Clutch Release Mechanism for Medical Tables with Axial Handle Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing CT/MR medical table clutch devices have operation directions that are not aligned with the movement direction of the clutch disc, leading to inconvenience and limited application scenarios due to non-intuitive operation.
Innovation Solution
A clutch release device with a push-pull rail, clutch pull handle, transmission wheel, clutch disc, and connecting rod mechanism, where the clutch pull handle moves parallel to the axial direction of the transmission shaft, allowing synchronized operation and separation of the clutch disc from the transmission wheel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the clutch pull handle operates in a direction different from the clutch disc movement direction, then the clutch device can be compactly arranged, but the operation convenience and intuitiveness deteriorate
Solution Approach 1:
The patent inverts the conventional clutch operation mechanism by making the clutch pull handle move in the same direction as the clutch disc (axial direction), rather than perpendicular to it. This inversion aligns the operator's action direction with the clutch disc movement direction, significantly improving operation convenience and intuitiveness while maintaining compact arrangement through the connecting rod mechanism
2Ease of operation
If the clutch pull handle is aligned with the transmission shaft axial direction, then operation intuitiveness is improved, but the mechanical transmission complexity increases
Solution Approach 1:
The patent introduces a connecting rod mechanism as an intermediary between the clutch pull handle and the clutch disc. This intermediary component translates the linear motion of the pull handle (parallel to transmission shaft axis) into the corresponding axial motion of the clutch disc, achieving intuitive operation while managing the mechanical transmission complexity through a well-defined intermediate mechanism

AI summary
A clutch release device and a medical table, wherein the clutch release device comprises a push-pull rail; a clutch pull handle mounted on the push-pull rail, the clutch pull handle being moveable between a first station and a second station along the push-pull rail; a transmission wheel sleeved outside a transmission shaft located on one side of the push-pull rail, and being rotatable about the transmission shaft; a clutch disc sleeved outside the transmission shaft and located on one side of the transmission wheel, the clutch disc rotating synchronously with the transmission shaft, and the clutch disc being movable between station a and station b along an axial direction of the transmission shaft; and a connecting rod mechanism provided between the clutch disc and the clutch pull handle, the connecting rod mechanism being configured such that when the clutch pull handle is in the first station, the clutch disc is in station a, and the clutch disc is coupled to the transmission wheel, and when the clutch pull handle is in the second station, the clutch disc is in station b, and the clutch disc is separated from the transmission wheel. It is possible to implement the transmission state control between a motor and a table board in the medical table.
