Vehicle Topper Mounting Structure for Vibration-Stable Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roof-mounted vehicle toppers with electronic displays face challenges due to increased weight and size demands, requiring extensive and costly internal structural modifications for secure mounting, and are prone to damage from vibrational forces during vehicle operation.
Innovation Solution
A roof mounting apparatus and system featuring cross bars with varying cross sections and a mounting device that secures the vehicle topper to base units at the vehicle's corners, using threaded fasteners and rivet nuts for a watertight seal, and includes a wiring system to connect the topper to the vehicle's power source and computer system, with components designed to attenuate vibrational forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electronic displays are used to replace traditional static displays, then content can be quickly changed and videos/interactive graphics can be displayed, but the vehicle topper becomes heavier
Solution Approach 1:
The vehicle topper is divided into modular components: a removable topper unit with display, a mounting system with base units and cross bars, and fastening mechanisms. This segmentation allows the heavy electronic display component to be separated from the vehicle structure, enabling easy removal and relocation without permanently modifying the vehicle, thus resolving the contradiction between providing versatile electronic displays and avoiding excessive weight/complexity additions to the vehicle.
2Area of moving object
If larger electronic displays are used to meet market demands, then display size increases, but the vehicle topper requires increasingly larger and heavier structural supports
Solution Approach 1:
The mounting system distributes structural support across multiple dimensions by using four base units positioned at corners of the vehicle roof, connected by cross bars that span the roof width. This dimensional distribution of support structures allows larger displays to be mounted without concentrating excessive weight and structural requirements in a single location, thereby enabling larger display sizes while managing the overall structural weight and complexity.
3Reliability
If enhanced internal structural supports are provided to securely mount heavy electronic displays, then mounting security improves, but installation effort and costs increase significantly
Solution Approach 1:
The base units are pre-installed on the vehicle roof before the topper unit is mounted. These base units include pre-configured mounting interfaces and fastening mechanisms that are prepared in advance. When the topper unit needs to be installed, the heavy electronic display component can be quickly secured to the pre-positioned base units using the prepared fastening systems, thereby achieving reliable mounting security while significantly reducing on-site installation effort and costs compared to creating structural supports during installation.
4Stability of the object's composition
If enhanced strength mounting components are used to stably mount the vehicle topper, then mounting stability improves, but the system becomes more complex and costly
Solution Approach 1:
The mounting system incorporates self-aligning and self-securing features where the fastening mechanisms automatically engage with the base units and topper unit interfaces. The cross bars and base units are designed with inherent alignment features that guide proper positioning during installation, and the fastening system provides automatic locking or securing actions. This self-service capability achieves stable mounting without requiring complex adjustment mechanisms or multiple installation steps, thereby maintaining mounting stability while minimizing system complexity.

AI summary
Systems and method for vehicle top advertising are provided. Cross bars span a roof of the vehicle. A vehicle top unit with an electronic display is attached to the cross bars. One or more exterior coverings are connected to at least one of: the cross bars and the vehicle top unit. Wiring is extended from a power source located outside of the vehicle top unit, along at least one of the cross bars, and to the vehicle top unit to place the electronic display in electrical connection with the power source. The exterior coverings each cover at least a respective portion of the wiring.
