Slotted Cylindrical Stick Trainer for Rotational and Fixed Drills
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing training devices for stick-based sports, such as hockey and lacrosse, are limited in their versatility, as they either allow for loose hand rotation but not fixed positioning, or vice versa, and often do not accommodate sticks with varying diameters due to grip tape or knobs, restricting their use in different drills.
Innovation Solution
A cylindrical training device with a flexible material that can be adjusted between a loose and fixed position, featuring a slot for universal fit and a fastening mechanism to accommodate different stick diameters, allowing for both stick handling and shooting drills.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rigid tubular structure is used to simulate a loose hand, then rotational movement during stick handling is enabled, but the device cannot be used for shooting drills requiring fixed position
Solution Approach 1:
The training device incorporates a flexible material body that can be selectively compressed between a loose state (allowing rotation for stick handling drills) and a fixed state (preventing rotation for shooting drills). This dynamic transition enables the device to adapt its stability characteristics based on the specific drill being performed, resolving the contradiction between rotational freedom and positional stability.
Solution Approach 2:
The device changes its physical parameters (rigidity, diameter) through user compression. When compressed, the flexible material transitions from a loose cylindrical shape that permits rotation to a compact fixed shape that prevents rotation. This parameter change allows the same device to serve multiple drill types with different stability requirements.
2Reliability
If a fixed diameter tubular structure is used, then the device provides consistent rotational training, but it cannot accommodate sticks with varying diameters due to grip tape or knobs
Solution Approach 1:
The training device uses a flexible material body that can be compressed to reduce its diameter. This flexibility allows the device to be placed over sticks with varying diameters, including those with grip tape or knobs, while maintaining consistent training characteristics once compressed onto the stick.
Solution Approach 2:
The device exhibits different physical properties in different states: in its uncompressed state it has a larger diameter for easy placement, and when compressed it has a reduced diameter that provides consistent rotational training. This local quality variation through compression enables both stick compatibility and training consistency.
3Ease of operation
If the device is made loose to enable rotation, then stick handling training is effective, but the stick cannot be securely held for shooting drills
Solution Approach 1:
The device transitions dynamically between a loose state (providing rotational freedom for stick handling) and a compressed fixed state (providing secure grip for shooting). The user controls this transition by applying compression force, allowing seamless adaptation between training modes requiring different grip strengths.

AI summary
A device for use in training activities for stick-based sports. The device is comprised of a generally rigid material provided in a generally cylindrical configuration. The device can have a first end and a send end that can define the length of the device. A slot can be formed between the first end and second end forming a first edge and second edge. An apparatus, such as a stick, can be positioned within an interior cavity of the device by inserting the stick through the slot allowing the device to be removably coupled to the apparatus. One or both ends of the device can have a flared portion. The flared portion can provide a better grip to a user as well as ensure smooth movement of the device along the apparatus.
