Anchor Fitting Structure for Misaligned Workpiece Recesses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anchoring fittings require precise alignment and installation, as they are sensitive to movement play and alignment issues between workpiece recesses, which can be challenging with non-precisely arranged holes, limiting their adaptability and ease of use.
Innovation Solution
The anchoring fitting design includes a tie rod with increased movement play and alignment transverse width, allowing for adjustable alignment within the plug-in receptacle, and a clamping body with a clamping bevel for secure engagement, along with a support body with abutment body receptacles and guide projections for stable insertion, enabling alignment and secure anchoring in workpieces with varying recess dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the anchoring fitting uses a fixed, precise configuration for reception in workpiece recesses, then the manufacturing precision and stability are improved, but the ease of operation and adaptability to non-precisely aligned holes deteriorate
Solution Approach 1:
The patent changes the dimensional parameters of the support body, specifically increasing the transverse width of the abutment body receptacle and the movement play between the support body and abutment body. This allows the fitting to accommodate variations in hole alignment while maintaining stable operation once installed.
Solution Approach 2:
The patent introduces dynamic adjustment capability through the movable support body within the abutment body receptacle. The support body can move transversely to accommodate alignment variations during installation, then stabilizes in a fixed position during operation, combining adaptability with stability.
2Reliability
If the anchoring fitting reduces movement play for precise alignment, then the stability and reliability are improved, but the adaptability to varying recess dimensions deteriorates
Solution Approach 1:
The support body is designed to be movable during installation to accommodate alignment variations, then becomes fixed during operation to provide stable connection. This dynamic-to-static transition resolves the contradiction between adaptability and reliability.
Solution Approach 2:
The anchoring fitting is divided into separate components: the support body and the abutment body. This segmentation allows the support body to move independently within the abutment body receptacle during installation, providing alignment tolerance, while the clamping mechanism ensures reliable connection once positioned.
3Device complexity
If the anchoring fitting uses a compact design with minimal play, then the device complexity is reduced, but the ease of operation for non-precise alignment deteriorates
Solution Approach 1:
The patent implements a simple dynamic mechanism where the support body can move within the abutment body receptacle. This minimal dynamic feature provides installation flexibility without significantly increasing structural complexity, as it relies on dimensional clearances rather than complex mechanical components.

AI summary
The invention relates to an anchor fitting (10) for anchoring in a workpiece (W2), the anchor fitting (10) comprising a tie rod (50) for arranging in a connection recess (VA) of the workpiece (W2) and an abutment body (20) for arranging in an abutment recess (WA) of the workpiece (W2), said abutment recess communicating with the connection recess (VA), wherein the abutment body (20) comprises a socket (26) for the insertion of an insertion section (52) of the tie rod (50) along an insertion axis (S) and a supporting surface arrangement for support against the abutment recess (WA) of the workpiece (W2), at least one supporting surface of the supporting surface arrangement extends transversely, particularly at a right angle, to a longitudinal axis (L) of the tie rod (50) inserted into the socket (26), in such a way that the tie rod (50) is supported in relation to the longitudinal axis (L) thereof against the abutment recess (WA), the anchor fitting comprises a locking body (60) for locking the insertion section (52) of the tie rod (50) in the socket (26), and at least one supporting body (30) of the anchor fitting has a flat shape with flat sides opposite each other and particularly rounded narrow sides extending between the flat sides, for positive support, at least in sections, in the connection recess (VA) or the abutment recess (WA) of the workpiece (W2). According to the invention, transversely to the insertion axis (S), the socket (26) has an aligning transverse width (Q) suitable for aligning the tie rod (50) in relation to the abutment body (20), said transverse width being larger than the play (BS) required for inserting the tie rod (50) into the socket (26).
