Elongated Ruler Guide Plate for Ceramic Bottom Thickness Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of effective devices to precisely measure the thickness of a container's bottom, leading to inconsistent trimming of ceramic works, resulting in either excessive weight or potential rupture during kiln burning.
Innovation Solution
A device comprising an elongated guide plate mounted on a container's open top, with an elongated ruler inserted from the top and moved to contact both the interior and exterior surfaces, using guide portions to obtain indexes that calculate the thickness difference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If no measurement device is used, then the trimming process is simple and quick, but the thickness control is imprecise leading to weight or rupture issues
Solution Approach 1:
The patent uses the container's own rim as an intermediary reference point. The ruler is positioned against the rim, which serves as a natural datum, eliminating the need for external complex measurement equipment. This intermediary approach allows precise thickness measurement using simple tools already present in the pottery workspace.
2Manufacturing precision
If the bottom thickness is not precisely measured, then the trimming operation is faster, but the finished product may be too heavy or too thin causing rupture
Solution Approach 1:
The patent performs preliminary measurement of the bottom thickness before trimming. By measuring first with the ruler against the rim reference, the potter knows the exact thickness to remove, allowing quick and accurate trimming in one operation rather than repeated trial-and-error adjustments.
3Measurement precision
If a complex measurement device is designed, then measurement precision improves, but the device becomes difficult to operate and integrate into existing pottery processes
Solution Approach 1:
The measurement system uses the container's own rim as its reference standard, making the system self-contained and eliminating the need for external calibration equipment or complex setup procedures. The ruler combined with the rim creates a self-service measurement system that is immediately usable without additional training or equipment.

AI summary
A device for measuring container includes an elongated guide plate transversely mounted on an open top of a container. At least one elongated ruler is inserted into an interior of the container from the open top, and the end face of the distal end of the at least one elongated ruler contacts the inner end of the interior. The mediate section of the at least one elongated ruler contacts the elongated guide plate to obtain a first index. The at least one elongated ruler is moved to the exterior of the container and contacts a surface which is located on a common surface with the underside of the exterior of the container. The mediate section of the at least one elongated ruler contacts the elongated guide plate to obtain a second index. The difference between the first and second indexes is the thickness of the bottom of the container.
