Backstop Net System With Winch Tensioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modular soccer fields with sagging net roof portions restrict the shooting distance for players and may have other disadvantages, such as inadequate space and resource constraints for standard-sized fields.
Innovation Solution
A backstop net system comprising adjustable stanchions and winches that secure a net around the perimeter of the playing field, ensuring the net's roof portions remain parallel to the field edges, preventing the ball from escaping and maintaining optimal playing space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the net roof portions are allowed to sag inwards towards the playing field, then the net structure becomes simpler and easier to install, but the shooting distance for players is reduced
Solution Approach 1:
The patent employs adjustable stanchions with variable heights that can be dynamically configured to maintain the net roof portions in a taut, parallel position relative to the playing field. This dynamic adjustment capability allows the system to prevent net sagging while preserving optimal shooting distance, resolving the contradiction between structural simplicity and playing performance.
Solution Approach 2:
The stanchion heights are made variable rather than fixed, allowing the system to change the geometric parameters of the net structure. By adjusting stanchion heights, the net roof portions can be maintained at optimal distances from the playing field, preventing sagging that would reduce shooting distance while keeping the structure adaptable to different installation conditions.
2Area of stationary object
If a standard-sized soccer field is provided, then players have adequate space for various sporting activities, but adequate space may not be available in all locales
Solution Approach 1:
The playing field is divided into modular wall segments that can be assembled in different configurations. This segmentation allows the field to be scaled to fit available spaces in various locales while maintaining adequate playing area, resolving the contradiction between providing standard-sized field space and adapting to space-constrained locations.
Solution Approach 2:
The modular field system with adjustable stanchions and configurable wall segments creates a universal structure that can serve multiple purposes and adapt to different spatial constraints. The same basic components can be arranged to create fields of different sizes, making the system versatile enough for various locales while preserving adequate playing space.
3Reliability
If resources for maintaining a grass field are allocated, then the field provides an authentic playing surface, but there may not be the resources to take care of a grass field in some areas
Solution Approach 1:
The patent employs artificial turf or alternative surface materials that require minimal maintenance compared to natural grass. While not perfectly permanent, these surfaces provide reliable playing qualities without demanding the extensive ongoing resources needed for grass field maintenance, resolving the contradiction between surface quality and resource availability.
4Reliability
If the net is secured tightly to prevent balls from leaving the field, then ball containment is improved, but the net structure becomes more complex
Solution Approach 1:
The adjustable stanchion system provides dynamic control over net tension and positioning, allowing the net to be secured tightly for effective ball containment while maintaining structural adaptability. The ability to adjust stanchion heights and positions enables tight net securing without requiring overly complex fixed structures.
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 system effectively prevents balls from leaving the field, maintains a consistent shooting distance, and adapts to smaller spaces by using adjustable components, enhancing player experience and field usability.
Implementation Method 1
The first winch applies an outward force, with respect to the playing field, on the end of the main support pole of the first stanchion by shortening a length of the first line between the first winch and the end of the main support pole of the first stanchion

AI summary
A field may include a plurality of walls segments, stanchions, one or more goals, and one or more doors. A net may encompass at least a portion of a perimeter of a playing field of the field. The net may include a roof portion. An end of the roof portion includes a first end adjacent a base line and a second end a distance into the playing field. The second end of the roof portion is attached to two stanchions. A cable is attached between a winch it attached to the end of a main support pole of the two stanchions connected to the second end of the roof portion. The winch applies a force to the end of the main poles to prevent the main poles from bending inwards towards the playing field.
