Solution Overview

Problem

Existing securing devices for cargo often require manual knotting and storage, leading to disarrangement and inefficiency when storing straps, which can result in unnecessary wear and tear.

Innovation Solution

A securing device equipped with magnetic members that allow the strap to be rolled up and held in a specific storage position using a magnetic field, preventing knots and disorder, and enabling secure attachment to objects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If manual knotting is used to store the strap, then the strap can be stored without additional devices, but the user has to spend time on disarrangement and the strap may become tangled and worn

Engineering Contradiction:

Improvetime for disarrangementVSAvoidease of storage

Core Design Contradiction:

Loss of timeVSEase of operation

Solution Approach 1:

The patent replaces the manual mechanical knotting system with a magnetic field-based holding system. Magnetic members are attached to the strap at specific positions to create a magnetic field that automatically holds the strap in a rolled-up state without requiring manual intervention or additional storage devices.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The strap becomes self-holding through the magnetic field generated by the magnetic members. The magnetic attraction force automatically maintains the strap in its stored position without requiring external support or manual adjustment, enabling the strap to service itself during storage.

Inventive Principle:

Principle #25Self-service

2Ease of operation

If the strap is stored loosely without magnetic members, then the storage device is simple, but the strap becomes tangled and requires time-consuming disarrangement

Engineering Contradiction:

Improveease of storageVSAvoidtime for disarrangement

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The magnetic members are pre-attached to the strap during manufacturing, so that the strap is already equipped with the capability to hold itself in a rolled-up state. This preliminary preparation eliminates the need for manual knotting or additional storage devices during actual storage operations.

Inventive Principle:

Principle #10Preliminary action

3Stability of the object's composition

If magnetic members are added to the strap, then the strap can be held in a specific storage position, but the device complexity increases

Engineering Contradiction:

Improvestability of rolled-up positionVSAvoidcomplexity of securing device

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent extracts the essential function of holding the strap in a rolled-up state from complex mechanical storage devices and implements it directly on the strap itself through magnetic members. This separates the holding function from external storage mechanisms and integrates it into the strap structure.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent changes the physical state of the strap from a passive flexible material to an active self-holding structure by introducing magnetic properties through the magnetic members. This parameter change enables the strap to generate its own holding force through magnetic field interaction.

Inventive Principle:

Principle #35Parameter changes
