Solution Overview

Problem

Existing self-defense solutions, such as flexible cords and chains, are impractical for daily civilian use due to their visibility and inconvenience, lacking a concealed and easily deployable option that does not hinder movement or require fumbling for a weapon.

Innovation Solution

A self-defense garment assembly with a concealed pull cord and cord retaining guide means, allowing the cord to be slidably retained within the garment and quickly accessed via gripping loops at the sleeve ends, enabling rapid deployment for restraining or subduing an opponent without inhibiting the wearer's movement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a flexible cord or chain is carried as a self-defense weapon, then combat effectiveness is improved, but portability and daily usability deteriorate due to visibility and inconvenience

Engineering Contradiction:

Improvecombat effectivenessVSAvoidportability and daily usability

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The self-defense cord is merged with a everyday garment (jacket, coat, or shirt) by integrating cord retaining guide means into the garment structure. The cord is concealed within the garment's sleeves and body, allowing the wearer to carry a functional self-defense weapon while maintaining normal daily appearance and comfort. This combining of defense function with civilian clothing resolves the contradiction between combat effectiveness and portability.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The pull cord is nested within the garment structure, specifically routed through cord retaining guide means that are integrated into the garment's fabric. The cord is concealed inside the garment's sleeves and body, similar to a nested doll structure, allowing the weapon to be carried without external visibility. This nesting approach enables the cord to be portable and inconspicuous while remaining accessible for self-defense.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Speed

If a weapon is carried externally or in a pocket, then accessibility for self-defense is improved, but mobility and comfort deteriorate due to fumbling and inconvenience

Engineering Contradiction:

Improveaccessibility for self-defenseVSAvoidmobility and comfort

Core Design Contradiction:

SpeedVSEase of operation

Solution Approach 1:

The cord is pre-positioned and concealed within the garment structure, with ends accessible at the sleeve cuffs. The cord retaining guide means is permanently integrated into the garment, so no fumbling or searching is required during deployment. The wearer can immediately access the cord by reaching into the sleeve, as the weapon system is already in place and ready for use. This preliminary positioning resolves the contradiction between quick accessibility and mobility comfort.

Inventive Principle:

Principle #10Preliminary action

3Difficulty of detecting and measuring

If the cord is concealed within the garment, then surprise advantage is improved, but accessibility and deployment speed deteriorate

Engineering Contradiction:

Improvesurprise advantageVSAvoiddeployment speed

Core Design Contradiction:

Difficulty of detecting and measuringVSSpeed

Solution Approach 1:

The cord is segmented into multiple sections, with portions concealed within different parts of the garment (sleeves, body). The cord retaining guide means is divided into multiple sections distributed throughout the garment structure. This segmentation allows the cord to remain concealed for surprise advantage while enabling rapid deployment through localized access points at the sleeve cuffs, resolving the contradiction between concealment and deployment speed.

Inventive Principle:

Principle #1Segmentation

4Difficulty of detecting and measuring

If the cord retaining guide means is integrated into the garment, then concealment is improved, but device complexity deteriorates

Engineering Contradiction:

ImproveconcealmentVSAvoiddevice complexity

Core Design Contradiction:

Difficulty of detecting and measuringVSDevice complexity

Solution Approach 1:

The cord retaining guide means serves multiple functions: it conceals the cord within the garment, guides the cord along a predetermined path, retains the cord in a ready position, and facilitates rapid deployment. This multi-functionality reduces the need for separate components, simplifying the overall device while maintaining effective concealment. The guide means is integrated into the garment fabric itself, further reducing complexity while achieving the desired concealment效果.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A self-defense garment assembly is further provided, including a garment for covering at least the body of a wearer having a garment interior surface; a cord retaining guide structure extending substantially within the garment along the garment interior surface; and a pull cord having a cord first end and a cord second end which is slidably retained within the cord retaining guide structure; so that at least a segment of the cord can be pulled out of the garment and used to fight a combat opponent.
