Removable Trailer Seat Positioning for Stable Passenger Load Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multipurpose trailers face challenges in providing improved safety and ease of use, particularly in adapting to different numbers of passengers and ensuring stable load distribution during various activities.
Innovation Solution
A multipurpose trailer design featuring removable seats that can be securely attached in multiple transverse positions, with upper and lower seat attachments integrated into the sheet element, allowing for adjustable weight distribution and easy attachment/removal, and a method for securing these seats using straps and connectors to enhance safety and usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the trailer is designed with fixed seats, then the structural stability is improved, but the adaptability for different numbers of passengers deteriorates
Solution Approach 1:
The seat is divided into a removable seat portion and a base structure with attachment points. The seat portion can be detached and reattached at different transverse positions (central or lateral) on the trailer, allowing the structure to be segmented and reconfigured based on passenger needs while maintaining structural integrity through the attachment system.
Solution Approach 2:
The seat configuration transitions from static to dynamic through the removable and repositionable seat design. The seat can be moved between different transverse positions (central for single passenger, lateral for multiple passengers) and easily removed when not needed, enabling the trailer to adapt its configuration based on operational requirements.
2Reliability
If the trailer uses a complex seat attachment system, then the safety is improved, but the ease of operation deteriorates
Solution Approach 1:
The attachment system is segmented into separate upper and lower attachment points that are integrated into the sheet element. This segmentation allows for a straightforward attachment process where the seat simply needs to be positioned and secured at these predefined points, maintaining safety through proper attachment while avoiding complex mechanisms.
Solution Approach 2:
The attachment system is designed to be user-friendly and self-explanatory, allowing users to easily attach and remove seats without requiring complex tools or procedures. The upper and lower attachment points provide clear guidance for proper seat installation, enabling users to safely secure the seat themselves without needing specialized knowledge or equipment.
3Device complexity
If the seat attachments are integrated into the sheet element, then the device complexity is reduced, but the manufacturing precision requirements increase
Solution Approach 1:
The upper and lower seat attachments are merged into a single sheet element structure. This integration reduces the total number of separate components and assembly steps, simplifying the overall device complexity. The sheet element serves multiple functions as both the structural component and the attachment mechanism, eliminating the need for separate attachment hardware.
Solution Approach 2:
The sheet element is designed to serve multiple functions: it provides the structural body of the trailer, incorporates the upper and lower seat attachment points, and enables easy seat installation and removal. This multi-functionality reduces device complexity by eliminating the need for separate dedicated attachment mechanisms while maintaining the required precision through careful design of the integrated attachment features.
