Harness-Mounted Elastic Ball Training System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ball training equipment lacks versatility and freedom of movement, often requiring fixed installations and restricting user movement due to handle-based designs or ground-mounted equipment, which can be hazardous and limit training variations.
Innovation Solution
A portable training equipment with a ball attached to an adjustable elastic line and a telescopic rod system worn as a harness, allowing 360-degree movement without fixed installations, adjustable angles, and a bag integration for convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a ball is attached to a fixed installation via an elastic line, then the ball can be trained, but the user's freedom of movement is restricted and fixed installations are required
Solution Approach 1:
The fixed installation is segmented into portable components: a harness worn by the user and a separate ball assembly with elastic line. This allows the training system to be divided into movable parts that can be used anywhere without permanent mounting structures.
Solution Approach 2:
The user's body serves as the anchor point through the harness system, eliminating the need for external fixed installations. The harness distributes the load across the user's body, allowing the user to support the training equipment themselves while moving freely.
2Adaptability or versatility
If a handle is used to hold the ball, then the ball can be controlled, but the user's freedom of movement is restricted and grip slippage risk increases
Solution Approach 1:
The handle is extracted from the system entirely. Instead of requiring the user to hold a handle, the ball is directly attached to the elastic line which connects to the harness, eliminating the need for manual gripping and associated problems.
Solution Approach 2:
The elastic line acts as an intermediary between the ball and the user's body. It provides a reliable connection without requiring direct manual contact, distributing forces through the harness system rather than relying on grip strength.
3Ease of operation
If ground-mounted equipment is used, then the ball can be tethered, but user injury risk increases
Solution Approach 1:
The ground-mounted equipment is replaced by segmenting the anchoring function across the user's body through the harness system. This distributes the attachment points from a single ground location to multiple body points, eliminating hazardous ground mounts.
Solution Approach 2:
Instead of anchoring the equipment to the ground and having the user interact with it, the system is inverted: the user anchors the equipment to their own body and the ball follows. This reverses the traditional mounting approach and eliminates ground-related injury risks.
4Adaptability or versatility
If a net surrounds the ball, then the ball can be contained, but the equipment becomes bulky and restrictive
Solution Approach 1:
The surrounding net is extracted and replaced by an elastic line connection. Instead of enclosing the ball in a net, the system uses a direct elastic attachment that allows full spherical movement without restrictive surrounding structures.
Solution Approach 2:
The rigid or semi-rigid net structure is replaced by a flexible elastic line. This thin, flexible connection provides the necessary containment and control while allowing complete freedom of movement in all directions without bulkiness.
