X-Ray Head Positioning Guide With Automatic Pressure Stop
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional X-ray imaging devices in dental clinics apply excessive pressure to the examinee's head, causing pain due to manual operation and concentration of pressure at the end of the temple supporter's movement.
Innovation Solution
An examinee arranging apparatus with a guide portion that applies pressure through movement, an operating driving portion for controlling movement, an elasticity portion for deformation response, and a switch to stop movement when a reference pressure is reached, preventing excessive force application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation is used to move the temple supporter, then the examinee arranging apparatus can be operated flexibly, but excessive pressure is applied to the examinee's head causing pain
Solution Approach 1:
The patent replaces manual mechanical operation with an automatic driving mechanism. The temple supporter is moved automatically by a driving unit that controls the movement along the arc shape, eliminating the need for manual operation and preventing excessive pressure application through automated pressure control.
Solution Approach 2:
The patent incorporates a pressure detection mechanism that provides feedback on the pressure applied to the examinee's head. This feedback system allows the driving unit to adjust the movement and pressure in real-time, ensuring that pressure remains within comfortable limits while maintaining positioning accuracy.
2Manufacturing precision
If the temple supporter moves along an arc shape, then the examinee's head can be positioned correctly, but pressure concentrates at the end of movement causing pain
Solution Approach 1:
The patent transforms the static arc-shaped path into a dynamic controlled movement system. The driving unit adjusts the movement speed and pressure distribution along the arc path, slowing down or reducing pressure as the temple supporter approaches the end position, thereby preventing pressure concentration while maintaining positioning precision.
Solution Approach 2:
The patent implements a pressure control mechanism that anticipates the pressure concentration issue at the end of the arc movement. By pre-adjusting the driving force and pressure distribution before reaching the end position, the system prevents excessive pressure buildup while ensuring accurate head positioning.

AI summary
Proposed is an examinee arranging apparatus for an X-ray imaging device that automatically stops when the pressure applied to an examinee reaches a reference value. The apparatus includes a guide portion installed to be movable for arranging a posture of a subject by applying pressure to the subject by the movement, an operating driving portion for controlling the movement of the guide portion, an elasticity portion for causing elasticity deformation in response to a repulsive force applying to the guide portion, a switch for controlling the operating driving portion to stop the movement of the guide portion when the elasticity deformation reaches a reference value.
