Innovation Solution
A transformable multifunction backpack with retractable rods, a detachable base rolling board, and various configurations such as a stroller, shopping cart, scooter, and stretcher, allowing for multiple uses and user assistance through adjustable and detachable components like retractable rods and a child strap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional backpack design with fixed shoulder straps is used, then the backpack structure is simple, but the functionality is limited and cannot adapt to different carrying needs
Solution Approach 1:
The backpack integrates multiple functions including carrying mode, rolling mode, and child-carrying mode within a single device. The shoulder straps can be detached and reconfigured, the base rolling board can be attached or removed, and the child strap can be installed, allowing the backpack to serve as a traditional backpack, a rolling luggage, or a child carrier depending on configuration
Solution Approach 2:
The backpack is divided into separable components: the main backpack body, detachable shoulder straps, detachable base rolling board with wheels, and child strap. These modular components can be independently attached or removed to transform the backpack's functionality and adapt to different usage scenarios
2Ease of operation
If rolling luggage design with wheels and handle is used, then the cargo carrying volume is increased and easier to move, but the device is heavier and更适合 for flat surfaces
Solution Approach 1:
The backpack features a dynamic configuration system where the base rolling board with wheels can be attached when rolling capability is needed for easy movement on flat surfaces, and detached when traditional backpack carrying is preferred. The shoulder straps can be adjusted or removed based on usage requirements, allowing the device to adapt its characteristics to different operational conditions
3Adaptability or versatility
If detachable components and transformable structures are added to enhance versatility, then the functionality is expanded, but the device complexity increases
Solution Approach 1:
The backpack is divided into separable components: the main backpack body, detachable shoulder straps, detachable base rolling board with wheels, and child strap. These modular components can be independently attached or removed to transform the backpack's functionality and adapt to different usage scenarios
Solution Approach 2:
The backpack includes pre-provided attaching means such as slots, brackets, packets, zippers, and Velcro® straps that are built into the design from the beginning. These pre-configured attachment mechanisms make it easy to assemble and disassemble different components without requiring complex tools or procedures, thus managing complexity through thoughtful preliminary design

AI summary
The present invention discloses a transformable multifunction backpack, including a main backpack body, retractable rods, and detachable rods. The retractable rod has a fixed portion and a handle portion; the fixed portion is stored within the main backpack body, and the handle portion can extend out of the fixed portion telescopically. The retractable rod and the detachable rod are attached together with a lockable means, such as a lockable pin, for quick release and adjustment. The backpack also includes a rolling base board which can be placed under the backpack body, or been used as a skateboard. The retractable rod can also be used as a cane. The main backpack body also has a child strap for carrying a small child. The backpack main body is comprised of several different fabric pieces, connected together with a connecting means, such as zippers or buttons.
