Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solutions for transporting items to the beach, such as bags, backpacks, and standard wagons, fail to meet market needs due to weight issues, inability to carry multiple items, and difficulty navigating sandy terrain.
Innovation Solution
A self-powered, collapsible wagon with a foldable frame assembly, wide wheels, and a motorized system for easy movement, equipped with Bluetooth capabilities, GPS, and a handle for remote control, designed to handle sand, grass, and snow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a standard wagon is used, then items can be carried, but it gets bogged down in sand and is too bulky to carry around in the car
Solution Approach 1:
The wagon is divided into modular components including a collapsible frame assembly, separate wheel units, and a removable container assembly. Each segment can be independently folded or detached, allowing the wagon to be disassembled into compact components for car transport while maintaining full functionality on sand when assembled
Solution Approach 2:
The wagon incorporates dynamic elements including collapsible frame members that transition between extended and folded states, adjustable wheel units that can be positioned or removed, and a container assembly that can be detached. These dynamic features allow the wagon to adapt between being a fully functional beach wagon and compact transportable components
2Quantity of substance
If a bag or backpack is used, then items can be carried, but they become heavy and cannot carry many items
Solution Approach 1:
The patent replaces the manual carrying mechanism of bags and backpacks with a motorized drive system. The motor assembly propels the wagon through sand using driven wheels, eliminating the need for the carrier to physically lift or drag the load. This mechanical substitution allows the wagon to carry heavy items without increasing the carrier's weight, as the motor provides the propulsive force
3Adaptability or versatility
If a standard wagon is used, then items can be transported, but it is not collapsible to carry around in the car
Solution Approach 1:
The wagon is divided into modular components including a collapsible frame assembly, separate wheel units, and a removable container assembly. Each segment can be independently folded or detached, allowing the wagon to be disassembled into compact components for car transport while maintaining full functionality on sand when assembled
Solution Approach 2:
The wagon components are designed to nest within each other when collapsed. The frame members fold inward, wheel units can be positioned within the frame structure, and the container assembly can be stored within or attached to the collapsed frame. This nesting capability minimizes the space required for car transport while maintaining the complete wagon structure when deployed at the beach
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The powered wagon provides a portable, lightweight, and efficient means to carry items on sandy surfaces, avoiding the limitations of previous solutions by dispersing weight and offering navigation and communication features.
Implementation Method 1
A motor and shaft assembly is contained within the housing assembly and is electrically coupled to a rechargeable battery assembly (power source) and an actuator assembly, the motor and shaft assembly rotationally coupled to the front two-wheel frame assembly
Implementation Method 2
electrically coupled to a rechargeable battery assembly (power source)
Implementation Method 3
Four wheel and axle assemblies that rest on a surface such as sand

AI summary
A powered wagon for carrying items on sand for a user that has a foldable frame assembly and foldable, fabric container assembly with an open top portion. The wagon includes a front two-wheel frame assembly and back two-wheel frame assembly, with the back two-wheel frame assembly being inwardly and outwardly slidable along a back support bar and designed to nest between the front two-wheel frame assembly when the foldable frame assembly is retracted. A handle and telescoping bar assembly is pivotally coupled substantially to a housing assembly on the bottom frame portion, a handle portion defining the proximal bar end. A motor and shaft assembly in the housing assembly is electrically coupled to a rechargeable battery assembly, an actuator assembly, and electronic controls which are communicatively coupled to a hand-held communication or smart device.
