Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lifting platforms in medical devices face safety issues due to unreliable locking mechanisms, which can lead to unintended movement during debugging or repair, potentially causing injury, and misoperation risks.
Innovation Solution
A lifting platform with a locking assembly and a detachable locking state switching assembly that allows for secure locking and unlocking, preventing unwanted movement and simplifying the locking operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional locking apparatuses are mounted on the lifting platform to support or fasten the support platform, then the support platform can be locked during debugging or repair, but the device complexity increases and reliability decreases due to potential loss or misplacement of locking apparatuses
Solution Approach 1:
The locking apparatus is merged with the support assembly structure. The locking component integrates the support function and locking function into a single unified structure, eliminating the need for separate locking apparatuses. This reduces device complexity while maintaining locking reliability through the integrated design where the locking component is inherently part of the support mechanism.
Solution Approach 2:
The support assembly provides self-locking capability through its own structural components. The locking component utilizes the existing support structure elements to achieve locking without requiring external locking apparatuses. The support assembly serves its own locking needs through the integrated locking component, eliminating dependency on separate locking devices that could be lost or misplaced.
2Ease of operation
If a locking apparatus is removed from the lifting platform to unlock the support platform, then the support platform can move freely, but safety problems may occur due to misoperation or forgotten locking
Solution Approach 1:
The locking component transitions between locked and unlocked states through dynamic structural changes. The support assembly can switch between a locked configuration (during debugging/repair) and an unlocked configuration (during normal operation) through controlled movement of the locking component. This dynamic capability allows easy state switching while maintaining safety through deliberate operational procedures.
Solution Approach 2:
Instead of requiring active removal of locking apparatuses to unlock, the system uses the presence or absence of the locking component in its operational position to determine locked vs. unlocked states. The locking component naturally assumes a locked position when installed, and unlocking occurs when it is deliberately repositioned or removed, inverting the conventional approach and reducing misoperation risks.

AI summary
A lifting platform of a medical device includes a base; a support platform, disposed on an upper side of the base; a support assembly, connecting the support platform and the base; a drive assembly, connected to the support assembly and driving the support assembly to move for lifting and lowering the support platform; a locking assembly, connected to the support assembly and used to lock movement of the support assembly; and a locking state switching assembly, detachably connected to the locking assembly to switch the locking assembly between a locked state and an unlocked state, wherein when the locking state switching assembly is connected to the locking assembly, the locking assembly is in an unlocked state, and the support assembly is capable of moving freely; and when the locking state switching assembly is separated from the locking assembly, the locking assembly is in a locked state, and movement is prevented.
