Solution Overview

Problem

Existing mechanical systems fail to automatically align a Floating Platform Axial Center Line (FPACL) with changing water flow directions in the ocean, leading to inefficient balancing and orientation.

Innovation Solution

A directional floating platform system with four symmetrically installed wings, each equipped with windows that open or close based on water flow direction, generating torque to rotate the FPACL and maintain alignment with the water flow.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If traditional mechanical alignment systems are used, then the structure is simple, but the system cannot automatically align with changing water flow directions

Engineering Contradiction:
Improveautomatic alignment capabilityVSAvoidsystem structure complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The system uses self-service through passive hydrodynamic mechanisms. The windows automatically open or close based on water flow direction without external control, and the wings generate torque automatically to realign the platform. This eliminates the need for active sensors, motors, or control systems while achieving automatic alignment.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system employs asymmetric window configurations on different wings. When water flow direction changes, the asymmetric opening/closing patterns of windows on various wings create unbalanced hydrodynamic forces that generate corrective torque, enabling automatic realignment without complex control mechanisms.

Inventive Principle:
Principle #4Asymmetry

2Measurement precision

If the windows are designed to open in one direction only, then the alignment precision is improved, but the system cannot respond to bidirectional flow changes

Engineering Contradiction:
Improvealignment precisionVSAvoidresponse to flow direction changes
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The system divides the platform into four separate wings with independently controllable windows. Each wing can respond to flow direction changes independently, allowing the system to handle bidirectional and multi-directional flow changes while maintaining precise alignment through coordinated window operations across all wings.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system inverts the traditional approach by using window opening/closing states to generate alignment forces rather than using active actuators. The passive hydrodynamic pressure differential created by asymmetric window configurations automatically generates torque in the correct direction to realign the platform.

Inventive Principle:
Principle #13The other way round (Inversion)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The system effectively aligns the FPACL with the water flow direction, ensuring balanced water pressure distribution and maintaining orientation even as the flow direction changes, preventing rotation misalignment.

Implementation Method 1

If the water flows in one direction, then the windows will be opened by the push of the water mass flow. But, if water flows in the opposite direction, the windows are not allowed to be opened.

Methodology Applied
Scientific EffectHydrodynamic pressure: Pressure Increase

Implementation Method 2

the set of four wings generates a torque that rotates the FPACL until the FPACL is aligned with the direction in which the water mass flows

Methodology Applied
Scientific EffectTorque generation: Torque

Implementation Method 3

the windows in the front two wings will be opened and the windows in the two rear wings will be closed and evenly distributed water pressure on the set of the two rear wings balances the Floating Platform (FP) with respect to the water flowing direction

Methodology Applied
Scientific EffectPressure distribution: Pressure Increase
