Jog-Shuttle Control Button for Vehicle Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers face inconvenience and safety risks when operating navigation devices in vehicles, as they need to divert their attention from the road to interact with touch-screen controls for map extension and reduction, volume adjustment, and sound control.
Innovation Solution
An electronic device control button with a jog-shuttle mechanism that allows for simple vertical movement to control navigation device functions, including map size adjustment, while maintaining sound control capabilities, using a base part, return spring, and terminal parts to contact different slots on a circuit board for various electrical signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the driver operates the navigation device by directly touching the screen, then the driver can control map extension and reduction, but the driver's eyes are deviated from the road causing safety risks
Solution Approach 1:
The patent introduces a jog-shuttle as an intermediary control device that mediates between the driver and the navigation device. The jog-shuttle translates simple rotational and push operations into complex navigation commands (map extension, reduction, sound control) without requiring the driver to directly touch the screen or look at the display, thus maintaining safety while enabling operation
Solution Approach 2:
The patent replaces the direct touch-screen interface (optical/electronic interaction) with a mechanical jog-shuttle interface. The jog-shuttle uses rotational and linear mechanical movements to generate control signals, substituting the need for visual attention and direct screen contact with tactile mechanical control
2Adaptability or versatility
If the driver operates the navigation device while watching the screen, then the driver can control map functions, but it is inconvenient and unsafe as eyes are deviated from the road
Solution Approach 1:
The jog-shuttle serves as a mediator that provides full navigation control capabilities (map extension, reduction, sound adjustment) through simple rotational and push operations that can be performed without visual attention to the screen, making the device adaptable and versatile while maintaining ease of operation
3Ease of operation
If a jog-shuttle is provided on the center fascia panel, then the driver can control sound functions, but the navigation device requires separate direct screen operation
Solution Approach 1:
The patent enhances the jog-shuttle to perform multiple functions: both sound control (volume adjustment, playback) and navigation device control (map extension, reduction). This multi-functionality consolidates control operations into a single interface, reducing overall system complexity while maintaining ease of operation across different device functions
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
Enables drivers to conveniently and safely operate electronic device functions, such as navigation map size adjustment and sound volume control, without diverting attention from the road, improving operational convenience and safety.
Implementation Method 1
a return spring provided on the center fascia panel, configured to limit movement of the jog-shuttle, and to recover the jog-shuttle to the reference position
