Solution Overview

Problem

Homeowners face challenges in creating aesthetically pleasing and durable edging for landscaping beds due to the limitations of DIY edging materials and the high cost and complexity of professional curbing solutions.

Innovation Solution

A specialized curb forming tool made of rigid materials, such as plastic, metal, or fiberglass, which allows for the creation of custom concrete curbing of any shape and length without requiring complicated equipment or specialized expertise, using a process involving a curved sheet with a handle and a cement mixture that can be easily packed and smoothed into place.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If professional curbing equipment and methods are used, then the quality and appearance of curbing is improved, but the cost and complexity of installation increase significantly

Engineering Contradiction:
Improvecurbing qualityVSAvoidequipment complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent creates a simplified copy of professional curbing equipment by using a basic forming tool that replicates the essential function of complex professional machinery. The tool copies the curbing formation process without requiring expensive equipment, allowing homeowners to achieve professional-quality results through a simplified apparatus that mimics the core functionality of professional curbing machines.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent employs inexpensive, simple materials for the forming tool that can be easily replaced or discarded. The tool is made from basic materials rather than durable, expensive professional equipment, emphasizing affordability and simplicity over long-term durability and complexity.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

2Manufacturing precision

If professional curbing services are hired, then the appearance and durability of curbing is improved, but the cost increases to over $16 per linear foot

Engineering Contradiction:
Improvecurbing appearanceVSAvoidinstallation cost
Core Design Contradiction:
Manufacturing precisionVSQuantity of substance

Solution Approach 1:

The patent enables homeowners to perform curbing installation themselves using a simple tool, eliminating the need to hire expensive professional contractors. The self-service approach allows individuals to create professional-looking curbing without paying labor costs, significantly reducing the overall expense while maintaining aesthetic quality.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent uses inexpensive materials and a simple tool rather than expensive professional equipment and services, dramatically reducing the cost per linear foot while still achieving acceptable curbing appearance and functionality.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Quantity of substance

If DIY edging materials like bricks or wooden pegs are used, then the cost is reduced, but the appearance becomes square, choppy, or flimsy

Engineering Contradiction:
Improveinstallation costVSAvoidcurbing appearance
Core Design Contradiction:
Quantity of substanceVSManufacturing precision

Solution Approach 1:

The patent copies the smooth, professional appearance of contractor-installed curbing by using a forming tool that shapes concrete into sleek, continuous edges. This eliminates the square, choppy look of brick or wooden edging while maintaining the affordability of DIY installation.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent uses concrete as a composite material that can be molded into smooth, attractive shapes, combining the affordability of DIY materials with the aesthetic quality of professional installations. The concrete mixture allows for smooth finishing that superior to traditional edging materials.

Inventive Principle:
Principle #40Composite materials

4Device complexity

If simple DIY edging is installed, then the cost and complexity are reduced, but the durability and attractiveness of the edging deteriorate

Engineering Contradiction:
Improveinstallation simplicityVSAvoidedging durability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent maintains installation simplicity for DIY homeowners while dramatically improving durability by using concrete that can be molded into strong, lasting curbing. The self-service approach remains accessible but produces much more durable results than traditional edging materials.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent uses concrete as a durable composite material that provides long-lasting, attractive edging compared to flimsy wooden pegs or bricks. The concrete mixture, when properly formed and cured, creates strong, weather-resistant curbing that maintains its appearance and structural integrity over time.

Inventive Principle:
Principle #40Composite materials
