Suitcase Pull Rod With Integrated Beverage Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suitcases with pull rods are inconvenient for users to hold beverages or coffee cups while traveling, as they can collide with the holder or require bending down to access them, leading to forgetfulness and limited capacity due to space constraints.
Innovation Solution
A pull rod design with a handle assembly and supporting member that includes a storage space between handles, accommodating items like bottles or cups, and adjustable telescopic rods for enhanced usability and capacity without increasing the suitcase's size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a holder is provided on the side of the suitcase or pull rod to accommodate bottles or cups, then the capacity to carry beverages is improved, but the user's legs are easy to collide with the holder, reducing ease of operation
Solution Approach 1:
The patent transitions the holder from a side-mounted configuration (horizontal dimension) to a top-mounted configuration on the pull rod (vertical dimension). This dimensional change allows beverages to be carried without obstructing the user's legs during movement, resolving the contradiction between carrying capacity and ease of operation.
Solution Approach 2:
The pull rod serves as an intermediary structure that bridges the gap between the suitcase body and the beverage holder. By mounting the holder on the pull rod rather than directly on the suitcase body, the design creates a elevated platform that eliminates collision between the holder and user's legs while maintaining accessibility.
2Quantity of substance
If the holder is mounted on the side of the suitcase, then the capacity to carry beverages is improved, but the user needs to crouch down to reach the bottle or cup due to height limitation, reducing ease of operation
Solution Approach 1:
The patent elevates the beverage holder from the lower side region of the suitcase to the upper region of the pull rod. This vertical dimensional change positions the beverages at a height that is easily accessible to users without requiring them to crouch down, thus improving ease of operation while maintaining carrying capacity.
3Quantity of substance
If the holder is provided on the side of the pull rod, then the capacity to carry beverages is improved, but the overall size of the suitcase increases, reducing the available capacity for other items
Solution Approach 1:
The patent integrates the beverage holder into the existing pull rod structure, effectively nesting the holder within the spatial envelope of the pull rod assembly. This nesting approach allows the holder to be accommodated within the pull rod's volume rather than adding external protrusions, thereby avoiding an increase in the overall suitcase size while maintaining beverage carrying capacity.
Solution Approach 2:
By mounting the holder on the pull rod in the vertical dimension rather than extending it horizontally from the suitcase body, the design utilizes the pull rod's existing spatial envelope. This dimensional approach allows the holder to be accommodated within the pull rod's volume, avoiding an increase in the overall suitcase footprint while maintaining beverage carrying capacity.

AI summary
A pull rod and a suitcase are provided. The pull rod includes a link assembly, a handle assembly, and a supporting member. The handle assembly is disposed on the link assembly, and the handle assembly includes a first handle and a second handle arranged at intervals along a first preset direction. The supporting member is disposed on the handle assembly, a side of the supporting member facing the link assembly is concave, and a storage space is defined between the supporting member, the first handle and the second handle.
