Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing corner shuttering elements face issues with edge strip orientation and reinforcement, particularly under concrete pressure, due to complex bolt element structures and limited positioning options, leading to potential indentation and deformation in concreted shafts.

Innovation Solution

The corner shuttering element features bolt elements attached to extraction struts of edge strips, allowing for improved orientation and reinforcement, especially at the bottom where concrete pressure is highest, with adjustable clamping jaws and U-shaped bolt designs for stability and ease of assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If bolt elements are attached to reinforcing ribs, then edge strips can be fixed in position, but bolt elements cannot be optimally positioned in the lower region where no ribs are provided

Engineering Contradiction:

Improveedge strip orientationVSAvoidpositioning flexibility

Core Design Contradiction:

Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The patent applies this principle by making the bolt elements universally applicable to multiple attachment locations. Instead of being restricted to reinforcing ribs only, the bolt elements can now be attached to both reinforcing ribs and transverse stiffening elements, allowing optimal positioning anywhere along the limb according to concrete pressure requirements

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of manufacture

If bolt elements are restricted to reinforcing rib regions, then assembly is simplified, but optimal positioning in high-load lower regions is prevented

Engineering Contradiction:

Improveassembly simplicityVSAvoidconcrete pressure resistance

Core Design Contradiction:

Ease of manufactureVSStrength

Solution Approach 1:

The patent applies this principle by dividing the attachment system into two types of attachment points: reinforcing ribs and transverse stiffening elements. This segmentation allows bolt elements to be distributed optimally throughout the limb structure, with multiple attachment locations available to handle varying concrete pressure loads at different heights

Inventive Principle:

Principle #1Segmentation

3Reliability

If complex bolt element structures are used, then edge strip fixation is improved, but assembly complexity and difficulty increase

Engineering Contradiction:

Improveedge strip positioning stabilityVSAvoidbolt element structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies this principle by using simple, easily replaceable bolt elements with basic components (bolt body, threading, head). These straightforward designs are easy to manufacture and assemble, providing reliable edge strip fixation without requiring complex mechanisms, and can be quickly replaced if needed

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

AI summary

A corner shuttering element with two limbs arranged at an angle to each other, on the outer edge of which limbs, edge strips are arranged that can be retracted and extended by means of articulated levers, wherein the edge strips can each be aligned and fixed in their position by means of a plurality of locking elements arranged distributed over the height of the corner shuttering element, and wherein the locking elements are arranged on guides for pull-out webs of the edge strips.
