Solution Overview

Problem

Existing anchoring piles fail to maintain stability in various soil types, including rocky, stony, and loose earth, and are not easily reusable due to unlocked anchors and lack of effective deployment mechanisms.

Innovation Solution

A hollow body anchoring pile with integral anchoring members and a sliding rod system, featuring a spacer member and thrust means that initiate and maintain anchoring by deploying the members into the ground, allowing for secure anchoring and easy dismantling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a hollow body anchoring pile with sliding rod and thrust means is used, then anchoring reliability in diverse soil types is improved, but device complexity increases

Engineering Contradiction:
Improveanchoring reliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The anchoring pile is divided into distinct functional components: a hollow body for structural support, a sliding rod for actuation, thrust means for initiating deployment, and multiple anchoring members for securing. This segmentation allows each component to be optimized for its specific function while maintaining overall system reliability across diverse soil conditions.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The anchoring system transitions from a static configuration to a dynamic one through the sliding rod mechanism. The rod can move along the hollow body to transform the anchoring members from a retracted state to a deployed state, enabling the system to adapt to different soil types and anchoring requirements while maintaining manageable complexity through controlled movement.

Inventive Principle:
Principle #15Dynamics

2Strength

If anchoring members are deployed into the ground, then anchoring strength is improved, but ease of operation deteriorates

Engineering Contradiction:
Improveanchoring strengthVSAvoidease of operation
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The thrust means automatically engage with the anchoring members to initiate their deployment into the ground when the sliding rod moves. This self-service mechanism eliminates the need for complex external actuation systems, allowing strong anchoring to be achieved through simple operation of the sliding rod while maintaining ease of operation.

Inventive Principle:
Principle #25Self-service

3Manufacturing precision

If the pile structure is made integral with anchoring members, then manufacturing precision is improved, but ease of repair worsens

Engineering Contradiction:
Improvemanufacturing precisionVSAvoidease of repair
Core Design Contradiction:
Manufacturing precisionVSEase of repair

Solution Approach 1:

While the anchoring members are integral with the hollow body for manufacturing precision, the sliding rod and thrust means are designed as separate, interchangeable components. This segmentation allows for easy replacement of wear-prone parts like the thrust means without replacing the entire pile structure, balancing manufacturing precision with ease of repair.

Inventive Principle:
Principle #1Segmentation

4Reliability

If multiple anchoring members are used, then anchoring reliability is improved, but device complexity increases

Engineering Contradiction:
Improveanchoring reliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Multiple anchoring members are designed with identical or similar structures that perform the same function of securing the pile to the ground. This universality allows for increased reliability through redundancy while minimizing the increase in device complexity, as each member is a standardized component that can be manufactured and deployed systematically.

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