Radiographic Device Enclosure Impact Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional x-ray detectors are prone to mechanical failure due to their heavy and thick construction, which makes them vulnerable to impact and accidental drops, especially in portable designs that require both protection and lightweight functionality.
Innovation Solution
A cost-efficient, impact-resistant enclosure for x-ray detectors is created using a sheet metal unibody with relief cutouts and universal corner members, reducing the number of components and manufacturing complexity, while providing enhanced protection through a single-piece construction and angled design that absorbs impact forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional multi-piece metallic enclosures are used to protect the imaging panel, then mechanical protection is improved, but the detector becomes heavier and more prone to mechanical failure upon impact
Solution Approach 1:
The patent merges multiple separate enclosure pieces into a single-piece molded enclosure. The enclosure is formed as one integral component with integrated features such as recesses for corner protection and mounting structures, eliminating the need for multiple separate metal pieces, fasteners, and seams. This reduces weight while maintaining protective function.
Solution Approach 2:
The patent employs a molded material (such as polymer or composite plastic) that provides sufficient mechanical strength and impact resistance to protect the imaging panel. This material replaces traditional multi-piece metallic construction, achieving protection with reduced weight and without requiring assembly fasteners.
2Strength
If conventional multi-piece metallic enclosures with seams and screw fasteners are used, then structural support is improved, but the device complexity increases and manufacturing becomes more difficult
Solution Approach 1:
The patent combines multiple structural elements into a single molded piece. The enclosure includes integrated corner recesses, mounting flanges, and protective features all formed as one component. This eliminates seams, fasteners, and assembly steps, reducing complexity while maintaining structural integrity.
Solution Approach 2:
The enclosure incorporates segmented protective features such as recesses at corners and integrated mounting structures that are molded as part of the single piece. These segmented features provide structural support and protection without requiring separate components or assembly operations.
3Reliability
If thick and heavy panel support and external enclosure are used to protect sensitive imaging components, then reliability is improved, but the detector becomes less suitable for portable applications
Solution Approach 1:
The patent integrates the panel support and external enclosure into a unified single-piece structure. The molded enclosure provides both structural support and external protection simultaneously, eliminating the need for separate thick support structures. This maintains reliability while reducing overall weight and thickness for portability.
