OSEE Probe Segmentation for Tight Space Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current optically stimulated electron emission (OSEE) sensing apparatuses have limitations in using larger probe tips, which can result in inconsistent readings due to movement and require larger surface areas for stability, making them less suitable for tight spaces and applications requiring precise positioning.
Innovation Solution
The development of an OSEE apparatus with a smaller probe tip and a movable head portion that can align itself relative to the surface, utilizing a gimbal apparatus to maintain consistent contact and orientation, allowing for interchangeable probe tips and improved positioning in tight spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a larger probe tip is used for stability, then the device can maintain consistent readings, but it requires larger surface areas and cannot fit in tight spaces
Solution Approach 1:
The probe is divided into a stationary body portion and a movable head portion. The body portion can be smaller to fit tight spaces, while the head portion maintains the necessary size for stable readings. The head portion is movably coupled to the body portion, allowing it to be positioned and oriented independently to ensure consistent contact with the surface being inspected.
Solution Approach 2:
The head portion is designed to be movable relative to the body portion, enabling dynamic adjustment of the probe's contact point and orientation. This allows the probe to adapt to various surface geometries and maintain stable readings without requiring a uniformly large probe tip, thus reducing the overall size requirement while preserving reading consistency.
2Reliability
If a larger probe tip is used for stability, then the device can maintain consistent readings, but it cannot be used in tight spaces
Solution Approach 1:
The probe is divided into a stationary body portion and a movable head portion. The body portion can be smaller to fit tight spaces, while the head portion maintains the necessary size for stable readings. The head portion is movably coupled to the body portion, allowing it to be positioned and oriented independently to ensure consistent contact with the surface being inspected.
Solution Approach 2:
The movable head portion adds a degree of freedom in positioning, allowing the probe to access tight spaces from different angles. The head can be adjusted independently of the body, enabling the probe to reach confined areas while maintaining the necessary contact stability for reliable readings.
3Area of stationary object
If the probe tip is made smaller for tight spaces, then accessibility is improved, but positioning consistency becomes difficult to maintain
Solution Approach 1:
The probe is divided into a stationary body portion and a movable head portion. The body portion can be smaller to fit tight spaces, while the head portion maintains the necessary size for stable readings. The head portion is movably coupled to the body portion, allowing it to be positioned and oriented independently to ensure consistent contact with the surface being inspected.
Solution Approach 2:
The movable head portion can self-adjust to maintain optimal contact with the surface being inspected. This self-adjusting capability compensates for the smaller size of the probe, ensuring that positioning consistency is maintained even in tight spaces where manual alignment would be difficult.

The head portion is designed to be movable relative to the body portion, enabling dynamic adjustment of the probe's contact point and orientation. This allows the probe to adapt to various surface geometries and maintain stable readings without requiring a uniformly large probe tip, thus reducing the overall size requirement while preserving reading accuracy.

AI summary
An apparatus for inspecting a surface includes a housing and a probe. The housing includes a light source to direct light along a longitudinal axis and a shutter to selectively allow light to pass through to the probe. The probe includes a body portion and a head portion. The head portion of the probe includes a collector to detect photoelectrons emitted from the surface in response to light from the light source impinging on the surface. A proximal portion of the head portion moves relative to a distal portion of the head portion to allow for variations in angle relative to the surface.
