Design of a Solar Energy Storage Emergency Rescue Backpack Integrated With Global Positioning System, Light Emitting Diode, and a Heating Module

ABSTRACT Mountain climbing often involves sudden weather changes, group separation, and mobile device battery depletion, which can lead to life‐threatening emergencies. Enhancing survival and extending rescue time in such situations are crucial, making power supply and emergency equipment essential considerations. Existing equipment designs have emphasized solar power, lighting, communication, or navigation, but few address an integrated solution that simultaneously addresses survival needs such as warmth, power supply, and location tracking. To overcome these limitations, this study presents the design of an emergency rescue backpack, which serves as a self‐rescue and assisted‐rescue tool for climbers stranded in mountainous terrain. The backpack is equipped with light emitting diode (LED) light strips, a heating module, a global positioning system (GPS) tracking system, and a flexible solar photovoltaic panel integrated with a portable power bank. A key innovation of this study lies in the integration of the heating module, which utilizes a carbon fiber heating element sewn into the back of the backpack. By hugging the backpack, climbers can generate and retain heat to help maintain body temperature in cold environments, thereby reducing the risk of hypothermia. Additionally, the LED lighting provides illumination for nighttime navigation and deters wildlife. The GPS enables rescuers to track the stranded individual's location via satellite positioning. The flexible solar panel converts sunlight into electrical energy, which is stored in the internal power bank. Moreover, a switch‐controlled USB hub with four ports is installed to minimize power consumption when not in use. Therefore, the practical contribution of the overall design is to extend rescue time and enhance the survival chances of lost hikers.
