Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional snap-type fasteners are used to securely attach articles, then reliable coupling is achieved, but significant protrusion from the article surface occurs, compromising aesthetics and functionality

Engineering Contradiction:
Improvecoupling reliabilityVSAvoidprotrusion height
Core Design Contradiction:
ReliabilityVSLength of stationary object

Solution Approach 1:

The socket component is designed with a cup-shaped structure that receives and nests the stud component within its cavity. When assembled, the stud fits inside the socket's internal space rather than extending outward, creating a nested configuration that minimizes the overall profile height while maintaining secure coupling between fabric layers

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The invention transitions from a conventional protruding fastener design to a low-profile design by optimizing the vertical dimension. The socket component's cup-shaped geometry and the stud's fit within this cavity reduce the fastener's height in the direction perpendicular to the fabric surface, achieving reliable attachment with minimal protrusion

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Shape

If a low-profile socket component design is used to minimize protrusion, then aesthetic appearance is improved, but attachment security may be compromised

Engineering Contradiction:
Improveprofile heightVSAvoidattachment security
Core Design Contradiction:
ShapeVSReliability

Solution Approach 1:

The socket component features a cup-shaped structure with specific local geometries including an opening facing the fabric surface and a cavity that receives the stud. This localized structural design concentrates the attachment function within the socket's internal cavity while keeping the external profile low, maintaining both aesthetic appearance and attachment security

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The stud component is nested within the socket's cavity, with the stud's diameter designed to fit within the socket's internal dimensions. This nesting arrangement ensures secure attachment through the interference fit and geometric interlocking within the cup-shaped structure, while the socket's external dimensions remain minimal for a low-profile appearance

Inventive Principle:
Principle #7Nested doll (Nesting)

3Ease of operation

If a bonding agent is used to secure the socket component between textile layers, then reversible attachment is achieved, but additional manufacturing steps are required

Engineering Contradiction:
Improvereversible attachmentVSAvoidmanufacturing complexity
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

A bonding agent is introduced as an intermediary substance between the socket component and the fabric layers. This bonding agent enables reversible attachment by allowing the socket to be securely bonded during manufacturing yet remain removable under appropriate conditions, facilitating ease of operation while managing manufacturing complexity through a standardized bonding process

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A snap-type fastener arrangement includes various elements. For example, the snap-type fastener arrangement includes a socket component and a stud component. The stud component is insertable into the socket component to releasably couple two items together. The snap-type fastener includes a construction having a relatively low profile that does not extensively protrude outward from the underlying article to which the snap-type fastener is attached. The socket component includes a portion for securing the socket component to a textile layer and a central portion that extends through the textile layer. The stud component may be inserted into a socket aperture in the central portion of the socket in order to mate the two components.
