Conceptual Designs

Single Arm Design

As stated before with the adaptive golf sleeve, our concepts have now shifted so that the user still has the ability to use their prosthetic hook attachments and they can use the device independently. The single arm design is an effective and simple solution for double arm amputees that allow them to have complete use of one of their arms at all times. A sketch of the single arm design can be seen below in Figure(10).

The sketch depicts a collar that would be attached onto the prosthetic arm, preferably the right arm. The collar would need to be attached to the arm of the user before playing golf and it would stay there throughout the round. Attached to the collar is a c-clamp that is attached to the collar via a bungee cord. The c-clamp is put in place in order to clamp onto the grip of the club. The user would then grip the shaft with their prosthetic hook. The bungee cord is applied between the collar and clamp to simulate the rotation of the wrist during the backswing. So when the user pulls the club back, the bungee cord extends at the top of the backswing creating lag in the downswing. This lag would then release at impact, the same way a traditional golf swing releases the club at impact.

One consideration for the single arm design is its safety. The c-clamp needs to be secured to the grip of the club extremely tight so that the momentum of the swing doesn’t force the club to fly out and potentially hit someone or injure the user. Besides this consideration, the single arm design always leaves the user with one prosthetic arm free to do whatever they want. It isn’t entirely independent since an outside party would need to attach the collar onto their prosthetic arm. But once the collar is attached it won’t need to be modified, and it becomes independent after that.

Adaptive Golf Glove

After finding out that independent use was more important to a bilateral amputee than a device that allowed for a typical golf swing, we had to brainstorm some new ideas. We wanted something that the user could easily put on and take off during a round of golf. The idea of a golf glove developed from learning about Jim Taylor’s secret to increase the surface area of the gripping point. The hooks normally have a gripping surface area of two or three square centimeters. A golf glove would simply slide on the hook just like a normal golf glove. At the end of the hooks, there will be a curved slot that the grip can fit into. The glove will not cover up the lever completely to allow for them to attach/detach their cables.

Figure 11 shows a sketch of the golf glove design and Figure 13 shows a sketch of the top view. Figure 14 shows what the amputee would look like at address. This design quadruples the normal gripping surface area of the hook. If the amputee detaches his cables from the lever, there will be a very strong gripping force on the club and the club will not fly out of his/her hands. It is undecided what material the glove will be made of because the hooks can easily rip any cloth like material.
