Wheel LED Display Control With GPS-Based Content Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wheel-mounted LED display systems for vehicles have fixed display settings that cannot be changed while the vehicle is moving, rely on batteries that need replacement or recharging, and do not efficiently utilize the center of the wheel for display space, with bespoke designs required for different wheel types.
Innovation Solution
A system comprising an LED display device linked to a computer with GPS, connected via a wireless network to a main server, allowing dynamic display of information packets based on location and time, with wireless communication and rechargeable power solutions, and adaptable attachment to various wheel types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If information is stored on internal memory before installation, then the LED device can operate independently, but the display settings become fixed and cannot be changed while the vehicle is moving
Solution Approach 1:
The system divides the information storage and control functionality into separate components: a main server that stores multiple information packets with location/time associations, a computer that receives location data and determines which packets to display, and the LED display device that simply displays received information. This segmentation allows dynamic content updates without complicating the LED device itself.
Solution Approach 2:
The computer acts as an intermediary between the main server and the LED display device. It receives location information from GPS, queries the main server for appropriate information packets based on current location and time, and then transmits the selected packet to the LED device for display. This intermediary enables dynamic content delivery while keeping the LED device simple.
2Duration of action of moving object
If batteries are used to power the LED device, then the device can operate independently, but the batteries eventually run out and need replacement or recharging
Solution Approach 1:
The system merges the power supply of the LED display device with the vehicle's existing electrical system. Instead of using separate batteries that need replacement, the LED device draws power from the vehicle's battery through the hub assembly, eliminating the need for dedicated power sources and their associated maintenance.
Solution Approach 2:
The hub assembly serves multiple functions: it provides structural support for the wheel, enables braking and acceleration control, and now also serves as the power delivery mechanism to the LED display device. This multi-functionality eliminates the need for separate power management systems.
3Area of stationary object
If the LED device is mounted on the wheel hub, then it can display information on the wheel, but it does not reach the centre of the wheel resulting in wasted display space
Solution Approach 1:
The hub assembly is designed as a universal mounting platform that can accommodate LED display devices of various sizes and configurations. It provides standardized mounting points and power delivery that work across different wheel types, enabling full utilization of display area from center to rim without requiring bespoke designs.
Solution Approach 2:
The system transitions from a limited mounting position to a comprehensive radial arrangement where LED elements can be distributed from the center of the wheel outward to the rim. This dimensional expansion maximizes the usable display area by utilizing the entire radial space of the wheel.
4Adaptability or versatility
If the LED device is mounted on specific wheel types, then it can be installed, but bespoke designs are required for each wheel type reducing adaptability
Solution Approach 1:
The hub assembly is designed as a universal interface that can be integrated with different wheel types and vehicle systems. It provides standardized mounting mechanisms, power delivery protocols, and data communication interfaces that work across various wheel configurations, eliminating the need for bespoke designs for each wheel type.
Solution Approach 2:
The system employs dynamic configuration capabilities where the hub assembly and LED display device can be adapted to different wheel types through software configuration and adjustable mounting parameters. This allows the same hardware platform to serve multiple wheel types without requiring physical redesign.
