Solution Overview

Problem

Current sand training solutions lack the ability to create an expansive, customizable sand pit for varied exercises and rehabilitation, as they are limited in size and flexibility, and do not effectively simulate diverse surfaces for training purposes.

Innovation Solution

A modular sand pit training bag system with attachable walls and releasable fasteners, allowing users to create a large, open sand pit configuration with an unlimited perimeter, using hook-and-loop devices, zippers, or other fastening mechanisms, and an optional compressed surface cover for added cushioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If sand training is performed on a fixed-size surface, then the training area is limited, but the portability and ease of setup are maintained

Engineering Contradiction:
Improvesand pit areaVSAvoidbag structure complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The sand pit training bag is divided into multiple modular panels that can be connected together. Each panel is a separate component with attachment mechanisms, allowing users to assemble different configurations (single bag, dual bag, quadruple bag) to create varying sand pit areas while maintaining portability and ease of setup.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the sand pit configuration is fixed, then setup is simple, but versatility for different exercises and surfaces is reduced

Engineering Contradiction:
Improvetraining surface varietyVSAvoidsetup complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The bag structure incorporates dynamic reconfigurability through releasable fasteners and attachable panels. Users can easily modify the sand pit configuration during setup or storage by attaching or detaching panels, allowing the same system to adapt to different exercise requirements and surface simulations without permanent modifications.

Inventive Principle:
Principle #15Dynamics

3Area of stationary object

If additional walls are added to expand the sand pit perimeter, then the training area increases, but the number of components and assembly complexity increases

Engineering Contradiction:
Improvesand pit perimeterVSAvoidnumber of components
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

Each bag panel is designed as a universal module that can function in multiple positions and configurations. The same panel can be used as a side wall, end wall, or connector piece depending on how it's attached to other panels. This universality allows the system to expand the sand pit perimeter using standardized components rather than requiring unique pieces for each position.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A sand training bag for sand and/or mineral training in an open and closed configuration. The sand pit training bags includes a sand pit training bag configuration comprising at least one fastener and at least one overlaying fabric around the perimeter to open flat on a surface. The sand training bag includes attachable wall structure, wherein the surface attachable wall structure is configured with a sand pit training bag in an open configuration visible relative to a sand or mineral pit held by one or more fasteners. The sand training bag includes a single sand pit training bag, wherein the single sand pit training bag is convertible to a single sand pit with at least one attachable perimeter wall around the perimeter of the open sand or mineral receiving surface configuration, wherein a top cover is configured to be viewed as a sand or mineral pit closed configuration.
