X-ray Detector Support Mechanism for Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing X-ray detecting apparatuses suffer from reduced supporting stability due to the large vertex angle of the triangle formed by hinges, leading to increased forces acting on the linear actuator, which compromises the stability of the X-ray detector when its direction is changed.
Innovation Solution
An X-ray detecting apparatus with a support mechanism that includes a hinge on the side opposite to the X-ray incidence plane, a shaft connected to the X-ray detector through a hinge, and a linear actuator driving the opposite end of the shaft in a horizontal direction, enhanced by a linear guide for improved stability, allowing the X-ray detector to be supported in a cantilevered fashion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the linear actuator is used to support the X-ray detector in a horizontal state, then the X-ray detector can be positioned horizontally, but the supporting stability deteriorates due to the large vertex angle of the triangle formed by the hinges
Solution Approach 1:
The invention changes the geometric parameters of the support mechanism by introducing a shaft that forms a different triangle configuration with the hinges. This alters the vertex angle from large (obtuse) to smaller values, thereby changing the force distribution parameters and improving stability while maintaining the horizontal detector position
2Shape
If the triangle formed by hinges has a large vertex angle, then the X-ray detector can be positioned horizontally, but the force acting on the linear actuator increases several times
Solution Approach 1:
The shaft acts as an intermediary mechanical element between the linear actuator and the X-ray detector. It transfers and redistributes the forces through a different geometric path, reducing the amplification effect caused by the large vertex angle and decreasing the force burden on the linear actuator
3Adaptability or versatility
If the X-ray detector direction is made changeable, then the apparatus can adapt to different irradiating directions, but the supporting stability deteriorates
Solution Approach 1:
The invention creates a dynamic support system where the shaft and linear actuator work together to maintain stability during directional changes. The mechanism allows the detector to rotate between horizontal and vertical states while the shaft adjusts its angle, dynamically redistributing forces to maintain stability throughout the range of motion
