Mobile Training Device Bi-Directional Elastic Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing training devices for sports like baseball, tennis, and golf fail to effectively improve hip rotation and lower body strength, often being complex, costly, or impractical for field training, and typically provide resistance along only one axis without addressing vertical strength.
Innovation Solution
A mobile training device with an upright frame, base, and elastic ropes that provide bi-directional resistance by engaging with a training belt at an angle, allowing adjustable and variable resistive forces to be applied simultaneously in both horizontal and vertical planes, enhancing hip rotation and lower body strength training.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If weight is added to different parts of the training device to work a particular part of the body, then the training effectiveness is improved, but the device complexity and cost increase
Solution Approach 1:
The patent uses elastic ropes with variable resistance properties instead of fixed weight additions. The resistance can be adjusted by changing the elastic rope properties or configuration, allowing the same device structure to provide different training intensities without adding complex weight mechanisms.
Solution Approach 2:
The elastic ropes provide dynamic resistance that adapts to the user's movement. The resistance force changes automatically based on the stretch distance and speed, eliminating the need for static weight adjustments and complex resistance mechanisms.
2Device complexity
If a device provides resistance only along one axis, then the device structure is simplified, but the training effectiveness for multi-directional strength is reduced
Solution Approach 1:
The patent introduces resistance in multiple dimensions by using elastic ropes that can be configured at different angles. The ropes can provide resistance in horizontal, vertical, and diagonal directions simultaneously, transforming a one-dimensional resistance system into a multi-dimensional training solution.
Solution Approach 2:
The device combines multiple resistance directions into a single integrated system. By positioning elastic ropes at different angles and attaching them to the same training belt, the system merges horizontal and vertical resistance provision into one unified device that addresses multi-directional strength requirements.
3Ease of operation
If a device is designed for field training with easy setup, then the ease of operation is improved, but the resistance capability and stability may be reduced
Solution Approach 1:
The device uses localized elastic rope attachments at specific points on the training belt to provide concentrated resistance where needed. The elastic ropes are attached at strategic locations to maximize resistance effectiveness while maintaining simple setup procedures.
Solution Approach 2:
The elastic ropes automatically adjust to the user's movement and provide self-regulating resistance. The system requires no external power source, adjustment mechanisms, or complex setup - the elastic properties of the ropes themselves provide the resistance capability.
