Solution Overview

Problem

Existing ground anchors often tear through matting or damage the ground surface when driven into the ground due to inadequate design, particularly when encountering stony or unstable terrain.

Innovation Solution

A ground anchor design featuring a body with a ground piercing means comprising a first tapering member and multiple transverse tapering members, along with serrated teeth, which allows for stable penetration without tearing matting or damaging the ground, and includes a drive formation for easy installation and a securing formation for stabilizing arrangements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a conventional ground anchor design is used to drive the anchor into the ground, then the anchor can be installed, but the matting is torn and the ground surface is damaged

Engineering Contradiction:
Improveinstallation easeVSAvoidmatting damage and ground surface damage
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The ground piercing means is divided into multiple separate tapering members (first tapering member and plurality of second tapering members) arranged in a radial pattern. This segmentation allows each member to independently penetrate the matting and ground without concentrating all the cutting forces on a single point, thereby preventing matting tear while maintaining effective penetration capability

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The tapering members are specifically designed with tapered edges that concentrate force at the tip for effective penetration, while the overall ground piercing means is arranged to distribute the penetration force across multiple contact points. This local quality differentiation enables effective ground penetration without concentrating damaging forces on the matting

Inventive Principle:
Principle #3Local quality

2Force

If a single large tapering member is used for ground penetration, then penetration force is concentrated, but the matting is torn due to excessive localized stress

Engineering Contradiction:
Improvepenetration force concentrationVSAvoidmatting tear
Core Design Contradiction:
ForceVSObject-affected harmful factors

Solution Approach 1:

The single large tapering member is segmented into multiple smaller tapering members (first tapering member and plurality of second tapering members) arranged radially. Each member provides localized penetration force while the distributed arrangement prevents excessive stress concentration on the matting, resolving the contradiction between needed penetration force and matting protection

Inventive Principle:
Principle #1Segmentation

3Reliability

If multiple tapering members are added to the ground piercing means, then penetration effectiveness is improved, but the device complexity increases

Engineering Contradiction:
Improvepenetration effectivenessVSAvoidground piercing means complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Multiple tapering members are merged into a single integrated ground piercing means assembly that is attached to the ground anchor body. This combining approach maintains the penetration effectiveness of multiple members while reducing overall device complexity compared to using separate independent piercing elements

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The ground piercing means with multiple tapering members serves multiple functions: it penetrates the matting, penetrates the ground (especially effective in stony ground), and provides a stable mounting structure for the ground anchor. This multi-functionality justifies the increased complexity by delivering superior penetration reliability

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A ground anchor (10) comprises a body (12) and a ground piercing means (40) on the body. The ground piercing means comprises a tapering member (42) having opposite edges (48) that taper towards each other from the body. The tapering member may have two opposite faces (50) extending between the opposite edges, the opposite faces being substantially parallel to each other.
