Nested Luggage Drink Holder Assembly for Stable Cup Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing luggage designs lack a secure and aesthetically integrated drink holder that can be easily extended or collapsed, often requiring separate movement of components and failing to provide adequate vibration support in the extended position, compromising the luggage's appearance when mounted.
Innovation Solution
A combination luggage and drink holder assembly featuring a base frame, hoop, and tray pivotally coupled with links, allowing synchronous movement between extended and received positions, with elastic members and stop blocks for secure positioning against vibration, and a design that hides the base frame when collapsed, ensuring the drink holder is securely attached and visually integrated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a drink holder is mounted on luggage, then the user can hold a beverage without manual holding, but the base frame or pivot connection parts may be visible and compromise the appearance of the luggage
Solution Approach 1:
The drink holder is designed with a nested structure where the hoop contains the base frame when in the received position. The peripheral wall of the hoop surrounds and hides the base frame and pivot connection parts, making them invisible from the outside while maintaining the functional capability of holding beverages
2Adaptability or versatility
If the drink holder components are allowed to move freely between extended and received positions, then the drink holder can be extended for use, but the components may not be securely held in position against vibration
Solution Approach 1:
Elastic members are pre-installed on the base frame to provide preliminary counteracting force against vibration. When the drink holder is in the extended position, the elastic members are positioned to automatically resist and dampen vibrations, securing the components in place without requiring additional active control mechanisms
3Adaptability or versatility
If the tray and cup hoop are designed to move separately, then each component can be independently adjusted, but the user needs to bias them separately which increases operational complexity
Solution Approach 1:
The tray and cup hoop are connected through links that couple their movements together. When the user operates one component, the links transmit the motion to the other component, ensuring they move synchronously as a unified mechanism, thereby simplifying operation while maintaining adjustability
4Shape
If the drink holder is collapsed to attach closely to the luggage, then the appearance is improved, but there are no means to keep the base frame or pivot connection parts from sight
Solution Approach 1:
The hoop is designed with a peripheral wall that completely surrounds the base frame and pivot connection parts when the drink holder is collapsed. This nested configuration ensures that all structural components are hidden within the hoop's perimeter, achieving a clean, integrated appearance without exposing mechanical details
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a secure, aesthetically pleasing, and user-friendly drink holder that can be easily extended or collapsed, ensuring the beverage is held securely against vibrations while maintaining the luggage's appearance, allowing users to carry both luggage and a drink without manual holding.
Implementation Method 1
the rear side of the hoop can be stopped at elastic members at the front side of the base frame to keep the drink holder securely in the extended position

AI summary
A combination luggage and drink holder assembly includes a luggage, and a drink holder pivotally mounted at the luggage and including a base frame, a hoop pivotally coupled to the top side of the base frame, a tray pivotally coupled to the bottom side of the base frame and two links coupled between the hoop and the tray. The base frame has a structure for supporting the hoop and the tray securely in the extended or received position. The hoop defines a locating hole at the center and a peripheral wall around the border. When the drink holder is set in the received position, the peripheral wall of the hoop surrounds the base frame and the tray, and the tray blocks up the locating hole of the hoop.
