Transformable Utility Mat Structure for Wind-Stable Beach Shelter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional beach mats are inadequate as they are not versatile enough to convert into multiple forms like a backpack bag, surfboard carrier sling, and shade shelter, lack a secure closure mechanism, and do not provide adequate protection from rain or stability in windy conditions.
Innovation Solution
A multi-purpose mat with a circular shape, featuring a waterproof EVA film cushion, structural fold pattern, wing pockets, webbing straps, and tent poles that can transform into a beach mat, backpack bag, surfboard carrier sling, and shade shelter, providing additional storage, protection from elements, and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If traditional beach mats are made lightweight for portability, then ease of transport is improved, but stability in windy conditions deteriorates
Solution Approach 1:
The beach mat is divided into multiple panels that can be folded together, creating a compact yet stable structure. The segmented design allows the mat to maintain rigidity when deployed while remaining lightweight and portable when folded.
Solution Approach 2:
The beach mat panels are designed to nest within each other when folded, similar to nested dolls. This nesting mechanism allows the mat to be compact for transport but expands to a stable, large surface area when deployed on the beach.
2Ease of manufacture
If traditional beach mats are made rectangular for simplicity, then manufacturing ease is improved, but adaptability to multiple functions deteriorates
Solution Approach 1:
The beach mat is designed with multiple panels and attachment mechanisms that enable it to serve multiple functions: as a traditional beach mat, as a backpack for carrying beach gear, and as a shelter when combined with poles. The modular panel design facilitates these different configurations.
Solution Approach 2:
The mat incorporates dynamic elements such as foldable panels and adjustable straps that allow it to change configuration based on usage needs. The structure transitions from a flat mat to a three-dimensional backpack or shelter configuration through mechanical manipulation.
3Device complexity
If traditional mats lack closure mechanisms for simplicity, then device complexity is reduced, but security of stored items deteriorates
Solution Approach 1:
The mat incorporates self-service closure mechanisms such as drawstrings and Velcro straps that allow users to quickly secure the mat into a backpack configuration without requiring complex fastening systems. The design enables automatic tightening and securing through simple user actions.
4Weight of moving object
If traditional mats are made narrow for portability, then ease of transport is improved, but comfort for accommodating people and accessories deteriorates
Solution Approach 1:
The mat uses a nested folding design where multiple large panels are folded within each other, creating a compact package for transport. When deployed, the full surface area of all panels is available, providing ample space for comfort and accessories.
Solution Approach 2:
The mat transitions from a two-dimensional folded state to a three-dimensional deployed state, utilizing vertical space and panel layering to maximize surface area when in use while maintaining compactness for transport.

AI summary
A multi-purpose mat comprises a circular flat body portion having an inner surface and an outer surface. The inner surface comprises a structural fold pattern. The outer surface comprises a plurality of wing pockets extending from a peripheral edge and spaced at ninety degree intervals that may be folded into a plurality of interior pockets between the outer surface and the inner surface, a drawstring interwoven through a plurality of eyelets along the perimeter, a pair of webbing straps positioned at right angles to each other, and a pair of pole pockets below the pair of webbing straps, a bag clip and a bag handle. A functional strap and a plurality of tent poles allow the multi-purpose mat to be configured into a beach mat, a backpack bag, a surfboard carrier sling and a shade shelter.
