Solution Overview
Problem
Conventional sport training structures with step training loops are not fixed, leading to positional changes, inconvenience in rearrangement, and increased volume when not in use due to fixed sizes and inability to be folded, making storage and transportation difficult.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If step training loops are made fixed in size and shape, then training effectiveness is improved, but storage and transportation volume increases
Solution Approach 1:
The training loop is divided into multiple rigid polygonal frames that can be segmented and connected through pivot members. Each frame maintains its rigid structure for training effectiveness, while the connection pivots enable folding for compact storage.
Solution Approach 2:
The structure incorporates dynamic pivot connections between rigid frames, allowing the system to transition between an expanded configuration for training and a folded configuration for storage. The pivot members enable controlled movement while maintaining structural integrity.
2Stability of the object's composition
If step training loops are made non-foldable with determined sizes, then structural stability is improved, but ease of storage and transportation deteriorates
Solution Approach 1:
The training loop is segmented into multiple rigid polygonal frames connected by pivot members. Each frame maintains its rigid structure for stability, while the pivot connections enable folding for easy storage and transportation.
Solution Approach 2:
The structure uses dynamic pivot connections between rigid frames, allowing transition between expanded (stable) and folded (compact) configurations. The pivot members enable controlled movement while maintaining structural integrity during both states.
3Ease of manufacture
If step training loops are made without fixing mechanisms, then ease of assembly is improved, but positional stability deteriorates
Solution Approach 1:
The structure employs pivot connections that provide dynamic stability - the frames can be easily assembled and disassembled through simple pivot movements, yet maintain positional stability when deployed. The elastic pivot members provide natural resistance to displacement while allowing controlled adjustment.
Solution Approach 2:
The elastic pivot members provide self-centering and self-stabilizing properties through their elastic deformation characteristics. When frames are assembled, the elastic pivots naturally settle into stable positions, providing positional stability without requiring additional fixing mechanisms.
4Reliability
If multiple training tools are constructed with fixed structures, then training functionality is improved, but adaptability for different configurations deteriorates
Solution Approach 1:
The structure uses dynamic pivot connections between rigid frames, allowing transition between expanded (functional) and folded (compact) configurations. The pivot members enable controlled movement while maintaining structural integrity during both states.
Solution Approach 2:
The same rigid frames and pivot members can be configured to form different polygonal shapes and sizes, providing multiple training configurations. The universal connection design allows the structure to adapt to various training needs while maintaining structural reliability.

AI summary
A sport training structure includes a plurality of brackets and a plurality of first pivot members connected with the brackets. Each of the first pivot members has two connecting portions. Two of the first pivot members are mounted between two of the brackets to construct a polygonal frame, with each of the two connecting portions of each of the first pivot members being pivotally connected with one of the two pivot ends of each of the brackets. In such a manner, the two of the brackets are pivoted about the two of the first pivot members, so that the polygonal frame is foldable.
