Folding Camping Bicycle Trailer for Long Sleeping Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camping bicycle trailers are expensive to produce and impractical for cycling due to their large size when in use, as they require a long platform that is cumbersome to maneuver.
Innovation Solution
A three-part frame structure that pivots between a folded and unfolded position, allowing for a comfortable 2-meter lying surface while maintaining compact dimensions for easy towing, using a child trailer chassis for cost optimization and incorporating foldable frame structures and a tent tarpaulin for stability and storage, with a solar cell for charging a battery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a long platform is used to provide a comfortable lying area, then the lying surface length is improved, but the trailer becomes cumbersome and difficult to maneuver
Solution Approach 1:
The platform is divided into multiple segments (first platform, second platform, third platform) that can be articulated relative to each other. When folded, the segments are positioned to minimize the overall length, making the trailer maneuverable. When unfolded, the segments form a continuous 2-meter lying surface.
Solution Approach 2:
The platform uses an articulated mechanism with pivot points that allow dynamic transformation between a compact folded state for easy maneuvering and an extended unfolded state for comfortable lying. The articulation enables the platform to adapt its configuration based on operational needs.
2Adaptability or versatility
If custom-made bicycle trailers are produced in small quantities, then the specific camping functions are achieved, but the manufacturing cost increases significantly
Solution Approach 1:
The trailer is designed based on a standard two-seater child trailer chassis that can serve multiple purposes. The base chassis is a universal platform that can be used for both child transport and camping activities, eliminating the need for completely custom manufacturing and reducing production costs through economies of scale.
Solution Approach 2:
The camping-specific features (platform, frame structures, tarpaulin) are designed as separable modules that can be attached to or removed from the standard child trailer chassis, allowing for cost-effective production using standardized base components.
3Length of moving object
If the trailer is designed to be compact when folded, then the maneuverability is improved, but the storage space for camping equipment is reduced
Solution Approach 1:
The platform segments are designed to nest within each other when folded, with the second and third platforms positioned to fit into the space created by the first platform. This nesting arrangement minimizes the overall folded length while preserving the volume needed for storage compartments.
Solution Approach 2:
Storage space is optimized by utilizing vertical dimension and three-dimensional space arrangement rather than only horizontal extension. The foldable frame structures create usable storage volume without increasing the horizontal footprint when folded.

AI summary
The invention relates to a camping bicycle trailer (11) for providing a sleeping area (20) and for covering the sleeping area (20) with a tent tarpaulin (13), comprising a first platform (15), an axle (23) attached to the first platform (15) and to which two wheels (25) are rotatably attached, a first frame structure (29) extending above and below the first platform (15), and a drawbar (27) which is attached at its first end to the first frame structure (15) and can be coupled to a bicycle at its second end (27b). The first frame structure (15) is pivotally connected to a second platform (17), and the second platform (17) is pivotally connected to a third platform (19).This allows the second and third platforms (17,19) to pivot between a folded position, in which the trailer (11) is ready to drive, and an unfolded position, in which the platforms (15,17,19) form the lying surface (20).
