Double-Sided Goal Frame Assembly for Variable Team Sizes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ball game goals are not adaptable to different team sizes and ages, requiring multiple goals of varying sizes that occupy excessive storage space and are cumbersome to adjust, leading to instability and increased costs.
Innovation Solution
A double-sided goal with two interchangeable frames and connection bars that allow easy modification between different team sizes, featuring a net system to catch balls, reducing storage needs and simplifying transitions between team sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple goals of different sizes are purchased to accommodate different team sizes and ages, then the goal can be compatible with various team configurations, but the storage space required and cost increase significantly
Solution Approach 1:
The patent combines two separate goals of different sizes into a single integrated structure. The frame assembly includes a first frame with first dimensions and a second frame with second dimensions, both connected to form one unified goal structure that can serve multiple team sizes simultaneously, eliminating the need to store multiple separate goals
Solution Approach 2:
The goal structure is designed with universal functionality to accommodate different team sizes and ages. By incorporating multiple frames with different dimensions in one structure, the goal can be used for various team configurations (e.g., full-size for 11-player teams, smaller for youth teams), making it a multi-functional device that replaces multiple single-purpose goals
2Adaptability or versatility
If adjustable frame members are used to change goal size, then the goal can adapt to different team sizes, but the adjustment procedure becomes time-consuming and the goal stability decreases
Solution Approach 1:
The goal incorporates movable and adjustable components that allow dynamic reconfiguration. The connection means enable frames to be easily detached and reattached in different configurations, allowing quick adaptation between different team sizes without time-consuming adjustment procedures while maintaining structural stability through proper connection mechanisms
3Adaptability or versatility
If telescoping connections are used in the frame, then the goal can be adjusted in size, but the ball may bounce in unpredictable directions when hitting the connection
Solution Approach 1:
The frame structure is segmented into distinct rigid frame members connected by stable connection means. Rather than using telescoping connections within single members, the design separates the structure into discrete segments (frames and connection means) that maintain rigidity and predictability when balls make contact, ensuring reliable and predictable ball trajectories
4Volume of stationary object
If a double-sided goal with different sizes is created, then storage space is reduced, but the device complexity increases
Solution Approach 1:
The patent merges two separate goals into one integrated double-sided structure where the frames and connection means form a unified assembly. This combining reduces the number of separate devices to store while managing complexity through systematic design of the frame and connection components

AI summary
A goal (1) for ball games, which is compatible with different team sizes and different ages of players, comprises a first frame (4) defining a first substantially rectangular goal opening (2) facing in a first direction and a second frame (8) defining a second substantially rectangular goal opening (3) facing in a different direction. The second goal opening has a size different from the first goal opening. Connection means (12, 13, 14, 15) connect the frames to provide a frame assembly; and net means (16, 17, 18, 19) arranged to catch a ball passing through one of the goal openings (2, 3) are attached to the frame assembly. With two different goal sizes in a double-sided goal the required storing space for multiple goal sizes is considerably reduced, and the goal just needs to be turned around in order to be ready for a game with a different team size.
