Lifting Platform Locking Assembly for Preventing Table Drops
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lifting platforms in medical devices require additional locking apparatuses to prevent unexpected displacement of the support table, which can lead to safety issues if the locking apparatuses are lost or not installed, posing a risk of sudden table drops.
Innovation Solution
A lifting platform with a locking assembly that includes a blocking member and a lock status switching member, allowing for secure locking by simply removing the status switching member, thereby preventing movement of the support assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional locking apparatuses are installed to support or fasten the support table, then the reliability of preventing unexpected displacement is improved, but the device complexity and ease of operation deteriorate
Solution Approach 1:
The patent combines the locking apparatus with the support assembly into an integrated locking assembly. The blocking member is movably mounted on the body member that is connected to the support assembly, merging the locking function with the existing support structure. This eliminates the need for separate additional locking apparatuses while maintaining the reliability of preventing unexpected displacement.
Solution Approach 2:
The locking assembly serves multiple functions: it provides locking capability through the blocking member, integrates with the support assembly structure, and includes a lock status switching member for operational control. This multi-functionality reduces the need for separate dedicated locking components.
2Reliability
If additional locking apparatuses are installed to support or fasten the support table, then the reliability of preventing unexpected displacement is improved, but the ease of operation deteriorates
Solution Approach 1:
The patent inverts the traditional locking operation logic. Instead of requiring installation of locking apparatuses to achieve locking, the system is designed so that locking is achieved by removing the lock status switching member from the locking assembly. This inversion simplifies the operation to a single removal action rather than complex installation procedures.
Solution Approach 2:
The locking assembly is designed to be self-sufficient with the blocking member automatically preventing movement when the lock status switching member is removed. The system serves itself by using the removal of one component (lock status switching member) to automatically engage the locking function through the blocking member, without requiring additional operational steps.
3Ease of repair
If locking apparatuses are made removable for maintenance access, then the ease of repair is improved, but the reliability of preventing unexpected displacement deteriorates
Solution Approach 1:
The locking assembly is segmented into distinct components: the body member connected to the support assembly, the movably mounted blocking member, and the detachably connected lock status switching member. This segmentation allows the lock status switching member to be removed for maintenance access while the blocking member remains integrated with the support assembly to maintain locking reliability.
Solution Approach 2:
The blocking member is designed with movable capability on the body member, allowing it to dynamically transition between locked and unlocked positions. This dynamic design enables the blocking member to maintain reliable locking when engaged while allowing easy removal of the lock status switching member for maintenance purposes.

AI summary
Provided in embodiments of the present application are a lifting platform and a medical device. The lifting platform includes: a base; a support table disposed on an upper side of the base; a support assembly connecting the support table and the base and driving the support table to lift; a locking assembly including a body member connected to the support assembly and a blocking member movably mounted on the body member, wherein the blocking member prevents movement of the support assembly when moving to a first position abutting against the base; and a lock status switching member detachably connected to the locking assembly, wherein the blocking member moves to the first position when the lock status switching member is removed from the locking assembly.
