Sensor Tilting Mechanism for Offset Object Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sensors, such as 3D laser scanners and cameras, struggle to detect objects that are offset from the viewing window, resulting in incomplete capture and recognition of barcodes or other information.
Innovation Solution
The sensor's information capture unit is designed with a defined reference edge and can be tilted to position its diagonal with the maximum number of signal detection points parallel to the reference edge, allowing for a wider detection angle without altering the sensor's components or resolution, ensuring complete object detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the sensor housing is mounted with the viewing window edge aligned parallel to the system, then the sensor structure is simple and stable, but the detection area is limited and offset objects cannot be completely captured
Solution Approach 1:
The patent makes the information capture unit movable relative to the viewing window by implementing a tilting mechanism. The capture unit can be rotated between a first position (edges parallel) and a second position (diagonal parallel), transforming a static structure into a dynamic one that adapts to different detection requirements.
Solution Approach 2:
The patent introduces a rotational degree of freedom around the optical axis of the sensor. By rotating the information capture unit around this axis, the detection area orientation changes from being constrained to one dimension (parallel to housing edges) to being adjustable in multiple orientations, effectively utilizing angular dimensionality.
2Adaptability or versatility
If the information capture unit is fixed in the first position with edges parallel to the viewing window, then the sensor structure is simple, but the detection angle is limited and cannot detect offset objects completely
Solution Approach 1:
The patent implements a tilting mechanism that allows the information capture unit to rotate between a first position (edges parallel to viewing window) and a second position (diagonal parallel to viewing window). This dynamic adjustment enables the sensor to adapt to objects at different angular positions, increasing the detection angle from a fixed orientation to multiple orientations.
Solution Approach 2:
The patent makes the information capture unit multi-functional by enabling it to operate in at least two distinct positions. In the first position, it captures objects aligned with the housing edges; in the second position, it captures objects aligned with diagonal directions. This multi-position capability provides universal detection coverage for various object orientations without requiring multiple separate sensors.
3Area of stationary object
If the viewing window size is increased to capture more offset objects, then the detection coverage is improved, but the sensor housing size and complexity increase
Solution Approach 1:
Instead of increasing the physical size of the viewing window or housing, the patent employs a dynamic tilting mechanism for the information capture unit. By rotating the capture unit between different angular positions, the effective detection coverage is expanded without requiring a larger housing. The same capture surface area is reused at different orientations, achieving increased coverage efficiency.
Solution Approach 2:
The patent changes the orientation parameter of the information capture unit rather than changing the size parameter of the housing or viewing window. By adjusting the angular parameter (tilting the capture unit between parallel and diagonal orientations), the detection coverage is optimized for different object positions without increasing the physical dimensions of the sensor housing.
