Weighted Roller Soccer Goal Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Soccer goal structures are inherently unstable and prone to shifting or tipping, posing safety hazards due to high winds, player impact, or improper use, and existing solutions like stakes or weights are not effective in maintaining stability while allowing for easy relocation.
Innovation Solution
The use of rotatably attached weighted rollers or drums mounted on the rear framework of the goal, which provide stability and facilitate movement for maintenance, relocation, and storage, and can be tailored in number and size to accommodate various goal types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If stakes or augurs are used to secure the goal to the ground, then the goal stability is improved, but the ease of relocation deteriorates
Solution Approach 1:
The patent uses movable weights that can be positioned at different locations along the goal frame rather than fixed anchoring. The weights can be easily moved to adjust stability or removed for relocation, providing dynamic adaptability between stable operation and easy relocation needs.
2Stability of the object's composition
If weights such as sandbags are used to prevent tipping, then the goal stability is improved, but the device complexity increases
Solution Approach 1:
The patent combines the stabilizing weight function with the existing goal frame structure by attaching weights directly to the frame members. This integration eliminates the need for separate sandbags or external weighting systems, reducing overall device complexity while maintaining stability.
3Stability of the object's composition
If more or larger rollers are used to stabilize lighter goals, then the goal stability is improved, but the weight of the moving object increases
Solution Approach 1:
The patent applies weighting selectively at specific locations on the goal frame where stability is most needed, rather than uniformly increasing the weight of the entire structure. This localized approach provides effective stabilization while minimizing overall weight increase.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively stabilizes soccer goals against tipping and shifting, allowing for easy relocation and maintenance, enhancing safety and usability while accommodating different goal sizes and weights.
Implementation Method 1
one or more weighted rollers or drums rotatably attached to or attachable to the rear framework of a goal
Implementation Method 2
the rollers not only stabilize the goal by providing added weight, they facilitate moving the structure on a playing field

AI summary
In a soccer goal consisting of a framework supporting a net arranged to trap a soccer ball passing through the mouth of the frame upon scoring a goal, a safety device for preventing the shifting of the framework from a playing field position or from tipping over from misuse or player impact consisting of a weighted roller attachable or attached to the rear of the framework and resting on the playing field opposite the mouth which roller is either permanently weighted by construction of a heavy material or is constructed of a sealed shell fillable with a liquid such as water or a flowable particulate substance such as sand. In addition to providing the necessary weight to stabilize the goal, the rollers facilitate the repositioning of the goal for storage or to clear a playing field for other purposes.
