Solution Overview

Problem

Existing plug-in connection elements for scaffolding lack a consistent installation position, leading to variable height positioning of vertical beams when changing scaffolding depths, due to the design-dependent positioning influenced by lift-off safety elements.

Innovation Solution

A plug-in connection element with an adjustable spacer element and a U-shaped connection section, featuring a hollow plug-in connection mandrel and ring-like stop sleeve, ensures stable and consistent positioning by allowing the spacer element to be displaced and locked relative to the connecting element body, using locking openings and a locking element to maintain alignment with other scaffolding components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If lift-off safety elements are used to secure hooks in U-profile beams, then safety against unintentional detachment is improved, but the positioning of plug-in connection elements becomes variable depending on the design and thickness of the anti-lift elements

Engineering Contradiction:
Improvesafety against unintentional detachmentVSAvoidpositioning consistency of plug-in connection elements
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

A spacer element is introduced as an intermediary component between the U-profile beam and the plug-in connection element. This spacer absorbs the variability in anti-lift element thickness and provides a consistent reference surface, ensuring that the plug-in connection element is positioned at a uniform height regardless of the anti-lift element design.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The connection system is divided into separate functional components: the U-profile beam with anti-lift elements, the spacer element, and the plug-in connection element. This segmentation allows each component to be optimized independently while maintaining overall positioning consistency through the spacer interface.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If variable scaffolding depths are implemented with lower depth in upper area, then adaptability to different construction needs is improved, but the ability to connect vertical bars by plugging them into one another is lost

Engineering Contradiction:
Improvevariable scaffolding depthsVSAvoidconnectability of vertical bars
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system transitions from a fixed connection method (direct plugging of vertical bars) to a dynamic, adaptable connection system using plug-in connection elements with spacers. This allows the scaffolding depth to be dynamically adjusted while maintaining connection capability through the standardized plug-in interface.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The plug-in connection element serves multiple functions: it provides a connection interface for vertical bars, accommodates variable scaffolding depths through adjustable spacers, and ensures consistent positioning. This multi-functionality enables both adaptability and ease of operation in the same component.

Inventive Principle:
Principle #6Universality (Multi-functionality)
