Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing shear reinforcement elements in reinforced concrete base plates are inefficient in transferring tensile forces due to the lack of connection between individual tension rods, leading to undefined positioning and inadequate anchoring, resulting in notch stresses and potential fractures at support points.

Innovation Solution

The shear reinforcement element consists of an upper anchoring plate with openings for the widened heads of tension rods and foot sockets that extend below the lower reinforcement, allowing multiple tension rods to be connected and anchored within the upper reinforcement, ensuring a stable and coherent load transfer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If singular tension rods are used without connection means, then the structure is simple, but the tensile force transmission is inefficient and positioning is undefined

Engineering Contradiction:

Improvestructure simplicityVSAvoidtensile force transmission efficiency

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

Multiple individual tension rods are merged into a unified shear reinforcement element through connecting means, forming an integrated structure that provides both mechanical connection and defined positioning within the concrete base plate

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

Connecting means act as intermediary components that join the tension rods together, enabling effective force transmission between the rods and providing a stable framework for anchoring in the concrete

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If tension rods are arranged freely between reinforcements, then installation is easy, but anchoring is inadequate and notch stresses occur

Engineering Contradiction:

Improveinstallation easeVSAvoidanchoring adequacy

Core Design Contradiction:

Ease of operationVSStrength

Solution Approach 1:

The tension rods are pre-assembled into a connected structure before installation, ensuring proper geometric arrangement and structural integrity prior to placement in the concrete base plate

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The connecting means merge the tension rods into a unified element that can be installed as a single unit while providing distributed anchoring points that eliminate notch stresses

Inventive Principle:

Principle #5Merging (Combining)

3Force

If multiple tension rods are used without mutual connection, then force distribution is improved, but structural coherence is lost

Engineering Contradiction:

Improveforce distributionVSAvoidstructural coherence

Core Design Contradiction:

ForceVSStability of the object's composition

Solution Approach 1:

The connecting means merge multiple tension rods into a coherent structural unit that maintains both force distribution capabilities and structural integrity as a unified element

Inventive Principle:

Principle #5Merging (Combining)

AI summary

The shear reinforcement element (12) has an upper anchoring sheet, in which enlarged heads of tension rods (16) are incorporated in a load transferring manner. The lower side of the shear reinforcement element is made of multiple foot sockets, in which the enlarged lower heads of tension rods are incorporated. The botttom surfaces of the foot sockets of the tension rods extend below a lower reinforcement. The foot sockets consists of a high strength concrete, in which the lower head of the tension rods is infused. The foot sockets consist of socket elements formed of metal or plastic. An independent claim is included for a support plate with a covering.
