Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pyrometer mounting assemblies require complete disassembly for cleaning viewport windows, compromising accuracy and repeatability of temperature measurements due to the need for frequent cleaning before and during crystal growth processes.
Innovation Solution
An adjustable pyrometer mount with a removable viewport mechanism, featuring a window containment arm that can be pivoted in and out of a cavity, allowing for maintenance without disassembling the pyrometer, ensuring accurate and repeatable temperature measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pyrometer mounting assembly is completely disassembled for cleaning viewport windows, then the windows can be accessed and cleaned, but the accuracy and repeatability of pyrometer readings are compromised
Solution Approach 1:
The mounting assembly is divided into separate components: the pyrometer holder remains fixed while the viewport window is made independently removable. This segmentation allows the window to be accessed and cleaned without disturbing the pyrometer's position and alignment, thus maintaining measurement precision while improving ease of operation.
Solution Approach 2:
The viewport window is extracted as a separate removable component from the mounting assembly. This allows the window to be removed, cleaned, and reinstalled without requiring disassembly of the pyrometer holder or affecting the pyrometer's alignment, thereby resolving the contradiction between accessibility for cleaning and measurement accuracy.
2Ease of operation
If the pyrometer mounting assembly is completely disassembled for cleaning viewport windows, then the windows can be cleaned, but the time required for disassembly and reassembly increases furnace downtime
Solution Approach 1:
By segmenting the mounting assembly so that only the viewport window is removable while the pyrometer holder remains fixed, the cleaning operation is simplified to involve only the window component. This reduces the time required for cleaning operations and minimizes furnace downtime while maintaining full accessibility to the windows.
Solution Approach 2:
The viewport window is extracted as a separate removable component, allowing it to be quickly removed, cleaned, and reinstalled without involving the pyrometer or other mounting components. This extraction approach significantly reduces the time required for cleaning operations and minimizes disruption to furnace operations.
3Ease of operation
If the pyrometer mounting assembly is completely disassembled for cleaning viewport windows, then the windows can be cleaned, but the complexity of the mounting assembly increases
Solution Approach 1:
The mounting assembly is segmented into simple, distinct components: a fixed pyrometer holder and a removable viewport window. This segmentation provides easy accessibility for cleaning while keeping each component simple in design, avoiding the need for complex disassembly mechanisms and thus not increasing overall assembly complexity.
Solution Approach 2:
The viewport window is extracted as a separate removable component with a simple mounting mechanism. This extraction approach simplifies the overall assembly by allowing the window to be independently accessed and maintained without complex integration with the pyrometer holder, thereby improving ease of operation without significantly increasing device complexity.

AI summary
According to the disclosed embodiments, an illustrative apparatus that is configured to attach to a viewport of a container comprises a first plate having a first aperture and an attached second plate having a second aperture substantially aligned to the first aperture. The first and second plates, when attached, define a cavity from an outer edge of the first and second plates to the substantially aligned apertures. A window containment arm is pivotally affixed to at least the first plate and configured to substantially fit and pivot into and out of the cavity, and a window contained within the window containment arm is positioned such that the window substantially aligns with the first and second apertures when the window containment arm is fully pivoted into the cavity, and such that the window is accessibly located outside of the cavity when the window containment arm is pivoted out of the cavity.
