Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing measuring assemblies with dielectric windows, such as those made of glass or ceramic, are prone to partial failures that can result in undetectable splinters, posing a risk of unnoticed damage.
Innovation Solution
Incorporating a ferromagnetic marker, such as ferromagnetic marking particles or a coating, into the dielectric window to release detectable fragments upon failure, combined with a detector to identify these fragments using a sensitive magnetic detection system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dielectric window is used in a measuring assembly, then the window provides good electrical insulation and transparency, but partial failures can result in undetectable splinters
Solution Approach 1:
The patent applies the principle of visual/magnetic marking by incorporating ferromagnetic particles into the dielectric window material. These particles create a detectable magnetic signature that changes or becomes visible when the window fails, allowing partial failures to be detected through magnetic field interaction rather than visual inspection alone.
Solution Approach 2:
The ferromagnetic particles act as an intermediary between the dielectric window and the detection system. When the window fails and produces splinters, these particles serve as a mediator that carries the failure information to the detector, enabling indirect detection of the partial failure through magnetic field interaction.
2Reliability
If ferromagnetic marking particles are added to the dielectric window, then partial failures become detectable, but the marking particles may interfere with the dielectric material properties
Solution Approach 1:
The patent applies parameter changes by carefully controlling the concentration and size distribution of ferromagnetic particles within the dielectric window. By optimizing these parameters, the patent achieves sufficient detectability while minimizing interference with the dielectric material's electrical and mechanical properties.
Solution Approach 2:
The patent creates a composite material by combining dielectric material with ferromagnetic particles. This composite structure allows the window to maintain its primary dielectric function while incorporating the ferromagnetic marking capability, achieving both electrical insulation and failure detectability through a unified material system.
3Measurement precision
If a high concentration of marking particles is used, then detectability is improved, but the marking particles cause more interference with the dielectric material
Solution Approach 1:
The patent applies parameter changes by optimizing the concentration range of ferromagnetic particles. By maintaining the concentration within a specific range, the patent achieves adequate detectability sensitivity while preventing excessive interference with the dielectric material's uniformity and electrical properties.
