Collapsible Pitching Net Frame with Pivot Joints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for compact, portable support devices for sports equipment like nets that can easily be set up and stored, offering a solution for outdoor and indoor use while preventing stray balls from escaping.
Innovation Solution
A collapsible frame device with pivotally connected arcuate members and handles, allowing the frame to transition between open and closed positions for easy setup and storage, featuring a base with pivotally connected legs and pads for stability and a foldable net with apertures of differing circumferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the frame is made collapsible with pivotally connected members, then portability and ease of storage are improved, but device complexity increases
Solution Approach 1:
The frame is divided into multiple arcuate members (front arcuate members, rear arcuate members) that can pivot relative to each other, allowing the frame to be collapsed into a compact configuration for portability while maintaining structural integrity when deployed
Solution Approach 2:
The frame employs pivot joints that enable dynamic transformation between open and closed positions, allowing the structure to adapt its configuration based on operational needs versus storage requirements
2Ease of operation
If the frame is made collapsible for portability, then ease of transport is improved, but stability when deployed may worsen
Solution Approach 1:
Locking mechanisms are pre-positioned on the arcuate members to automatically engage when the frame is opened, ensuring stability is established immediately upon deployment without requiring additional assembly steps
Solution Approach 2:
The arcuate (curved) shape of the frame members provides inherent structural rigidity and distributes forces evenly across the frame structure, enhancing stability while maintaining the ability to collapse
