Solution Overview

Problem

Existing shell and wall anchors face challenges in handling on construction sites due to issues with ball-and-socket connections being either too tight or having excessive play, which affects mobility and requires adjustments for different structural distances.

Innovation Solution

An anchoring element with a sleeve-like coupling and thread arrangement that allows adjustable contact pressure, featuring a blocking element to prevent overtightening and a length adjustment mechanism using a hollow rod or sleeve with internal and external threads, enabling precise positioning and length adaptation without grinding or welding.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the ball-and-socket connection is made tight to secure the anchor part, then the anchor part has a secure fit in the coupling element, but the mobility of the anchor part is impaired and it may jam

Engineering Contradiction:
Improvesecure fit of anchor partVSAvoidmobility of anchor part
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent applies parameter changes by introducing a threaded arrangement that allows continuous adjustment of the contact pressure between the anchor part and coupling element. By rotating the threaded component, the axial position and thus the contact pressure can be precisely controlled to achieve optimal values that balance security and mobility

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent implements dynamics by making the contact pressure adjustable rather than fixed. The threaded arrangement enables the system to adapt the tightness of the connection dynamically, allowing the anchor part to maintain both secure fitting and sufficient mobility for adjustment purposes

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the ball-and-socket connection is made loose to maintain mobility, then the anchor part can move freely, but excessive play develops and the anchor function is impaired

Engineering Contradiction:
Improvemobility of anchor partVSAvoidanchor function
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The threaded arrangement enables precise control of the contact pressure parameter, allowing it to be adjusted to the optimal value that prevents excessive play while maintaining necessary mobility for installation and adjustment

Inventive Principle:
Principle #35Parameter changes

3Reliability

If the threaded arrangement is made adjustable to optimize contact pressure, then the mobility and secure fit are balanced, but the device complexity increases

Engineering Contradiction:
Improvebalanced secure fit and mobilityVSAvoidthreaded arrangement structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The anchoring element is divided into separate components including the coupling element, anchor part, and threaded arrangement components. This segmentation allows the threaded adjustment mechanism to be integrated without requiring complete redesign of the entire anchor structure

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The threaded arrangement acts as an intermediary mechanism between the coupling element and anchor part, providing the adjustment function without directly modifying the fundamental ball-and-socket connection structure

Inventive Principle:
Principle #24Intermediary (Mediator)

4Ease of operation

If locking elements are added to prevent overtightening, then the optimal position is determined and mobility is preserved, but the manufacturing complexity increases

Engineering Contradiction:
Improveprevention of overtighteningVSAvoidmanufacturing of locking elements
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The locking elements are pre-integrated into the coupling element or second anchor part during manufacturing. This preliminary action ensures that the maximum travel of the threaded arrangement is limited from the outset, preventing overtightening before it can occur during installation

Inventive Principle:
Principle #10Preliminary action

AI summary

The invention relates to an anchoring element (1, 101, 101') for a multi-part anchor (200) for connecting two concrete components that are movable relative to each other. The anchoring element (1, 101, 101') comprises a first anchor part (2, 102) and a second anchor part (4, 104, 104') arranged on the first anchor part (2, 102) by means of a sleeve-like coupling element (3). The first anchor part (2, 102) comprises a head element (5) such that the first anchor part (2, 102) is movably arranged relative to the second anchor part (4, 104, 104') in the coupling element (3), approximately in a ball-and-socket manner. The coupling element (3) can be fastened to the second anchor part (4, 104, 104') by means of a threaded arrangement (8). On the second anchor part (4, 104, 104') and/or on the coupling element (3) at least one locking element (9) is provided, with which the end position of the threaded arrangement (8) relevant for the assembly of the anchoring element (1, 101, 101') is determined.Alternatively or cumulatively, a length adjustment arrangement (120, 120') can be provided for the anchoring element (1, 101, 101').
