Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the prior art device is used only fitted over the user's fingers, then it provides air resistance to the wrist, but it cannot induce arm bending and fails to simulate actual pitching
Solution Approach 1:
The device transitions from a static finger-fit structure to a dynamic hand-grip structure with movable components. The grip portion allows the user to hold the device like a baseball, enabling natural arm bending motion during pitching simulation, while the air resistance element dynamically adjusts resistance based on arm movement speed and angle.
Solution Approach 2:
The device changes the operational parameters from finger-size adaptation to hand-grip dimensions. The grip portion is designed with dimensions matching actual baseball size, and the air resistance element's orientation and resistance force are adjusted according to the arm's cocking, acceleration, and deceleration phases, accurately simulating real pitching mechanics.
2Device complexity
If the finger holding portion size is fixed in the prior art, then the structure is simple, but it may easily escape off the finger during pitching training
Solution Approach 1:
The stopping holder incorporates an adjustable mechanism that allows the opening size to be dynamically modified. Users can adjust the opening width to match their finger dimensions, and the anti-escape protrusion provides a mechanical stop that prevents the device from sliding off during pitching motion, combining simplicity with reliability.
3Device complexity
If the prior art provides only air resistance to the wrist, then the device is simple, but it cannot provide the feel of weight of a ball
Solution Approach 1:
The device is segmented into distinct functional components: a grip portion that simulates ball weight and handling, a stopping holder that secures the device, and an air resistance element that provides resistance. This segmentation allows each component to perform its specific function effectively while maintaining overall device simplicity.
Solution Approach 2:
The grip portion is designed with weight and dimensions that closely match actual baseball parameters, providing realistic weight feedback. The air resistance element's resistance force is calibrated to match the resistance encountered during actual pitching, creating a comprehensive simulation experience without excessive complexity.
4Device complexity
If the stopping hole is straight in the stopping holder, then the structure is simple, but the stopping holder cannot be securely seated on the finger
Solution Approach 1:
The stopping hole is designed with a curved path that follows the natural contour of the finger. This curved geometry allows the stopping holder to be securely seated on the finger by matching the finger's curvature, preventing slippage during pitching motion while adding minimal structural complexity.
