Sloped Ball Return Device for Goal Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current in-goal ball return devices are inefficient, as they often require significant time and effort to retrieve balls, especially when target devices block the goal entrance, and existing solutions can hinder gameplay or get caught in the goal netting, leading to interruptions and ball loss.
Innovation Solution
A portable, adjustable ball return device with a sloped surface made of durable, flexible material that integrates with the goal netting, allowing balls to roll back out easily, and an optional retention flap to prevent balls from exiting the goal during gameplay, designed for various sports and goal types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a target device is placed in the goal entrance to block shots, then shooting accuracy is improved, but ball retrieval becomes difficult and time-consuming
Solution Approach 1:
The ball return device is divided into multiple fabric panels joined by gusset seams, creating a segmented structure that can navigate around target devices and goal frames while maintaining functionality. This segmentation allows the device to access balls without requiring complete goal disassembly.
Solution Approach 2:
The ball return device acts as an intermediary mechanism between the goal and the retrieving person. It collects balls from various positions within the goal and delivers them to a centralized exit point, mediating the complex retrieval process and reducing direct interaction time with blocked areas.
2Strength
If a rigid ball return structure is used to ensure durability, then structural strength is improved, but the device gets caught in goal netting and becomes difficult to remove
Solution Approach 1:
The ball return device uses flexible fabric panels instead of rigid structures. These fabric panels can bend and flex to navigate through goal netting without becoming entangled, while gusset seams provide structural reinforcement at critical joints to maintain durability. The flexible nature allows easy removal and repositioning.
Solution Approach 2:
The device combines flexible fabric materials with reinforced gusset seams creating a composite structure. The fabric provides flexibility and netting penetration capability, while the gusset seams add structural strength at stress points, achieving both durability and ease of operation.
3Productivity
If the ball return device is integrated permanently into the goal, then ball collection efficiency is improved, but adaptability to different goal configurations is reduced
Solution Approach 1:
The ball return device is designed as a dynamic, reconfigurable system rather than a fixed structure. The fabric panels can be attached and detached from various goal configurations, and the device can be repositioned within the goal as needed. This dynamic design maintains high ball collection efficiency while adapting to different goal types and setups.
Solution Approach 2:
The device is designed with universal attachment capabilities that work with multiple goal configurations and sports equipment. The same basic device structure can be adapted to different goal sizes, shapes, and netting types, providing multi-functional versatility without sacrificing ball collection efficiency.
4Area of stationary object
If a large ball return device is used to cover the entire goal area, then ball retrieval coverage is improved, but it obstructs gameplay and goal access
Solution Approach 1:
The ball return device is segmented into multiple smaller fabric panels that can be strategically positioned to cover different areas of the goal. This segmentation provides comprehensive ball retrieval coverage while leaving gaps and pathways that maintain goal accessibility for players and coaches.
Solution Approach 2:
The device utilizes the three-dimensional space within the goal by extending fabric panels at various angles and depths. This dimensional approach allows coverage of balls scattered throughout the goal volume without creating a flat barrier that would block goal access, maintaining gameplay flow while improving retrieval coverage.
