Solution Overview

Problem

Individuals wearing flip-flops face the inconvenience of having to carry them by hand or leave them behind while walking barefoot, as traditional flip-flops lack a convenient means for hands-free carrying.

Innovation Solution

A multifunctional carrying strap system with hooks at each end that can securely attach to flip-flops, allowing them to be draped around the body or neck, enabling hands-free carrying.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If flip-flops are carried by hand, then the footwear can be transported, but the individual's hands are tied up and cannot perform other activities

Engineering Contradiction:
Improvehands-free carrying capabilityVSAvoidcarrying system structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The carrying system is divided into separate functional components: a strap material for body attachment, hook mechanisms for footwear attachment, and connection elements. This segmentation allows each component to perform its specific function independently while maintaining overall system simplicity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The strap material serves multiple functions: it acts as both a carrying strap and an attachment mechanism for the hooks. The hooks can attach to various footwear types with straps, making the system universally applicable to different footwear while maintaining a simple overall structure.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If flip-flops are left at a location on the beach, then the individual can walk barefoot freely, but the individual must return to retrieve the flip-flops or risk losing them

Engineering Contradiction:
Improvemobility freedomVSAvoidfootwear security
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The strap material is positioned and sized to distribute the weight of the attached footwear evenly across the body, creating a balanced carrying system that allows free movement without compromising security. The balanced positioning prevents the footwear from swinging or detaching during movement.

Inventive Principle:
Principle #8Anti-weight (Counterweight)

3Adaptability or versatility

If a carrying strap system is added to flip-flops, then hands-free carrying is enabled, but the device complexity increases

Engineering Contradiction:
Improvecarrying functionalityVSAvoidsystem components
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The hook mechanisms are integrated directly with the strap material by attaching the hooks to the ends of the strap. This merging of components eliminates the need for separate attachment devices while maintaining the versatility of hands-free carrying functionality.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A multifunctional carrying strap system includes a strap material that is configured to be worn by an individual. The strap system includes hooks arranged at each end thereof for engaging with footwear such as flip-flops. The strap system includes a first hook that selectively engages with a strap portion of one of the flip-flops, and a second hook that selectively engages with a strap portion of the other one of the flip-flops. In this arrangement, the flip-flops are held by the carrying strap worn by the individual, without requiring the individual to use their hands in carrying the flip-flops. The hands-free arrangement of the multifunctional carrying strap system allows the individual to hold hands with another person, or persons, carry a drink or other object, and/or otherwise enjoy full use of the individual's hands while carrying the flip-flops around their neck via the multifunctional carrying strap system.
