Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing concrete construction elements with anchor rails and edge reinforcement lack effective anchoring mechanisms to efficiently transmit and distribute transverse forces, leading to potential concrete chipping and instability.

Innovation Solution

The reinforcement component, comprising a plate and anchors formed as one piece with an undercut anchoring section, is embedded in the concrete base body, providing enhanced anchoring and force transmission by forming a closed frame with the anchor rail, which is partially covered by the plate, allowing for better force distribution and reduced risk of concrete chipping.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional anchor rails without undercut anchoring sections are used, then the structure is simpler to manufacture, but the anchoring effectiveness and force transmission capability are reduced

Engineering Contradiction:

Improveanchoring effectivenessVSAvoidmanufacturing complexity

Core Design Contradiction:

StrengthVSEase of manufacture

Solution Approach 1:

The anchoring section is formed with a curved or bent geometry creating an undercut shape, transforming straight anchor bars into hooks or bends that interlock with concrete, significantly improving anchoring effectiveness while remaining manufacturable through standard bending processes

Inventive Principle:

Principle #14Spheroidality (Curvature)

2Strength

If anchors extend below the anchor rail, then anchoring depth is increased, but the overall size and installation difficulty increase

Engineering Contradiction:

Improveforce transmissionVSAvoidinstallation ease

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

The anchors are positioned to extend along the sides of the anchor rail and cover its interior when viewed in longitudinal direction, allowing the anchors to work within the spatial envelope of the anchor rail assembly, improving force transmission without significantly increasing overall dimensions or installation complexity

Inventive Principle:

Principle #7Nested doll (Nesting)

3Ease of manufacture

If the plate and anchors are manufactured separately and connected, then manufacturing flexibility is maintained, but the reinforcement component complexity and assembly steps increase

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidcomponent assembly

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

The plate and at least two anchors are formed as one piece through monolithic manufacturing, eliminating separate connection steps and reducing assembly complexity, while the entire reinforcement component can be produced as a single integrated element ready for direct installation

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A concrete construction element has a concrete base body with at least one flat side and an end face. An anchor rail is embedded in the concrete base body. A reinforcement component is provided that has a plate embedded in the concrete base body at a side of the anchor rail which is facing toward the end face of the concrete base body. The reinforcement component has two anchors fixedly connected to the plate, wherein the two anchors extend away from the plate to a side of the anchor rail which is facing away from the plate. The two anchors each have an end facing away from the plate, wherein the end has an anchoring section, wherein the anchoring section forms an undercut in a direction toward the plate.
