Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional advertisement systems on billboards and moving vehicles are expensive, time-consuming to replace, and vulnerable to weather and road debris damage, with digital solutions being impractical and unsafe for semi-tractor trailers.
Innovation Solution
A secure, adaptable, and weather-resistant digital advertisement system featuring a chassis-mounted display panel with magnetically secured display modules, protected by silicone casing, and electronic components housed within a locking panel, allowing for dynamic content updates via GPS and geofencing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If digital billboards are mounted on moving vehicles, then advertising effectiveness is improved, but safety and security deteriorate
Solution Approach 1:
The display system is divided into multiple independently mounted display modules that can be securely attached to the vehicle chassis. Each module is a separate unit that can be individually secured, allowing the system to maintain advertising functionality while improving safety through distributed mounting rather than a single large unstable structure
Solution Approach 2:
The chassis is pre-installed on the vehicle before the display modules are attached. This preliminary mounting provides a stable, secure foundation that addresses safety concerns before the advertising display components are added, ensuring that the structural base is properly secured to the vehicle frame
2Adaptability or versatility
If advertisements are painted directly on vehicle surfaces, then customization is improved, but durability deteriorates
Solution Approach 1:
Instead of painting advertisements directly on the vehicle, the system uses digital display modules that can show reproduced images and videos. This allows the same advertisement content to be displayed without physical contact with the vehicle surface, maintaining customization flexibility while eliminating the durability problems of painted ads exposed to weather and road debris
Solution Approach 2:
The mechanical process of painting advertisements is replaced with an electronic digital display system. The display modules use electronic screens to show advertising content, substituting the mechanical painting process with an electronic solution that is not subject to weathering, fading, or peeling
3Reliability
If vinyl graphics are applied to vehicles, then weather resistance is improved, but adaptability deteriorates
Solution Approach 1:
The advertising display transitions from static vinyl graphics to dynamic digital display modules. The display modules can change content electronically, allowing advertisements to be updated, rotated, and customized without physical replacement, thereby providing both weather resistance (since the modules are protected enclosures) and high adaptability for different advertising campaigns
4Ease of operation
If display modules are mechanically fastened to chassis, then ease of installation is improved, but vibration resistance deteriorates
Solution Approach 1:
The mounting system combines multiple fastening methods: mechanical fasteners provide the basic attachment, while magnetic elements are integrated into the display modules to work together with the mechanical fasteners. This combination of mounting mechanisms provides both ease of installation (modules can be easily attached and detached) and vibration resistance (the dual-system approach ensures modules remain secure under vibrational stress from the moving vehicle
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
The system provides a durable, economical, and secure digital advertising solution for moving vehicles, reducing vibrational stress and eliminating the need for manual replacement, while being resistant to weather and road debris.
Implementation Method 1
The magnets are useful in securing the display modules to the chassis and reducing the vibrational effects that may otherwise be present if using non-magnet, mechanical fasteners.
