Solution Overview

Problem

In smart mobility vehicles, the fixed position of the steering wheel and occupant seating can obstruct the view of information displays, and adjusting the steering wheel to accommodate different occupants is limited, affecting driving convenience and safety.

Innovation Solution

A steering apparatus with a cockpit module and a switchable steering wheel that can move between the driver and passenger seats, featuring a locking mechanism to restrict rotation and a portable terminal holding space for vehicle control applications, along with an occupant recognition-based image display control system that adjusts the image display area to avoid obstructing the occupant's view.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the steering wheel is fixed in position, then the structure is simple and stable, but it blocks the occupant's view of information displays and cannot adapt to different occupants

Engineering Contradiction:
Improveadaptability to different occupantsVSAvoidsteering wheel structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The steering wheel is designed to be movable between different positions (driver seat and passenger seat) rather than fixed. The base plate can slide along the rail bracket in the longitudinal direction, and the steering wheel can be locked at different positions using the locking part with locking protrusions and locking grooves, enabling adaptation to different occupants while maintaining structural simplicity

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The steering wheel is designed to serve multiple functions: it can be positioned for both driver and passenger seats, includes a portable terminal holding space for device placement, and integrates vehicle control applications. This multi-functionality allows a single steering wheel structure to adapt to different usage scenarios and occupants

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

2Adaptability or versatility

If the steering wheel is adjusted in top-to-bottom direction, then it can accommodate different occupant heights, but it has limited adjustment range within a fixed cockpit

Engineering Contradiction:
Improveadjustment rangeVSAvoiddriving convenience
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The steering wheel adjustment is extended from the traditional single vertical dimension to include longitudinal movement along the vehicle's length. The base plate slides along the rail bracket in the longitudinal direction, adding a new dimension of adjustability that allows the steering wheel to reach both driver and passenger seats, significantly expanding the adjustment range beyond what vertical adjustment alone could achieve

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

3Adaptability or versatility

If the steering wheel position is switched between driver and passenger seats, then it can accommodate different occupants, but the steering wheel may rotate during switching affecting safety

Engineering Contradiction:
Improveposition switching capabilityVSAvoidsteering wheel stability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The locking part with locking protrusions and locking grooves is designed to engage before the steering wheel position switching is completed. This preliminary locking action prevents the steering wheel from rotating during the position switching process, ensuring stability and safety while maintaining the ability to switch between driver and passenger seat positions

Inventive Principle:
Principle #10Preliminary action

4Ease of operation

If information display is positioned at fixed location, then the display structure is simple, but it obstructs the occupant's view depending on build and position

Engineering Contradiction:
Improveoccupant view clarityVSAvoiddisplay control system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The vehicle control system uses the portable terminal to receive and process occupant information, then automatically adjusts the image display area position based on this feedback. This feedback mechanism ensures that the display does not obstruct the occupant's view while maintaining a relatively simple display structure by only adjusting the display area position rather than the entire display system

Inventive Principle:
Principle #23Feedback

AI summary

A steering apparatus of a smart mobility vehicle (10) includes: a cockpit module (220, 310) disposed in front of a driver seat and a passenger seat within a vehicle (10); a steering wheel (230, 324) part connected to the cockpit module (220, 310), and switchable between a position toward the driver seat and a position toward the passenger seat in a longitudinal direction of the cockpit module (220, 310); and a locking part to fix the steering part according to a preset condition. The cockpit module (220, 310) includes a first flat section (311) disposed in front of the driver seat and a second flat section (311) disposed in front of the passenger seat; and a locking section (311B, 311) curved upward to connect the first flat section (311) and the second flat section (311).
