Phone Case Integrating Self-Defense Spray and Wireless Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional self-defense systems often fail to provide immediate and convenient access to self-defense sprays, as users may not carry them at all times and can forget to do so, leaving them vulnerable in dangerous situations.
Innovation Solution
A phone case with a built-in cavity for a self-defense spray and a 2-step activation button, which also communicates with the phone's wireless technology to send alerts and notifications, ensuring the spray is always accessible and can trigger emergency alerts when activated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users carry separate self-defense spray and phone, then they can access self-defense spray, but they may forget to carry it or not have immediate access when needed
Solution Approach 1:
The patent combines the self-defense spray container with the phone case into a single integrated unit. The spray container is positioned within the phone case structure, allowing users to carry both items together without forgetting either. This merging ensures continuous availability and immediate accessibility of the self-defense spray whenever the user carries their phone.
Solution Approach 2:
The phone case serves multiple functions: it protects the phone, provides a carrying container for the self-defense spray, and offers immediate access mechanisms. By making the phone case multi-functional, the patent eliminates the need for separate carrying items and ensures the spray is always available when the user needs it most.
2Object-affected harmful factors
If users carry self-defense spray separately, then they can use it for protection, but they increase the risk of forgetting it or having delayed access
Solution Approach 1:
The self-defense spray is pre-positioned within the phone case during manufacturing, so it is already ready for immediate use. The user does not need to separately carry or remember to bring the spray, as it is preliminarily integrated into the phone case that they already carry daily. This eliminates time loss and ensures instant availability when an attack occurs.
3Ease of operation
If the phone case includes built-in spray storage, then immediate access is ensured, but the device complexity increases
Solution Approach 1:
The phone case is segmented into distinct functional zones: a protective case structure for the phone and an integrated container section for the spray. This segmentation allows the spray storage to be incorporated without compromising the phone case's primary function, and enables independent access to the spray through a dedicated mechanism while keeping the overall design modular and manageable.

AI summary
A phone case with a liquid vessel contained therein for emitting a spray, such as a spray for self-defense or any other practical use, includes a case body extending from a first end to a second end, the case body to secure to a phone; a cavity disposed between an interior surface and an exterior surface of the case body; a button extending through a first opening of the case body and into the cavity; a nozzle extending through a second opening of the case body and into the cavity; and a vessel mounted within the cavity and engaged with the button and in fluid communication with the nozzle; activation of the button activates spray from the vessel through the nozzle.
