Solution Overview

Problem

Existing portable pocket attachment systems for fabric objects are insecure, prone to detachment, and can damage fabrics, often requiring permanent modifications or specialized tools, and are not versatile enough to attach to various locations or fabric types.

Innovation Solution

A removable attachment system comprising an outer and inner part with mating fasteners that compress the fabric to secure a portable pocket, allowing quick and easy attachment and removal without altering the host object, suitable for various fabric types and pocket configurations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If removable adhesive or hook and pile fastener is used to attach portable pocket, then attachment is achieved, but holding strength is lost with repeated use and detachment is easy

Engineering Contradiction:

Improveattachment securityVSAvoidholding strength

Core Design Contradiction:

ReliabilityVSStrength

Solution Approach 1:

The attachment system is divided into two separate parts: an outer part that attaches to the host fabric and an inner part that receives the portable pocket. This segmentation allows each part to be optimized independently and enables secure attachment through the interaction between the two parts via compression fasteners.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The attachment system uses compression fasteners that can be dynamically adjusted. The fasteners compress the host fabric between the outer and inner parts, creating a secure attachment that can be easily released by applying force in the normal direction, providing both security and ease of detachment.

Inventive Principle:

Principle #15Dynamics

2Reliability

If removable adhesive is used to attach portable pocket, then attachment is achieved, but fabric damage occurs upon removal

Engineering Contradiction:

Improveattachment securityVSAvoidfabric damage

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The invention replaces the chemical adhesive system with a mechanical compression fastening system. The outer part and inner part compress the host fabric mechanically between them, eliminating the need for adhesives that can damage fabric upon removal.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The host fabric acts as an intermediary element between the outer part and inner part. The fabric is compressed between these two parts to create the attachment, rather than being bonded chemically, allowing for damage-free removal.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If clips, straps, snaps or similar fasteners are used to attach portable pocket, then secure attachment is achieved, but attachment is limited to specific locations or requires permanent modification

Engineering Contradiction:

Improveattachment securityVSAvoidattachment location flexibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The attachment system is designed to be universal and can be attached to any location on any fabric object. The outer part can be positioned anywhere on the host fabric, and the compression fastening mechanism works with various fabric types and thicknesses, providing versatile attachment without requiring permanent modification.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system can accommodate various pocket configurations and fabric types by adjusting the dimensions and parameters of the outer and inner parts. The variable configurations allow the pocket to be attached to various types and thicknesses of fabric at any location.

Inventive Principle:

Principle #35Parameter changes

4Reliability

If magnet-based attachment system is used, then secure attachment is achieved, but interference with electronic devices occurs

Engineering Contradiction:

Improveattachment securityVSAvoidelectronic device interference

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The invention extracts the magnetic field from the attachment system entirely. Instead of using magnets to achieve secure attachment, the system uses mechanical compression fasteners that compress the fabric between two parts, eliminating the harmful electromagnetic interference while maintaining attachment security.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

A removable attachment system for temporarily attaching a portable pocket to an object made of fabric such as clothing, bag, or the like. The system comprises an outer part placed on the front side of the host fabric and an inner part placed on the back side of the host fabric in a manner such that the host fabric is compressed between the two parts thereby securing the two parts in place. The portable pocket being bound to the outer part is thereby quickly and easily attached to any location on the host object requiring no temporary or permanent modification to the host object and affecting no permanent alteration to the host object upon removal of the portable pocket.
