Solution Overview

Problem

Existing phone cases for concealed defense systems, such as pepper spray and handguns, are cumbersome and lack efficient concealment and quick deployment mechanisms, posing safety and usability issues.

Innovation Solution

A phone case with a removably attached concealed defense system, featuring a mini pepper spray canister or defense projectile device, utilizing attachable means like velcro or dual lock, allowing for easy attachment and detachment, and incorporating safety features to prevent accidental discharge, with the option to hide the system under a flap or cover.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If pepper spray or handgun is carried for self-defense, then personal safety is improved, but portability and concealment are worsened

Engineering Contradiction:

Improvepersonal safetyVSAvoidportability

Core Design Contradiction:

ReliabilityVSWeight of moving object

Solution Approach 1:

The patent combines the defense system (pepper spray canister or handgun) with a phone case, creating a unified portable unit. The defense system is housed within the phone case structure, allowing the user to carry both phone and defense tool together without the additional weight and bulk of separate carrying cases or holsters.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The defense system components are nested within the phone case structure. The pepper spray canister fits inside a compartment of the phone case, or the handgun is stored within the case's internal cavity, enabling compact concealment while maintaining quick access capability.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Weight of moving object

If defense system is concealed in phone case, then safety and portability are improved, but quick deployment is worsened

Engineering Contradiction:

ImproveportabilityVSAvoiddeployment time

Core Design Contradiction:

Weight of moving objectVSLoss of time

Solution Approach 1:

The phone case is pre-configured with dedicated compartments, attachment mechanisms (velcro, dual lock), and quick-release features that enable immediate deployment. The defense system is positioned and secured in advance within the case structure, so when needed, the user can quickly access and deploy it without complex manipulation or assembly steps.

Inventive Principle:

Principle #10Preliminary action

3Loss of time

If defense system is made accessible, then quick deployment is improved, but safety and concealment are worsened

Engineering Contradiction:

Improvedeployment timeVSAvoidaccidental discharge

Core Design Contradiction:

Loss of timeVSObject-affected harmful factors

Solution Approach 1:

Different regions of the phone case have different functional properties: the main body provides secure concealed storage with restricted access, while specific access points feature quick-release mechanisms for rapid deployment. The trigger guard and safety features are localized to protect against accidental discharge while maintaining operational accessibility when intentionally activated.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The phone case structure acts as an intermediary between the defense system and the user. It provides a controlled interface with safety features (triggers, guards, covers) that mediate access to the defense system, preventing accidental discharge while enabling intentional quick deployment through designated mechanisms.

Inventive Principle:

Principle #24Intermediary (Mediator)
