Collapsible Game Goal Frame with Snap-Fit Joints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Collapsible field game goals are often less rugged than their non-collapsible counterparts, compromising durability while providing the advantage of a smaller footprint for transport and storage.
Innovation Solution
A collapsible game goal design featuring a support frame with rigid members and mechanical joints that snap fit into place, allowing the frame to expand into a play-ready state and collapse into a storage-ready state without impeding the net's functionality, using corner brackets with tabs for secure alignment and elastomeric rods for flexible bending.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the game goal is made collapsible to reduce footprint for transport and storage, then the area and volume for storage are reduced, but the structural strength and ruggedness deteriorate
Solution Approach 1:
The support frame is divided into multiple rigid frame members (uprights, crossbar, base members) that can be segmented and reconfigured. Each member is connected through mechanical joints that allow the frame to collapse into a compact configuration for storage while maintaining structural integrity during play. The corner brackets with tabs and snap fits further segment the connection points, enabling controlled collapse without compromising overall strength.
Solution Approach 2:
The support frame transitions from a static fixed structure to a dynamic collapsible structure. Mechanical joints are interposed between rigid frame members to allow relative displacement, enabling the frame to expand into a play-ready configuration and collapse into a storage-ready configuration. This dynamic capability reduces storage volume while maintaining strength during use through proper engagement of locking mechanisms.
2Ease of operation
If mechanical joints are used to enable collapsibility, then the ease of operation and storage are improved, but the device complexity increases
Solution Approach 1:
The mechanical joints are designed to automatically lock and unlock without requiring external tools or complex mechanisms. Corner brackets with tabs engage with corresponding slots on rigid frame members through snap fits, allowing the structure to self-lock in the expanded configuration and self-collapse when force is applied. This self-service mechanism simplifies operation while controlling complexity by eliminating the need for additional locking devices or complex control systems.

AI summary
A game goal includes a net and a support frame by which the net is supported. The support frame is articulated to collapse into a storage-ready state and expand into a play-ready state. The support frame is further selectively retained in the game-ready state by a snap fit on each of opposing sides thereof.
