Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current fastening methods for concrete cloth and landscape erosion control applications are labor-intensive, costly, and result in protruding fasteners, lacking adaptability and economic feasibility.

Innovation Solution

A drill-adapted tie fastener with a small anvil head and arrow tip blade, combined with a washer that becomes flush with the ground after use, allowing for efficient and cost-effective fastening of concrete cloth, landscape stabilizer sheets, and timbers without protruding fasteners.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional mechanical fasteners (staples, nails, screws) are used to fasten concrete cloth, then the cloth can be secured in place, but the installation becomes labor-intensive and time-consuming

Engineering Contradiction:

Improveinstallation speedVSAvoidlabor intensity

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The patent replaces manual mechanical fastening methods (pounding staples and nails, using power screw drivers) with a drill-mounted fastening system that uses rotational drilling force to install fasteners, significantly reducing labor intensity and increasing installation speed

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a drill adapter as an intermediary device that connects the drill to the fastener, enabling the drill to effectively install the specific fastener design while maintaining control and precision during installation

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If stakes are inserted into ground surfaces to fasten concrete cloth, then the cloth can be secured, but each stake must be separately mounted which is labor and material intensive

Engineering Contradiction:

Improveinstallation efficiencyVSAvoidmaterial consumption

Core Design Contradiction:

ProductivityVSQuantity of substance

Solution Approach 1:

The patent combines multiple functions into a single fastener design that integrates the anchoring function, the fastening function, and the flush surface function, eliminating the need for separate stakes and reducing material consumption

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The fastener serves multiple functions: it anchors into the ground, fastens the concrete cloth, and provides a flush surface, making it a universal solution that replaces multiple different fastening components

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of operation

If conventional fasteners are used to secure concrete cloth, then the cloth can be fastened, but the fasteners protrude upward from the cloth which is undesirable

Engineering Contradiction:

Improveaesthetic appearanceVSAvoidinstallation simplicity

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The fastener is designed with different local qualities: the lower portion is shaped for ground anchoring while the upper portion is designed to be flush with the cloth surface, providing both secure fastening and aesthetic appearance in different locations of the same component

Inventive Principle:

Principle #3Local quality

4Productivity

If screws are fastened using a power screw driver, then fastening can be achieved, but the screw heads are difficult to mount especially when large numbers are needed

Engineering Contradiction:

Improvefastening capacityVSAvoidmounting difficulty

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The patent replaces the screw threading mechanism with a drill-mounted fastening system that uses rotational drilling force, eliminating the difficulty of mounting screw heads while maintaining high fastening capacity

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
