Validation Tool for Optical Equipment Tyre Component Overlap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The tyre building industry lacks a viable method to validate the accuracy and calibration of optical equipment used to measure the overlap length between leading and trailing ends of tyre components, as repeating measurements is impossible without destructive measures and each tyre component is unique.
Innovation Solution
A validation tool with reference elements representing the leading and trailing ends, offset to allow repeated measurements, enabling the verification of optical equipment accuracy and calibration by simulating the overlap conditions.

Engineering Contradiction Analysis
1Reliability
If measurements are repeated to validate optical equipment, then measurement consistency can be verified, but the tyre component must be destructively torn apart to re-expose the leading end
Solution Approach 1:
The patent creates a copy of the tyre component's measurement features by providing reference elements (first and second reference elements) that replicate the leading end and trailing end characteristics. These reference elements are offset to simulate the spliced condition while remaining permanently exposed for repeated non-destructive measurement, thus verifying measurement consistency without damaging the actual tyre component.
2Stability of the object's composition
If the trailing end and leading end are securely spliced together to form a tyre, then the tyre structure is complete, but the leading end cannot be re-exposed for repeated measurements
Solution Approach 1:
The patent introduces reference elements as intermediary objects that mediate between the need for structural integrity and repeated measurement capability. The first reference element represents the leading end and the second reference element represents the trailing end, both being permanently exposed and offset from each other. These intermediaries allow the optical equipment to repeatedly measure simulated splice conditions without requiring actual destruction of the spliced tyre structure.
3Measurement precision
If each tyre component is measured individually before and after splicing, then component-specific measurements are obtained, but validation is impossible as each component is slightly different
Solution Approach 1:
The patent applies homogeneity by making the reference elements identical and permanently exposed, creating a uniform measurement target that eliminates variations between different tyre components. The first and second reference elements are consistently positioned and structured, allowing the optical equipment to perform repeated measurements under identical conditions, thereby achieving measurement repeatability that is independent of individual component variations.

AI summary
Provided is a validation tool and a method for validating optical equipment that is used for measuring a plurality of characteristics of one or more tyre components during winding application of said tyre components around a tyre building drum, wherein a first tyre component of the one or more tyre components includes a first characteristic of the plurality of characteristics which, after measuring, is overlapped by the same or another tyre component of the one or more tyre components including a second characteristic of the plurality of characteristics, wherein the validation tool is provided with a first reference element that is arranged to represent the first characteristic and a second reference element that is arranged to represent the second characteristic, wherein the second reference element is offset with respect to the first reference element to at least partially expose the first reference element.
