Solution Overview

Problem

Existing scaffolding systems face challenges in securely and efficiently attaching scaffolding posts to beams with 10-centimeter or multiple-of-10 centimeter spacings, as current solutions are either statically problematic or costly due to the need for precise measurement and adaptation.

Innovation Solution

A post connection adapter with multiple fastening positions and configurations, including U-profile members and circularly cylindrical bores, allows for detachable and stable fastening of scaffolding posts to beams with 100-millimeter or multiple-of-100 millimeter spacings, enabling parallel alignment of post axes and flexible mounting options.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If coupling adapters are used to connect scaffolding posts to beams with 10-centimeter spacings, then the connection can be achieved, but the solution becomes statically problematic and more expensive due to the need for precise measurement and adaptation

Engineering Contradiction:

Improveadaptability to beam fastening positionsVSAvoidstatic stability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The adapter is divided into two distinct bodies: a fastening body with multiple fastening positions for attaching to the beam, and a post connection body for connecting the scaffolding post. This segmentation allows each body to be optimized for its specific function, providing both adaptability to different beam positions and reliable post connection through specialized interfaces

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The adapter acts as an intermediary component between the beam and the scaffolding post. It includes a fastening body that interfaces with beam fastening positions and a post connection body that interfaces with the post, thereby mediating the connection between components with different spacing requirements and connection mechanisms

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If multiple types of adapters are used to achieve various system axial dimensions, then different spacing requirements can be met, but the device complexity and cost increase

Engineering Contradiction:

Improverange of system axial dimensionsVSAvoidnumber of adapter types

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The adapter is designed as a universal component that can accommodate multiple system axial dimensions (732mm, 1088mm, 1572mm, 2072mm, 2772mm, 3072mm) through a single design. The fastening body provides multiple fastening positions that can be selectively used to achieve different spacing requirements, eliminating the need for multiple specialized adapter types

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The adapter incorporates adjustable and selectable features that allow it to dynamically adapt to different spacing requirements. The multiple fastening positions on the fastening body enable selective configuration to match various system axial dimensions, providing flexibility without requiring multiple fixed-design adapters

Inventive Principle:

Principle #15Dynamics

3Ease of operation

If adapters with slots and screws are used to allow displacement for achieving desired system axial dimensions, then positioning flexibility is improved, but the solution becomes problematic from the static aspect and expensive

Engineering Contradiction:

Improvepositioning flexibilityVSAvoidstatic stability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The adapter separates the positioning function (multiple fastening positions on the fastening body) from the connection function (post connection body with apertured disc and wedge). This segmentation allows for easy positioning selection while maintaining a simple, reliable connection mechanism that does not require complex slots and screws

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention replaces the complex slot-and-screw adjustment mechanism with a simpler system based on selective fastening position selection and a wedge-based locking mechanism. The wedge replaces the need for screws and nuts, providing both positioning flexibility and static stability through a more straightforward mechanical approach

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A post connection adapter for detachably fastening a scaffolding post to a support includes a fastening body having first and second fastening-body fasteners in first and second fastening-body fastening positions, respectively, and detachably fastenable to the support selectively by the first or second fastener. The first and second positions have a fastening position distance between each other of 72 mm. The post connection adapter includes a post connection body extending toward the post connection body axis and fastened to the fastening body. An imaginary center plane containing an imaginary center point between the first and second positions is offset by 20 mm perpendicular to the center plane and to the post connection body axis, with respect to a post connection body axis plane extending parallel to the center plane and containing the post connection body axis. A device has two identical post connection adapters detachably fastened to a support.
