Solution Overview

Problem

Existing smartphone mount devices do not effectively integrate with vehicle gear shift knobs to provide a secure and universal mounting solution for smartphones, lacking a mechanism to magnetically engage the device and allow for easy installation on the gear shift shaft.

Innovation Solution

A smartphone mount device comprising a first and second panel that form a gear shift knob, with a magnet integrated into the knob to magnetically engage a smartphone, and a shaft channel to attach to the gear shift shaft, allowing secure and visible mounting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a smartphone mount device is designed to attach to a gear shift lever, then the smartphone can be positioned for driver visibility, but the device lacks a secure attachment mechanism to the gear shift shaft

Engineering Contradiction:

Improvesmartphone positioning for driver visibilityVSAvoidattachment security to gear shift shaft

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent replaces traditional mechanical attachment mechanisms (screws, clips, or adhesive mounts) with a magnetic attachment system. The magnet integrated into the gear shift knob creates a magnetic field that securely holds the smartphone containing a ferromagnetic component, achieving reliable attachment without complex mechanical fastening structures.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the attachment parameter from mechanical interlocking to magnetic attraction. By utilizing magnetic force as the attachment mechanism, the device achieves secure holding capability while maintaining ease of installation and removal, resolving the contradiction between operational ease and attachment reliability.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If a magnet is integrated into the gear shift knob, then the smartphone can be securely held in place, but the device structure becomes more complex

Engineering Contradiction:

Improvesmartphone holding securityVSAvoidgear shift knob structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the magnet directly into the gear shift knob structure during manufacturing. The magnet becomes an integrated component of the knob rather than a separate attachment device, simplifying the overall system architecture while maintaining secure smartphone holding capability through magnetic attraction.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The gear shift knob serves multiple functions: it provides the traditional gear shifting operation and simultaneously acts as a mounting structure for the smartphone via the integrated magnet. This multi-functionality reduces the need for separate mounting devices, thereby reducing overall device complexity while maintaining reliable smartphone attachment.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Illumination intensity

If a gear shift knob structure is used to mount the smartphone, then the smartphone can be positioned for visibility, but the attachment mechanism for the gear shift shaft is insufficient

Engineering Contradiction:

Improvesmartphone visibility to driverVSAvoidattachment to gear shift shaft

Core Design Contradiction:

Illumination intensityVSReliability

Solution Approach 1:

The patent replaces inadequate mechanical attachment methods with a magnetic attachment system. The magnet integrated into the gear shift knob creates a secure magnetic field that reliably attaches to the ferromagnetic component in the smartphone, ensuring both visibility positioning and secure attachment simultaneously.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A gearshift smartphone mount device includes a first panel that is structured to have a stem portion extending downwardly from a knob portion. A second panel is structured to have a stem portion extending downwardly from a knob portion and the second panel is attachable to the first panel such that the first panel and the second panel define a gear shift knob. A shaft channel in the first panel is aligned with a shaft channel in the second panel to defines a hole which insertably receives a gear shift shaft of a vehicle. A magnet is integrated into the first panel and the second panel and the magnet magnetically engages a personal electronic device to facilitate the personal electronic device to be visible to a driver of the vehicle.
