Solution Overview

Problem

Existing sequins with electrical or electronic components face challenges in securely and efficiently attaching to textiles while accommodating complex functionalities, particularly when detecting movements with acceleration sensors, due to limitations in thread connection methods that require significant space and may not provide adequate protection against external influences.

Innovation Solution

A sequin design featuring a circuit carrier with conductive areas, including notch-shaped recesses and openings for thread placement, allowing for a compact and secure mechanical and electrical connection, along with an insulating and protective compound to cover the sequin and thread areas for enhanced protection and stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If traditional opening-based thread connection methods are used, then the sequin can be attached to textiles, but the space required is significant and positioning precision is insufficient for complex functional elements

Engineering Contradiction:
Improvepositioning precisionVSAvoidspace requirement
Core Design Contradiction:
Manufacturing precisionVSArea of stationary object

Solution Approach 1:

The connection area is segmented into multiple notches arranged in a circular pattern, allowing the thread to be distributed across multiple contact points rather than requiring a single large opening. This segmentation enables precise positioning while minimizing the total area occupied by the connection structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connection approach transitions from a two-dimensional opening to a three-dimensional notch structure that extends into the substrate. This dimensional change allows the thread to engage with the carrier element through lateral walls and bottom surfaces of the notches, providing enhanced positioning precision within a compact footprint.

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

2Reliability

If multiple openings are used for thread connection, then the sequin can be securely attached, but the complexity of the carrier element increases

Engineering Contradiction:
Improveconnection reliabilityVSAvoidcarrier element complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Multiple notches are arranged in a circular pattern and function together as an integrated connection system. The notches work collectively to secure the thread through distributed contact points, achieving reliable attachment while maintaining a unified structural design that does not significantly increase overall complexity.

Inventive Principle:
Principle #5Merging (Combining)

3Stability of the object's composition

If the carrier element is made rigid for structural stability, then the sequin maintains its shape, but flexibility and wearability on textiles is reduced

Engineering Contradiction:
Improvestructural stabilityVSAvoidflexibility
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The carrier element exhibits local quality variations where the central region maintains rigidity to support functional elements, while the peripheral regions with notches provide flexibility for textile attachment. This spatial differentiation of mechanical properties allows the sequin to simultaneously achieve structural stability and adaptability to curved textile surfaces.

Inventive Principle:
Principle #3Local quality
