Travel Trailer Modular Shell Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manufacturing of towable travel trailers is labor-intensive due to the need for separate components and complex assembly processes, which complicates the customization and rapid assembly of these recreational vehicles.
Innovation Solution
A travel trailer design featuring molded exterior and interior shells that connect via mating edges, with pre-defined openings for passageways and integrated features such as pre-molded floor and ceiling structures, storage areas, and a wheeled chassis for easy assembly and attachment to a tow vehicle, minimizing labor and assembly time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional separate components and complex assembly processes are used, then customization options are available, but manufacturing becomes labor-intensive and assembly time increases
Solution Approach 1:
The patent combines multiple separate components (floor, ceiling, walls, cabinetry, appliances, fixtures) into pre-assembled modular sections that are manufactured separately and then quickly joined together. This merging of components into integrated modules reduces on-site assembly labor while preserving customization options through selective module combination.
Solution Approach 2:
The travel trailer is divided into distinct modular sections (exterior shells, interior shells, cabinetry modules, appliance modules) that can be independently manufactured and customized. These segmented modules are then assembled together, allowing for both customization and reduced assembly time through standardized connection interfaces.
2Adaptability or versatility
If separate components are brought to the travel trailer for installation during construction, then customization is accommodated, but the manufacturing process becomes labor intensive
Solution Approach 1:
Components such as cabinetry, appliances, fixtures, and interior finishes are pre-assembled and pre-configured into modular sections during the manufacturing process. This preliminary assembly of components into integrated modules simplifies the final construction process while maintaining customization flexibility through different module selections.
3Reliability
If traditional assembly methods are used, then structural integrity can be maintained, but labor costs and assembly time increase
Solution Approach 1:
Structural components (exterior shells, interior shells, floor, ceiling, walls) are combined into pre-assembled modular sections that maintain structural integrity through integrated design. These merged modules are then quickly connected using standardized joining methods, reducing assembly time while preserving structural strength.
