Lacrosse Goal Frame With Hinged Base And Rod-Attached Net
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional athletic goals are cumbersome to assemble and require multiple people, with netting that is time-consuming to attach and prone to becoming loose, necessitating frequent restringing.
Innovation Solution
A goal frame with hinged base members and a net with sewn pockets that can be easily installed by passing securing rods through rings or eyelets on the frame, eliminating the need for intricate stringing and providing a uniformly tight fit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional netting methods with rope or twine are used, then the net can be attached to the frame, but the assembly is time-consuming and requires meticulous stringing to avoid gaps
Solution Approach 1:
The net attachment system is divided into discrete components: a net with pre-formed loops at regular intervals and separate rods that pass through these loops. This segmentation allows for faster assembly compared to traditional continuous stringing methods, as each rod can be independently positioned and secured through pre-formed attachment points rather than requiring continuous meticulous lashing.
Solution Approach 2:
The net is pre-prepared with loops or eyelets formed at regular intervals along its perimeter before assembly. This preliminary formation of attachment points eliminates the need for on-site stringing operations, significantly reducing assembly time while ensuring consistent spacing and tightness throughout the net attachment process.
2Reliability
If traditional stringing methods are used, then the net can be secured to the frame, but the process requires two or more people and is cumbersome
Solution Approach 1:
The net security system uses discrete rods with attached fasteners that can be independently manipulated and secured. Each rod can be separately inserted through corresponding loops in the net and anchored to the frame, allowing a single person to perform the entire attachment process without requiring coordination between multiple individuals.
Solution Approach 2:
The net attachment system is designed to be self-securing through the rod and fastener mechanism. Once the rod is inserted through the net loops and engaged with the frame attachment points, the system automatically maintains tightness and security without requiring continuous manual adjustment or coordination between multiple people during the assembly process.
3Reliability
If traditional net attachment is used, then the net can be tied to the frame, but repairs are often needed before, during, and after sporting events
Solution Approach 1:
The net is pre-formed with uniformly spaced loops or eyelets at regular intervals along its entire perimeter during manufacturing. This preliminary preparation ensures consistent attachment points that maintain uniform tension distribution when rods are inserted, preventing sagging and reducing the likelihood of damage during play, thereby decreasing maintenance frequency.
Solution Approach 2:
The attachment system changes the physical parameters of net attachment by using rigid rods with fasteners instead of flexible rope or twine. This parameter change creates more durable attachment points that resist wear and tear during sporting events, reducing the frequency of repairs needed while maintaining net integrity throughout the season.
4Reliability
If the net is tightly fitted to the frame, then no gaps or openings exist, but the tightness is entirely dependent on the skill of the person tying the net
Solution Approach 1:
The net is pre-prepared with uniformly spaced loops or eyelets formed at regular intervals along its perimeter during manufacturing. This preliminary action ensures that attachment points are pre-positioned at optimal locations, eliminating the need for skill-based judgment during assembly and ensuring consistent, uniform tightness throughout the net-frame connection regardless of the assembler's experience level.
Solution Approach 2:
The traditional skill-based mechanical process of hand-tying and lashing the net is replaced with a standardized rod-and-fastener insertion system. This substitution transforms the assembly process from a skill-dependent manual operation to a standardized mechanical procedure that produces consistent results, ensuring uniform net tightness without requiring高超 skill or experience from the assembler.

AI summary
The disclosure provides embodiments of a goal frame and net suitable for use in the sport of lacrosse and other sports. An upper frame portion typically includes a top horizontal crossbar connecting two vertical front posts. A second piece of the goal structure typically includes a base frame portion which can be formed from, for example, two elongate structural members (e.g., flat metal bars) connected to and terminating at a hinge which can be selectively opened into a “V” shape. A plurality of rods can pass through a number of pockets sewn around the perimeter of the net and tubular sleeves of the upper and lower frame portions about the perimeter of the frame creating an assembled goal with a net.
