Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a laser source with adjustable beam radius is used to strip parts of varying diameters, then the versatility of the stripping tool is improved, but the difficulty of correctly positioning the laser with respect to the zone to be stripped increases
Solution Approach 1:
A camera is introduced as an intermediary device between the operator and the laser positioning task. The camera captures real-time images of the work area and displays them on a screen with an overlay pattern, serving as a mediator that simplifies the complex task of positioning the laser beam precisely on the zone to be stripped.
Solution Approach 2:
The system implements visual feedback by continuously displaying the camera image with an overlay pattern on the screen. This feedback loop allows the operator to see the laser position relative to the workpiece in real-time and make adjustments accordingly, making the positioning process intuitive and precise.
2Device complexity
If traditional brushes or counterbores are used for stripping, then the simplicity of the tool is maintained, but the need for multiple tools for different diameters increases device complexity
Solution Approach 1:
The laser stripping system is designed as a universal tool that can handle parts of various diameters through motorized adjustment of the laser beam radius. This single multi-functional device replaces the need for multiple specialized brushes or counterbores, each designed for a specific diameter range.
Solution Approach 2:
The laser beam radius is made dynamically adjustable through motorized control, allowing the system to adapt to different part diameters on-demand. This dynamic adjustment capability enables a single tool to perform the function of multiple fixed-dimension tools.
3Manufacturing precision
If manual positioning methods are used, then the simplicity of operation is maintained, but the manufacturing precision of the stripping operation deteriorates
Solution Approach 1:
The camera and screen overlay system acts as an intermediary that enhances positioning accuracy without complicating the operator's task. The visual guidance provided by the overlay pattern on the screen makes precise positioning as simple as aligning visual markers, combining high precision with ease of operation.

Data Source
AI summary
A method and a system for stripping a part which includes visualizing a zone to be stripped on a screen using a camera, aligning a center of the zone to be stripped with a pattern overlaid on the screen, defining a stripping dimension around the center of the zone to be stripped and controlling a laser source to have the laser source strip the zone to be stripped within that dimension. Such a method makes it possible to correctly visualize the positioning of the laser source with respect to the zone to be stripped before the stripping operation.
