Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current laser cleaning scanners have a fixed focal depth, limiting their flexibility and applicability, especially when cleaning objects with deep surfaces, as they require a specific distance between the laser exiting port and the surface.
Innovation Solution
An adjustable focus laser cleaning galvanometer is developed, featuring an adjustable lens set with movable lenses and a galvanometer that can swing, allowing for adjustable focal lengths and depths, enabling effective cleaning of objects with varying dimensions and depths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed focal length lens is used in the laser cleaning scanner, then the structure is simple and easy to manufacture, but the flexibility and scope of application are limited due to inability to clean deep surfaces
Solution Approach 1:
The patent applies the dynamics principle by making the lens set adjustable rather than fixed. The lens can move along the optical path to change the focal length dynamically, allowing the same device to adapt to different cleaning depths and surface types. This transforms a static optical system into a dynamic one that can be configured for various applications.
Solution Approach 2:
The patent implements parameter changes by allowing the focal length to be varied through lens positioning. By changing the optical parameters (focal length, focal depth) of the lens set, the system can effectively clean surfaces at different depths and configurations, thereby improving adaptability without fundamentally changing the device structure.
2Reliability
If a fixed focal depth is used, then the device structure is simplified, but the cleaning effectiveness on deep surfaces is reduced
Solution Approach 1:
The lens set is designed to be movable along the optical axis, enabling dynamic adjustment of focal depth. This allows the system to maintain reliable cleaning effectiveness on deep surfaces by positioning the lens at appropriate distances, while keeping the overall device structure relatively simple through a single degree of freedom adjustment mechanism.
Solution Approach 2:
The adjustable lens set provides multi-functionality by enabling the same laser cleaning device to effectively clean various surface types including deep grooves, complex geometries, and different material surfaces. This universal capability improves reliability across diverse applications without requiring multiple specialized devices.
