Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lights in process chambers of machines are not robust enough to withstand conditions such as chips and contaminants, and obstructive tool holders or shadows hinder visual observation of the process.
Innovation Solution
A compact, surface-mounted or built-in lamp with a panel-shaped light exit opening and a recess for a pivoting camera, surrounded by LED light sources, which allows for wide-area illumination and adjustable camera alignment to minimize shadows and contamination risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional lights are used in process chambers, then illumination is provided, but the lights are not robust enough to withstand conditions such as chips and contaminants
Solution Approach 1:
The patent applies a protective glass plate (dünne Glasplatte) that covers the light exit opening, forming a barrier that protects the light components from chips and contaminants while allowing light to pass through. This thin film/shell approach provides robustness without significantly affecting the illumination function.
2Productivity
If tool holders or workpiece holders are placed in the process chamber, then processing is enabled, but they obstruct the view or cast shadows
Solution Approach 1:
The patent positions the light source at the front wall of the process chamber, illuminating from a dimension perpendicular to the typical viewing angle. This spatial arrangement allows light to enter from the front while the camera observes from the side, enabling both processing tools and clear visualization without mutual obstruction.
Solution Approach 2:
The patent provides targeted illumination at the workpiece location through the front wall, creating localized lighting exactly where needed for both processing and observation. This localized quality of light ensures that the workpiece area is well-illuminated without requiring light sources that would obstruct the camera view.
3Volume of moving object
If a compact lamp structure is used, then space is saved, but the light may not cover a large area
Solution Approach 1:
The patent extracts the light source from a traditional enclosed lamp structure and positions it directly at the front wall with an open light exit. This extraction allows the compact lamp body to remain small while the light itself spreads over a large area of the process chamber, achieving both compactness and wide coverage.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides optimal visual observability of the process by reducing shadows and preventing contaminant settlement, ensuring clear and effective illumination and observation within the process chamber.
