Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of car paint surfaces with varying surface normals and curvatures leads to inefficiencies in capturing specular reflection light, requiring multiple cameras and decreasing inspection device efficiency.
Innovation Solution
A car body inspection system comprising a main inspection device with an illuminator and a light receiver for inspecting a first area, coupled with an auxiliary inspection device to inspect a second area, where the light receiver does not receive specular reflection light, allowing for increased efficiency by distributing inspection tasks between devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple cameras are used to capture specular reflection light from the entire paint surface, then the inspection coverage is improved, but the device complexity and inspection efficiency deteriorate
Solution Approach 1:
The inspection system divides the car body surface into multiple inspection areas, with the main inspection device handling the first inspection area and auxiliary inspection devices handling the second inspection area. This segmentation allows each device to focus on specific areas where specular reflection light can be effectively captured, rather than requiring multiple cameras to cover the entire surface uniformly.
Solution Approach 2:
The patent applies different inspection approaches to different areas of the car body surface. The main inspection device uses specular reflection light capture for areas where this method is effective, while auxiliary inspection devices handle areas where specular reflection light cannot be received. This local differentiation optimizes the inspection approach for each specific area's characteristics.
2Area of stationary object
If multiple cameras are used to capture specular reflection light from the entire paint surface, then the inspection coverage is improved, but the inspection efficiency deteriorates
Solution Approach 1:
The inspection system divides the car body surface into multiple inspection areas, with the main inspection device handling the first inspection area and auxiliary inspection devices handling the second inspection area. This segmentation allows each device to focus on specific areas where specular reflection light can be effectively captured, rather than requiring multiple cameras to cover the entire surface uniformly.
Solution Approach 2:
The system automatically determines which areas can be inspected by the main inspection device using specular reflection light and which areas require auxiliary inspection devices. The controller automatically assigns inspection tasks based on the surface characteristics and light reception capabilities, eliminating the need for manual configuration and optimizing inspection efficiency.
3Area of stationary object
If the main inspection device attempts to inspect all areas, then the inspection coverage is improved, but the measurement precision deteriorates in areas without specular reflection light
Solution Approach 1:
The patent applies different inspection approaches to different areas of the car body surface. The main inspection device uses specular reflection light capture for areas where this method is effective, while auxiliary inspection devices handle areas where specular reflection light cannot be received. This local differentiation optimizes the inspection approach for each specific area's characteristics.
Solution Approach 2:
The controller acts as an intermediary that coordinates between the main inspection device and auxiliary inspection devices. It determines which areas can be inspected by the main device and assigns appropriate areas to auxiliary devices, ensuring that each area is inspected by the most suitable device for maintaining measurement precision.
