Work Platform Stability via Support and Stopper Mechanisms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing article storage facilities face challenges with the stability and tilting of vertically movable work platforms during maintenance, as they sway easily due to inadequate support, and the excessive unwinding of suspension wires leads to irregular winding and tilting when raised, complicating manual vertical movement and accurate placement at work heights.
Innovation Solution
The article storage facility incorporates a support mechanism at the work height to stabilize the vertically movable work platform and includes a stopper mechanism to prevent excessive unwinding of suspension wires, allowing for manual operation without electric motors, ensuring stable and accurate vertical movement by preventing further rotation of the winding rotating body when the platform reaches the work height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the vertically movable work platform is merely suspended and supported by suspension wires fed out from the winding rotating body, then the device complexity is reduced, but the stability of the work platform deteriorates causing it to sway easily
Solution Approach 1:
A support is introduced as an intermediary element between the work platform and the ground. This support receives and stabilizes the work platform when it reaches the work height, preventing swaying during maintenance operations without requiring complex active control systems.
Solution Approach 2:
The support is positioned in advance at the work height location. When the work platform descends, it automatically engages with the pre-positioned support, which then provides stabilization before any maintenance work begins, eliminating the need for complex real-time stabilization mechanisms.
2Ease of operation
If the winding rotating body is further rotated to lower the work platform while it is supported, then the ease of operation is improved, but the manufacturing precision deteriorates due to irregular winding of suspension wires
Solution Approach 1:
The stopper means is pre-configured to automatically prevent further rotation of the winding rotating body when the work platform reaches the work height. This preliminary anti-action counteracts the tendency for over-rotation and irregular winding before it can occur, maintaining wire tension and winding precision.
Solution Approach 2:
The stopper means provides mechanical feedback by physically blocking the rotation of the winding rotating body when the platform reaches the correct height. This feedback mechanism ensures that the suspension wires are fed out by the precise amount needed, preventing irregular winding while allowing easy manual operation.
3Stability of the object's composition
If the work platform is supported at the work height, then the stability of the work platform is improved, but the reliability deteriorates due to excessive unwinding of suspension wires
Solution Approach 1:
The stopper means is pre-positioned to automatically prevent over-rotation of the winding rotating body when the work platform reaches the work height. This preliminary anti-action ensures that suspension wires are never fed out in excessive amounts, maintaining proper tension and winding integrity, thereby preserving reliability while enabling platform support.

AI summary
A vertically movable work platform is suspended and supported by a plurality of suspension wires fed out from one or more of winding rotating bodies which is rotated such that the vertically movable work platform is vertically moved by the rotation of the one or more of winding rotating bodies. A support for receiving and supporting the lowering vertically movable work platform at a work height, and a stopper for preventing the rotation of the winding rotating body in a direction which tends to lower the vertically movable work platform when the vertically movable work platform reaches the work height are provided.
