Medical Device Adjustment Assembly for Vertical Locking Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical devices connected to bases that are not absolutely horizontal can experience component forces, leading to fatigue or damage due to the vertical action of gravity, making it difficult to maintain a stable vertical state.
Innovation Solution
An adjustment device with a rotating shaft and locking mechanism that allows the medical device to be adjusted to a vertical state and locked in place, preventing external thrust-induced rotation, comprising a first and second connection portion, a rotating shaft, and a locking mechanism with a limit portion and locking grooves to ensure stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the medical device is fixedly connected to the base, then the connection is stable, but the base must be at absolute level which is very difficult to guarantee
Solution Approach 1:
The patent transforms the static fixed connection into a dynamic adjustable connection. The adjustable support leg with telescopic structure allows the base to adapt to non-level surfaces, while the locking mechanism maintains stability once positioned. This resolves the contradiction by making the connection dynamically adaptable rather than statically fixed.
Solution Approach 2:
The patent changes the parameter of connection rigidity from fixed to adjustable. The support leg can be extended or retracted to different lengths, and the locking mechanism can engage at different positions, allowing the base to compensate for surface irregularities while maintaining connection stability.
2Adaptability or versatility
If the base is not absolutely horizontal, then the medical device can be installed on uneven surfaces, but component forces are produced causing fatigue or damage
Solution Approach 1:
The adjustable support leg with locking mechanism allows the base to dynamically adapt to uneven surfaces while maintaining horizontal alignment. The locking mechanism ensures that once the adjustable leg is positioned, the connection becomes rigid and stable, preventing fatigue from continuous adjustment or vibration during operation.
Solution Approach 2:
The locking mechanism prevents the harmful effect of base tilting by proactively securing the adjustable leg in the correct position before operational forces are applied. This preliminary locking action counteracts the potential development of component forces that would otherwise cause fatigue or damage.
3Ease of operation
If the medical device is adjustable to vertical state, then the device can be positioned correctly, but the position must be maintained against external thrust
Solution Approach 1:
The system transitions from a static fixed connection to a dynamic adjustable connection during installation, then back to a stable locked state during operation. The adjustable support leg allows positioning adjustments, and the locking mechanism maintains the vertical state against external thrust by preventing further movement once positioned.
Solution Approach 2:
The locking mechanism is designed to engage after the adjustable leg has been positioned in the desired vertical orientation. This preliminary positioning followed by locking ensures that the device can be adjusted to the correct vertical state and then securely maintained against external forces during operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The adjustment device effectively maintains medical devices in a vertical state, reducing the risk of fatigue and damage by allowing adjustment to a perpendicular position and locking it securely, thus ensuring structural stability and preventing external forces from causing tilting.
Implementation Method 1
a rotating shaft, wherein the first connection portion and the second connection portion are rotatably connected through the rotating shaft, so that the first connection portion and the second connection portion rotate relative to each other
Implementation Method 2
a locking mechanism; wherein the locking mechanism comprises a locked state and an unlocked state; in the locked state, the locking mechanism restricts the first connection portion and/or the second connection portion to rotate relative to the rotating shaft

AI summary
An adjustment device and a medical system are for adjusting a medical device. The adjustment device includes a first connection portion for hoisting the adjustment device, a second connection portion is for connecting the medical device, and a locking mechanism. The first connection portion and the second connection portion are rotatably connected through the rotating shaft, so that the first connection portion and the second connection portion rotate relative to each other. The locking mechanism has a locked state and an unlocked state. In the unlocked state, the first connection portion and/or the second connection portion rotate relative to the rotating shaft, to adjust the medical device to a vertical position. In the locked state, the locking mechanism restricts the first connection portion and/or the second connection portion to rotate relative to the rotating shaft, to maintain the medical device in a vertical state.
