Rotatable Handle for Luggage Attachment System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for attaching carry bags or luggage to handle systems or wheeled carts are cumbersome and pose safety risks due to the use of elastic ties that require strategic placement and can accidentally release, leading to injuries.
Innovation Solution
A rotatable handle system is designed to be resiliently attached to a carry bag, allowing it to rotate between a storage position and an attaching position, facilitating secure engagement with upright support members of another carry bag or wheeled cart using bungee cords or straps, with a gripping handle and optional pouch for easy manipulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If elastic ties with hooks or clips are used to attach a bag to the handle system, then the bag can be attached to the handle system, but the attachment system becomes cumbersome and requires strategic placement of multiple components
Solution Approach 1:
The patent combines multiple attachment components (handle, elastic tie, hooks) into a single integrated attachment device. The handle is directly connected to the elastic tie and hooks, eliminating the need for separate placement of multiple components and simplifying the attachment process while maintaining secure attachment.
Solution Approach 2:
The attachment device is designed to be universally applicable to various bag and cart combinations. The handle can be attached to different types of upright supports, and the elastic tie with hooks can secure to various bag configurations, making the system versatile for multiple attachment scenarios.
2Adaptability or versatility
If expandable cords are used for attachment, then the attachment can be adjusted to different lengths, but the cords can be accidentally released and cause injury
Solution Approach 1:
The patent extracts the dangerous expandable cord function from the attachment system and replaces it with a safer configuration. The elastic tie is contained within the handle structure with internal hooks that engage with the bag, eliminating the risk of accidental release while maintaining length adjustment capability through controlled extension.
Solution Approach 2:
The attachment device incorporates safety features that prevent accidental release before it can cause injury. The hooked ends are designed to engage securely with the bag, and the elastic tie is contained within the handle structure, providing a safety mechanism that prevents the harmful effect of accidental release.
3Reliability
If separate attachment devices are supplied with carry bags, then the bags can be attached to handle systems, but the attachment process becomes cumbersome and time-consuming
Solution Approach 1:
The attachment device is merged with the handle system, becoming an integrated component rather than a separate accessory. The handle is pre-connected to the elastic tie and hooks, allowing users to attach bags in a single motion without handling multiple separate components, significantly reducing attachment time.
4Reliability
If multiple resilient members are used to attach the handle to the carry bag, then the handle attachment becomes more secure, but the device complexity increases
Solution Approach 1:
The attachment system is segmented into functional components (handle, elastic tie, hooks) that work together as an integrated unit. Rather than using multiple separate resilient members, the single elastic tie is strategically positioned and connected to provide secure attachment, reducing complexity while maintaining reliability.
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 system provides a safe and convenient means to attach and detach luggage, eliminating the risks associated with traditional elastic ties and enhancing user safety while allowing for easy handling and transportation of multiple bags as a single unit.
Implementation Method 1
a handle (18) resiliently connected to one wall of the carry bag (20) by at least one resilient member (30, 32)

AI summary
A system for releasably attaching an article of luggage such as a first carry bag, with or without a pair of upright support members, to a second carry bag system or wheeled luggage cart having at least a pair of upright stationary support members is disclosed in which a handle is resiliently attached to the first carry bag, and a device is provided for resiliently attaching the handle to the first carry bag in a manner to permit rotation of the handle between a first storage position between a pair of upright support members of the second carry bag system and a second interference position with the upright support members of the second carry bag system to thereby attach the first carry bag to the upright support members of the second carry bag system. The handle is preferably in the form of a zippered pouch having a planar plate attached thereto for engagement with the upright support members.
