Solution Overview

Problem

Existing active garments face challenges in connecting electrical conductors to power units or control units when the conductors are not accessible on the outside of the garment, particularly when they run between layers of fabric.

Innovation Solution

An electrical connector comprising a male and female rivet element with a neck washer that forms an electrical connection area, allowing reliable contact with conductors between fabric layers, even if they are not accessible on the outside.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If electrical conductors are run between two layers of fabrics to connect power unit to functional components, then the electrical connection can be made internally within the garment structure, but the conductors become inaccessible for connection to electrical terminals on the outside of the garment

Engineering Contradiction:
ImproveFlexibility in conductor routingVSAvoidAccessibility of conductors for connection
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

A connector assembly acts as an intermediary between the internal conductors and external terminals. The connector includes a first element with contact surface for internal conductor connection, and a second element with terminal for external power unit connection, bridging the accessibility gap.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The electrical connection system is divided into separate components: internal conductor connections within the garment layers, intermediate connector elements, and external terminals. This segmentation allows each part to be optimized for its specific function and accessibility requirements.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If electrical terminals are placed on the outside of the outmost layer or inside the innermost layer for easy access, then the power unit can be easily connected, but the electrical conductors must be accessible at those specific locations which limits design flexibility

Engineering Contradiction:
ImproveAccessibility of electrical terminalsVSAvoidFlexibility in conductor positioning
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The connector assembly serves as a mediator that decouples the location of external terminals from the position of internal conductors. The first element contacts the conductor at its location within the fabric layers, while the second element provides the terminal at an externally accessible position.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The connection system extends across multiple dimensions - from the internal layer structure where conductors are embedded, through the connector assembly that bridges layers, to the external surface where terminals are accessible. This multi-dimensional approach allows independent optimization of each location.

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

3Ease of operation

If a special connection solution is created to connect conductors between fabric layers to external terminals, then conductor accessibility is improved, but the assembly process becomes more complex and may compromise durability

Engineering Contradiction:
ImproveAccessibility of conductorsVSAvoidComplexity of assembly process
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The connector assembly merges multiple functions into a single integrated component: mechanical fastening of fabric layers, electrical contact with internal conductors, and provision of external terminals. This consolidation simplifies the overall assembly process compared to separate connection mechanisms.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The connector assembly is designed as a universal component that can accommodate different conductor configurations and garment structures. The first element can contact conductors in various positions within the fabric layers, while the second element provides a standardized external terminal interface.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

An electrical connector comprises a male element (1) and a female element (2) configured to form a rivet for fastening the electrical connector to a piece of material (10); and a neck washer (30), which has a washer portion (31) and a neck portion (32) and which is configured to be placed between the male element (1) and the female element (2) of the rivet. The washer portion (31) is configured to form an electrical connection area for an electrical conductor (11) of the piece of textile and the neck portion (32) is configured to electrically connect the washer portion (32) to at least one of the male element (1) and the female element (2). The electrical connector can be used independently of the position of the electrical conductor in relation to one or more layers of materials in the piece of material.
