Removable Trailer Seat Mounting for Stable Load Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multipurpose trailers face challenges in providing improved safety and ease of use, particularly in adapting to different passenger loads and ensuring secure attachment of removable seats.
Innovation Solution
A multipurpose trailer design with removable seats that can be attached in multiple positions, featuring upper and lower seat attachments integrated with the chassis or sheet element, and secured by straps and connectors, allowing for adjustable weight distribution and enhanced stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the trailer is designed with fixed seat positions, then the manufacturing is simpler, but the adaptability to different passenger loads is reduced
Solution Approach 1:
The seat attachment system is segmented into multiple attachment points distributed along the trailer chassis. These discrete points allow seats to be positioned at different locations (e.g., central or lateral positions) depending on passenger load requirements, providing adaptability without requiring a completely different attachment system for each configuration.
Solution Approach 2:
The attachment system is designed with universal characteristics where the same attachment mechanism can accommodate seats in multiple positions. The plurality of attachment points serves multiple functions: securing seats centrally for single passengers, laterally for multiple passengers, or removing seats entirely for cargo transport, eliminating the need for separate attachment systems for different use cases.
2Ease of manufacture
If the seat attachments are integrated with the sheet element, then the manufacturing is easier, but the strength of attachment may be reduced
Solution Approach 1:
The attachment system merges the seat attachment function with the existing sheet element structure. Attachment points are integrated into the sheet element rather than being separate components, simplifying manufacturing by eliminating additional attachment hardware while still providing secure seat mounting capability through the distributed attachment point network.
Solution Approach 2:
The sheet element is designed with localized reinforcement or specific structural features at the attachment point locations. This allows the attachment points to have the necessary strength and load-bearing capacity while the rest of the sheet element maintains its original design, achieving both ease of manufacture and adequate attachment strength.
3Reliability
If the distance between upper and lower seat attachments is fixed, then the attachment mechanism is simpler, but the ability to prevent unintentional release is reduced
Solution Approach 1:
The distance between upper and lower seat attachments is made variable rather than fixed. The attachment mechanism allows adjustment of the vertical spacing between attachment points, enabling the system to adapt to different seat configurations and load conditions. This dynamic adjustment capability enhances security by allowing optimization of attachment geometry for different scenarios while preventing unintentional release.

AI summary
A multipurpose trailer for carrying at least one person. In some embodiments, the trailer includes a chassis forming a load carrying structure of the multipurpose trailer, a sheet element supported by the chassis, and a removeable seat. In some embodiments, the multipurpose trailer is configured for attachment of the removeable seat in at least two transverse positions, and one of the transverse positions is centered in relation to a transverse direction of the multipurpose trailer.
