Solution Overview

Problem

Existing scaffolding elements are not easily adaptable to various scaffolding designs, requiring multiple elements for different widths, which increases storage needs and complexity.

Innovation Solution

A scaffolding element with a detachable horizontal bar extension that can be coupled to the horizontal bar, allowing the same element to be used for both standard and wider scaffolding widths by adjusting its length, featuring a hollow design with orthogonal connection openings for secure attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple scaffolding elements with different horizontal bar lengths are kept in stock to adapt to various scaffolding widths, then adaptability is improved, but device complexity and storage requirements increase

Engineering Contradiction:
Improveadaptability to various scaffolding widthsVSAvoidnumber of different scaffolding elements
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The horizontal bar is divided into a base horizontal bar and a detachable extension element. The extension element can be coupled to the horizontal bar via a coupling mechanism (such as a coupling element inserted into a coupling opening) to extend the horizontal bar's length. This segmentation allows a single base element to serve multiple width requirements when combined with different extension elements.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The scaffolding element incorporates adjustable and detachable components, specifically the horizontal bar extension mechanism that can be dynamically configured. The extension element can be attached or detached from the horizontal bar depending on the required scaffolding width, transforming a static fixed-length bar into a dynamic adjustable-length bar.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If telescopic horizontal beam extension elements are used to adjust horizontal bar length, then adaptability is improved, but device complexity and locking mechanisms increase

Engineering Contradiction:
Improveadjustability of horizontal bar lengthVSAvoidlocking mechanisms for extension elements
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Instead of using a complex telescopic mechanism with multiple locking points, the patent segments the horizontal bar into a fixed base bar and a detachable extension element. The coupling mechanism consists of a coupling element on the extension element that inserts into a coupling opening on the horizontal bar, providing a simpler alternative to telescopic locking systems.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent extracts the extension functionality from the main horizontal bar structure and implements it as a separate detachable element. This allows the extension feature to be added or removed independently, simplifying the main horizontal bar design while maintaining adjustability capabilities.

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of operation

If the horizontal bar is designed as a hollow component with coupling areas, then ease of connection is improved, but manufacturing complexity increases

Engineering Contradiction:
Improveease of connecting extension elementVSAvoidhollow component fabrication
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The hollow horizontal bar design serves multiple functions: it provides structural strength, creates internal space for the coupling mechanism, and allows for the integration of connection points. The coupling opening is formed in the hollow bar structure, enabling the extension element to connect internally, which simplifies the external appearance while maintaining connection functionality.

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

AI summary

A scaffolding element, in particular for a construction scaffold, comprises a vertical beam (14) to be oriented substantially vertically and a horizontal beam (16) to be oriented substantially horizontally and extending away from the vertical beam (14), wherein the horizontal beam (16) has a first scaffolding connection formation (24) in its free end area (22) positioned away from the vertical beam (14) for connecting the horizontal beam (16) in its free end area (22) to a scaffold (10), further comprising a horizontal beam extension element (34) that is detachably attached or attachable to the free end area (22) of the horizontal beam (16).
