X-ray detector force distribution layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing X-ray detector enclosures are prone to damage from applied stresses and shocks due to their rigid structure, which can lead to deflection, cracking, or deformation, and current shock mounts are inadequate in distributing forces effectively, complicating the internal structure and not providing significant protection for internal components.
Innovation Solution
Incorporating a lightweight, rigid foam force distribution layer with a honeycomb or lattice structure within the enclosure to distribute loads and absorb shocks, eliminating the need for separate shock mountings and allowing for thinner enclosure materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid enclosure structure is used to provide structural integrity and protection, then strength and protection are improved, but the enclosure becomes susceptible to deflection, cracking, or deformation under stress and shock
Solution Approach 1:
The patent employs a composite structure combining a rigid enclosure shell with a compliant foam filler material. The rigid enclosure provides structural integrity and protection, while the foam filler (made of materials like polyethylene, polypropylene, or polyurethane) absorbs shock and stress through deformation. This composite approach allows the system to maintain strength while reliably withstanding external forces without cracking or deforming.
2Reliability
If shock mounts are added to protect internal components, then protection is improved, but device complexity increases and space is consumed
Solution Approach 1:
The patent merges the shock absorption function into the existing enclosure structure by filling the internal void space with foam material. Instead of adding separate shock mount components, the foam serves both as structural filler and shock-absorbing element. This integration protects internal components from shock while maintaining a simple, clean internal structure without additional mounting hardware.
Solution Approach 2:
The foam filler material performs multiple functions simultaneously: it fills empty space within the enclosure, provides shock absorption, protects internal components from impact, and potentially provides thermal insulation. This multi-functionality eliminates the need for separate shock mounting components, reducing overall device complexity while maintaining comprehensive protection.
3Strength
If thicker enclosure materials are used to prevent damage, then strength is improved, but weight increases
Solution Approach 1:
The patent uses a composite design where a thin rigid enclosure shell is combined with a foam filler material. The rigid shell provides structural integrity and damage resistance, while the foam filler absorbs impact energy. This allows the enclosure to withstand shocks and stresses without requiring excessive thickness, thereby maintaining lightweight construction while achieving adequate protection.
Solution Approach 2:
The patent changes the material parameters by introducing a foam filler with different mechanical properties than solid metal or plastic enclosures. The foam's compressibility and energy absorption characteristics allow the system to achieve equivalent or superior shock resistance with thinner overall construction, reducing weight while maintaining strength and protection capabilities.

AI summary
An x-ray detector 14 for obtaining x-ray images of an object is provided that is capable of increasing the ability of the detector to withstand shock and other types of forces acting on the enclosure 122 to prevent and/or limit damage to the internal components of the detector 14. The enclosure 122 includes an internal filler/force distribution layer 124 formed from a lightweight, rigid material such as rigid foam and/or a suitable structure, such as a honeycomb or other lattice structure. The material is formed or shaped to fill a layer or portion of the interior of the detector 14 that is otherwise empty space defined between the various internal components of the detector. The position and shape of the force distribution layer 124 determines the path of load distribution across or through the enclosure away from the internal components of the detector and is optimized for shock absorption and/or load distribution.
