Linked Protective Bag Assembly With Locking Leg Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bags fail to provide reliable protection for personal items and professional equipment during travel, especially under tough conditions, and do not facilitate easy and stable transport of multiple bags simultaneously.
Innovation Solution
The bags are designed with protective covers, handle assemblies, and connector systems that allow bags to be linked together, forming a self-stabilizing assembly for easy transport, and include features like retractable handles and wheels for enhanced maneuverability and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bags are designed with protective covers and connector systems to shield contents and enable linking, then protection reliability and transport stability are improved, but device complexity increases
Solution Approach 1:
The bag is divided into modular components including a body, protective cover, handle assembly, and connector assembly. Each component serves a specific function and can be independently manufactured and assembled, allowing the complex protective and linking features to be implemented through standardized modules rather than integrated complex structures.
Solution Approach 2:
The handle assembly is positioned between the protective cover and the back surface of the bag, creating a nested configuration where the handle is partially enclosed by the protective cover. This nesting arrangement protects the handle mechanism while integrating it into the overall bag structure without adding external complexity.
2Stability of the object's composition
If multiple bags are linked together to form a self-stabilizing assembly, then transport stability is improved, but ease of operation decreases
Solution Approach 1:
The connector assembly includes fastening mechanisms that enable users to easily link and unlink bags through simple operations. The self-stabilizing assembly automatically maintains its configuration when bags are connected, reducing the need for manual adjustment and making the system easy to operate while maintaining stability.
3Object-affected harmful factors
If handle assemblies are positioned between protective cover and back surface for retraction, then protection is improved, but ease of operation worsens
Solution Approach 1:
The handle assembly is nested within the space between the protective cover and the back surface of the bag. This positioning allows the handle to be retracted into a protected position when not in use, shielding it from physical impacts, while still being accessible when needed for maneuvering the bag.

AI summary
A bag comprising a body; a shell; a leg assembly comprising a first leg pivotably coupled to a first portion of the shell, a second leg pivotably coupled to a second portion of the shell, and a cross member extending between the first leg and the second leg; and a handle assembly comprising a handle and a first member pivotably coupled to a third portion of the shell; an engagement feature that is attached to or integrated with the handle; and a second member connecting the first member to the cross member, wherein the second member is configured to receive the engagement feature in order to lock the plurality of legs in an extended position.
