Solution Overview

Problem

The installation of well foundations is challenging due to the difficulty in ensuring correct orientation, which can lead to misalignment of wells, making the process time-consuming and labor-intensive.

Innovation Solution

A well insert with an adjustable channel is provided to correct misalignment after the foundation is installed, allowing the channel to be adjusted relative to vertical and the foundation's axis, ensuring proper orientation of the well.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the well foundation is installed first without correction capability, then the foundation installation process is simpler, but the well orientation cannot be corrected if misalignment occurs

Engineering Contradiction:
Improvewell orientation accuracyVSAvoidfoundation structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The well foundation system is divided into two independent components: the foundation structure and the well insert. The well insert is a separate element that can be adjusted independently within the foundation channel, allowing orientation correction without modifying the foundation itself. This segmentation enables the foundation to remain simple while the insert provides the correction capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The well insert acts as an intermediary element between the foundation and the well. It receives the well and provides the necessary orientation adjustment, mediating between the fixed foundation structure and the required well alignment. This intermediary component isolates the complexity of orientation correction from the foundation design.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Manufacturing precision

If the well foundation requires precise orientation during installation, then the well orientation accuracy is improved, but the installation time and labor requirements increase

Engineering Contradiction:
Improvefoundation orientationVSAvoidinstallation time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The well insert is pre-configured with adjustment capabilities before installation. By preparing the insert in advance with its orientation correction mechanism, the actual installation process becomes faster as the insert can be quickly adjusted to correct any foundation misalignment without requiring time-consuming foundation repositioning.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The well insert incorporates dynamic adjustment mechanisms that allow the channel orientation to be modified after foundation installation. This dynamic capability enables quick corrections to well orientation without requiring the foundation itself to be repositioned, significantly reducing installation time while maintaining precision.

Inventive Principle:
Principle #15Dynamics

3Ease of manufacture

If the well insert has fixed channel orientation, then the insert structure is simpler, but the ability to correct foundation misalignment is lost

Engineering Contradiction:
Improveinsert structureVSAvoidorientation correction capability
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The well insert incorporates dynamic adjustment mechanisms that allow the channel orientation to be modified after insertion into the foundation. The channel can be adjusted to various angles relative to the foundation axis, enabling correction of foundation misalignment while maintaining a relatively simple insert structure that can be manufactured with standard components.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The well insert provides orientation correction by introducing angular adjustment in a different dimensional space. Instead of requiring complex three-dimensional repositioning of the entire insert, the mechanism allows angular adjustment of the channel orientation around the insert axis, correcting foundation misalignment through rotational adjustment rather than positional reconfiguration.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
