Movable Support Body for Elevating Scaffold in Article Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing article storage facilities with tall shelves face limitations in maintenance accessibility due to a single fixed working height, restricting maintenance operations on elevated sections.
Innovation Solution
An article storage facility with a movable elevating scaffold and multiple working heights, supported by movable support bodies that can retract to allow the scaffold to move below, enabling maintenance across various heights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single fixed working height is provided for the elevating scaffold, then the device complexity is reduced, but the maintenance accessibility for tall shelves is limited
Solution Approach 1:
The support body is designed to be movable between a protruding state (where it supports the elevating scaffold at a working height) and a retracted state (where it allows the scaffold to move below). This dynamic capability enables multiple working heights without requiring multiple fixed support structures, thus improving maintenance accessibility while controlling device complexity
Solution Approach 2:
The support body is divided into movable and stationary portions, allowing it to change its position relative to the elevating scaffold. This segmentation enables the support body to provide support at different heights as needed, rather than being fixed at a single height
2Reliability
If the support body protrudes toward the movement space to support the elevating scaffold, then the scaffold can be stabilized at working height, but the scaffold cannot be moved below the support body height
Solution Approach 1:
The support body transitions from a static protruding structure to a dynamic movable structure that can switch between protruding and retracted states. This allows the scaffold to be stabilized when needed (protruding state) and moved freely when the support body is retracted, resolving the contradiction between stability and movement range
3Ease of operation
If multiple fixed support bodies are provided at different heights, then multiple working heights can be achieved, but the support bodies interfere with the elevating scaffold movement
Solution Approach 1:
Instead of providing multiple fixed support bodies that would interfere with scaffold movement, a single support body is made movable between protruding and retracted states. This dynamic approach enables multiple working heights without the interference problems of multiple fixed structures
Solution Approach 2:
The single movable support body serves multiple functions: it can support the scaffold at different heights by changing its position, and it can also retract to allow free scaffold movement. This multi-functionality replaces the need for multiple specialized fixed support bodies

AI summary
An article storage facility includes an elevating scaffold capable of ascending/descending in a movement space across a withdrawal height that is set on an upper side and a plurality of working heights that are set in intermediate locations in the movement space in the vertical direction. A plurality of support bodies that support the elevating scaffold are provided in the vertical direction so as to respectively correspond to the plurality of working heights, and at least a support body other than the lowermost support body of the plurality of support bodies is configured to be movable to an acting position at which the support body protrudes toward the movement space so as to support the elevating scaffold and a withdrawal position at which the support body retracts toward the article storage shelf so as not to come into contact with the elevating scaffold moving up and down.
