Segmented Shoulder Probe for Curved Edge Height Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need to quickly and accurately determine the height of edge portions of products, such as display glass sheets, with curved surfaces to ensure proper alignment and prevent damage, while existing methods struggle with interference and accuracy in measuring curved edges.
Innovation Solution
The solution involves an apparatus with a base, a probe, and a clamping pin, where the probe can move along a probe axis intersecting a determination axis, and the clamping pin is supported by a spring-loaded arm, allowing the probe to pass through an opening defined by the support arm to contact the edge portion without interference, enabling precise height determination with clearance between shoulder segments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a solid shoulder is used to define the determination axis for alignment, then alignment accuracy is improved, but the probe tip cannot contact the edge portion due to interference with the shoulder
Solution Approach 1:
The solid shoulder is divided into multiple shoulder segments spaced apart from one another. These segments collectively define the determination axis for alignment while creating gaps that allow the probe tip to access and contact the edge portion without interference from the shoulder structure.
2Productivity
If the probe is positioned close to the edge portion for high-density measurements, then measurement density is improved, but the probe interferes with the shoulder structure
Solution Approach 1:
The shoulder is segmented into multiple spaced-apart segments that create channels or gaps between them. These gaps provide clearance for the probe to move close to the edge portion for high-density measurements while preventing interference with the shoulder structure.
3Measurement precision
If multiple measurements are taken at different locations along the edge portion, then measurement accuracy is improved, but measurement time increases
Solution Approach 1:
The shoulder segments are pre-positioned to define the determination axis and provide alignment features before measurement begins. The product is pre-aligned using these segments, enabling rapid sequential measurements at multiple locations without time-consuming realignment between measurements.

AI summary
Apparatus can comprise a probe movable in a direction along a probe axis that intersects a determination axis and a clamping pin can be movable along a clamping pin axis that intersects a product support area of a base. In some embodiments, methods of determining a height of an edge portion of a product can comprise aligning the edge portion of the product along a determination axis and clamping the product to a base at a clamping location of the product positioned over a product support area. Methods can further comprise extending a probe to contact a location of the edge portion of the product while the product is clamped to the base. Methods can further comprise determining a height of the edge portion of the product based on the position of the probe contacting the edge portion of the product.
