Rotatable Stair System for RV Deck Space Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional foldable stairs for recreational vehicles (RVs) require external space for installation and demand additional parking space due to their perpendicular orientation, while non-foldable systems combining stairs and decks are complex to install and disassemble.
Innovation Solution
A stair and deck system that can be folded into the structure and deployed with stairs positioned at a selected side of the deck, featuring a convertible deck platform, a rotatable stair system, a top hatch, and a handlebar for easy operation and orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional foldable stairs are used for RVs, then they can be folded into the structure, but they require external space for installation and additional parking space due to perpendicular orientation
Solution Approach 1:
The stair system is made rotatable relative to the deck platform, allowing dynamic repositioning between multiple orientations (e.g., perpendicular, parallel, or angled positions). This dynamic capability enables the stairs to adapt to different parking configurations and space constraints without requiring fixed external installation space.
Solution Approach 2:
The invention introduces rotational movement in a third dimension, allowing the stair system to change its angular orientation relative to the deck platform. This dimensional freedom enables the stairs to be positioned at selected angles rather than fixed perpendicular orientations, optimizing space utilization during parking and storage.
2Stability of the object's composition
If non-foldable stair and deck systems are combined, then structural integrity is improved, but installation and disassembly become complex
Solution Approach 1:
The stair and deck system is divided into separate, modular components (deck platform, stair system, top hatch) that can be independently assembled and disassembled. The rotatable connection between components provides stable structural integrity when assembled, while allowing easy deployment and storage when disassembled, resolving the contradiction between stability and ease of operation.
Solution Approach 2:
The system incorporates dynamic rotational connections that allow the stair system to be easily rotated and positioned relative to the deck platform during installation and disassembly operations. This dynamic feature simplifies the assembly process while maintaining stable structural integrity when in use, eliminating the complexity associated with non-foldable integrated systems.
3Ease of operation
If stairs are positioned perpendicular to the door opening wall, then access is provided, but additional parking space is demanded
Solution Approach 1:
The rotatable stair system allows dynamic adjustment of the stair orientation relative to the deck platform and door opening. Users can rotate the stairs to optimal angles for access while minimizing the space required for parking, transforming a fixed perpendicular configuration into a flexible, space-efficient arrangement.
Solution Approach 2:
The invention changes the angular parameter of the stair orientation from a fixed perpendicular position to variable angles. This parameter adjustment enables optimization of both access accessibility and parking space requirements, allowing the stair system to adapt to different spatial constraints and user needs.

AI summary
A stair-deck system integrates the deck system and stair system. The deck system seamlessly integrates several components, including the top hatch, deck, stair system, and handle link. The handle link establishes a connection between the top hatch and the deck, offering the operator control over the open and close processes. The stair system, situated on the deck, can be deployed as needed. In its fully deployed configuration, the top hatch functions as a roof, and the stair system can be rotated to multiple orientations for enhanced convenience. The stair system integrates a foldable stair, stair platform, and handle posts, forming a comprehensive system mounted on the deck. Following the full deployment of the deck system, the operator can manually unfold the stairs, rotate the entire system to one of three orientations based on the user's preference and convenience and place the handle post.
