Low-Profile Snap Button With Fabric Barrier And Quiet Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional snap buttons are bulky, noisy, and allow water, air, and dirt to enter between fabric layers due to their complex structure and placement, making them unsuitable for certain applications.
Innovation Solution
A low-profile snap button design featuring a cap and socket connected with fabric, where the cap is anchored to the socket by bending prongs around an S-shaped insert, and a stud extending through both fabric layers for secure connection, with optional plastic teeth for quiet operation and air gaps to prevent noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional snap buttons are used with four separate pieces (cap, socket, stud, post), then the snap button provides secure connection, but the snap button becomes bulky and increases weight and size
Solution Approach 1:
The patent combines the cap and socket into a single integrated component, eliminating the need for separate assembly of these parts. This merging reduces the total number of components from four to three, directly addressing the bulkiness issue while maintaining the secure connection function through the integrated cap-socket design that includes fabric integration features.
2Strength
If traditional snap buttons are used with four separate pieces, then the snap button provides secure connection, but the snap button structure becomes complex and cumbersome
Solution Approach 1:
The integration of cap and socket into one component simplifies the overall structure by reducing the number of parts that need to be manufactured, stored, and assembled. The fabric is incorporated directly into this integrated component, further streamlining the design and reducing structural complexity while maintaining connection security.
Solution Approach 2:
The invention segments the snap button system into three distinct functional components: the integrated cap-socket assembly, the stud, and the fabric layer. This segmentation approach organizes the components more efficiently, making the overall system less cumbersome and easier to manufacture compared to the traditional four-piece design.
3Strength
If the snap button connection is situated between two layers of fabric, then the connection is secure, but water, air and dirt can enter the connection area
Solution Approach 1:
The fabric layer serves as an intermediary element that is integrated directly into the cap-socket assembly. This fabric intermediary creates a barrier that prevents water, air, and dirt from reaching the connection area between the cap and socket, while still allowing the mechanical connection function to operate securely.
4Strength
If traditional metal snaps are used, then the snap button provides strong connection, but the snap button creates noise during engagement and disengagement
Solution Approach 1:
The invention uses composite materials by combining metal (for the integrated cap-socket providing structural strength and connection security) with fabric (for cushioning and noise reduction). This composite approach maintains the strong connection capability of metal while the fabric elements absorb impact and reduce the noisy clicking sound characteristic of traditional metal snaps.
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
The design results in a compact, quiet, and secure snap button that prevents water and air infiltration, enhancing the functionality and aesthetics of connected articles.
Implementation Method 1
The flange has a plurality of interruptions therein so that the flange can be bent outward during assembly... the flange bends around the annular insert to anchor the cap to the socket
Implementation Method 2
The plastic also flexes under pressure and allows the stud to be inserted

AI summary
A snap button has a female portion formed from a cap and a socket that are connected together with a piece of fabric in between. The cap is formed from a base body having a circumferential flange with interruptions therein so that the flange can be bent outward during assembly. The socket is formed by a disc having a central aperture and a peripheral rim, as well as an annular insert disposed within the socket. The cap is connected to the socket by pressing the socket onto the cap until the flange bends around the annular insert to anchor the cap to the socket with the fabric trapped between. A male portion having a stud is connected to the female portion by snapping the stud into the socket such that the stud extends entirely through the socket and into the cap.
