Wearable Vest Attachment Device for Hands-Free Bag Carrying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing attachment devices do not provide a hands-free solution for carrying bags, as they lack a vest with attached hooks to engage handle straps, limiting the convenience of carrying various types of bags.
Innovation Solution
A vest with a plurality of hooks is designed to attach to handle straps of bags, allowing users to carry bags and their contents without using their hands, featuring a water-impermeable material, closure options, and a harness for distributing weight across the torso.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing attachment devices (straps with hooks, clips, or support arms) are used, then bags can be attached to the user, but the user cannot carry bags hands-free as the devices lack a vest structure with multiple hooks
Solution Approach 1:
The vest is designed with multiple hooks distributed across the torso, allowing it to attach various types of bags (shopping bags, purses, backpacks) with different handle configurations. The harness system can accommodate different bag weights and positions, making the device universally applicable to multiple bag types while enabling hands-free carrying.
Solution Approach 2:
The attachment device is segmented into multiple independent hooks rather than a single attachment point. This segmentation allows different hooks to engage with different handle straps of the same bag or multiple bags simultaneously, providing flexibility in attachment configurations and enabling hands-free carrying for various bag styles.
2Ease of operation
If a vest with multiple hooks is implemented, then hands-free carrying of various bags is enabled, but the device complexity increases compared to simple straps or clips
Solution Approach 1:
The vest with multiple hooks is designed to be self-adjusting and self-configuring. Users can independently position and attach bags to different hooks based on their needs without requiring complex adjustment mechanisms. The harness system naturally distributes weight and accommodates different body sizes through simple wearability, reducing the need for complex regulatory mechanisms.

AI summary
A user worn attachment device for engaging handle straps of bags to allow for hands free carrying of the bags includes a vest, which can be donned by a user. A plurality of hooks is attached to the vest, with each hook being selectively attachable to one or more handle straps of a bag. The bag and its contents thus are attached to the vest and carriable by the user without using their hands.
