Scaffolding Platform Offset Wall Design for Snag-Free Stacking

Solution Overview

Problem

Existing scaffolding decks made of light metal extruded profiles face challenges with high production and assembly costs, limited resistance to harsh use conditions, and premature deformation due to improper use, leading to early replacement.

Innovation Solution

The scaffolding floor design features a floor profile wall with offset areas and a projection unit that prevents snagging when stacking, combined with a steel end cross-connection system for enhanced rigidity and load capacity, allowing for easy handling and stacking while eliminating the risk of decks catching during assembly and disassembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Weight of moving object

If light metal extruded profiles are used for floor profile units, then weight is reduced and ease of manufacture is improved, but strength and resistance to harsh use conditions deteriorate

Engineering Contradiction:
Core Design Contradiction:
Weight of moving objectVSStrength

Solution Approach 1:

The scaffolding floor combines light metal extruded profile parts for the floor profile units with steel end cross-connection means and steel reinforcement structures (L or T webs). This composite construction allows the majority of the structure to be made of lightweight aluminum while using steel only where high strength is required (connection points and reinforcement), thus reducing overall weight while maintaining sufficient strength and resistance to harsh conditions.

Inventive Principle:
Principle #40Composite materials

2Ease of manufacture

If end connection means are made of light metal profiles, then ease of manufacture is improved, but reliability and resistance to deformation deteriorate

Engineering Contradiction:
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The invention applies different material qualities to different parts of the structure: light metal extruded profiles are used for the floor profile units where lower strength is acceptable, while steel material is specifically used for the end cross-connection means and reinforcement structures where high strength and deformation resistance are critical. This localized material selection optimizes both manufacturability and reliability.

Inventive Principle:
Principle #3Local quality

3Ease of operation

If hook-in claws are positioned at the bottom edge, then ease of operation for suspension is improved, but harmful factors increase due to snagging during stacking

Engineering Contradiction:
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The invention resolves the snagging problem by moving the hook-in claws from the bottom edge plane to a higher position on the end cross-connection means. The claws are arranged to engage with the suspension structure from above rather than from the bottom edge, changing the spatial dimension of the connection. This elevation prevents the claws from interfering with the stacking operation while maintaining their suspension function.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

4Strength

If reinforcement structures are added to increase rigidity, then strength is improved, but device complexity increases

Engineering Contradiction:
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The reinforcement structures are designed as separate, modular components (L webs or T webs) that can be independently manufactured and then assembled to the floor profile units. This segmentation allows for simplified manufacturing of individual parts while achieving the required rigidity through their coordinated arrangement. The modular nature also simplifies assembly and potential maintenance.

Inventive Principle:
Principle #1Segmentation

AI summary

The platform (10) has a base profiled wall (30) with a displacement area (36) that is displaced outwards around a displacement dimension relative to a lower side of the wall. Another displacement area (38) is attached outwards to the former displacement area and exhibits another displacement dimension relative to the lower side, where the latter dimension is larger than the former dimension. The areas are formed such that a projection unit (32) of a lower platform is arranged in an area below the former area of a stacked platform during stacking of the platforms on top of each other.
