Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing measurement systems for folding machines require scanning both the underside of a sheet and the folding machine element, which reduces throughput due to the need to measure the scanner's angle with respect to the table, leading to inefficient use of scanning time.
Innovation Solution
A measurement system using a sensor arrangement and inclinometer to measure coordinates and inclination, allowing for the determination of the angle between two planes without directly measuring the element, thereby optimizing scanning efficiency and reducing processing time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a scanner is used to measure both the underside of a sheet and the element of the folding machine in several rotational positions, then the angle between the sheet and the element can be determined, but the throughput of the folding machine is reduced due to the time required to scan the element
Solution Approach 1:
The patent extracts the element scanning function from the measurement process. Instead of scanning both the sheet underside and the element, the system only scans the sheet underside while using an inclinometer to measure the element's angle independently. This separation eliminates the time-consuming element scanning step while maintaining measurement accuracy.
Solution Approach 2:
The inclinometer serves as an intermediary device that directly measures the angle between the element and the table without requiring the scanner to physically scan the element. This intermediary measurement approach bypasses the need for rotational scanning of the element, significantly reducing measurement time.
2Measurement precision
If the scanner rotates to multiple positions to measure distances to the sheet and element, then accurate angle determination is achieved, but the measurement time increases
Solution Approach 1:
The patent removes the unnecessary step of rotating the scanner to multiple positions to scan the element. The inclinometer directly provides the element's angle information, eliminating the time-consuming rotational scanning process while maintaining the ability to determine the folding angle accurately.
Solution Approach 2:
The patent replaces the mechanical rotational scanning system with an inclinometer that directly measures angles. Instead of using a rotating scanner to mechanically determine angles through multiple position measurements, the inclinometer provides direct angular measurement, significantly reducing measurement time.
