Collapsible Trailer House Structure With Floating Expansion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trailer houses are fixed in size with a flat top structure, limiting their usable area and unable to float on water, restricting their use range.
Innovation Solution
A collapsible lifting/lowering mobile trailer house with a frame-based structure that includes a house body, sliding rails, and a driving module for vertical movement, combined with water buoyancy compartments to enable floating on water and expand the usable area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the trailer house is fixed in size with a flat top structure, then the structure is simple and stable, but the usable area is limited
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed-size trailer house into a collapsible structure that can change between expanded and contracted states. The lifting/lowering frame with sliding rails enables the house body to dynamically adjust its configuration, increasing usable area when expanded while maintaining simplicity when contracted.
Solution Approach 2:
The patent segments the house body into multiple collapsible sections connected by lifting/lowering frames. This segmentation allows the structure to be divided into modular units that can be independently adjusted, enabling the expansion of usable area through vertical deployment of these segmented components.
2Adaptability or versatility
If the trailer house is designed for land use only, then the structure is simple, but the use range is limited
Solution Approach 1:
The patent applies the universality principle by designing the trailer house to perform multiple functions across different environments. The addition of water buoyancy compartments enables the structure to function both on land and on water, making it a multi-environment recreational vehicle without significantly complicating the overall design.
Solution Approach 2:
The patent merges the land-based trailer house structure with water buoyancy compartments to create a hybrid vehicle. This combination integrates two previously separate functions (land transportation and water floating) into a single unified structure, expanding adaptability while maintaining structural coherence.
3Adaptability or versatility
If water buoyancy compartments are added to enable floating, then the use range is widened, but the device complexity increases
Solution Approach 1:
The patent applies the nested doll principle by integrating water buoyancy compartments within the existing frame structure. The buoyancy compartments are nested inside or alongside the frame members, allowing the water-floating function to be incorporated without adding significant external complexity to the overall vehicle structure.
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 structure allows for easy operation and reliable use, with a herringbone design expanding the usable area and enabling water buoyancy, enhancing the recreational vehicle's versatility.
Implementation Method 1
water buoyancy compartments are arranged at the bottom of the frame and on the outer sides of supporting plates, so that the recreational vehicle can float on water

AI summary
Provided are a collapsible lifting/lowering mobile trailer house and a recreational vehicle. The trailer house includes a frame; a house body is provided on the frame; the house body comprises roofs, a first side wall plate, a second side wall plate, and a lifting/lowering frame; the roofs are hingedly connected to the lifting/lowering frame through connecting rods; upper ends of the first side wall plate and the second side wall plate are slidably connected to the inner sides of the roofs; the lifting/lowering frame is slidably connected to vertically arranged sliding rails; and the lifting/lowering frame is provided with driving modules, which drive the lifting/lowering frame to move up and down along the sliding rails, so as to drive the roofs, the first side wall plate, and the second side wall plate to be opened/closed.
