Trough Subframe Unit for Scaffold Assembly and Liquid Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scaffolding systems lack effective protection for personnel and efficient assembly and disassembly methods, especially when dealing with large and heavy substructure units, and they often require cumbersome sealing and risk leaks during liquid-based operations.
Innovation Solution
A substructure unit with a platform base designed as a trough, featuring locking mechanisms and anchoring means for secure support column attachment, allowing for machine-assisted assembly and disassembly, and incorporating telescopic support columns for adjustable height and compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If support columns are pushed through the platform from top to underside, then assembly is simplified, but reliable locking and immovable positioning becomes difficult to achieve
Solution Approach 1:
The support column is divided into a leg portion and a head portion, with the head being insertable through the platform while the leg remains externally accessible. This segmentation allows the column to serve dual purposes: passing through the platform for structural integration while maintaining external access for reliable locking mechanisms.
Solution Approach 2:
A locking mechanism acts as an intermediary element between the support column head and the platform. This intermediary component secures the column in its pushed position, preventing unintended movement while maintaining the simplified assembly process of pushing the column through the platform.
2Object-affected harmful factors
If base body is designed as a tub, then protection from liquids and falling objects is improved, but device complexity increases
Solution Approach 1:
The base body is designed as a tub that simultaneously serves multiple functions: it acts as a protective barrier against falling objects, creates a liquid-tight containment area for collecting liquids and viscous media, and provides structural support for the platform. This multi-functionality reduces the need for separate protective structures.
Solution Approach 2:
The protective function against falling objects and the liquid containment function are merged into a single tub structure. Instead of having separate protective barriers and drainage systems, the tub integrates both functions, simplifying the overall base body design while maintaining comprehensive protection.
3Adaptability or versatility
If support columns are made telescopic, then adjustability and compact storage are improved, but manufacturing precision requirements increase
Solution Approach 1:
The telescopic support column employs a nested structure where one cylindrical section is inserted within another, similar to nested dolls. This nesting arrangement enables compact storage when the column is retracted and provides smooth telescopic movement for height adjustment, while the cylindrical geometry simplifies manufacturing compared to complex mechanical telescopic mechanisms.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides enhanced protection from liquids and falling objects, simplifies assembly and disassembly with machine support, reduces the risk of leaks, and allows for efficient drainage and storage, enabling quick and safe operation on facades.
Implementation Method 1
the support column being able to be pushed into the receptacle with its leg from the top of the platform... the platform with the crane or the forklift is lifted in such a way that the support columns remain stationary on the ground due to gravity
