Solution Overview

Problem

Conventional hook and loop fasteners face issues such as fluff and textile threads getting stuck, reduced adhesion, hygiene problems, loose connections due to vibration, limited material options, complex manufacturing, and sharp edges leading to injuries.

Innovation Solution

A nub grid connection system with triple or quadruple segmented rotary bodies and conical sliding surfaces, arranged in a rectangular or hexagonal grid, allowing self-positioning interlocking without a base plate, enabling force transfer in multiple directions and easy release.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If hook and loop fasteners are used, then connection is achieved, but fluff and textile threads get stuck leading to reduced adhesion

Engineering Contradiction:

ImproveadhesionVSAvoidfluff accumulation

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The nubs are designed as triple or quadruple segmented rotary bodies with conical sliding surfaces. This segmentation allows the connection surfaces to interlock through geometric merging of the segmented bodies rather than through hook-loop entanglement, preventing fluff and textile threads from getting stuck while maintaining reliable adhesion.

Inventive Principle:

Principle #1Segmentation

2Force

If Velcro fasteners are used for tool holders, then connection is achieved, but power transmission effectiveness is reduced due to elastic connection

Engineering Contradiction:

Improvepower transmissionVSAvoidconnection rigidity

Core Design Contradiction:

ForceVSStability of the object's composition

Solution Approach 1:

The nubs feature conical sliding surfaces that enable self-positioning and form-fitting interlocking when connection surfaces are pressed together. This geometric design provides rigid, non-elastic connection that effectively transmits power and force, eliminating the elastic deformation characteristic of Velcro fasteners.

Inventive Principle:

Principle #14Spheroidality (Curvature)

3Strength

If METAKLETT system is used, then connection strength is improved, but precise positioning is required and sharp edges can cause injuries

Engineering Contradiction:

Improveconnection strengthVSAvoidpositioning requirement

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

The conical sliding surfaces on the segmented rotary bodies enable self-positioning of the connection surfaces. When the surfaces are pressed together, the geometry automatically guides proper alignment without requiring precise pre-positioning by the user, while the rounded conical surfaces eliminate sharp edges that could cause injuries.

Inventive Principle:

Principle #25Self-service

4Reliability

If conventional fasteners are used, then connection is achieved, but manufacturing complexity increases

Engineering Contradiction:

Improveconnection reliabilityVSAvoidmanufacturing complexity

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The invention combines multiple functions into a single geometric feature: the triple or quadruple segmented rotary bodies with conical sliding surfaces simultaneously provide self-positioning, form-fitting interlocking, and reliable connection. This integrated design eliminates the need for separate positioning mechanisms and base plates, simplifying manufacturing while maintaining connection reliability.

Inventive Principle:

Principle #5Merging (Combining)
