Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Small Angle X-ray Scattering (SAXS) cameras face limitations in achieving high flux and resolution simultaneously, with one-dimensional cameras offering high throughput but limited to isotropic samples, and two-dimensional cameras providing anisotropic sample analysis but with lower flux and resolution compared to one-dimensional cameras.
Innovation Solution
A dual-mode SAXS camera system that includes a source, optic, and anti-parasitic scattering blocks, capable of producing both one-dimensional and two-dimensional beams, with a beam selection mechanism to switch between modes, utilizing a Kirkpatrick-Baez optic configuration and adjustable anti-parasitic scattering blocks to optimize flux and resolution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a one-dimensional beam is used in SAXS camera, then high flux and resolution are achieved, but the system is limited to isotropic samples only
Solution Approach 1:
The patent implements a dynamic beam selection mechanism that allows the SAXS camera to switch between one-dimensional and two-dimensional beam modes. This enables the system to adapt its beam configuration based on the sample type being analyzed, thereby resolving the contradiction between achieving high flux with 1D beams and the ability to analyze both isotropic and anisotropic samples.
Solution Approach 2:
The patent creates a universal SAXS camera system that can perform both one-dimensional and two-dimensional scattering measurements using a single instrument. By incorporating dual beam paths and a selection mechanism, the system achieves multi-functionality, allowing it to handle both isotropic and anisotropic samples while maintaining high flux performance.
2Adaptability or versatility
If a two-dimensional beam is used in SAXS camera, then anisotropic sample analysis capability is provided, but flux and resolution decrease compared to one-dimensional cameras
Solution Approach 1:
The system dynamically selects between 1D and 2D beam modes based on the analytical requirements. When high flux is needed for isotropic samples, the 1D mode is selected; when anisotropic sample analysis is required, the 2D mode is activated. This dynamic adaptation allows the system to maintain optimal flux performance for each specific application.
Solution Approach 2:
The patent segments the beam path into separate 1D and 2D beam lines, each optimized for specific measurement types. By providing distinct optical paths for 1D and 2D beams with independent optimization, the system can deliver high flux in 1D mode while also providing capable 2D mode when needed, rather than compromising one for the other.
3Device complexity
If a single SAXS camera system is designed, then device complexity is reduced, but it cannot simultaneously provide both one-dimensional and two-dimensional capabilities
Solution Approach 1:
The patent merges 1D and 2D beam capabilities into a single SAXS camera system by integrating dual optical paths and a unified detection system. The beam selection mechanism allows switching between modes without requiring separate instruments, thereby maintaining relatively simple device architecture while achieving versatile functionality.
Solution Approach 2:
The system achieves multi-functionality within a single camera platform by incorporating both 1D and 2D beam generation capabilities. The shared optical components and detection system are designed to handle both beam types, reducing the need for multiple separate systems while providing comprehensive analytical capabilities.
