Solution Overview

Problem

Existing snap fasteners are limited to attaching only one or two layers together, failing to provide a solution for connecting multiple layers effectively in various applications.

Innovation Solution

The introduction of a snap jack fastener system that includes a top protruding element with a central cavity and a ring, along with a bottom protruding element featuring a cone-shaped barb or threaded screw, allowing for the secure attachment of multiple layers of fabric or materials through a multifunctional snap system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional snap fasteners are used, then the structure is simple and easy to manufacture, but the capability to attach multiple layers is limited

Engineering Contradiction:

Improvecapability to attach multiple layersVSAvoidsnap fastener structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The snap fastener is divided into distinct functional segments: a top protruding element with central cavity for receiving sockets, a ring for structural support, and a bottom protruding element with piercing member for penetrating fabric. This segmentation allows each component to perform its specific function while collectively enabling multi-layer attachment capability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The snap fastener is designed as a universal component that can attach multiple layers of fabric or material together through its dual protruding elements and central cavity structure. The same fastener can connect different numbers of layers depending on the configuration of sockets and piercing members, providing multi-functional capability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Strength

If traditional snap fasteners are used, then the device is simple to operate, but the connection strength for multiple layers is insufficient

Engineering Contradiction:

Improveconnection strength for multiple layersVSAvoidsnap fastener operation

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

The bottom protruding element is pre-formed with a piercing member that can penetrate fabric layers before the final connection is made. The central cavity is pre-configured to receive sockets, allowing the fastening sequence to proceed efficiently through preliminary positioning and penetration actions.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Sockets serve as intermediary components that connect the top protruding element to the fabric layers. The piercing members act as intermediaries that penetrate through multiple fabric layers to create secure anchor points, enabling strong connections while maintaining operational simplicity.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A fastener element used to couple one or more items together, including layers of fabrics or other materials. The fastener element includes a top element having a central opening with a closed bottom surface adjoining a ring. On an underside of the ring is a protruding, piercing element that. The fastener element allows for more than two layers to be fastened together in a snap system and for a plurality of layers to be joined together. The fastener element can allow multiple layers to be joined together by coupling a first socket of a snap system to the top element and another socket to an underside of the ring and to the protruding piercing element. The fastener element can be used for multiple applications to secure more than one layer of fabric or another material together.
