Solution Overview

Problem

Existing nautical vehicle steering systems require frequent viewpoint changes and manual operation of controls, leading to increased risk of incorrect maneuvers and necessitate large, complex dashboards with numerous cables, which is inconvenient and space-inefficient.

Innovation Solution

A compact steering control system featuring a rotatable hub that supports control elements and displays, allowing easy access and visibility during operation, reducing the need for dashboard-mounted controls and minimizing cable usage by integrating them into the hub.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If control elements are positioned on the dashboard, then they are easily accessible, but the dashboard becomes large and complex requiring numerous cables

Engineering Contradiction:
Improveaccessibility of control elementsVSAvoiddashboard size and cable quantity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent integrates control elements directly into the steering wheel assembly, merging the steering function with control functions. This eliminates the need for separate dashboard-mounted controls and reduces cable requirements by consolidating connections through the steering column.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The steering wheel is transformed into a multi-functional control interface that combines directional steering with operation of various vehicle controls. This universal design allows the steering wheel to serve both steering and control purposes, reducing the need for additional dashboard components.

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

2Stability of the object's composition

If control elements are fixed on the dashboard, then they are stable, but the skipper must change viewpoint and release the steering wheel to operate them

Engineering Contradiction:
Improvefixed position of control elementsVSAvoidoperational safety and continuity
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The control elements are positioned on the rotatable steering wheel, making them dynamic relative to the driver's viewpoint. As the steering wheel rotates, the controls move with it, maintaining constant accessibility without requiring the driver to shift position or release the wheel.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The steering wheel acts as an intermediary carrier that brings control elements within the driver's natural field of view and reach. This intermediate positioning allows simultaneous steering and control operation without compromising safety or requiring viewpoint changes.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If a large dashboard is used to accommodate all controls, then all controls can be accessed, but the space is not easily used for other functions

Engineering Contradiction:
Improvecontrol accessibilityVSAvoiddashboard area
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

By merging control functions into the steering wheel assembly, the dashboard area is freed up for other purposes. The controls that would traditionally occupy significant dashboard space are now integrated into the steering column, allowing more flexible use of dashboard real estate.

Inventive Principle:
Principle #5Merging (Combining)
