Vehicle Side Display Area Expansion via Modular Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicles with liquid crystal displays for advertising or warnings have smaller displays due to wheel constraints, reducing their effectiveness in capturing public attention.
Innovation Solution
A vehicle design with an eight-wheel structure allowing for smaller diameter wheels, enabling a larger display area by stretching the side display lower than the wheels and wider than the wheel spacing, and incorporating modular units with sliding doors to maximize display space and ingress/egress openings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the lower edge of the display is positioned above the top of the wheels to avoid overlap, then the display can be implemented without structural interference, but the display size becomes small relative to the vehicle size, reducing advertising effectiveness
Solution Approach 1:
The vehicle is divided into multiple modular units (front end unit, rear end unit, and intermediate units) that can be connected along the longitudinal axis. This segmentation allows the display to extend across multiple units, achieving a large display area without requiring a single complex structural design. The display panels are distributed across these modular units, enabling the display to stretch wider than the wheel spacing while maintaining manageable structural complexity.
Solution Approach 2:
The display is configured to extend in multiple dimensions: vertically lower than the wheel tops and horizontally wider than the wheel spacing. By utilizing the full available space in both vertical and horizontal dimensions, the display achieves maximum area without interfering with the wheel structure. The curved or bent lower edge at both ends further optimizes the display shape to avoid wheel overlap while maximizing visible area.

If eight wheels are used instead of conventional four wheels, then smaller diameter wheels can be used which allows for a more spacious passenger compartment and larger display area, but the device complexity increases
Solution Approach 1:
The eight-wheel structure is organized into four pairs (front wheels, rear wheels, and intermediate wheels) that are distributed along the longitudinal axis. This segmentation of the wheel system allows for smaller wheel diameters while maintaining structural manageability. Each wheel pair supports a portion of the vehicle weight, and the modular unit structure (front end unit, rear end unit, intermediate units) aligns with this wheel arrangement, making the complex eight-wheel configuration more manageable.
Solution Approach 2:
The eight wheels serve multiple functions: they provide vehicle support, enable the vehicle to navigate tight spaces, and create the structural framework that allows for a spacious passenger compartment and large display area. The smaller wheel diameter itself is a functional advantage that enables the overall design goals. The modular unit structure with sliding doors further enhances versatility by allowing flexible configuration.

If the side display stretches wider than between inside ends of the wheels, then the display area is maximized relative to vehicle size, but the display may overlap with the wheels, causing visual interference
Solution Approach 1:
The lower edge of the display is curved or bent upwards at both ends to avoid overlapping with the wheels. This curvature allows the display to stretch wider than the wheel spacing while maintaining a clean visual separation from the wheel structures. The curved edges follow the contour needed to clear the wheel tops, creating an aesthetically pleasing shape that maximizes display area without visual interference from the wheels.

AI summary
A vehicle includes a substantially box-shaped body, wheels disposed on four corners of the vehicle, and at least one side display disposed on either or both exterior side surfaces of the body for displaying images and videos. The side display stretches lower than a top of the wheels along the vertical axis of the vehicle and wider than between inside ends of the wheels along the longitudinal axis of the vehicle. The lower edge of the side display is curbed or bent upwards at both ends to avoid overlapping with the wheels.
