Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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.
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
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.
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.
3Reliability
If complex manufacturing processes are used to achieve precise stem and joint geometry, then adhesion reliability is improved, but production cost increases
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.

Function Achieved in This Case
This solution provides improved adhesion and sealing capabilities, allowing the fastener to withstand higher vibration and impact forces without detachment, and enables cost-effective production through advanced manufacturing techniques, such as micro-replication and droplet application methods.
Implementation Method 1
the pertinent orders of magnitude, which can also be in the nanometer range in preferred configurations, enable an interaction with a corresponding body in the environment on which the fastener part is to be fixed via the so-called adhesion can be viewed
Implementation Method 2
The second articulated part in the area of the foot part forms a damping element opposite the carrier part, which relieves the first articulated part in the area of the head part

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.
