Camera-Guided Paint Spraying Through Shielded Outdoor Painting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing painting technologies face challenges in preventing paint scattering during outdoor painting, especially due to wind, which causes damage to property and health, and poses safety risks to workers. Additionally, the use of shielding devices in painting devices makes it difficult for workers to monitor the painting process, including checking the paint distribution, quality, and movement path.
Innovation Solution
An electronic device equipped with a communication circuit, display, and processor is used to obtain images of the painting process through cameras integrated into the painting device. This device calculates depth information, generates depth images, and extracts curvature and paint quality information. It then displays this information to the user, allowing for better control of the painting process despite the presence of shielding devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a shielding device is added to the painting device to prevent paint scattering, then safety and environmental protection are improved, but the worker's ability to monitor the painting process and check paint distribution deteriorates
Solution Approach 1:
The patent introduces a camera system as an intermediary device that captures images of the painting process through the shielding device. This allows the worker to monitor paint distribution and quality without direct visual access, resolving the contradiction by mediating between the shielding function and monitoring requirement
Solution Approach 2:
The patent creates a visual copy (image) of the painting process by using a camera to capture and transmit real-time footage to a display device. This copy allows the worker to observe the painting state without removing the shielding device, thus maintaining both safety and monitoring capabilities
2Reliability
If a shielding device is added to the painting device to prevent paint scattering, then worker safety is improved, but the ability to check movement path and painting quality deteriorates
Solution Approach 1:
The camera system acts as an intermediary that transmits visual information about the painting process and movement path to the worker, compensating for the information loss caused by the shielding device while maintaining worker safety
Solution Approach 2:
The patent implements a feedback loop where the camera continuously captures images of the painting process, and the display device provides real-time visual feedback to the worker, enabling continuous monitoring of painting quality and movement path despite the shielding device
3Device complexity
If manual monitoring is used to check painting quality and movement path, then equipment complexity is reduced, but painting precision and quality control deteriorate
Solution Approach 1:
The patent replaces manual visual monitoring with an automated optical system (camera and display). This substitution maintains relatively simple equipment while significantly improving painting quality control by providing objective, real-time visual feedback on paint distribution and movement path
