Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing processing systems face challenges in precisely controlling the relative positional relationship between the irradiation apparatus and the object being processed, leading to inefficiencies in processing light-based methods for modifying surface coatings, such as paint layers, without affecting the underlying object.
Innovation Solution
A processing system that uses a light irradiation apparatus with a driving system to adjust the position of the processing light relative to the object's surface, allowing for precise control of the target irradiation areas and energy distribution to selectively remove or modify the paint layer without exposing the underlying object, utilizing a combination of light sources and optical systems for focused and controlled processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the processing light energy is increased to effectively remove the paint layer, then the paint removal efficiency is improved, but the risk of damaging the underlying object increases
Solution Approach 1:
The patent applies local quality by concentrating the processing light energy precisely on the paint layer through focused optical systems, creating a localized high-energy zone that selectively removes paint while leaving the underlying object unaffected. The energy distribution is spatially differentiated to match the thickness profile of the paint layer.
Solution Approach 2:
The patent utilizes parameter changes by dynamically adjusting the energy parameters of the processing light (intensity, duration, wavelength) based on the detected paint layer thickness. The control system modifies these parameters in real-time to optimize paint removal while preventing damage to the substrate.
2Device complexity
If the processing system uses a fixed irradiation position, then the system structure is simplified, but the ability to handle objects of different sizes and shapes is reduced
Solution Approach 1:
The patent implements dynamics by introducing a movable irradiation apparatus that can dynamically adjust its position and orientation relative to the object being processed. This dynamic positioning system allows the fixed-structure light source to treat variable-geometry objects effectively.
Solution Approach 2:
The patent achieves universality by designing the irradiation apparatus with multi-functional capabilities - it can move to different positions, adjust its orientation, and modify its energy parameters to handle various object types, sizes, and shapes with a single device configuration.
3Productivity
If the processing light is applied uniformly across the surface, then the processing speed is improved, but the precision in controlling the depth of modification is reduced
Solution Approach 1:
The patent applies local quality by creating non-uniform energy distribution across the irradiated surface, with energy intensity specifically tailored to match the local paint layer thickness. This allows simultaneous high-speed processing with precise depth control through spatially varying energy parameters.
Solution Approach 2:
The patent implements feedback by using detection apparatus to measure the paint layer thickness and providing this information to the control system, which then adjusts the processing light energy distribution in real-time to achieve the desired modification depth while maintaining high processing speed.
