Adjustable 3D Goal Structure for Portable Ball Games
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ball games require two-dimensional goals, limiting the creativity and variety of gameplay, and often necessitate large playing areas.
Innovation Solution
A three-dimensional goal with adjustable size, formed as a polyhedron, such as a cube, allowing players to throw an object into openings from outside the court perimeter, which can be easily assembled and disassembled for portability and affordability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a three-dimensional polyhedral goal is used instead of a two-dimensional goal, then the gameplay variety and creativity are improved, but the device complexity increases
Solution Approach 1:
The three-dimensional goal is divided into multiple planar panels or surfaces that are connected at edges to form a polyhedral structure. Each panel can be independently manufactured and then assembled together, reducing the overall manufacturing complexity while maintaining the 3D shape. This segmentation allows the complex 3D form to be built from simpler 2D components.
Solution Approach 2:
The goal structure incorporates nested or layered panels where inner panels are positioned within outer panels, creating the three-dimensional polyhedral form. This nesting approach allows the complex 3D structure to be compactly organized and efficiently manufactured while maintaining structural integrity and gameplay functionality.
2Adaptability or versatility
If the goal is made adjustable in size, then the adaptability to different playing settings is improved, but the device complexity increases
Solution Approach 1:
The goal incorporates movable joints and adjustable connections between its panels, allowing the structure to dynamically change its size and configuration. These dynamic elements enable players to adjust the goal dimensions to suit different playing conditions while maintaining structural stability through mechanical linkage designs.
Solution Approach 2:
The adjustment mechanism is designed with universal components that can accommodate multiple size configurations and playing scenarios. The same mechanical elements serve both structural support and size adjustment functions, reducing the need for separate adjustment devices and minimizing overall complexity.
3Ease of operation
If the goal is made light-weight for easy transport, then the ease of operation is improved, but the structural strength may worsen
Solution Approach 1:
The goal panels are constructed from thin-walled tubular structures or hollow chambers that provide high strength-to-weight ratio. These thin-walled forms maintain structural integrity through their geometric shape and material distribution, enabling the goal to be lightweight for portability while retaining sufficient strength to withstand gameplay forces.
Solution Approach 2:
The goal structure utilizes composite materials combining lightweight components with reinforcing elements. The composite construction provides both the low weight needed for easy transport and the structural strength required for durable gameplay, achieving a balance between portability and durability through material optimization.
