Wireless Personal Safety Device via Bluetooth Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing personal safety devices that combine cellular phones with personal protective features are often bulky, require modification of the phone, and do not work in conjunction with other personal safety devices over a personal area network, limiting their effectiveness and usability.
Innovation Solution
A wireless personal safety device that includes a shocking mechanism and a sprayer, integrated with a cellular phone via Bluetooth, allowing for self-defense capabilities and communication with emergency services, while also providing assailant detection and location tracking through a separate optical safety device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If personal safety devices are physically attached to cellular phones, then self-defense capability is provided, but the device becomes bulkier and heavier
Solution Approach 1:
The patent divides the personal safety system into separate components: a wireless personal safety device and a cellular phone that communicate via Bluetooth. This segmentation allows each device to maintain its own optimal weight and form factor while providing combined functionality through wireless communication.
Solution Approach 2:
The patent introduces Bluetooth wireless communication as an intermediary between the personal safety device and the cellular phone. This mediator enables data transmission and coordination between the two devices without requiring physical attachment, thus avoiding the weight and bulk issues of direct integration.
2Adaptability or versatility
If cellular phones are modified to include personal safety features, then integrated functionality is achieved, but the phone becomes less useful and bulkier
Solution Approach 1:
The patent separates the personal safety functionality into a dedicated wireless device that communicates with the phone via Bluetooth. This keeps the phone's interface and operation unchanged while providing integrated functionality through the paired safety device, avoiding clutter and complexity on the phone itself.
3Adaptability or versatility
If standard cellular phone attachments are used for personal safety devices, then compatibility is achieved, but different phone implementations make common attachment difficult
Solution Approach 1:
The patent replaces mechanical attachment systems with Bluetooth wireless communication. This eliminates the need for physical adapters, clips, or mounts that would need to accommodate different phone shapes and sizes. The wireless connection provides universal compatibility across all Bluetooth-enabled devices without requiring mechanical adaptation.
Data Source
AI summary
A personal protective device is combined with a cellular telephone. Activation of either device causes activation of the other device. Activation is achieved by a switch or voice command. Upon activation, a message asking for assistance at the present location is sent to a previously agreed upon emergency contact. The smartphone also starts both audio and video recording, which are also part of the data sent to the emergency contact person or service. Additionally, the personal protective devices are integrated into a unit that may combine such items as a protective spray, Taser, strobe light, dye pack, siren and other deterrent technologies to ward off would-be attackers. These devices are integrated into a hand held unit that can be unobtrusively worn or carried in a purse or pocket. An optical safety device is included to protect the user from a potential assailant approaching from rearward.
