Segmented Platform for Ceiling Carrier Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing maintenance step installation methods for ceiling carrier systems lack ease of placement and safety, particularly in high-height maintenance operations.
Innovation Solution
A raising and lowering device with a frame, rail, and platform where the platform is detachably placed on a raising and lowering part, with protrusions engaging through holes to restrain horizontal movement, allowing for easy installation and segmentation for reduced operator effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the platform is made as a single large structure, then it provides sufficient working surface area, but it becomes difficult to install and requires significant operator strength
Solution Approach 1:
The platform is divided into multiple segments that can be separately handled and installed. Each segment can be easily positioned and connected to the raising and lowering part, allowing installation without requiring excessive operator strength while still providing sufficient total working surface area when segments are assembled together
2Ease of operation
If the platform is made detachable for easy installation, then it can be easily assembled and disassembled, but it may compromise structural stability and safety
Solution Approach 1:
The platform segments are designed to nest onto the raising and lowering part with engagement features that ensure secure attachment. The detachable connection mechanism maintains structural stability through proper engagement while allowing easy installation and removal when needed
3Reliability
If the platform is designed to be securely attached to prevent movement, then safety is improved, but installation becomes more complex
Solution Approach 1:
The secure attachment is achieved through segmented design with simple engagement features on each segment. The engagement mechanism restrains horizontal movement and ensures safety while maintaining simple installation procedures that do not require complex assembly steps

AI summary
In order to easily install a platform, a raising and lowering device includes: a frame; a raising and lowering rail that a conveyance carriage is able to enter; a raising and lowering member configured to be raised and lowered integrally with the raising and lowering rail and to be, when located at a lowering stoppage position, supported by a support part provided to the frame; and a platform configured to be detachably placed on the raising and lowering member, the platform being configured to be placed on the raising and lowering member in a state in which a part of the platform is engaged with a part of the raising and lowering member in a manner so as to restrain the platform from moving in a horizontal direction.
