Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anchors for concrete lack optimal strength and performance, particularly in the configuration of their head portion, which affects their ability to effectively lift concrete bodies.
Innovation Solution
The anchor design includes a head with a lifting aperture and legs for embedment, featuring a ribbed structure with a curved and straight rib configuration, a cross rib extending between legs, and webbing that forms an I-beam section, enhancing rigidity and resistance to folding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the head configuration is simplified, then manufacturing is easier, but strength and rigidity are reduced
Solution Approach 1:
The head is segmented into multiple functional zones: lifting aperture region, additional aperture region, rib structures (curved and straight), cross rib, and webbing. Each segment serves a specific structural purpose, allowing the head to achieve high strength through distributed load paths while maintaining manufacturing simplicity through modular design elements that can be formed using standard fabrication processes.
Solution Approach 2:
The design transitions from a simple planar head structure to a three-dimensional configuration with vertical ribs, horizontal cross ribs, and webbing connections. This dimensional enhancement creates an I-beam cross-section that provides superior moment of inertia and bending resistance, significantly improving strength without complicating the manufacturing process.
2Device complexity
If the head configuration is simplified, then device complexity is reduced, but rigidity and resistance to folding are reduced
Solution Approach 1:
The curved rib portion introduces geometric curvature into the head structure, creating an arch-like form that naturally resists bending and folding forces. This curved geometry distributes stresses more effectively than straight lines and adds structural rigidity without requiring complex assembly procedures.
Solution Approach 2:
The head functions as a composite structural system combining multiple geometric elements (curved ribs, straight ribs, cross ribs, and webbing) into an integrated I-beam configuration. This composite approach creates a structure with superior stiffness-to-weight ratio and resistance to folding, while each individual element remains simple to manufacture.
3Ease of manufacture
If the head configuration is simplified, then manufacturing is easier, but shear resistance is reduced
Solution Approach 1:
The design merges the curved rib, straight ribs, cross rib, and webbing into an integrated I-beam structure that acts as a unified load-bearing element. This merging creates continuous load paths that effectively transfer shear forces across the head, providing enhanced shear resistance while maintaining manufacturing simplicity through streamlined fabrication processes.

AI summary
An anchor for embedment in a concrete body for lifting the concrete body, wherein the anchor includes a head having a lifting aperture for engagement with a lifting device, and a pair of legs adapted for embedment within the concrete body, wherein the head has an additional aperture having at least a portion of the additional aperture bordered by a border rib, wherein a lower edge of the head is provided with a cross rib which extends between the pair of legs, and wherein webbing extends between the border rib and the cross rib such that a cross-section along a longitudinal axis of the anchor between the cross rib and the border rib forms an I-beam.
