Solution Overview

Problem

Existing resistance training devices for ice hockey and similar sports lack the ability to deliver consistent, measurable resistance, accurately measure force/velocity, and provide recorded data, especially considering the unique challenges of training on ice with skates and the need for sport-specific equipment.

Innovation Solution

A resistance training device (RTD) that applies defined resistance to on-ice skaters through a line connected to an athlete, using a motor-controlled, battery-powered system mounted to a dasher board, capable of varying resistance and recording data wirelessly for analysis, and is portable for use in any ice arena.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional resistance training methods (weighted sleds, weighted clothing, partnered resistance bands) are used, then some level of resistance can be provided, but the resistance is inconsistent and cannot be measured or tracked

Engineering Contradiction:

Improveconsistency of resistance deliveryVSAvoidability to measure force/velocity

Core Design Contradiction:

ReliabilityVSMeasurement precision

Solution Approach 1:

The patent replaces traditional mechanical resistance systems (sleds, bands, body weight) with an electronically controlled resistance device that uses a motor, encoder, and control system to deliver precisely measured and consistent resistance forces, enabling both reliability and measurement precision simultaneously

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The device incorporates real-time feedback through encoders and sensors that continuously monitor resistance force and velocity, allowing the control system to adjust and maintain consistent resistance delivery while providing measurable data for tracking performance

Inventive Principle:

Principle #23Feedback

2Adaptability or versatility

If resistance training is performed on ice with skates, then sport-specific training can be achieved, but the unique footwear and ice surface create limitations for traditional training devices

Engineering Contradiction:

Improvesport-specific training capabilityVSAvoiddifficulty of using traditional devices on ice

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The resistance training device is designed with universal applicability to ice skating by incorporating a skate-compatible attachment system that can be securely fastened to skate boots, allowing the same device to function across different ice skating disciplines and training scenarios

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent introduces an intermediary attachment mechanism that connects the resistance device to the skate, serving as a mediator between the training device and the unique skate footwear, thereby enabling easy operation on ice without modifying the skates themselves

Inventive Principle:

Principle #24Intermediary (Mediator)

3Object-affected harmful factors

If a resistance training device is mounted to the dasher board, then the device can be positioned out of harm's way on the ice, but the device must be portable for use in any ice arena

Engineering Contradiction:

Improvesafety of athleteVSAvoidportability of device

Core Design Contradiction:

Object-affected harmful factorsVSWeight of moving object

Solution Approach 1:

The resistance training device is divided into modular segments including a mounting bracket, main body, and power system that can be easily assembled and disassembled, allowing the device to be safely mounted to dasher boards while maintaining portability for transport between arenas

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The device incorporates adjustable parameters including mounting position and resistance levels that can be modified based on the specific arena and training requirements, enabling flexible deployment while maintaining safety through secure mounting options

Inventive Principle:

Principle #35Parameter changes

AI summary

A training assembly comprising a resistance training device (RTD), an athlete, and a coach. In preferred embodiments, the RTD is used in conjunction with a skating rink and is secured to the dasher board of the rink by use of a mount system. A first end of a line extends from the RTD from an electronically controlled motor driven drive spool. The opposed end of the line is coupled to an athlete such as a hockey player to provide resistance to the athlete as they skate across the ice rink. The RTD can be configured to not only vary resistance, but also to collect data relative to the athlete's performance against the line tension. The RTD can be configured to move between an operable configuration and a folded configuration while remaining mounted to the dasher board. A rechargeable battery is located on board the RTD to drive the motor.
