Solution Overview
Problem
The area monitoring system disclosed in Patent Literature 1 is limited by the light path constraint between the monitoring apparatus and the reflector, which restricts its functionality.
Innovation Solution
A sensor apparatus incorporating a laser ranging device that scans a predetermined range with laser light and uses reflection mirrors to redirect at least part of the laser light through a detection region from a non-parallel direction, allowing for diverse light paths and improved detection capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the laser light path is limited to a line connecting the monitoring apparatus and the reflector, then the system structure is simple, but the functionality is limited
Solution Approach 1:
The patent introduces a reflection mirror to change the light path from a one-dimensional line connecting monitoring apparatus and reflector to a two-dimensional configuration. The mirror redirects laser light at angles not parallel to the incident direction, enabling the light to pass through the detection region and expand the functional capabilities of the system.
Solution Approach 2:
The reflection mirror acts as an intermediary element that facilitates the interaction between the laser light and the detection region. By positioning the mirror to reflect light through the detection region, it enables new detection capabilities without directly modifying the monitoring apparatus or reflector.
2Measurement precision
If the light path is constrained to a direct line between monitoring apparatus and reflector, then the system is easy to implement, but detection accuracy is reduced due to light blockage
Solution Approach 1:
By introducing the reflection mirror, the system transitions from a single-line light path to a multi-directional light path configuration. This allows laser light to reach the detection region from different angles, reducing the likelihood of blockage and improving detection accuracy.
Solution Approach 2:
The reflection mirror is pre-positioned to redirect laser light through the detection region before the light reaches the reflector. This preliminary redirection ensures that the detection region is properly illuminated from optimal angles, enhancing detection capability.
