Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for measuring the cross-section of long profiles, especially at elevated temperatures, are inefficient and imprecise due to the need for complex mechanical support structures, which are cumbersome and costly, and often rely on inaccurate methods using wooden boards.
Innovation Solution
A method and device utilizing a light section sensor mounted on a pivoting device that moves in a ring-shaped path around the long profile, allowing for precise measurement without complex support structures, using multiple laser beams and automatic or semi-automatic image capture from various angles to reconstruct the cross-section, with optional wireless data transmission and portable design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If complex mechanical support structures are used to position sensors precisely, then measurement precision is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent replaces complex mechanical support structures with a light section measurement system that uses optical fields (laser beams) to define measurement planes. The sensor position is determined by the optical measurement geometry rather than mechanical positioning, eliminating the need for precise mechanical alignment and complex support structures.
Solution Approach 2:
The system changes from requiring precise mechanical position parameters to using optical field parameters (laser beam geometry, measurement plane orientation). By transforming the measurement approach from mechanical positioning to optical field definition, the system achieves high precision without complex mechanical structures.
2Measurement precision
If complex mechanical support structures are used, then measurement precision is improved, but ease of operation and assembly deteriorate
Solution Approach 1:
The patent eliminates complex mechanical support structures by using a light section measurement system where the measurement plane is defined by optical fields rather than mechanical fixtures. This substitution dramatically simplifies assembly and operation while maintaining high measurement precision.
3Device complexity
If wooden boards are used instead of support structures to save costs, then device complexity is reduced, but measurement precision deteriorates
Solution Approach 1:
The patent replaces simple but imprecise mechanical supports (wooden boards) with an optical measurement system using light sections and laser beams. This substitution maintains structural simplicity while dramatically improving measurement precision by using optical field geometry instead of mechanical contact.
Solution Approach 2:
The system creates an optical copy of the measurement plane using laser beams and light sections, eliminating the need for physical mechanical supports. This optical copying approach provides both simplicity and high precision simultaneously.
4Measurement precision
If a fixed geometry measuring frame is used for hot profiles, then measurement precision is improved, but adaptability and ease of manufacture deteriorate
Solution Approach 1:
The patent transitions from a fixed geometry measuring frame to a dynamic light section measurement system. The measurement plane can be dynamically adjusted and repositioned using optical fields, allowing adaptation to various profile shapes and positions without requiring physical reconfiguration of rigid structures.
Solution Approach 2:
The light section measurement system serves multiple functions: it can measure different profile shapes, adjust to various positions, and adapt to hot profiles without requiring different physical fixtures. The optical measurement plane provides universal adaptability across different measurement scenarios.
