Solution Overview

Problem

Existing scaffolding anchoring devices struggle with effectively absorbing transverse loads on thermally insulated facades, leading to potential detachment and thermal bridge formation, while being expensive and complex to manufacture.

Innovation Solution

A scaffolding anchoring device with a plastic base body, preferably reinforced with glass fibers, featuring a tapered design and reinforcing ribs for load distribution, and a threaded element injected into the base body for secure attachment, which can absorb pressure, tensile, and transverse loads without forming thermal bridges.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a metal load distribution part is used to absorb transverse loads, then the stability and load-bearing capacity are improved, but thermal bridges are formed that negatively impact facade insulation properties

Engineering Contradiction:
Improveload-bearing capacityVSAvoidthermal bridge formation
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The material parameter of the load distribution part is changed from metal to plastic, fundamentally altering the thermal conductivity while maintaining load-bearing capability through geometric optimization and reinforcement strategies

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

A composite structure is employed combining plastic base body with embedded metal threaded elements and glass fiber reinforcement, achieving both thermal insulation and mechanical strength through material composition rather than homogeneous material selection

Inventive Principle:
Principle #40Composite materials

2Stability of the object's composition

If a complex metal construction with additional supports is used to absorb loads, then the stability is improved, but the manufacturing cost and assembly complexity increase

Engineering Contradiction:
ImprovestabilityVSAvoidconstruction complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

Multiple functions (load distribution, thermal insulation, anchoring, and reinforcement) are merged into a single integrated plastic base body component, eliminating the need for separate metal supports and simplifying both manufacturing and assembly

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The plastic base body serves multiple purposes simultaneously: it distributes loads through its geometric design, provides thermal insulation, anchors the threaded elements, and incorporates reinforcement features, making it a universal component that replaces multiple specialized parts

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

3Ease of manufacture

If a cylindrical base body is used for the anchoring device, then the ease of manufacture is improved, but the ability to absorb transverse loads is reduced

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidtransverse load absorption
Core Design Contradiction:
Ease of manufactureVSStrength

Solution Approach 1:

The base body geometry transitions from a simple cylinder to an asymmetric shape with radially extending reinforcing ribs, maintaining manufacturing simplicity through mold-based production while significantly enhancing transverse load absorption capability through the rib structure

Inventive Principle:
Principle #4Asymmetry

AI summary

The device (1) has a base body (2) i.e. frustoconical shaped solid body, formed by a boundary area (20) tapered to another boundary area (21), where the base body is designed as a single-piece plastic part. The former boundary area forms an abutment surface for installing the base body at a wall of a building. A connection unit connects the base body to the wall, and another connection unit i.e. eyelet bolt (3), connects a part of a scaffold to the base body, where the two connection units are connected with the base body.
