Foldable Goal Frame Rotatable Support for Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable goals are complex and time-consuming to disassemble into a storable configuration due to their design, which hinders ease of use and storage.
Innovation Solution
A collapsible goal frame featuring a crossbar, goalpost members, a support member, and a rotatable attachment member with a flexible linker, allowing the support member to rotate and fold along the same plane as the goal face, simplifying disassembly and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If portable goals use tubular plastic materials to reduce weight, then weight is reduced, but disassembly complexity and time increase
Solution Approach 1:
The goal frame is divided into separate modular components (crossbar, goalposts, support members) that can be independently attached and detached. Each component has standardized attachment points that simplify the disassembly process while maintaining lightweight construction using tubular plastic materials.
Solution Approach 2:
The support members are designed with rotatable attachment members that allow dynamic movement between extended and retracted positions. This enables the support members to rotate about the goal face and fold along substantially the same plane, transforming the structure from a rigid to a flexible configuration that simplifies disassembly.
2Weight of moving object
If portable goals use tubular plastic materials, then weight is reduced, but disassembly time increases
Solution Approach 1:
The rotatable attachment members enable rapid transformation of the support members from extended to retracted positions through simple rotation about the goal face. This dynamic mechanism eliminates complex fastening and unfastening operations, significantly reducing disassembly time while maintaining the lightweight tubular plastic construction.
Solution Approach 2:
The attachment members are pre-configured with attachment collars and projections that automatically align and engage with the goal face and support members. This preliminary configuration ensures that disassembly requires only simple detachment motions without requiring complex manual manipulation, thereby reducing disassembly time.
3Strength
If the support member extends outwardly from the goal face, then structural support is provided, but storage space requirement increases
Solution Approach 1:
The support members are designed to be dynamically reconfigurable, extending outwardly from the goal face during use to provide structural support, then rotating about the goal face to fold along substantially the same plane for compact storage. This dynamic transformation allows the same component to fulfill both structural and space-saving requirements at different times.
Solution Approach 2:
When in the retracted position, the support members fold along the same plane as the goal face, allowing them to be nested or stacked in a compact configuration that minimizes storage volume while maintaining full structural capability when extended.

AI summary
A goal frame for a goal apparatus, the goal frame including a crossbar member, a first and a second goalpost member, a support member, and a rotatable attachment member. Respective ends of the crossbar member are attached to, or are operable to attach to, a respective end of the first and second goal post members to form a goal face. The attachment of the respective end of the crossbar member to the end of the first goal post member forms a crossbar-goalpost corner portion of the goal face. The rotatable attachment member is attached to, or is operable to attach to, the goal face adjacent to the crossbar-goalpost corner portion. The rotatable attachment member is attached to, or is operable to attach to, an end of the support member. The rotatable attachment member is operable to rotate about the part of the goal face to which it is attached from a first position in which the attached support member extends outwardly from the goal face to a second position in which the attached support member extends along substantially the same plane as the goal face.
