Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Scanning large and heavy components is challenging due to deflection of scanner members and limited sample size by cabinet designs, which interfere with scanning operations and require improved rigidity and access for heavy samples.
Innovation Solution
A scanning system with parallel rails, a movable gantry, and a sample platform that can move along multiple axes, combined with a shielded cabinet featuring overlapping doors for easy access and radiation shielding, ensuring stability and safety during scanning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the scanner supports and moves large and heavy components, then the scanning capability is improved, but deflection of scanner members occurs reducing precision
Solution Approach 1:
The scanner is divided into multiple independent support members (first support member, second support member, third support member) that can be individually positioned and adjusted. This segmentation allows each support member to bear specific portions of the heavy component's weight, distributing the load and reducing deflection of any single member while maintaining the ability to scan large components.
Solution Approach 2:
The support members are positioned at different locations along the component being scanned, creating a multi-dimensional support structure. This spatial distribution of support points in multiple dimensions allows the system to handle heavy components while maintaining scanning precision through reduced deflection at each support point.
2Object-affected harmful factors
If the cabinet is designed for radiation shielding, then operator protection is improved, but access for loading heavy samples is limited
Solution Approach 1:
The cabinet door is segmented into multiple sections or panels that can be independently opened or adjusted. This segmentation allows the door to provide full radiation shielding when closed while enabling easy access for loading and unloading heavy samples by opening only the necessary portions, rather than requiring the entire door to be removed or opened.
3Measurement precision
If the scanner is designed for high precision scanning, then measurement accuracy is improved, but handling of heavy components becomes difficult
Solution Approach 1:
The scanning system is segmented into multiple independent scanning units or detectors positioned at different locations. Each unit can independently scan portions of heavy components with high precision, and the data is integrated to provide complete coverage. This segmentation allows heavy components to be scanned accurately without requiring the entire scanner to be moved or repositioned as a single unit.
Solution Approach 2:
The scanning approach transitions from moving the entire scanner in one dimension to using multiple fixed scanning positions distributed in multiple dimensions. This allows heavy components to remain stationary while scanners at different spatial positions capture data from various angles and locations, maintaining high precision without the complexity of moving heavy equipment.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively scans heavy components up to 100 kg with reduced deflection, allowing for varied sample sizes and providing safe operator protection from radiation.
Implementation Method 1
A position of the sample platform can be adjusted by the gantry and the vertical track. The sample can be exposed to x-rays from an x-ray tube.
Implementation Method 2
The x-rays can be received by a detector opposite the x-ray tube. In such situations, the received x-rays have passed through the sample.
