Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing modular ramp constructions face difficulties in adapting to varying obstacle heights, such as doorsteps, due to fixed module heights and complex assembly processes, which can lead to uncomfortable passage for wheelchairs and heavy objects.
Innovation Solution
The introduction of wedge elements with adjustable height and length, featuring releasable attachment means that can be easily attached and detached without tools, allowing for customizable integration under modular ramp constructions to bridge height differences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If fixed-height modules are used in modular ramp construction, then the structural stability and simplicity of assembly are improved, but the adaptability to different obstacle heights deteriorates
Solution Approach 1:
The wedge element is divided into multiple sections that can be independently adjusted or removed. This segmentation allows the ramp construction to be adapted to different obstacle heights by selectively using different numbers or combinations of sections, while maintaining the overall structural stability through the modular design.
Solution Approach 2:
The wedge element introduces a dynamic adjustment capability to an otherwise static modular ramp system. By allowing the wedge element to be adjusted to different positions and configurations, the system can dynamically adapt to various obstacle heights while maintaining structural integrity through the engagement means.
2Adaptability or versatility
If complex assembly means are used to provide adjustable wedge elements, then the adaptability to different heights is improved, but the device complexity and assembly time increase
Solution Approach 1:
The engagement means is designed to enable easy attachment and detachment of the wedge element without requiring complex tools or procedures. The self-service design allows users to independently adjust the wedge element position and configuration, reducing assembly complexity while maintaining full adjustability for different heights.
Solution Approach 2:
The wedge element is designed as a separate, extractable component that can be independently adjusted or removed. This extraction approach simplifies the overall system by separating the adjustment function into a distinct module, reducing device complexity while preserving adaptability to different obstacle heights.
3Stability of the object's composition
If dowel elements are used to attach adjacent modules, then the structural stability is improved, but the ease of disassembly deteriorates
Solution Approach 1:
The engagement means incorporates self-service features that allow the wedge element to be easily attached and detached without requiring complex tools or procedures. This design maintains attachment stability during use while enabling simple disassembly when needed, improving ease of operation.
Solution Approach 2:
The attachment system transitions from a static, permanent connection to a dynamic, reversible connection. The engagement means allows the wedge element to be securely attached during operation but can be easily detached when adjustment or removal is needed, balancing stability with ease of operation.

AI summary
The present invention relates to a modular ramp constructions that facilitate the passage of objects over obstacles on a surface such as a doorstep or a flight of stairs. Specifically the present invention relates to a construction that facilitates the passage of a wheelchair or other appliances used by physically handicapped persons over such obstacles. The construction comprises wedge elements (1) that can be adapted to the given dimensions and requirements of a ramp construction, to which purpose the length of the wedge elements (1) can easily be shortened and where the wedge elements (1) are provided with means (6) for releasable attachment to adjacent tile elements (8) of the modular ramp construction, thereby making it possible quite easily to assemble and afterwards dismantle the construction when it is to be adapted to another application.
