Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiography systems face challenges in aligning radiation source units and panel units, particularly when these units can travel individually, making precise alignment difficult.
Innovation Solution
A radiography system comprising a radiation source unit and a panel unit, both equipped with detection units (optical cameras) and traveling mechanisms, where the control device uses detection results to adjust the relative position and posture of the units, facilitated by common-shaped base portions with markers for alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the radiation source unit and panel unit can travel individually, then mobility and flexibility are improved, but alignment precision deteriorates
Solution Approach 1:
The patent introduces detection units (cameras) and markers as intermediary elements to facilitate alignment between the radiation source unit and panel unit. The detection units capture images of markers on the opposite unit, and the control device processes these images to calculate position and posture deviations, enabling precise alignment despite individual mobility of the units
Solution Approach 2:
The patent replaces mechanical alignment mechanisms with an optical detection and control system. Instead of using mechanical guides or physical contact methods to ensure alignment, the system uses cameras to detect marker positions, processes image data computationally, and controls the units' positions and postures through software-based feedback
2Manufacturing precision
If detection units and control systems are added to enable alignment, then alignment precision is improved, but device complexity increases
Solution Approach 1:
The detection units and control system serve multiple functions: they not only enable alignment between the radiation source unit and panel unit, but also provide position monitoring, posture control, and verification of proper facing orientation. This multi-functionality justifies the added complexity by consolidating multiple operational needs into a single integrated system
