Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing paver edgings require multiple types and frequent reshaping or removal for installation along irregular boundaries, complicating the process and increasing material usage and installation time.

Innovation Solution

A paver edging with elongated strips and extensions that can be bent and reshaped in place, featuring a strap member for stability and a bore for stake fixation, allowing for flexible installation without removal, and concealed by a layer of soil or plants for anchoring.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If rigid edgings are used to define straight boundaries, then structural strength is improved, but adaptability to curved or irregular boundaries deteriorates

Engineering Contradiction:

Improvestructural strengthVSAvoidadaptability to curved boundaries

Core Design Contradiction:

StrengthVSAdaptability or versatility

Solution Approach 1:

The edging is divided into multiple segments or sections that can be connected to each other. Each segment can be independently positioned and secured, allowing the overall edging structure to adapt to curved or irregular boundaries while maintaining structural integrity through the connection of individual strong segments.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The edging incorporates flexible elements or joints that allow it to bend and adapt to curved boundaries. The edging transitions from a completely rigid structure to one with dynamic flexibility, enabling it to conform to various boundary shapes while still providing sufficient structural strength when secured at multiple points.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If flexible edgings are used to conform to curved boundaries, then adaptability is improved, but structural strength deteriorates

Engineering Contradiction:

Improveadaptability to curved boundariesVSAvoidstructural strength

Core Design Contradiction:

Adaptability or versatilityVSStrength

Solution Approach 1:

The flexible edging is segmented into multiple sections that can be independently secured to the ground. This segmentation allows each segment to maintain flexibility for conforming to curved boundaries while providing multiple anchor points that collectively enhance the overall structural strength and stability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The edging is designed with pre-included securing mechanisms such as spikes, anchors, or attachment points that are prepared in advance. These preliminary securing features allow the flexible edging to be rapidly anchored down without requiring complex assembly operations, thereby maintaining both flexibility and strength.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If edging is cut and reshaped multiple times to fit boundaries, then adaptability is improved, but installation time and complexity increase

Engineering Contradiction:

Improveconformity to boundary shapeVSAvoidinstallation time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The edging is supplied as a modular set of pre-cut segments that can be easily connected together. This segmentation eliminates the need for extensive cutting and reshaping operations, as the segments can be quickly assembled along the boundary and secured in place, significantly reducing installation time while maintaining adaptability to various boundary shapes.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The edging incorporates flexible joints or connection mechanisms that allow for quick adjustment and positioning during installation. This dynamic flexibility enables the edging to be rapidly adapted to boundary shapes without requiring multiple cycles of cutting and reshaping, thereby reducing installation time while maintaining conformity to the desired boundary shape.

Inventive Principle:

Principle #15Dynamics

4Adaptability or versatility

If multiple types of edgings are used for different boundary sections, then adaptability to various boundary shapes is improved, but device complexity increases

Engineering Contradiction:

Improveability to edge different boundary typesVSAvoidnumber of edging types

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The edging is designed as a universal product that can be used for both straight and curved boundaries. It incorporates flexible elements, modular segments, and adjustable securing mechanisms that enable a single edging type to adapt to various boundary shapes and conditions, thereby eliminating the need for multiple specialized edging types and reducing overall device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A paver or landscape edging is provided with enhanced anchoring means. The edging has an elongated, longitudinal strip with a paver-facing surface and an opposed surface, and extensions extending from the opposed surface of the elongated strip, each comprising a first wall edge and a bore for receiving a fastener such as a spike or stake. A strap member extends between neighboring extensions, offset from the first wall edge and defining a gap, or anchoring region, when the edging is placed on a substrate. The installed edging may be anchored by fasteners, and by root systems of a concealing layer placed over the edging that grow around the strap member. In addition, a method for installing pavers provides for the fixing of a portion of the edging on the substrate prior to cutting a strap to allow the edging to be deformed in conformance with a curved or irregular boundary.
