Utility Vehicle Display Panels for Fast Motif Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing utility vehicle structures face high costs and complexity in changing advertising motifs on side and rear wall doors, particularly for leasing vehicles, due to the need for high-quality materials and frequent re-lettering.
Innovation Solution
Integration of a pixel-technological display field with individually drivable display pixels on components like door leaves, side walls, and roof walls, allowing for flexible and dynamic motif changes without the need for physical re-lettering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional physical lettering is used on utility vehicle structures, then high-quality advertising display is achieved, but changing motifs becomes complex and costly
Solution Approach 1:
The patent uses digital copies (display pixels) to replace physical lettering materials. Instead of applying physical adhesive lettering that requires removal and replacement, the invention uses electronic display technology that can change motifs through digital signals, eliminating the need for physical re-application while maintaining high-quality visual display.
Solution Approach 2:
The invention replaces the mechanical process of physical lettering application and removal with an electronic display system. The display pixels are controlled electronically to show different motifs, eliminating the manual labor, materials, and time required for physical re-lettering while enabling rapid motif changes.
2Reliability
If high-quality materials are used for lettering on leasing vehicles, then advertising quality is maintained, but production and maintenance costs increase
Solution Approach 1:
The patent employs relatively inexpensive display pixels that can be easily replaced or updated compared to expensive physical lettering materials. The display system uses energy-consuming but material-light technology, where the 'consumable' is electrical energy rather than physical materials, significantly reducing material costs while maintaining display quality.
Solution Approach 2:
The invention changes the fundamental parameter from physical material quality to electronic display capability. Instead of investing in durable physical lettering materials that cost thousands of euros, the system uses adjustable electronic parameters (pixel illumination, color, brightness) to achieve equivalent or superior advertising quality at lower material cost.
3Adaptability or versatility
If physical lettering is applied to utility vehicle structures, then advertising motifs are displayed, but time and resources are consumed for changes
Solution Approach 1:
The patent prepares multiple motif configurations in advance as digital data, ready to be displayed instantly. Unlike physical lettering that requires on-site application, the digital motifs are pre-programmed and can be activated immediately through electronic control, eliminating the time required for physical installation while maintaining motif flexibility.
Solution Approach 2:
The invention replaces the time-consuming mechanical process of physical lettering application with instantaneous electronic signal transmission. The display pixels respond immediately to control signals, enabling motif changes in seconds rather than hours or days, thus eliminating the time loss associated with physical re-lettering while preserving advertising flexibility.

AI summary
A pixel-technological display field for displaying changing motifs is attached to the outside of at least one component of a utility vehicle structure or is structurally integrated in to the at least one component. The display field has a multiplicity of separately controllable display pixels. In an embodiment the display field is self-luminous and produces a light emission that is less than +0.5 cd/m2 in comparison to an averaged, relative ambient light. In an embodiment the display field protrudes from an outer surface of the at least one component by less than 15 mm.
