Adjustable-Width Underbody Inspection Robot for Multi-Angle Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional car underbody inspection robots face limitations in capturing smooth images due to restricted camera angles, especially when inspecting cars with low heights, and lack the ability to accurately inspect tire treads and collect sound data, hindering efficient online and non-face-to-face transactions.
Innovation Solution
A car underbody inspection robot with adjustable width, equipped with multiple cameras and a tread inspection camera, capable of taking overlapping images and sound data collection, controlled by a unit that generates a single matching image and evaluates performance using a management server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If cameras are installed on the left and right sides of the upper surface of the main body to photograph the underbody, then the robot can capture images of the car underbody, but the imaging is not smooth due to limited angles, especially for low-height cars
Solution Approach 1:
The robot employs multiple cameras mounted on movable arms that can dynamically adjust their positions and angles. The cameras are not fixed but can be extended and repositioned to capture images from optimal angles, allowing the system to adapt to different car heights and underbody configurations, thereby resolving the contradiction between imaging quality and adaptability.
Solution Approach 2:
The patent introduces vertical dimensionality by mounting cameras on extendable arms that can move up and down, rather than fixing them only on the horizontal upper surface. This multi-dimensional positioning capability allows the cameras to capture images from various heights and angles, improving both imaging quality and adaptability to different car types.
2Adaptability or versatility
If the robot is designed with fixed width, then the structure is simple, but it cannot inspect various types of cars with different widths
Solution Approach 1:
The robot body is divided into modular segments including a main body and multiple expandable units that can be connected in series. This segmentation allows the robot to adjust its overall width by adding or removing units, enabling it to fit under different car types while keeping each individual module relatively simple in structure.
Solution Approach 2:
The robot features expandable and contractible structural units that can dynamically adjust the width of the robot body. These units can be extended to increase width for larger vehicles or contracted for narrower spaces, providing adaptability without requiring completely different robot designs for each car type.
3Productivity
If the robot performs automated inspection, then labor efficiency is improved, but the system requires complex coordination of multiple cameras and data processing
Solution Approach 1:
The patent integrates multiple camera functions and data processing capabilities into a unified control system. The control unit coordinates all cameras, processes images from multiple sources, and generates comprehensive inspection reports automatically, simplifying the overall system architecture while maintaining high inspection efficiency through automated operations.
