Solution Overview

Problem

Conventional methods for constructing walkways and similar structures are labor-intensive and wasteful, with existing forms being inflexible, costly, and difficult to use, leading to challenges in achieving accurate leveling and uniform depth of particulate and finished paving materials.

Innovation Solution

A form assembly with elongated sections, connector elements, and anchor mounting elements that allows for easy adjustment and scalability, featuring a unique thickness distribution to support screeding equipment and accommodate curved surfaces, made from lightweight, reusable materials like plastic, and a screed system for accurate leveling and compaction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional forms (wood, metal, plastic) are used to contain substrate material and provide leveling reference, then the forms can be inserted and manipulated in the trench, but the forms are heavy, costly, troublesome to assemble, and relatively inflexible

Engineering Contradiction:

Improveflexibility of formsVSAvoidassembly complexity of forms

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The form system is divided into modular form sections that can be easily connected and disconnected. Each form section includes integrated anchor mounting elements, allowing the forms to be assembled and disassembled quickly without complex fastening procedures. This segmentation enables workers to efficiently configure forms for different trench widths and lengths while maintaining flexibility.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The anchor mounting elements are integrated directly into the form sections, combining the form structure and anchoring system into a single unit. This eliminates the need for separate anchoring components and simplifies the overall assembly process, reducing both device complexity and installation time while maintaining adaptability.

Inventive Principle:

Principle #5Merging (Combining)

2Reliability

If forms are anchored using separate devices (stakes, rebar, clips, nails, spacers), then the forms can be secured in place, but the anchoring process becomes troublesome and time-consuming

Engineering Contradiction:

Improvesecuring of forms in placeVSAvoidease of anchoring forms

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The form sections include self-contained anchor mounting elements that enable workers to secure the forms directly without requiring additional anchoring tools or components. The forms are designed to be self-sufficient, with built-in capabilities for straightforward installation and securing.

Inventive Principle:

Principle #25Self-service

3Ease of operation

If the trench width is significantly larger than the finished walkway width to accommodate forms, then the forms can be inserted and manipulated, but this creates wasteful over-digging

Engineering Contradiction:

Improvemanipulation of formsVSAvoidexcavated material waste

Core Design Contradiction:

Ease of operationVSLoss of substance

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

4Ease of operation

If wooden forms are used, then the forms can be easily manipulated, but they warp undesirably and are not reusable

Engineering Contradiction:

Improveease of manipulationVSAvoiddimensional stability of forms

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

The form sections are constructed from plastic material that maintains dimensional stability while remaining easy to manipulate. The plastic material resists warping and deformation under various environmental conditions, ensuring consistent form geometry throughout the installation process and enabling repeated use without degradation of structural integrity.

Inventive Principle:

Principle #35Parameter changes

5Strength

If metal forms are used, then the forms are sturdy and can contain heavy materials, but they are heavy, costly to replace, and troublesome to assemble

Engineering Contradiction:

Improvestrength to contain heavy materialsVSAvoidweight of forms

Core Design Contradiction:

StrengthVSWeight of moving object

AI summary

A form assembly for installation of paving materials has elongated form sections, each having a first side wall facing the paving material and an opposite second side wall that has a first longitudinal channel defined between brackets. A number of connector elements join adjacent elongated form sections. Anchor mounting elements have a first coupling member configured to fit into the first longitudinal channel of the form section and a second coupling member configured for coupling to a mounting anchor. Each of the elongated form sections has an upper screed contact surface orthogonal to the first side wall and wherein a first wall thickness between first and second side walls that is between the upper screed contact surface and the first longitudinal channel exceeds a second wall thickness of the form section that is between the first longitudinal channel and a base that is opposite the upper screed contact surface.
