Polypropylene Exercise Board with Curved Bottom for Rotational Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional exercise boards for simulating surfing, snowboarding, and skateboarding are limited in their ability to replicate the full range of movements required for these sports, are not suitable for use in inclement weather, and are heavy, expensive, and prone to damage, making them unsuitable for year-round use and transportation.
Innovation Solution
A lightweight, durable, all-weather exercise apparatus with a concave shape and adjustable angles that allows for rotational and lateral movement, manufactured from polypropylene or polyethylene for enhanced resilience and portability, enabling side-to-side and rotational movements similar to surfing, snowboarding, and skateboarding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional exercise boards use wood or laminate board materials, then they provide structural strength, but they become heavy and difficult to transport
Solution Approach 1:
The patent uses a composite construction combining a lightweight core material (such as foam or honeycomb structure) with thin layers of durable material on the top and bottom surfaces. This composite approach provides the necessary structural strength while keeping the overall weight low for portability.
Solution Approach 2:
The patent employs thin, flexible shell structures for the board body instead of thick solid wood or laminate construction. These thin films and shells provide sufficient strength while dramatically reducing weight, enabling easy transport by users.
2Strength
If conventional exercise boards use wood or laminate board materials, then they provide structural strength, but they become expensive to produce
Solution Approach 1:
The composite material construction allows for more cost-effective production by using inexpensive core materials (such as molded foam or cardboard honeycomb structures) combined with thin, cheap protective layers, replacing expensive wood and laminate materials while maintaining structural integrity.
Solution Approach 2:
The patent adopts a design philosophy of using inexpensive, easily replaceable materials that can be manufactured at low cost. The board is designed to be affordable enough that replacement is economically viable, using materials like high-density foam and thin plastic or fabric coverings instead of expensive hardwoods.
3Strength
If conventional exercise boards use wood or laminate board materials, then they provide structural strength, but they warp, breakdown or crack after continued use and exposure to sun, rain and other elements
Solution Approach 1:
The patent uses flexible, weather-resistant shell materials such as marine-grade vinyl, polyester fabric, or UV-stabilized plastic laminates that cover the core structure. These thin film layers are highly resistant to moisture, UV radiation, and temperature variations, preventing warping, cracking, and breakdown even in harsh outdoor conditions.
Solution Approach 2:
The patent changes the material parameters by selecting materials with high resistance to environmental degradation - using closed-cell foam materials that resist water absorption, UV-stabilized polymers that resist sun damage, and corrosion-resistant fasteners. These parameter changes in material selection ensure long-term reliability in varying weather conditions.
4Ease of operation
If conventional exercise boards include a dowel or roller device, then they enable front to back movement, but they can generally only be used on hard or smooth surfaces
Solution Approach 1:
The patent replaces the rigid dowel or roller device with a flexible bottom surface made of soft, compliant material such as rubber, foam, or fabric. This flexible shell allows the board to adapt to various surface textures including grass, sand, snow, and uneven ground, providing stable movement across diverse terrains without requiring hard or smooth surfaces.
5Stability of the object's composition
If conventional exercise boards are manufactured from wood or laminate board, then they provide structural stability, but they are relatively heavy and difficult to transport
Solution Approach 1:
The patent employs composite material construction with a lightweight core (such as molded foam, balsa wood, or honeycomb structure) sandwiched between thin, strong layers. This composite approach maintains structural stability and rigidity while keeping the overall weight low, enabling easy transport and portability.
Solution Approach 2:
The patent incorporates curved, rounded edges and a slightly arched bottom surface design that distributes structural stress more effectively throughout the board. This curvature provides structural stability without requiring heavy materials, while also improving aerodynamics and reducing weight compared to flat, rigid constructions.
