Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial CT scanning faces challenges with vibration, movement, and shifting of larger or heavier components during cone beam scanning, leading to blurry and unusable images, as existing ad-hoc measures like excessive taping or preprogrammed stoppages are insufficient and inefficient.
Innovation Solution
An anti-vibration fixture comprising a radiolucent enclosure with a vibration-dampening material attached to its inside face and a plurality of fasteners on opposing faces, securely holding components and reducing vibrations by actuating the fasteners to a predetermined torque, thereby stabilizing components during CT scanning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If ad-hoc measures like excessive taping or preprogrammed stoppages are used to prevent vibration, then component stability is improved, but scanning efficiency and productivity deteriorate
Solution Approach 1:
The fixture divides the component support function into separate modular elements: vibration-dampening material for stability, fasteners for securement, and radiolucent enclosure for containment. This segmentation allows each element to perform its specific function efficiently without interfering with the scanning process, resolving the contradiction between stability and productivity
Solution Approach 2:
The fixture is pre-configured with vibration-dampening material and fasteners before the component is placed. This preliminary preparation ensures that when scanning begins, the component is already secured and stabilized, eliminating the need for stoppages or adjustments during scanning, thus maintaining high productivity while ensuring stability
2Ease of operation
If conventional fixing methods are used for larger or heavier components, then ease of operation is maintained, but image quality and measurement precision deteriorate due to vibration and movement
Solution Approach 1:
The vibration-dampening material serves as an intermediary between the component and the fixture enclosure. It absorbs vibrations and movements that would otherwise affect image quality, while still allowing the component to be easily placed and secured using simple fasteners, thus maintaining ease of operation while improving measurement precision
3Reliability
If radiolucent materials are used for the enclosure, then CT scanning capability is improved, but structural strength and vibration resistance deteriorate
Solution Approach 1:
The fixture uses a composite structure combining radiolucent enclosure material with separate vibration-dampening material. The radiolucent material maintains CT scanning capability while the dampening material provides the necessary vibration resistance, resolving the contradiction between scanning capability and structural strength
