A trainer for practicing a proper cricket bat swing is shaped like a conventional cricket bat. A cavity with parallel side walls and toe and shoulder end walls extends through the trainer from its face to its swell. A weight freely reciprocates on a shaft aligned on the longitudinal axis of the cavity. The toe end of the cavity blocks sliding of the weight at the “sweet spot” of the trainer. When the trainer is swung in cricket bat fashion, the weight slides distally from the shoulder end wall and strikes the toe end wall of the cavity, providing audible indication of whether the contact of a conventional cricket bat with a bowled cricket ball would have occurred before, at or after the optimal ball-striking moment.

The invention relates to a pickleball paddle having an enlarged head resulting in an enlarged sweet spot area. The enlarged head includes a perimeter edge defined by a top edge and left and right curved side edges that extend from the top edge to a base end. A horizontal axis line extends through the left and right curved side edges to define the maximum width of the head. A sweet spot area is located approximately two thirds the height of the head from the base end, and the horizontal axis line is positioned to extend through the sweet spot area. An edge guard extends over the perimeter of the head and avoids the creation of any overlap segment or bulge to preserve usable handle length. The invention also relates to an edge treatment for dampening vibrations and adding weight to the pickleball paddle.

A test fixture for identifying the sweet spot of a bat includes one or more vibration absorbers, which may include cuffs, caps, and cuff / accelerometer combinations. An impact mass driven by motors strikes the bat at a series of locations along the barrel of the bat while the magnitude of vibration at the handle of the bat is measured by an accelerometer. The sweet spot is identified based on the minimum of the maximum measured acceleration values. The vibration absorbers inhibit gross movement of the bat and accelerate quiescence of oscillatory vibration of the bat between strikes, thereby reducing test time and increasing accuracy.

A method of optimizing a swinging implement, such as a bat, includes receiving an initial location of a sweet spot of the implement; receiving a contact point distribution for real-world usage of the implement; and performing at least one iteration of an optimization process to improve alignment between the sweet spot of the swinging implement and the contact point distribution. The optimization process involves adjusting one or more attributes of the implement (such as dimensions, shape / profile, and / or material properties) and computing an adjusted location of the sweet spot of the implement. The optimization process can iterate until alignment between the sweet spot and the contact point distribution is maximized. Attributes may be adjusted manually (e.g., by a user) or automatically (e.g., via mathematical optimization techniques executed in a processor). A design file for the optimized design may be output and used to manufacture optimized swinging implements.
