Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional collimator designs with walls arranged in one direction or grid formation are used, then the structure is simple and easy to manufacture, but the ability to block scattered X-rays is insufficient
Solution Approach 1:
The collimator is divided into multiple modules, each containing a grid formation with walls arranged in intersecting directions. Each module can be independently manufactured and then assembled together, maintaining manufacturing simplicity while achieving superior scattered X-ray blocking when modules are combined in an array configuration
Solution Approach 2:
The patent transitions from traditional single-direction or simple grid wall arrangements to a multi-dimensional grid formation where walls are arranged in intersecting directions (first direction and second direction) within each module. This dimensional enhancement creates more blocking pathways for scattered X-rays without proportionally increasing overall structural complexity
2Object-affected harmful factors
If multiple modules are connected to form a grid structure, then scattered X-ray blocking is improved, but manufacturing and assembly complexity increases
Solution Approach 1:
The collimator system is segmented into multiple identical or similar modules, each with standardized grid formations. This segmentation allows for simplified manufacturing of individual modules using standard production techniques, and the modular design enables straightforward assembly by connecting pre-fabricated units, thereby maintaining ease of manufacture while achieving superior blocking performance through the combined array structure
3Measurement precision
If walls are arranged in intersecting directions in multiple modules, then radiation filtering accuracy is improved, but device complexity increases
Solution Approach 1:
The complex multi-directional wall arrangement is segmented across multiple modules rather than attempting to create a single monolithic structure. Each module contains a manageable grid formation with walls in intersecting directions, and the collective array of modules achieves the desired radiation filtering accuracy. This segmentation prevents excessive device complexity by distributing the geometric complexity across standardized modular units
Solution Approach 2:
Each module is designed with specific local wall arrangements optimized for blocking scattered X-rays from particular directions. The grid formation in each module has walls arranged in a first direction and a second direction to address local radiation filtering needs. When modules are assembled in an array, these local optimizations collectively provide comprehensive directional filtering, improving overall radiation detection accuracy without requiring every part of the entire collimator to be uniquely complex
