Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional foundation piles lack sufficient strength against lateral external forces, such as wind pressure and vibrations, leading to weakened support and potential deformation under vertical and horizontal loads.

Innovation Solution

The foundation pile design includes a central axis member with a base plate at the upper end and a circumferential member that reinforces the upper side circumference, eliminating the weak neck part between the base plate and the circumferential member. Additionally, multiple reinforcing wings and an intermediate expansion reinforcing plate enhance the pile's strength and durability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the base plate is attached only to one tubular body for forming the central axis, then the structure is simpler, but the neck part between the base plate and circumferential member is weakened due to its small cross-sectional area

Engineering Contradiction:

Improvestructure simplicityVSAvoidneck part strength

Core Design Contradiction:

Device complexityVSStrength

Solution Approach 1:

The patent merges the central axis member and circumferential member into a unified structural system where the circumferential member is positioned adjacent to and integrated with the central axis member. This merging creates a composite support structure that eliminates the weak neck part by providing continuous circumferential reinforcement around the central axis, thereby increasing the effective cross-sectional area without significantly increasing overall structural complexity.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent employs a composite structural configuration where the central axis member (tubular body) and circumferential member work together as a composite system. The circumferential member acts as a reinforcing element that complements the central axis member, creating a composite structure with enhanced strength-to-weight ratio and improved load-bearing capacity compared to a single tubular body.

Inventive Principle:

Principle #40Composite materials

2Ease of manufacture

If the foundation pile uses a simple tubular body configuration, then the manufacturing is easier, but it does not have sufficient strength against external forces in a lateral direction

Engineering Contradiction:

Improvemanufacturing easeVSAvoidlateral direction strength

Core Design Contradiction:

Ease of manufactureVSStrength

Solution Approach 1:

The patent segments the foundation pile into distinct functional components: a central axis member for vertical load bearing and a circumferential member for lateral reinforcement. This segmentation allows each component to be optimized for its specific function while maintaining manufacturing simplicity. The circumferential member can be manufactured separately and then attached to the central axis member, preserving ease of manufacture while achieving enhanced lateral strength.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by concentrating the lateral reinforcement specifically at the circumferential region where it is most needed, rather than uniformly thickening the entire tubular body. The circumferential member provides localized strengthening at the critical upper side circumference area, improving lateral strength without unnecessarily increasing material usage or manufacturing complexity throughout the entire structure.

Inventive Principle:

Principle #3Local quality

3Adaptability or versatility

If the upper end of the foundation pile repeatedly flows in a lateral direction, then the structure can accommodate movement, but the entire foundation pile is pulled on the upper side, weakening the support force

Engineering Contradiction:

Improvemovement accommodationVSAvoidsupport force

Core Design Contradiction:

Adaptability or versatilityVSStrength

Solution Approach 1:

The patent employs a counterbalancing mechanism where the circumferential member acts as a restraining element that counteracts the lateral pulling forces. When the central axis member experiences lateral movement or pulling forces, the circumferential member provides opposing reinforcement that prevents excessive displacement and maintains the foundation pile's vertical alignment, thereby preserving support force while allowing controlled adaptability.

Inventive Principle:

Principle #8Anti-weight (Counterweight)
