Universal Coupling Mechanism for Functional Shoe Attachments

Solution Overview

Problem

Existing functional shoes require multiple incompatible functional devices for different functions, leading to high manufacturing costs and reduced efficiency due to the need for individual coupling members for each device.

Innovation Solution

A functional shoe design that includes a sole, a functional part, a fixing part, and a coupling part, where the fixing part has a leg member that inserts into a coupling part with an insertion slot, allowing for compatibility and easy coupling/decoupling of various functional devices, such as roller skates, anti-slip, or spring functions, using a common coupling member.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple individual functional devices are used for different functions, then various specific functions can be provided to the shoes, but manufacturing costs increase and compatibility is reduced

Engineering Contradiction:

Improvefunctional versatilityVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The coupling part is designed as a universal interface that can accommodate multiple different functional devices through a single standardized connection mechanism. The coupling part includes a coupling body with an insertion slot and a coupling member that can interface with various functional parts (such as skating devices, climbing irons, or other attachments), allowing one shoe structure to support multiple functions without requiring separate coupling mechanisms for each function.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The fixing part and coupling part are merged into an integrated assembly that combines the fastening function (fixing part with fastening member) and the interface function (coupling part with insertion slot). This merging reduces the total number of separate components needed, as the same structural elements serve dual purposes: securing the functional device to the shoe while also providing a standardized interface for compatibility.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A functional shoe includes a sole, a functional part to provide a specific function to the functional shoe, a fixing part provided to fix the functional part; and a coupling part provided to be coupled to the fixing part, and directly or indirectly coupled to the sole, at an opposite side to a side coupled to the fixing part. The fixing part includes a fixing body provided to be coupled to the functional part, and a leg member formed to extend from the fixing body in a reference direction which is a direction facing the sole from the fixing body. The coupling part includes an insertion slot provided inside the coupling part to be open in a direction opposite to the reference direction such that the leg member is inserted into the insertion slot.
