor and costs increase
Solution Approach 1:
The patent applies multi-functionality by enabling a single scan sensor to perform multiple scanning functions across different planes. The optical system includes multiple reflective surfaces (first, second, and third reflective surfaces) that redirect the scanned light along three different planes (first, second, and third planes), allowing one sensor to replace what would traditionally require three separate sensors. This resolves the contradiction by maintaining comprehensive scanning coverage while reducing the number of sensors needed.
Solution Approach 2:
The patent transitions from two-dimensional scanning (single plane) to three-dimensional scanning (multiple planes) by introducing multiple reflective surfaces at different orientations. The optical system redirects light along three mutually orthogonal planes, adding spatial dimensions to the scanning capability. This allows a single sensor to achieve multi-plane coverage by utilizing dimensional redirection of light paths, resolving the contradiction between coverage area and device complexity.

Solution Approach 2:
The patent merges multiple scanning functions into a single integrated system. Instead of using separate sensors for each plane, the invention combines three scanning functions (along three different planes) into one sensor unit with an optical system that includes multiple reflective surfaces. This merging reduces the total quantity of sensors required, thereby reducing costs while maintaining comprehensive scanning coverage.
