Hip Rotation Training Belt With Sliding Anchor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing swing training devices do not effectively encourage hip rotation during sports activities like baseball and golf, which is crucial for generating power and distance in swinging techniques, and they often lack simplicity, cost-effectiveness, and durability.
Innovation Solution
A swing training device comprising a belt with a restraint device and an anchor system that allows for slidable movement along the belt, tethered to a stationary object, which encourages hip rotation by sliding from the rear hip to the center of the backside during a swing, promoting proper technique and muscle memory.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If resilient cords or tethers are used to resist hip movement, then hip rotation is prevented, but the device complexity increases and manufacturing cost rises
Solution Approach 1:
The patent extracts the essential function of preventing hip twisting from complex resilient cord systems and reduces it to a simple slideable ring mechanism on a straight line. The ring slides along a line attached to the belt, providing restraint without the complexity of cords, springs, or multiple attachment points.
Solution Approach 2:
The invention uses inexpensive, simple components - a straight line (which can be a simple strap or cord), a slideable ring, and basic attachment means. These components are much simpler and cheaper than resilient cords, torsion springs, or complex mechanical assemblies while achieving the same functional effect.
2Stability of the object's composition
If multiple straps and connectors are used to secure the belt, then the belt stability improves, but the ease of manufacture and operation decreases
Solution Approach 1:
The patent removes the complex arrangement of multiple straps, connectors, and adjustment mechanisms from prior art devices. Instead, it uses a single line with a slideable ring that attaches to the belt, dramatically simplifying both manufacturing and operation while maintaining functional effectiveness.
Solution Approach 2:
The slideable ring serves multiple functions: it provides the restraining force, allows movement during the swing arc, and can be easily attached and detached. This single component replaces multiple specialized components needed in prior art devices.
3Force
If torsion springs or complex mechanical assemblies are used, then hip rotation resistance is provided, but the device durability and cost-effectiveness deteriorate
Solution Approach 1:
The invention replaces durable but complex mechanical components like torsion springs with simple, inexpensive elements - a straight line and a slideable ring. While simpler, these components have no moving parts that can wear or fail, and can be easily replaced if needed, achieving durability through simplicity rather than complex engineering.
Solution Approach 2:
The patent extracts the force-resisting function from complex mechanical assemblies and implements it through the simple geometry and tension of a slideable ring on a straight line. The resistance to hip rotation comes from the tension in the line and the constraints of the sliding mechanism, not from springs or mechanical advantage systems.

AI summary
A device and method are provided for training a person to swing a bat or club while rotating the person's hips. The device includes a belt for attaching around a person's hips, a restraint device attached to the back side of the belt, and an anchor system slidably attached to the restraint device. The restraint device can be a nylon strap sewn to the back side of the belt. The anchor system comprises a flexible member, such as a rope, with a first ring attached at one end for slidable attachment to the restraint device. The other end of the anchor system can be tethered to a stationary object or held by a coach. A clip can be attached to the restraint device for limiting the extent of movement of the anchor system along the restraint device and for providing a reference point for swing training.
