Rotating Shaft Gesture Display for Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices for vehicles lack the ability to selectively and remotely display a variety of different gestures or objects in a visually engaging manner, failing to provide the same level of excitement and interaction as desired by users.
Innovation Solution
A switching gesture display device with a rotatable shaft and solenoid mechanism that allows for the alternation between primary and secondary indicia displays, powered by the vehicle's electrical system and controlled by a switch, enabling dynamic display of different hand signals or objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single static display is used, then the device is simple and easy to manufacture, but it lacks versatility and user engagement
Solution Approach 1:
The patent applies the dynamics principle by implementing a rotatable shaft mechanism that allows the display to switch between multiple static positions, each showing different hand gestures or objects. This transforms a single static display into a dynamic multi-position display, providing versatility without requiring a completely complex moving display system.
Solution Approach 2:
The display is segmented into multiple discrete positions or faces, each showing a different gesture or object. The rotatable shaft divides the display into separate selectable states, allowing the system to offer variety by presenting one segment at a time rather than requiring all segments to be visible simultaneously.
2Ease of operation
If remote control capability is added, then user interaction is improved, but device complexity increases
Solution Approach 1:
A control switch serves as an intermediary between the user and the shaft rotation mechanism. This simple switch mediates the interaction by converting user input into mechanical rotation of the shaft, providing remote control capability without requiring complex electronic control systems.
3Adaptability or versatility
If multiple displays are mounted on the shaft, then versatility is improved, but manufacturing complexity increases
Solution Approach 1:
Multiple display faces are merged onto a single rotatable shaft structure. Instead of manufacturing separate devices for each gesture, the patent combines multiple displays on one shaft, allowing all gestures to be housed in a single unit that can be manufactured and assembled as one integrated component.
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
Enhances user engagement and interaction by allowing controlled rotation of displays, offering greater versatility and entertainment value compared to traditional window decals and stickers, with easy mounting and removal options for specific situations.
Implementation Method 1
A shaft rotation device such as a solenoid is mounted within the main box and operatively connected with the shaft for controlled rotation thereof

AI summary
A switching gesture display device for vehicles includes a main box and a shaft rotatably mounted in the main box with opposite ends extending through and outside the main box, the shaft being rotatable between an initial position and a rotated position. Two primary indicia displays are mounted on the opposite ends of the shaft, the two primary indicia displays being displayed in a generally upright position when the shaft is in the initial position, and two secondary indicia displays are mounted on the shaft generally adjacent the two primary indicia displays, the two secondary indicia displays being displayed in a generally upright position when the shaft is in the rotated position. A shaft rotation device rotates the shaft between the initial position and the rotated position to alternatively display the two primary indicia displays in the initial position and the two secondary indicia displays in the rotated position.
