X-ray Cassette Support Structure for Impact Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing X-ray cassettes with flat panel detectors are prone to damage due to impact during transport, as the detecting medium is not adequately protected from lateral forces, leading to potential collisions with walls or other objects.
Innovation Solution
The cassette design includes a support structure with a larger base material that extends beyond the image receiving unit, providing a buffer against impacts and distributing the force of collisions, thereby reducing direct contact and damage to the detector.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cassette is formed as a thin panel for portability, then ease of operation is improved, but impact resistance deteriorates
Solution Approach 1:
The patent applies beforehand cushioning by providing a buffer material between the case and the detecting medium. This buffer material is positioned in advance to absorb and reduce the strength of impacts that may occur during transport, protecting the detecting medium from damage while maintaining the thin panel design for portability
2Strength
If buffer material is provided between case and detecting medium, then impact resistance is improved, but device complexity increases
Solution Approach 1:
The patent employs a buffer material that functions as a flexible protective layer between the case and detecting medium. This flexible buffer provides impact protection without requiring complex structural modifications, maintaining simplicity while enhancing durability during transport
3Strength
If the support extends beyond the substrate outer edge, then impact resistance is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent applies local quality by extending the support structure specifically at the peripheral regions beyond the substrate outer edge, where impact forces are most likely to occur. This localized reinforcement provides enhanced impact resistance at critical areas without requiring high-precision alignment across the entire structure, thereby reducing manufacturing precision requirements
