Radiation Window Protective Device for X-Ray Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
X-ray device windows are fragile and prone to damage from foreign objects or samples, leading to costly replacements and downtime, as thin windows are necessary for low-energy X-ray transmission but vulnerable to contact.
Innovation Solution
A protective device with radiation path openings is designed to surround the window, allowing X-ray transmission while preventing external forces from damaging it, maintaining the sample's proximity to the detector and allowing for easy replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If thin windows are used to allow transmission of low energy X-rays, then X-ray transmission capability is improved, but window strength and resistance to damage deteriorates
Solution Approach 1:
A protective device is introduced as an intermediary component between the external environment and the thin radiation window. This protective device has openings that allow radiation to pass through while providing mechanical protection to the window, preventing direct contact with foreign objects or samples.
Solution Approach 2:
The protective device is designed with multiple openings rather than a solid structure, segmenting the protective function into discrete radiation-transmissive regions. This allows the protective device to maintain structural integrity and protection capability while permitting radiation transmission through the segmented openings.
2Use of energy by moving object
If thin windows are used to allow transmission of low energy X-rays, then X-ray transmission capability is improved, but susceptibility to damage by foreign objects or samples increases
Solution Approach 1:
The protective device serves as a mediator that blocks harmful mechanical contact while allowing beneficial radiation transmission. It is positioned between potential damaging objects (foreign objects or samples) and the thin window, preventing direct interaction that could cause damage.
Solution Approach 2:
The protective device provides preemptive protection by being in place before any potential damage can occur. It creates a protective barrier that absorbs or deflects external forces before they can reach the vulnerable thin window, cushioning it against potential impacts.
3Reliability
If protective measures are added to protect the window, then window protection is improved, but device complexity increases
Solution Approach 1:
The protective function is extracted as a separate, removable device rather than being integrated into the main chamber structure. This allows the protective device to be independently designed, installed, and replaced without modifying the core X-ray device, thereby minimizing the increase in overall device complexity.
Solution Approach 2:
The protective device is designed to be adaptable and potentially reusable across different configurations or applications. By creating a universal protective component that can be applied to protect radiation windows in various settings, the complexity increase is amortized across multiple uses rather than requiring custom solutions for each case.
4Reliability
If protective measures are added to protect the window, then window protection is improved, but manufacturing cost increases
Solution Approach 1:
The protective device is designed as a simpler, potentially disposable or easily replaceable component compared to the expensive radiation window it protects. By using less expensive materials and simpler construction for the protective device, the overall cost increase is minimized while still achieving the protection function.
