Beach Trolley Inflatable Wheels Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional baby strollers are not adapted for use on sandy surfaces like beaches and struggle to move efficiently or be compactly stored, limiting their functionality and portability.
Innovation Solution
A beach trolley design featuring lateral and central arms with removable inflatable wheels, a flexible seat, and a pulling arm that allows for pivotal movement between a trolling configuration for easy movement on sand and a compact configuration for storage, enabling efficient transport and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional baby strollers are used on sandy surfaces, then they can transport children, but they cannot move efficiently on sand
Solution Approach 1:
The patent changes the physical parameters of the wheels by making them inflatable with low pressure, allowing the tires to deform and conform to sandy surfaces. This parameter change enables the stroller to move efficiently on sand while maintaining its child transport function
Solution Approach 2:
The patent introduces collapsible and expandable structural elements that allow the stroller to dynamically change its configuration. The frame can be collapsed for easy transport and expanded for use, providing adaptability to different terrain conditions including sandy surfaces
2Productivity
If oversized beach wheels are added to conventional strollers, then movement on sand improves, but the stroller becomes cumbersome to carry and move in crowded places
Solution Approach 1:
The patent employs dynamically adjustable wheel sizes that can be inflated to large dimensions for beach use and deflated for compact storage and transport. This dynamic adjustment resolves the contradiction between needing large wheels for sand mobility and requiring compact dimensions for portability
Solution Approach 2:
The patent segments the wheel system into removable, inflatable components that can be independently adjusted. This segmentation allows the wheels to be optimized for different functions (large for sand, small for storage) without compromising the overall stroller structure
3Volume of moving object
If conventional strollers are designed for limited child carrying space, then they are compact for storage, but they lack space to carry additional items or bags
Solution Approach 1:
The patent incorporates dynamically expandable storage compartments that can be extended when needed and collapsed when not in use. This dynamic design provides additional space for items and bags during beach trips while maintaining a compact form factor for storage
Solution Approach 2:
The patent designs the stroller with multi-functional components that serve both child transport and cargo carrying functions. The expanded frame structure provides both a safe space for the child and additional storage areas for beach equipment and personal items

AI summary
A beach trolley includes two lateral arms, a central arm therebetween and a pulling arm that is aligned with the central arm. Each of the two lateral arms and central arm having a removable inflatable wheel at one end and being joined at the other end for pivotal movement between a trolling configuration wherein the two lateral arms and the central arm generally lie within a same plane and a compact configuration wherein the two lateral arms and the central arm are generally parallel. The pulling arm is joined to the two lateral arms and the central arm for pivotal movements towards and away the two lateral arms and the central arm. The beach trolley further includes a flexible seat attached to the arms to form a) a seat therebetween when the two lateral arms and the central arm are in the trolling configuration and b) a bag therewith when i) the two lateral arms and the central arm are in the compact configuration and ii) the pulling arm is pivoted so as to be generally parallel to the two lateral arms and the central arm.
