Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing swing training devices have limited adjustability of force, sudden high centripetal force, and lack versatility, which can be undesirable for improving swing movements in sports and exercises.
Innovation Solution
A swing exercising apparatus with a movable weight component that moves along an elongated member, utilizing a biasing mechanism with elastic elements to provide adjustable resistance and a return mechanism to control deceleration, allowing for customizable force and smoother weight return.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a weight is slidably mounted on a shaft with a stop at the end, then the device provides resistance during swing movement, but the weight stops very abruptly imparting sudden high centripetal force to the user
Solution Approach 1:
The patent applies beforehand cushioning by introducing a deceleration mechanism that gradually reduces the weight's speed before it reaches the end of the shaft. The deceleration portion creates increasing frictional force as the weight approaches the endpoint, cushioning the stop and preventing sudden high centripetal force from being imparted to the user.
2Force
If a spring is mounted to the weight and shaft end to provide resistance, then the device creates force during swing movement, but the adjustability of the force is limited and not versatile
Solution Approach 1:
The patent applies dynamics by making the resistance force adjustable and variable during operation. The deceleration mechanism allows the frictional force to dynamically increase as the weight approaches the endpoint, and the system can be configured with different friction coefficients or deceleration profiles to provide versatile force characteristics for different training needs.
3Power
If the weight moves along the shaft during swing, then centrifugal force displaces the weight to improve speed and power, but the device complexity increases with additional mechanisms
Solution Approach 1:
The patent applies this principle by using a friction-based deceleration mechanism that can be implemented with simple friction surfaces or friction pads rather than complex mechanical components. This flexible approach to creating deceleration force maintains the simplicity of the overall device while achieving the desired power improvement through controlled weight displacement.

AI summary
A swing exercising apparatus which can be used for improving a swing movement performed when practicing a sport or for other exercising purposes. The swing exercising apparatus comprises: a handle portion for grasping by the user; an elongated member having a distal end; a movable weight component for moving along the elongated member between a first position and a second position when the user swings the swing exercising apparatus, the movable weight component being closer to the distal end in the second position than in the first position; and a biasing mechanism comprising at least one elastic element for exerting a force biasing the movable weight component towards the first position when the movable weight component is located away from the first position along the elongated member. The biasing mechanism may comprise an attachment portion to attach the at least one elastic element, the attachment portion allowing the user to detach any of the at least one elastic element to adjust the force. The swing exercising apparatus may comprise a return mechanism comprising at least one elastic element for exerting a second force contributing to return the movable weight component towards the first position when the movable weight component compresses the at least one elastic element of the return mechanism.
