Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for carrying packages, such as plastic and cloth bags, are inadequate in terms of protection, capacity, and environmental sustainability, particularly for larger or heavier items.
Innovation Solution
A cargo carrying device with a polyhedron cargo compartment formed by interconnected panels, equipped with rigid handles and adjustable support straps for enhanced strength and ease of handling, allowing for safer and more efficient transport of various types of cargo.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If plastic bags are used to carry packages, then convenience is improved, but protection and environmental sustainability deteriorate
Solution Approach 1:
The carrying device is divided into multiple rigid panels (front, back, sides, bottom) that form a structured compartment, providing both convenience and protection unlike a single flexible plastic bag
Solution Approach 2:
The device combines multiple rigid panel materials to create a composite structure that offers superior protection while maintaining ease of use, resolving the contradiction between convenience and reliability
2Reliability
If cloth tote bags are used to carry packages, then environmental sustainability is improved, but capacity and protection deteriorate
Solution Approach 1:
The rigid panel structure creates defined walls and compartments that maximize space utilization and provide structural support for heavy loads, enabling greater capacity while maintaining environmental sustainability through reusability
Solution Approach 2:
The collapsible nature of the rigid panels allows the device to be compact when empty for easy storage, yet expand to provide large capacity when needed, while remaining reusable and environmentally friendly
3Reliability
If rigid panel structure is used, then protection and capacity are improved, but device complexity increases
Solution Approach 1:
By dividing the structure into standardized rigid panels that connect at edges, the design achieves strong protection while keeping assembly simple through repetitive modular units
Solution Approach 2:
Multiple panels are merged to form a complete carrying device, where the simple connection method between panels allows complex protective structures to be built from simple components
4Ease of operation
If support straps and rigid handles are added, then ease of handling is improved, but device complexity increases
Solution Approach 1:
The support straps and rigid handles serve multiple functions: providing carrying handles, supporting the cargo weight, and stabilizing the panel structure, thereby improving ease of handling without requiring separate components for each function

AI summary
A cargo carrying device is disclosed including a substantially rectangular bottom panel, a substantially rectangular front panel, a substantially rectangular back panel, substantially rectangular first and second side panels. The front panel, the back panel, and the first and second side panels are each connected to the bottom panel. A polyhedron cargo compartment is formed between the front panel, the back panel, the first side panel, the second side panel, and the bottom panel. Packages and/or other items may be loaded into the cargo compartment for transport. The cargo carrying device has at least one rigid handle for carrying. At least one support strap is connected to the first side panel, the bottom panel, and the second side panel. The support strap is also connected to the rigid handle.
