Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roll alignment measurement technologies are limited by the need for high-resolution sensors and complex setups, making it difficult for non-experts to accurately measure and correct roll alignment in roll process lines, and they struggle to determine the relative distance and orientation of rolls, leading to inefficiencies and product defects.
Innovation Solution
An apparatus with a subject position fix unit and a relative position measurement unit that uses laser signals to measure roll alignment, including a first, second, and third laser receiver, and a detection result output unit to provide real-time alignment data, allowing for quick and accurate alignment of rolls regardless of distance or sensor resolution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high-resolution sensors are used to measure roll alignment, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent replaces complex mechanical alignment measurement systems with an optical laser-based system. The laser beam serves as a reference line, and the position of the laser spot on the measurement roll surface is detected to determine alignment, eliminating the need for complex mechanical gauges and high-resolution contact sensors.
Solution Approach 2:
The patent introduces a laser beam as an intermediary reference element between the measurement system and the roll. The laser beam creates a visible reference line that simplifies the measurement process, allowing alignment to be determined by observing where the laser spot falls on the roll surface rather than using direct complex measurement apparatus.
2Measurement precision
If complex measurement setups are used to determine roll alignment, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
The patent uses the visible laser beam and laser spot as a visual indicator for alignment measurement. The laser spot's position on the roll surface provides an intuitive visual reference that operators can easily interpret, eliminating the need for complex gauge readings or sophisticated measurement procedures.
Solution Approach 2:
The patent replaces complex mechanical measurement procedures with a simple optical visualization method. Operators only need to observe the laser spot position on the roll surface to determine alignment, making the process as simple as reading a visual indicator rather than operating complex measurement equipment.
3Measurement precision
If traditional measurement methods are used to determine roll distance and orientation, then compatibility with existing systems is maintained, but measurement precision deteriorates
Solution Approach 1:
The patent creates a universal measurement system based on laser optics that can measure both distance and orientation parameters simultaneously. The same laser beam and detection mechanism provide comprehensive alignment information, replacing multiple specialized measurement tools while maintaining compatibility with the measurement roll structure.
Solution Approach 2:
The patent replaces traditional mechanical measurement tools with an optical system that provides superior precision for both distance and orientation measurements. The laser-based system eliminates cumulative errors from mechanical linkages while maintaining adaptability to the roll structure through non-contact measurement.
