Racquet design and tech - which company is likely to leap ahead of the others ?

First brand to implement AI in their frames?
These are 2 examples creating tennis frames with Bing AI Image Create with very few specs written in the discription. I can only imagine what more one can create from scratch using AI. If I have understood the way this programme works, any of these creations can (or are) be completely genuine. You can create anything from scratch. No way some brand can come to you and say: "this is my mold".

Bévels look a little round to me. Need to add to the AI input.

Yes, the discription I've input was just a few short and generic phrases to see what's gonna be the outcome. The more precise is the description, the better the result. Just sharing 2 more to see that the molds created are way different from one another. Actually, they are unlimited even when you re-push "Enter" with the same instructions, the results will be 4 different molds.

Closest things to the reverse shift would be the Prince Original Graphite OS (cross bar stiffens against lateral bending), and the Wilson Prostaff 85 (17mm box beam is wide aspect ratio).

Not coincidence these are iconic frames still being made 35 years later.

Layup design is a black box to me. I’ve tried long and hard to figure out how companies approach designing the pattern of the prepreg layers. Are there general guidelines and principles that everyone follows? How does one become a racquet designer or engineer?

Early layups seem to have been about the choice between unidirectional (not woven) pre-preg, woven layers and braided in a few cases, with a focus on creating something that doesn't break! Then the number and ordering of the graphite, fibre-glass and kevlar layers, following the knowledge that was built up making other products, became a differentiator. Then as the trend moved to larger frames, weight was reduced by lowering the number of layers and strategically reinforcing some points only, and adding dampening materials rather than full dampening layers or foam filling. What we have today is a continuation of that with the assistance of computer modelling to check the stresses and harmonics before baking anything. I guess the options regarding the type of materials and their costs are fairly well known in the industry today.

Do you know how of any sources where I can find example CAD drawings for layup patterns? I’m curious whether all the main manufacturers use a common design, or a set of designs, and modify them in-house …

Techs I’d like to see:

1. Reverse Shift
2. Bring back Prince Morph Beam
3. Bring back Prince More grommetless (NXG(

No I don't know, I've just seen Babolat, Tecnifibre, Artengo and Head using what look like bespoke CAD packages. They may have started as a common software though.

I'm fairly sure that actual CAD drawings are the one thing they don't release. As soon as anything looks good, they probably patent the layup. But if you did a engineering design degree, you'd probably be able to get pretty close to the process.

Regarding the process, they all say they have a super-duper team of inspirational geniuses who have carte-blanche to create the perfect hitting machine each time. However, I suspect they actually start with about 90% of the parameters already set and just play around until something new looks promising.

My impression is that this is also a tactic that the Wilson 4.7/5.7/6.7 employs, possibly better executed. Wilson labeled it "Rectangular Geometry".
The 4.7/5.7/6.7 employed a unique combo of a relatively dense pattern in the center (for good launch angle control) with generous stringbed real estate (high twistweight) and a bit higher sw than most game improvement frames. It’s puzzling why this combo is so rare, when clearly it’s what most rec players need.

Are environmental considerations during the manufacturing process to be considered in the discussion? I assume the production methods, raw materials used can/could lead to curtailing some innovation or move production to parts of the world with lax environmental regulations to get a finished product to market?

Are you talking about factory conditions or the final product? Rackets don't have any original manufacturing besides creation of molds. They are merely assembled from standard components like carbon fiber sheets, epoxy resin, foam, glue, wood, leather, plastics and paint. Any improvements in the manufacturing of those parts carry over.

To some extent, they use 3D CAD models.
