Adjustable Grab Bar for Utility Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicles such as UTVs, ATVs, and motor/dirt bikes often have fixed-position grab bars that are not suitable for riders of different heights, limiting comfort and safety when lifting the rear end, and lack sufficient storage space for payload, requiring multiple trips or additional transportation.
Innovation Solution
A selectively adjustable rear grab bar assembly with pivot points and radially spaced attachment points, and a carrying rack with a grid-pattern framework and side supports that can engage existing grab bars, allowing for adjustable height and increased payload capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-position grab bar is used, then the structure is simple and easy to manufacture, but it is not suitable for riders of different heights, reducing ease of operation and safety
Solution Approach 1:
The grab bar assembly incorporates a bracket with multiple radially spaced attachment points and a pivot point, allowing the grab bar to be positioned at different heights and angles. This dynamic configuration enables riders of various heights to adjust the grab bar to their comfort level, resolving the contradiction between adaptability and structural simplicity.
2Ease of operation
If a fixed grab bar is used, then the device complexity is low, but the ease of operation for riders of different heights deteriorates
Solution Approach 1:
The adjustable bracket design with pivot point and multiple attachment locations allows the grab bar to be repositioned according to rider needs, directly improving ease of operation for riders of different heights while maintaining reasonable structural complexity through a modular design.
3Quantity of substance
If existing vehicle storage space is used, then the vehicle structure remains simple, but the payload capacity is insufficient, requiring multiple trips and reducing productivity
Solution Approach 1:
The carrying rack extends the storage capacity into the vertical dimension by mounting above the vehicle bed, utilizing previously unused space. This dimensional expansion significantly increases payload capacity without adding complexity to the vehicle's base structure, as the rack mounts to the existing grab bar assembly.
4Quantity of substance
If a carrying rack is added to increase payload, then the storage capacity improves, but the device complexity and weight increase
Solution Approach 1:
The grab bar assembly serves dual functions: as a safety feature for riders and as a mounting structure for the carrying rack. This multi-functionality allows the rack to be supported by the existing grab bar structure rather than requiring separate support elements, thereby increasing payload capacity while minimizing additional weight.
