Solution Overview

Problem

Conventional wheeled vehicle loading devices are difficult to operate, transport, and store due to their bulky and inflexible designs, and permanently attached systems limit the versatility of loading platforms.

Innovation Solution

A portable ramp with a novel collapsing and folding design that allows sections to slide and fold sideways, reducing storage size while maintaining versatility through adjustable width and length, featuring spring-loaded locks for secure positioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional ramps are designed to be wide and long for loading vehicles, then they provide adequate loading capability, but they become bulky and difficult to transport and store

Engineering Contradiction:
Improveloading capabilityVSAvoidstorage size
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The ramp is divided into multiple sections that can be folded relative to each other. Each section contains rails, crossbeams, and support structures that can be collapsed into a compact configuration while maintaining the ability to form a complete loading ramp when extended.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The ramp sections are designed to nest within each other when collapsed, with crossbeams sliding along rails and support structures collapsing inward. This nesting arrangement allows the ramp to reduce to a fraction of its extended volume for storage and transport.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Volume of moving object

If ramps are made foldable to reduce storage size, then portability improves, but structural stability and strength may be compromised

Engineering Contradiction:
Improvestorage sizeVSAvoidstructural stability
Core Design Contradiction:
Volume of moving objectVSStrength

Solution Approach 1:

The ramp includes pre-positioned locking mechanisms that engage automatically or manually when sections are extended into the loading position. These locks secure the ramp sections together, providing structural stability equivalent to a rigid ramp when deployed.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The ramp transitions from a static rigid structure to a dynamic collapsible structure that maintains rigidity when needed. The folding sections provide flexibility for storage, while locking mechanisms provide rigidity during use, allowing the structure to adapt its properties based on operational requirements.

Inventive Principle:
Principle #15Dynamics

3Device complexity

If single lane ramps are used to reduce complexity, then manufacturing simplifies, but stability decreases and storage becomes twice as difficult due to needing two ramps

Engineering Contradiction:
Improveramp design simplicityVSAvoidramp stability
Core Design Contradiction:
Device complexityVSStability of the object's composition

Solution Approach 1:

The invention combines multiple ramp lanes into a single integrated structure that functions as one stable unit. The parallel rails and crossbeams create a wide stable base that prevents rolling or shifting, eliminating the need for multiple separate ramps while maintaining ease of storage.

Inventive Principle:
Principle #5Merging (Combining)

4Length of moving object

If folding ramps decrease length but not width, then length is reduced for storage, but the ramp remains bulky and equally difficult to transport

Engineering Contradiction:
Improveramp lengthVSAvoidoverall storage volume
Core Design Contradiction:
Length of moving objectVSVolume of moving object

Solution Approach 1:

The ramp collapsing mechanism operates in multiple dimensions simultaneously - sections fold lengthwise to reduce length, while crossbeams collapse widthwise to reduce width. This multi-dimensional collapsing approach reduces the ramp's volume in all directions, creating a compact package for storage and transport.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
