Insulated Solar Backpack for Separate Hot-Cold Storage and Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional backpacks fail to maintain both hot and cold temperatures simultaneously in their compartments and lack the ability to harness solar power for charging electronic devices, making them inconvenient for outdoor use and requiring additional devices.
Innovation Solution
A thermally insulated backpack with independent upper and lower compartments for maintaining desired temperatures and an integrated solar panel that converts solar energy into reusable power for charging via USB ports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional backpacks are used for transporting food, then the backpack is simple and easy to carry, but the backpack cannot maintain the temperature of food and beverages
Solution Approach 1:
The backpack is divided into multiple independent compartments (first compartment for hot food, second compartment for cold food, third compartment for beverages) that can be separated or removed. Each compartment has insulating walls to maintain temperature, allowing the backpack to function as a simple carrier when compartments are removed or as a temperature-controlled container when compartments are installed.
2Temperature
If temperature-controlled storage compartments are added to maintain both hot and cold items, then temperature maintenance is improved, but the backpack requires multiple separate devices or compartments
Solution Approach 1:
The patent combines multiple temperature-controlled storage functions into a single integrated backpack structure. The first compartment with heating element, second compartment with cooling element, and third beverage compartment are all merged into one backpack body, allowing simultaneous maintenance of hot and cold temperatures without requiring multiple separate devices.
Solution Approach 2:
The backpack is designed to perform multiple functions: it can store hot food, cold food, and beverages simultaneously; each compartment can be used independently or in combination; the backpack can function as a simple carrier or as a fully temperature-controlled container depending on whether compartments are installed.
3Adaptability or versatility
If electronic devices are carried for outdoor navigation and communication, then safety and navigation capability are improved, but the electronic devices require additional charging devices when power outlets are unavailable
Solution Approach 1:
The solar panel charging system is integrated directly into the backpack structure. The solar panel is mounted on the exterior of the backpack, and the battery and charging circuitry are built into the backpack body, allowing electronic devices to be charged without requiring separate portable charging equipment.
Solution Approach 2:
The backpack generates its own power through the integrated solar panel, which converts sunlight into electrical energy stored in an internal battery. This self-powered system eliminates the need for external power sources or additional charging devices, allowing the backpack to charge electronic devices autonomously when exposed to sunlight.

AI summary
A thermally insulated solar rechargeable backpack is provided. The device includes a plurality of compartments that are thermally insulated. The plurality of compartments may keep items placed therein either hot or cold. The backpack includes a plurality of zippers to maintain the temperature in the compartments and keep the contents from falling out of the backpack. Additionally, the sides of the backpack have at least one storage pocket. Moreover, a solar panel is disposed on the top of the backpack to power a plurality of USB charging ports for charging electronic devices. In this way, the insulated backpack may be utilized to thermally insulate items to keep them either hot or cold in separate compartments during their transportation and utilize solar energy to provide power through a plurality of charging ports.
