Solution Overview
Problem
Existing medical X-ray photography apparatuses for dental panoramic photography require complex operations and can result in incorrect positioning, leading to suboptimal image quality and increased burden on patients, especially in intraoral radiography where precise alignment is crucial.
Innovation Solution
A medical X-ray photography apparatus with a support mechanism that includes a turning part and a moving part, an image processor, a photographic region assignment receiving part, and a control part to simplify the operation of moving the support to a predetermined starting position for pseudo intraoral radiography, allowing for easy selection and adjustment of photographic regions and irradiation angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If intraoral radiography is performed with X-ray detection means disposed in a mouth cavity, then the mechanical configuration is simplified, but the burden on the patient increases and positioning accuracy deteriorates
Solution Approach 1:
A positioning guide structure with multiple positioning protrusions and corresponding positioning grooves is introduced as an intermediary mechanism. This guide ensures accurate relative positioning between the X-ray generator and detector without requiring manual alignment by the operator, thereby maintaining simplicity while improving positioning accuracy
Solution Approach 2:
The positioning guide structure is pre-configured with specific positioning protrusions and grooves that automatically align the X-ray generator and detector when the apparatus is assembled. This preliminary arrangement eliminates the need for complex real-time adjustments during operation
2Measurement precision
If panoramic photography is performed with a turning arm mechanism, then positioning accuracy is improved, but the device complexity increases and operation becomes more troublesome
Solution Approach 1:
The complex turning arm mechanism is extracted and replaced with a simplified support structure that holds the X-ray generator and detector in fixed relative positions. The positioning guide structure takes over the alignment function, eliminating the need for mechanical turning arms while maintaining positioning accuracy
Solution Approach 2:
The positioning guide structure is designed to automatically align and position the X-ray generator and detector through its own geometric features (protrusions and grooves) without requiring external control mechanisms or complex operations by the user
3Device complexity
If manual operation is required to move the support to the turning start position, then the device structure is simplified, but the operation becomes troublesome and productivity decreases
Solution Approach 1:
The support structure is designed with self-positioning features including positioning protrusions that automatically guide the support to the correct starting position when the apparatus is assembled or reset. This eliminates the need for manual operation to move the support to the turning start position, improving productivity while keeping the device structure simple
