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 to vertically move the lifting/lowering frame, enabling opening and closing of the house body, and incorporating water buoyancy compartments for floating on water.
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 easy to manufacture, but the usable area is limited
Solution Approach 1:
The trailer house employs a collapsible frame structure that can dynamically change between expanded and collapsed states. The frame includes telescopic columns and articulating joints that allow the structure to transform from a compact flat configuration to an expanded three-dimensional configuration with increased usable area, while maintaining structural integrity throughout the transformation.
Solution Approach 2:
The invention transitions from a two-dimensional flat top structure to a three-dimensional volumetric structure by vertically extending the frame and walls. This dimensional change creates additional interior space and usable area while the frame can be collapsed back to a flat configuration for transport, effectively utilizing vertical space without permanently increasing complexity.
2Adaptability or versatility
If the trailer house is fixed in size, then the structure is stable and reliable, but the use range is restricted and unable to float on water
Solution Approach 1:
The trailer house is designed with multi-functionality to operate in multiple environments including land and water. The collapsible frame structure can be configured for stable placement on land, while the same structure can be adapted for buoyant operation on water. This universal design expands the use range without requiring entirely separate structures for different environments.
Solution Approach 2:
The dynamic collapsible frame allows the structure to adapt its configuration based on the operating environment. For water operation, the frame can be expanded to a buoyant configuration; for land operation, it can be configured for stable ground contact. This dynamic adaptability maintains structural reliability across different uses while expanding versatility.
3Area of moving object
If the top structure is flat and fixed, then the manufacturing is simple, but the expansion of usable area is limited
Solution Approach 1:
The frame structure is divided into modular segments including telescopic columns, articulating joints, and panel sections. Each segment can be manufactured independently using standard fabrication processes, then assembled to create the expanded three-dimensional structure. This segmentation allows complex functionality to be achieved through repeated modular units rather than a single complex custom-manufactured structure.
Solution Approach 2:
The collapsible frame employs a nested configuration where smaller structural elements are contained within larger ones during the collapsed state. The telescopic columns nest within each other, and panels fold into the overall structure, allowing the complex three-dimensional structure to be compacted into a simple flat configuration for transport and storage, effectively hiding complexity during non-use.
4Adaptability or versatility
If the trailer house cannot float on water, then the structure is simpler, but the use range is restricted
Solution Approach 1:
The same collapsible frame structure serves dual purposes: providing stable land-based accommodation and enabling water-based operation. The frame's articulating joints and telescopic columns allow it to achieve a buoyant configuration when needed, eliminating the need for separate watercraft and land vehicle structures, thereby expanding use range without proportionally increasing overall system complexity.
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 a wider usable area through a herringbone design and enables the trailer house to float on water, enhancing its use range and operational reliability.
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
