Temple Supporter Pressure Stop Control for X-Ray Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional X-ray imaging devices in dental clinics apply excessive pressure to the examinee's head, causing discomfort and pain due to manual operation and concentration of pressure at specific points, particularly when the temple supporter moves along an arc shape.
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 switches 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 along the arc shape, then the examinee can be positioned, but excessive pressure is applied causing pain
Solution Approach 1:
The patent incorporates a pressure sensor that detects the pressure applied by the temple supporter on the examinee's head and provides feedback to the control unit. The control unit adjusts the driving force based on this feedback to maintain pressure within a safe range, preventing excessive pressure while ensuring proper positioning.
Solution Approach 2:
The system automatically regulates its own operation through the pressure sensor and control unit, eliminating the need for manual adjustment. The temple supporter self-adjusts the applied pressure based on real-time sensor data, preventing operator error and ensuring consistent, safe pressure application.
2Productivity
If the temple supporter moves along the arc shape, then the examinee can be arranged, but pressure is concentrated at the end causing pain
Solution Approach 1:
The patent employs a pressure-sensitive template with multiple pressure-sensitive elements distributed across its surface. This allows the system to detect pressure distribution at different locations and adjust the temple supporter's position or apply force to balance the pressure distribution, preventing concentration at any single point.
Solution Approach 2:
The system dynamically adjusts the temple supporter's movement along the arc shape based on real-time pressure feedback. The control unit modifies the driving force and position during the movement process to maintain uniform pressure distribution, rather than following a fixed arc path, thereby preventing pressure concentration at the end of the movement.
3Object-affected harmful factors
If automatic pressure control is implemented, then excessive pressure is prevented, but device complexity increases
Solution Approach 1:
The patent replaces manual mechanical operation with an automated control system that uses a pressure sensor and microcontroller unit. This substitution eliminates the need for operator skill and manual adjustment, reducing human error while the compact electronic components minimize the increase in overall device complexity.
