Solution Overview

Problem

Existing adhesive fastener systems face challenges in achieving improved adhesion and sealing while being cost-effective and reliable, particularly under vibrations and impact forces, and require more efficient manufacturing processes.

Innovation Solution

The touch-and-close fastener part features a stem part with a regular or irregular rotation ellipsoid outer contour, a damping element opposite the carrier part, and a double-jointed arrangement that allows for enhanced adhesion and vibration resistance, with a broadened stem part and chemically modified head parts to increase contact surfaces and utilize van der Waals forces for stronger adhesion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the head part is made with a very large diameter to improve adhesion possibility, then adhesion capability is improved, but manufacturing complexity increases due to the need for precise articulation and stem design

Engineering Contradiction:
Improveadhesion capabilityVSAvoidmanufacturing complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The closure part is divided into multiple functional segments: head part, stem part, joint part, and handle part. This segmentation allows each component to be optimized independently - the head part can have large diameter for adhesion while the stem and joint parts manage the complexity of articulation and positioning separately.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The joint part enables dynamic articulation between the handle part and head part, allowing the head part to incline within a definable range. This dynamic capability maintains adhesion effectiveness even when the carrier part is displaced or when vibrations occur, resolving the conflict between large head diameter and manufacturing complexity.

Inventive Principle:
Principle #15Dynamics

2Stability of the object's composition

If the carrier part is made rigid to maintain positioning, then positioning stability is improved, but resistance to vibration and impact forces deteriorates

Engineering Contradiction:
Improvepositioning stabilityVSAvoidvibration resistance
Core Design Contradiction:
Stability of the object's compositionVSReliability

Solution Approach 1:

The articulated joint part between handle and head allows the closure part to dynamically adjust to vibrations and impact forces while maintaining adhesion. The handle part can incline within a definable range, absorbing mechanical shocks without compromising the head part's connection to the body.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The stem part is designed with specific geometric contours that provide inherent cushioning against vibration and impact forces before these forces reach the adhesive connection point, protecting the adhesion from detachment while maintaining overall positioning stability.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

3Reliability

If complex manufacturing processes are used to achieve precise stem and joint geometry, then adhesion reliability is improved, but production cost increases

Engineering Contradiction:
Improveadhesion reliabilityVSAvoidproduction cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The stem part is designed with rotation ellipsoid outer contours and spherical joint surfaces, which can be manufactured using standard spherical milling or turning processes. This geometric approach achieves the required precision for reliable articulation and adhesion while remaining compatible with conventional manufacturing methods, reducing production costs.

Inventive Principle:
Principle #14Spheroidality (Curvature)

AI summary

The invention relates to a closure component having a plurality of closure components (12) each disposed on a carrier part (10) by means of a footer (18) and each comprising a header (14) connected to the footer (18) by means of a shaft part (16), wherein the header (14) is jointedly connected to the shaft part (16) by means of a hinge part (20). Because the footer (18) forms a further hinge part (22), by means of which the shaft part (16) is jointedly connected to the carrier part (10), improved adhesion to third components can be produced relative to the known solutions.
