Solution Overview

Problem

Existing building structures lack the ability to effectively check and replace foundations without removing the base element from the ground, posing a risk to structural integrity and stability over time due to material degradation and changes in soil conditions.

Innovation Solution

A building element with primary screw foundations that can be inserted and replaced without removing the base member from the ground, equipped with sensors and signal sources for monitoring stability and integrity, allowing for periodic inspection and replacement of both primary and secondary screw foundations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional concrete foundations or piles are used, then the structure achieves initial stability and load-bearing capacity, but the foundations cannot be checked or replaced without removing the base element from the ground

Engineering Contradiction:
Improvefoundation integrityVSAvoidfoundation inspection accessibility
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The foundation system is segmented into replaceable screw foundations that can be independently accessed through openings in the base element. This allows individual foundation inspection and replacement without removing the entire base element, resolving the contradiction between maintaining structural integrity and enabling foundation accessibility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Openings in the base element serve as intermediaries that provide access to the foundations. These openings allow inspection tools and replacement components to reach the foundations while the base element remains in place, enabling foundation maintenance without complete structure removal.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Duration of action of stationary object

If foundations are permanently embedded in the ground, then the structure achieves long-term stability, but material degradation and soil changes cannot be addressed

Engineering Contradiction:
Improvestructure service lifeVSAvoidfoundation replacement capability
Core Design Contradiction:
Duration of action of stationary objectVSAdaptability or versatility

Solution Approach 1:

The foundation system transitions from a static, permanent embedding to a dynamic, replaceable configuration. Screw foundations can be removed and reinstalled, allowing the structure to adapt to material degradation or soil changes over time, thus extending service life through periodic maintenance.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The screw foundations can be discarded (removed) and recovered (reinstalled or replaced) when degradation occurs. This allows continuation of structure service life by replacing degraded foundations rather than removing the entire structure.

Inventive Principle:
Principle #34Discarding and recovering

3Ease of manufacture

If screw foundations are used, then immediate load-bearing capacity and ease of installation are achieved, but the ability to monitor foundation condition over time is limited

Engineering Contradiction:
Improveinstallation simplicityVSAvoidfoundation condition monitoring
Core Design Contradiction:
Ease of manufactureVSMeasurement precision

Solution Approach 1:

Sensors are integrated into the screw foundations to provide continuous feedback on foundation condition, including load, movement, and integrity. This monitoring capability complements the easy installation of screw foundations by enabling ongoing assessment of their performance and condition.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The screw foundations serve multiple functions: providing immediate load-bearing capacity, enabling easy installation, and housing sensors for condition monitoring. This multi-functionality resolves the contradiction between installation simplicity and monitoring capability.

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