Portable advertising platform systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing advertising platforms, such as portable signs and retail product displays, face challenges with stability on uneven ground, wind resistance, limited size, and maneuverability, particularly in confined spaces, and require frequent leveling and braking mechanisms that are cumbersome and prone to wear.
Innovation Solution
A portable lightweight advertising platform system made from aluminum tubes with a wheel assembly, leg levelers, and an upper web that can telescope and stretch, allowing items to be elevated and securely fastened, providing wind resistance and easy maneuverability, and featuring a braking mechanism integrated into the leg levelers for stability on rough terrain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional portable signs (A-frames, sandwich boards) are used, then they can display advertising information, but they require level ground and are easily blown over by wind
Solution Approach 1:
The platform is divided into modular components: a base unit with wheel assembly, telescoping leg levelers, and an upper web structure. This segmentation allows each component to perform its specific function independently - the wheel assembly provides mobility on various terrains while the telescoping legs provide stabilization on uneven ground.
Solution Approach 2:
The leg levelers incorporate telescoping mechanisms that can dynamically adjust their length to compensate for uneven ground surfaces. This dynamic adjustment capability allows the platform to maintain stability across varying terrain conditions without requiring pre-leveling of the ground.
2Ease of manufacture
If signs are placed at ground level, then they are easy to attach, but they are not visible enough to engage passersby attention
Solution Approach 1:
The platform elevates the advertising display from ground level to an elevated position using its telescoping structure. By adding the vertical dimension, the sign becomes visible above traffic and obstacles while maintaining ease of attachment through the standardized webbing and fastening system on the upper web structure.
3Stability of the object's composition
If fixed braking mechanisms are added to prevent uncontrolled rolling, then stability is improved, but the device becomes more complex and brakes wear out
Solution Approach 1:
The leg levelers serve a dual function: they provide stabilization on uneven ground and simultaneously act as friction brakes when the platform is stationary. This self-service approach eliminates the need for separate braking mechanisms, reducing overall device complexity while maintaining stability.
4Reliability
If the cart is made heavy and uses larger wheels, then it can handle rough terrain better, but maneuverability in confined spaces deteriorates
Solution Approach 1:
The wheel assembly is designed with swivel-capable wheels that can dynamically adjust their orientation. This dynamic wheel configuration allows the platform to navigate both rough terrain and confined spaces effectively, combining the benefits of larger wheels for terrain handling with the maneuverability of swivel capability.
5Volume of moving object
If the display size is limited to the device's display window, then the device remains compact, but the information cannot be displayed effectively
Solution Approach 1:
The upper web structure extends vertically from the base unit, utilizing the vertical dimension to increase display area without significantly increasing the device's horizontal footprint. This allows for larger, more effective advertising displays while maintaining a compact overall device size for portability.

AI summary
A portable, aluminum advertising platform system for store front and street side promotions. This rugged, lightweight platform has multiple vertical mounts and substantially stretches both horizontally and vertically providing numerous configurations. Supported signs and products are attached only at the top which allows them to freely swing; wind resistant. The structure is made from 2 aluminum tubes that slide inside each other; telescopes. Fastening occurs using thumb screws attached to the outer tubes that when twisted, pinches the inside interconnecting tubes. Tubes come in 1 to 4 foot lengths and can couple together to form much larger members. The 2 side frames are tubes welded together. The 4 leg levelers telescope 3 feet both horizontally and vertically to level the cart on rough uneven terrain. Levelers also act as durable brakes when any wheels are lifted off the ground. Detachable large 8 inch wheels swivel for easy maneuvering.
