Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable ramps used for wheelchairs face challenges in maintenance due to storage requirements and lack of portability, and they are not easily convertible for use as a billboard stand.
Innovation Solution
A foldable ramp design featuring a folding guide portion, inclination portions, support portions, and a mounting system that allows for easy storage and conversion into a billboard stand, with reinforcement and advertisement display capabilities, facilitating storage, transport, and height adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a foldable ramp is stored in a separate storage space, then the ramp can be folded for compact storage, but maintenance becomes difficult
Solution Approach 1:
The patent combines the ramp structure with a billboard stand structure into a single integrated unit. The ramp folding mechanism is merged with the stand's support legs, allowing the entire assembly to be folded into a compact configuration for storage while remaining accessible for maintenance. This eliminates the need for separate storage spaces and makes maintenance easier since all components are housed together.
2Ease of operation
If a foldable ramp is designed for compact storage, then portability is improved, but structural stability may be compromised
Solution Approach 1:
The patent employs dynamic folding mechanisms where the ramp and stand components can transition between extended and folded states. Hinged joints and movable connections allow the structure to be collapsed for portability while maintaining rigid stability when deployed. The reinforcement bars and support legs are designed to lock into stable positions during use, ensuring structural integrity despite the foldable design.
3Adaptability or versatility
If the ramp is used as a billboard stand, then versatility is improved, but the ramp function may be compromised
Solution Approach 1:
The patent designs a unified structure where the same components serve dual purposes: the inclined plane functions as both a wheelchair ramp and a billboard support surface. The reinforcement bars and support legs provide structural integrity for both applications. Advertising panels can be mounted on the stand portion while the ramp portion maintains its accessibility function, allowing the same structure to reliably perform both ramp and billboard stand functions.
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 design enables easy storage and transport, firm support, and versatile use as a billboard stand, enhancing user convenience and efficiency by allowing for easy installation and adjustment.
Implementation Method 1
a first inclination portion which has one side rotatably coupled to one side of the folding guide portion to form the inclination surface together with the folding guide portion
Implementation Method 2
a first support portion which has one side rotatably coupled to the other side of the first inclination portion and is supported by a floor
