Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional handheld laser machining apparatuses are cumbersome and difficult to handle due to their size and weight, leading to potential defects in machining and safety hazards if not properly stabilized during operation.
Innovation Solution
A handheld laser machining apparatus with a funnel that generates separate negative pressure regions to securely couple the apparatus to the workpiece, enhancing stability and ergonomics through a combination of suction and vacuum systems, and incorporating a scanner mounting and mirror deflecting system for precise beam control, allowing for improved handling and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the handheld apparatus is made larger and heavier to include all necessary components, then the functionality and power are improved, but the ease of operation and ergonomics deteriorate
Solution Approach 1:
The system is divided into two main segments: a handheld apparatus containing only the essential laser generation and control components, and a separate supply unit housing the power supply, fluid supply, and exhaust extraction systems. This segmentation allows the handheld portion to remain lightweight and easy to operate while the supply unit provides all necessary supporting functions.
Solution Approach 2:
A funnel is introduced as an intermediary component that couples the handheld apparatus to the workpiece. The funnel serves multiple functions: it directs exhaust gases away from the operator, provides a stable mounting surface for the handheld apparatus, and enables fluid supply to the workpiece area. This intermediary resolves the contradiction by allowing the handheld apparatus to remain simple while still achieving effective laser machining.
2Manufacturing precision
If the handheld apparatus is made more stable through increased weight, then the machining precision is improved, but the ease of operation and ergonomics worsen
Solution Approach 1:
The supply unit acts as a counterweight base that the handheld apparatus rests upon during operation. This external counterweight provides the necessary stability for precise machining without requiring the handheld apparatus itself to be heavy, thereby maintaining ease of operation while achieving manufacturing precision.
Solution Approach 2:
The funnel serves as an intermediary that provides a stable mounting interface between the handheld apparatus and the workpiece area. By coupling the handheld apparatus to the funnel, which is positioned on or near the workpiece, the system achieves stability for precise inscription without requiring the handheld apparatus to be inherently heavy or unwieldy.
3Ease of operation
If the handheld apparatus is moved away from the workpiece to improve ergonomics, then the handling comfort is improved, but the reliability of continuous machining deteriorates
Solution Approach 1:
The funnel acts as a permanent intermediary structure that remains positioned on the workpiece throughout the machining process. The handheld apparatus can be easily attached to and detached from the funnel, allowing the operator to maintain a comfortable position while ensuring the funnel continuously bridges the gap between the handheld apparatus and workpiece, thereby maintaining machining reliability.
Solution Approach 2:
The funnel is pre-positioned on the workpiece before the handheld apparatus is brought into operation. This preliminary action establishes a stable, fixed reference point that ensures the handheld apparatus can be quickly and easily coupled to the correct position, maintaining both ergonomic handling comfort and machining continuity without requiring the operator to manually position the handheld apparatus precisely during operation.

Function Achieved in This Case
The solution provides a stable and ergonomic handling experience, reducing the risk of machining defects and ensuring safe operation by maintaining a consistent connection between the apparatus and workpiece, while also enabling precise control over the laser beam.
Implementation Method 1
two different pumps are provided, by means of which two different negative pressure regions which are separate from one another can be generated at the funnel
