Solution Overview

Problem

Existing shift-by-wire electronic transmission systems lack a design that enhances stability through improved visual recognition and marketability through high-tech imagery, particularly in the exposure and concealment of shift operation and design units.

Innovation Solution

A sphere-type shift control apparatus with a shift operation unit on one hemisphere and a design unit for indirect illumination and image transmission on the other hemisphere, configured to rotate 180 degrees to expose either unit based on operational requirements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the shift operation unit is always exposed, then the driver can easily operate the gear shift, but the design unit for indirect illumination and image transmission cannot be displayed

Engineering Contradiction:
Improvegear shift operation accessibilityVSAvoidvisual design functionality
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The spherical mechanism is designed to rotate dynamically between two positions: one where the shift operation unit is exposed for driver operation, and another where the design unit for indirect illumination and image transmission is exposed. This dynamic reconfiguration allows the system to alternate between operational mode and aesthetic/display mode, resolving the contradiction between ease of operation and visual design functionality.

Inventive Principle:
Principle #15Dynamics

2Device complexity

If the design unit is always exposed, then the aesthetic and high-tech imagery is maintained, but the shift operation unit cannot be accessed when needed

Engineering Contradiction:
Improvevisual design and illuminationVSAvoidgear shift accessibility
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The system employs a rotatable spherical mechanism that can be dynamically repositioned. When aesthetic display is prioritized, the design unit faces outward; when gear shifting is required, the mechanism rotates to expose the shift operation unit. This dynamic adaptability resolves the contradiction between maintaining aesthetic appearance and ensuring operational accessibility.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If both units are always visible, then all functionalities are accessible, but the visual recognition stability and high-tech imagery are compromised

Engineering Contradiction:
Improvefunctional accessibilityVSAvoidvisual recognition stability
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The spherical mechanism is segmented into two distinct hemispheres: one dedicated to the shift operation unit and the other to the design unit for indirect illumination and image transmission. This segmentation allows each unit to be independently exposed or concealed, ensuring that only one functional element is visible at a time. This resolves the contradiction by maintaining visual recognition stability through exclusive exposure while preserving full functional versatility through sequential accessibility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The rotatable spherical mechanism enables dynamic switching between exposing the shift operation unit and the design unit. This dynamic reconfiguration ensures that the system maintains stable visual recognition by presenting only one unit at a time, while still providing adaptability and versatility by making both units accessible through rotation.

Inventive Principle:
Principle #15Dynamics

AI summary

A sphere-type shift control apparatus for an electronic transmission system includes a shift operation unit configured to be operated by a driver of a vehicle for gear shifting on a first hemisphere of a spherical mechanism and a design unit for indirect illumination and image transmission on a second hemisphere of the spherical mechanism. By rotating the spherical mechanism, only the shift operation unit is exposed to a vehicle interior through an opening of a housing when a shift operation is required, while only the design unit is exposed to the vehicle interior through the opening of the housing when the shift operation is not required.
