Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle crossbar assemblies do not efficiently transition between installable and storage states, often requiring complex disassembly and lacking compact storage solutions.
Innovation Solution
A vehicle crossbar assembly with movable parts that extend when installed and fold for storage, utilizing a hinged retention structure to pivot between states, allowing for easy conversion between usage and storage configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If crossbar assembly is designed to be easily assembled and disassembled for storage, then ease of operation is improved, but structural strength may deteriorate
Solution Approach 1:
The crossbar assembly is divided into multiple segments (first crossbar portion, second crossbar portion) that can be independently moved and positioned. This segmentation allows the assembly to be disassembled into compact segments for easy storage while maintaining full structural strength when assembled, as each segment retains its load-bearing capability.
Solution Approach 2:
The crossbar assembly incorporates movable connections with retention structures that allow dynamic transition between assembled and disassembled states. The retention structures provide secure engagement during use (maintaining strength) while allowing easy release for storage, creating a dynamic system that adapts between operational and storage configurations.
2Ease of operation
If crossbar assembly uses complex disassembly mechanisms, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The assembly is segmented into distinct portions with simple retention structures at each interface. This segmentation avoids the need for complex centralized disassembly mechanisms, as each segment can be independently engaged or disengaged from its corresponding retention structure through simple movements.
Solution Approach 2:
The retention structures are designed to be dynamically engaged and disengaged through simple movements of the crossbar portions. This dynamic design allows easy transition between states without requiring complex tools or mechanisms, as the retention structures naturally guide the assembly and disassembly process.
3Volume of moving object
If crossbar assembly is designed for compact storage, then space efficiency is improved, but ease of operation worsens
Solution Approach 1:
The crossbar assembly is segmented into portions that can be folded or positioned adjacent to each other for compact storage. This segmentation enables the assembly to be collapsed into a small volume while maintaining simple engagement interfaces that preserve ease of operation during assembly and disassembly.
Solution Approach 2:
The retention structures are designed to work with the dynamic folding motion of the crossbar portions. As the portions are folded into the compact storage configuration, the retention structures naturally guide the movement and secure the folded position, making the compacting process as easy as the assembly process.

AI summary
A vehicle crossbar assembly includes a crossbar. The crossbar has a first part and a second part that are movably attached to each other. The first part is configured to be supported to a first roof rack component of a vehicle. The second part is configured to be supported to a second roof rack component of the vehicle. The first and second parts are movable with respect to each other between an installable state and a storage state. The first and second parts extend from one another when in the installable state. The first and second parts are folded with respect to each other in the storage state.
