Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display sign systems lack mobility and flexibility in raising and lowering signage for effective communication over large areas, especially in contexts like auctions where items are distributed across land.
Innovation Solution
A mobile elevating apparatus with a mobile base, extendable and retractable lift assembly, and a display sign that can be raised and lowered, equipped with a power source and control assembly for remote operation, allowing for flexible positioning and enhanced visibility of information across an area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a display sign system is made stationary and fixed in one location, then it provides stable support and easy structure, but it lacks mobility and cannot be repositioned to communicate information over large areas
Solution Approach 1:
The patent applies the dynamics principle by transforming the stationary display sign into a mobile system. The base unit is equipped with wheels or casters that allow it to be easily moved across different locations. The lift assembly can be extended and retracted to adjust the height of the display sign, enabling it to adapt to various communication needs and locations without requiring a fixed installation structure.
2Illumination intensity
If the display sign is placed at ground level, then it has simple structure and easy positioning, but it lacks visibility for effective communication over large areas
Solution Approach 1:
The patent applies the dimensionality change principle by adding vertical height to the display sign through the lift assembly. Instead of only moving the display sign horizontally across different locations, the system now operates in the vertical dimension as well. The lift assembly can extend to raise the display sign to elevated positions, significantly improving visibility over large areas while maintaining a relatively simple base structure.
3Illumination intensity
If the display sign is raised to high positions for better visibility, then communication effectiveness improves, but it requires complex lifting mechanisms and more energy
Solution Approach 1:
The patent applies the mechanics substitution principle by replacing complex mechanical lifting mechanisms with simpler, more energy-efficient systems. The lift assembly uses electric motors or hydraulic systems that can be controlled to extend and retract, providing the necessary lifting force with minimal energy consumption. These systems can hold the display sign at elevated positions without requiring continuous energy input, unlike traditional mechanical counterweight systems.
4Adaptability or versatility
If the display sign is made mobile and repositionable, then it can communicate information across large areas, but it requires complex base structures and control systems
Solution Approach 1:
The patent applies the universality principle by designing the base unit to perform multiple functions with a single integrated structure. The base serves as the platform for the display sign, houses the power source, contains the control system, and provides the mobility mechanism through wheels or casters. This multi-functional design reduces the need for separate components and simplifies the overall control system while maintaining full repositionability and adaptability.

AI summary
A mobile elevating apparatus may include a mobile base having a front and a rear with a longitudinal axis being defined between the front and rear, with the mobile base comprising a frame and a wheel assembly mounted on the frame to support the frame in a manner permitting mobility. The apparatus may also include a lift assembly including at least one tier and being mounted on the frame and being extendable and retractable with respect to the frame to raise and lower a top of the lift assembly, an object mounted on the top of the lift assembly such that extension and retraction of the lift assembly raises and lowers the object, a power source positioned on the mobile base; and a control assembly mounted on the mobile base. In embodiments, the object may comprise a display sign.
