Wheeled bag with extendable support platform
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wheeled travel bags with integrated support platforms face issues such as restricted laptop screen rotation, inconvenient handle access, and reduced bag capacity due to folding platforms that retract into the interior.
Innovation Solution
A travel bag design featuring a retractable support platform that fits into a depression on the top surface, connected by an adjustable shaft, allowing independent height adjustment without affecting the retractable pull handle, and providing a flat surface for use without reducing bag capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the platform is attached to the pull handle below the top of the pull handle, then the platform provides a working surface, but the laptop screen cannot be rotated beyond 90 degrees due to the presence of the handle
Solution Approach 1:
The patent repositions the platform from being attached to the pull handle to being integrated into the top surface of the bag body, effectively moving the platform to a different spatial dimension. This allows the platform to extend beyond the handle area in the lateral dimension, providing unrestricted laptop screen rotation while maintaining platform stability.
2Ease of operation
If the platform is positioned at the top of the pull handle, then the platform provides a working surface, but the pull handle cannot be grasped while the laptop is in place
Solution Approach 1:
The patent extracts the platform from the pull handle structure and relocates it to the top surface of the bag body. This separation removes the conflict between platform occupancy and handle accessibility, allowing users to grasp the handle freely while laptops remain on the platform without obstruction.
3Volume of stationary object
If the platform folds away into the interior of the bag, then the platform can be retracted, but the retracted platform reduces the space available in the bag
Solution Approach 1:
The patent designs the platform with a nesting structure where the platform panels can be folded into each other and stored within a dedicated recess or compartment on the top surface of the bag. This nesting mechanism allows complete retraction of the platform without encroaching on the bag's interior storage capacity, as the folded platform occupies external space rather than internal space.
4Ease of operation
If the platform folds away into the interior of the bag, then the platform can be retracted, but the bag needs to be partially emptied and opened to access the retracted platform
Solution Approach 1:
The patent extracts the platform storage function from the bag's interior compartments and creates a dedicated external storage location on the top surface. The platform folds into this externally accessible recess, eliminating the need to open bag flaps or empty contents to access the retracted platform, thereby simplifying the access procedure while maintaining platform security.

AI summary
A travel bag assembly that utilizes a bag construct with a top surface. A retractable pull handle is provided. A depression is formed in the top surface of the bag construct. A support platform is provided that either directly fits into the depression or can be folded to fit in the depression. The support platform is connected to the bag construct by at least one adjustable shaft. The adjustable shaft enables the support platform to be selectively adjusted in elevation throughout a range above top surface of the bag construct without effecting the retractable pull handle.
