Innovation Solution
A portable battery charger incorporating a rechargeable battery, a security assembly with a pepper spray dispenser, high definition camera, voice recorder, and GPS tracking, along with a communication assembly for wireless connectivity and real-time streaming, to provide comprehensive safety and emergency response features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate devices (battery charger, pepper spray, camera) are carried by a user, then each device can perform its specific function effectively, but the number of devices increases and portability is reduced
Solution Approach 1:
The patent combines a battery charger, pepper spray dispenser, and camera into a single integrated device. The housing contains both the rechargeable battery/charging circuitry and the security features (pepper spray, camera, voice recorder), allowing users to carry one device instead of multiple separate devices while maintaining all individual functions.
Solution Approach 2:
The device is designed to perform multiple functions: charging portable electronic devices, providing pepper spray protection, recording video and audio, and GPS tracking. This multi-functional design eliminates the need for users to carry separate devices for each function, directly resolving the contradiction between versatility and device count.
2Reliability
If security features such as pepper spray and camera are added to a portable charger, then user safety is enhanced, but the device complexity and manufacturing cost increase
Solution Approach 1:
The security features (pepper spray dispenser, camera, voice recorder) are integrated into the same housing as the battery charger, sharing common structural elements and power supply. This merging approach enhances security functionality while minimizing the increase in overall device complexity compared to separate devices.
Solution Approach 2:
The device uses a universal power source (rechargeable battery) that supplies energy to all functions including charging external devices, operating the pepper spray dispenser, running the camera and voice recorder, and powering GPS tracking. This multi-functional architecture achieves enhanced reliability without proportionally increasing complexity.
3Device complexity
If a portable charger is combined with security devices, then the number of devices to carry is reduced, but the weight and volume of the single device increase
Solution Approach 1:
By merging the battery charger and security devices into a single unit, the patent eliminates the weight of multiple separate devices' housings, buttons, and connectors. Although the integrated device contains more components, the shared structural elements and optimized layout reduce the overall weight compared to carrying multiple separate devices.
