Solution Overview
Problem
Existing training devices lack a user-friendly design that can engage both individuals and groups effectively, failing to provide a versatile and interactive solution for improving athletic performance.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the arms are designed to extend laterally outwardly for training exercises, then the training effectiveness and engagement are improved, but the device becomes more complex and harder to handle
Solution Approach 1:
The arms are designed to be movable relative to the hub, transitioning between a closed state for easy handling and an open state for lateral extension during training exercises. This dynamic configuration allows the device to adapt between portability and training functionality.
Solution Approach 2:
The arms can be positioned in a closed state where they extend downwardly from the lower side of the hub, allowing the arms to be nested or folded close to the hub body. This nesting mechanism enables compact storage and easy handling while maintaining the capability to deploy arms laterally for training.
2Ease of operation
If the arms are made moveable to transition between closed and open states, then the ease of operation is improved, but the reliability of maintaining position may worsen
Solution Approach 1:
The elastic cords are configured to automatically bias the arms into the open state, providing self-servicing position maintenance. The elastic cords continuously exert force to return the arms to their operational position, eliminating the need for additional locking mechanisms or power sources to maintain position stability.
Solution Approach 2:
The elastic cords change the mechanical parameters of the arm system by introducing elastic force that counteracts gravitational and inertial forces. This parameter change enables the arms to maintain stable positions during training while allowing easy manual manipulation when needed.
3Adaptability or versatility
If elastic cords are used to bias the arms into open state, then the adaptability for training is improved, but the device complexity increases
Solution Approach 1:
The elastic cords provide self-servicing mechanical biasing that automatically returns the arms to the open state without requiring external power sources, controls, or complex actuation systems. This simple elastic mechanism achieves the desired adaptability with minimal added complexity.
Solution Approach 2:
The elastic cords introduce elastic force parameters into the system, creating a simple yet effective mechanism for maintaining arm position. This physical parameter change approach avoids the need for electronic controls, motors, or computer systems, keeping the device relatively simple while achieving training versatility.
