Removable Underside Wheel Mounting for Board Bags
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing board bags with wheels struggle to fit in overhead compartments of smaller airplanes and suffer from wear and tear due to wheel placement, with larger wheels offering limited benefits and reducing internal space.
Innovation Solution
The board bag features wheels with individual bases that are slidably connectable and removable from mounts on the bag's underside, allowing for easy installation and removal, and providing greater ground clearance by mounting wheels completely at the underside.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wheels are mounted on the corners of the board bag, then the board bag can be easily transported, but the bottom of the board bag drags on the ground and is subjected to wear and tear
Solution Approach 1:
The wheels are relocated from the corner positions to the underside of the board bag, changing the spatial dimension of wheel placement. This dimensional shift allows the bottom edge to clear the ground completely during movement, eliminating drag and wear while preserving the rolling function for easy transportation.
2Length of stationary object
If larger wheels are used to increase ground clearance, then the board bag can clear the ground better, but the inner space of the board bag is reduced
Solution Approach 1:
Instead of increasing wheel size to improve ground clearance, the invention changes the vertical position of the wheels by mounting them on the underside of the board bag. This dimensional repositioning achieves adequate ground clearance without compromising the internal storage volume, as the wheels are placed outside the main body cavity rather than consuming internal space.
3Stability of the object's composition
If wheels are fixed permanently on the board bag, then the board bag structure is stable, but the wheels cannot be removed for protection during transport
Solution Approach 1:
The wheel mounting system transitions from a static permanent fixation to a dynamic removable connection. The underside mounting position combined with a removable attachment mechanism allows the wheels to be securely fixed during use for stability, yet easily removed when needed for protection or storage, providing adaptability without sacrificing structural integrity.
4Length of stationary object
If wheels are mounted on the underside of the board bag, then ground clearance is improved and the bottom is protected, but the wheels need to be removable and remountable which adds complexity
Solution Approach 1:
The invention places the wheels on the underside of the board bag, utilizing the external surface area below the main body. This dimensional placement naturally provides ground clearance and bottom protection. The removable mounting feature, while adding some complexity, is simplified by the external underside position which allows easy access for attachment and detachment without interfering with the bag's structure or contents.
