Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional snap fasteners for knitted fabrics require sewing, gluing, or crimping, which can damage the fabric, are aesthetically unpleasing, and need specialized skills for secure attachment, and often cause wear and tear during disassembly.

Innovation Solution

A snap receiver system that attaches to fabric without sewing or adhesive, using a snap post assembly with a retainer assembly and lock ring, allowing secure retention and easy release with minimal force, reducing stress on the fabric and eliminating the need for specialized skills.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional methods (sewing, gluing, crimping) are used to attach snap fasteners to knitted fabrics, then secure attachment is achieved, but fabric damage and aesthetic degradation occur

Engineering Contradiction:

Improveattachment securityVSAvoidfabric damage

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an intermediary mechanism (the snap receiver with lock legs and lock ring) that mediates between the snap fastener and the fabric. Instead of directly attaching the snap to the fabric through harmful methods, the lock legs pass through the fabric and are secured by the lock ring, distributing stress and avoiding direct damage to fabric fibers while maintaining secure attachment

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If sewing or specialized attachment methods are used, then secure fastening is achieved, but specialized skills and tools are required

Engineering Contradiction:

Improveattachment securityVSAvoidattachment complexity

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The snap receiver is designed to be self-securing through its own components. The lock legs pass through the fabric and are locked in place by the lock ring through a simple rotational motion, eliminating the need for external sewing tools or specialized skills. The device performs its own attachment function without requiring external intervention or expertise

Inventive Principle:

Principle #25Self-service

3Productivity

If conventional snap fasteners are repeatedly assembled and disassembled, then fastening function is maintained, but wear and tear increases

Engineering Contradiction:

Improvefastening speedVSAvoidfastener lifespan

Core Design Contradiction:

ProductivityVSDuration of action of stationary object

Solution Approach 1:

The lock ring and lock legs are designed to absorb and distribute the mechanical stress of repeated assembly and disassembly operations. The lock ring's rotational locking mechanism provides a cushioning effect that protects the fabric and fastener components from excessive wear, allowing the fastener to withstand numerous cycles of use without degradation

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

AI summary

Techniques for a snap receiver are provided. In an example, a snap receiver can include a snap receiver base, and a lock ring. The snap receiver base can include a first opening in a first major surface, the first opening configured to first receive a snap post, and a plurality of lock legs extending from a second major surface. The lock ring can include a plurality of irregular slots, configured to secure the snap receiver to a fabric. A distal end of each lock leg can be configured to pass through the fabric and through a first end of a respective slot of the plurality of irregular slots. A first rotation of the lock ring with respect to the snap receiver base can lock a distal end of each of the lock legs within a second end of the respective slot of the plurality of irregular slots.
