Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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
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
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
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
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
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
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
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
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

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').
