Solution Overview

Problem

Existing cargo carrying systems fail to efficiently and safely handle large or odd-shaped boxes and cases lacking handholds or suitable openings, often requiring multiple persons to lift and carry due to awkwardness and instability.

Innovation Solution

A cargo carrying strap system comprising a handle assembly, vertical and horizontal straps with releasable connectors, and fasteners for secure attachment and detachment, allowing easy wrapping around cargo perimeters for balanced lifting and carrying.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional carrying methods are used for large or odd-shaped boxes, then the cargo can be transported, but multiple persons are required and carrying becomes awkward and difficult

Engineering Contradiction:

Improveease of carryingVSAvoidnumber of handlers

Core Design Contradiction:

Ease of operationVSQuantity of substance

Solution Approach 1:

The strap system divides the cargo securing function into separate components: vertical straps for wrapping around the cargo, horizontal straps for additional stabilization, and a handle assembly for lifting. This segmentation allows each component to perform its specific function efficiently, enabling single-person operation while maintaining secure cargo attachment

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The strap system acts as an intermediary between the handler and the cargo. Instead of directly grasping awkward boxes without handholds, the user grasps the handle assembly which is connected to the cargo through straps. This intermediary mechanism transforms the carrying task into a manageable operation for one person

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If straps are made easily attachable and detachable, then operation becomes simpler, but connection reliability may be compromised

Engineering Contradiction:

Improveease of attachment and detachmentVSAvoidconnection security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The strap system employs dynamic fastening mechanisms that transition between locked and unlocked states. The fasteners can be easily engaged and disengaged by hand, providing simple operation, while in the locked state they maintain secure connection through mechanical interlocking that prevents accidental detachment during cargo handling

Inventive Principle:

Principle #15Dynamics

3Reliability

If straps wrap tightly around cargo for secure holding, then cargo stability improves, but adjusting and detaching becomes more difficult

Engineering Contradiction:

Improvecargo stabilityVSAvoidease of detachment

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The fastening system allows the straps to maintain tight wrapping around the cargo for stability while enabling easy release when needed. The mechanical fasteners are designed to hold the strap under tension securely, yet can be quickly opened by hand to release the cargo without requiring tools or excessive force

Inventive Principle:

Principle #15Dynamics

AI summary

A cargo carrying strap system is discussed, the strap system having a handle assembly and one or more vertical straps for wrapping around a vertical perimeter of a piece of cargo. The strap system can further include a perimeter strap for wrapping around an edge perimeter of the cargo and a horizontal strap for wrapping around a horizontal perimeter of the cargo.
