Wrist Position Training Device Haptic Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wrist training aids for sports swings, such as golf, fail to provide adequate feedback for proper wrist flexion during the swing arc, particularly at the point of impact, leading to inaccurate shots due to improper wrist positioning.
Innovation Solution
A wrist position training device featuring a haptic member that provides audible and physical feedback when the wrist transitions into and out of flexion, ensuring proper wrist positioning through a resiliently flexible design with a wrist band and anchor loop for secure fitting, allowing users to feel and hear a 'click' when the wrist is in the correct flexion position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wrist support device restricts extension movement to prevent breaking the wrist to the outside, then extension movement is controlled, but flexion movement cannot be trained or monitored
Solution Approach 1:
The patent inverts the traditional approach by providing haptic feedback for flexion movement rather than restricting extension movement. The haptic member is configured to engage with the user's hand to provide feedback when the wrist moves into flexion, allowing training of the previously untrainable movement while maintaining reliability for proper wrist positioning.
Solution Approach 2:
The patent introduces haptic feedback through a resiliently flexible member that provides tactile and audible signals when the wrist achieves proper flexion position. This feedback mechanism enables real-time monitoring and correction of wrist position during the swing arc, particularly at impact, without restricting natural movement patterns.
2Measurement precision
If a haptic member is made resiliently flexible to provide feedback during swing arc, then wrist position feedback is improved, but device complexity increases
Solution Approach 1:
The haptic member is designed to be self-activating based on wrist position during the swing. The resiliently flexible member automatically engages and disengages according to the natural arc of wrist movement, providing feedback without requiring external power sources, sensors, or complex control systems. The device uses the swing motion itself to activate the feedback mechanism.
Solution Approach 2:
The patent employs a thin, resiliently flexible member that can bend and flex with wrist movement. This flexible component provides haptic feedback through its physical properties alone, eliminating the need for electronic sensors, motors, or complex mechanical assemblies, thereby maintaining simplicity while achieving precise wrist position detection.
3Productivity
If the haptic member provides feedback throughout the entire swing arc, then comprehensive wrist training is achieved, but risk of over-flexion increases
Solution Approach 1:
The haptic member is pre-configured with specific engagement characteristics that prevent excessive flexion before it occurs. The resiliently flexible member's physical properties and geometry are designed to naturally limit the range of motion, providing resistance that stops further flexion once the proper position is reached, thereby preventing over-flexion as a preliminary protective measure.
Solution Approach 2:
The haptic feedback is provided at the precise moment of proper flexion position rather than continuously throughout the entire range of motion. The resiliently flexible member engages briefly to provide the feedback click and then disengages, allowing the swing to continue without constant resistance. This partial action provides necessary feedback while avoiding the harmful effects of continuous restriction.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device enhances the user's ability to maintain proper wrist positioning throughout the swing arc, providing positive reinforcement for correct alignment and preventing over-flexion, thus improving shot accuracy by ensuring the club face strikes the ball at the ideal angle.
Implementation Method 1
The haptic member is resiliently flexible such that it is bendable either upward or downward from a neutral position, and is configured so as to provide an audible and physical click when bent downward from the neutral position

AI summary
A wrist position training device for a sport swing includes one or more wrist wraps to secure a haptic member to the back of a user's wrist and hand. A first end of the haptic member is anchored to the user's forearm. A second end of the haptic member is secured to the back of the user's hand by a finger loop or similar structure so that the haptic member follows the user's hand as the wrist transitions from a neutral position to a flexion position. The haptic member produces a tactile and audible response when transitioning between the neutral and flexion positions. This tactile and audible response signals to the user when their wrist breaks and returns to neutral position.
