Innovation Solution
A shoe carrying device with an upper frame, spring-loaded members, and a handle, allowing secure attachment to shoes and easy transport using a single hand, with optional attachment to a backpack.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If shoes are carried using hands, then hands are occupied and carrying is cumbersome, but this is the simplest method requiring no additional devices
Solution Approach 1:
The patent introduces a shoe carrying device as an intermediary tool between the user and the shoes. This device includes a frame with retaining portions that secure to the shoes, allowing hands-free carrying while eliminating the cumbersome nature of direct hand carrying.
Solution Approach 2:
The shoe carrying device is designed to be self-securing through spring-loaded retaining portions that automatically grip the shoes when inserted, eliminating the need for complex fastening mechanisms or manual adjustment during carrying.
2Ease of operation
If shoes are stored within a backpack or bag, then hands are freed, but shoes occupy valuable space and cause unpleasant odors
Solution Approach 1:
Instead of storing shoes inside the backpack (internal space), the carrying device attaches to the exterior of the backpack using a cord. This moves the shoes from the internal three-dimensional storage space to the external surface, freeing up valuable interior space and preventing odor accumulation inside the bag.
3Ease of operation
If shoe laces or cords are used to fasten shoes to the exterior of a backpack, then hands are freed and space is saved, but repeatedly fastening and unfastening is time-consuming and difficult
Solution Approach 1:
The patent introduces a specialized retaining mechanism as an intermediary between the cord and the shoe. The spring-loaded retaining portions with grips provide automatic securing when the cord is attached, eliminating the need for manual tying or complex fastening operations that consume time.
Solution Approach 2:
The spring-loaded retaining portions automatically engage with the shoes when the device is assembled, providing self-securing functionality. This eliminates the need for repeated manual fastening and unfastening operations, significantly reducing the time and effort required.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates easy and secure transport of shoes, reducing odor issues and space occupation, while providing universal compatibility with various shoe styles.
Implementation Method 1
A first spring is positioned between the lower left member and a first member, and a second spring is positioned between the lower right member and a second member. The first spring and the second spring enable the length of between the upper frame and the first and second shoe retaining portions to extend and retract based on the height of the left and right shoes.
Implementation Method 2
The first spring and the second spring enable the distance between the first member and the second member increase or decrease based on the size of the first shoe and the second shoe.
Implementation Method 3
The first finger grip and the second finger grip provide a comfortable contact point and increase friction between the user's grasp and the upper frame.
Implementation Method 4
The first and the second set of shoe grips increase friction between the left and the right shoes and the first and the second members.

AI summary
A shoe carrying device is disclosed, including an upper frame comprising a lower left member and a lower right member. A first spring is positioned between the lower left member and a first member, and a second spring is positioned between the lower right member and a second member. A first shoe retaining portion extends from the first member and a second shoe retaining member extending from the second member. The first shoe retaining member is configured to be insertable into a left shoe, and the second shoe retaining member is configured to be extended into a right shoe. A handle is connected to the upper frame via a cord, wherein the handle enables the user to carry the shoe carrying device.
