1. Putting for Perfection
By: Keith L, Logan D, James K, Patrick H, Eleanor M

2. Main Problems being Addressed
Consistent club velocity
Adjustable contact point
Adjustable face angle
Laser guidance
Dampening of vibrations

3. Adjustable Contact Point
With the current design the only way to change where the ball makes contact with the face of the putter is by picking the machine up and physically moving. This not only provides inaccurate results because there is no gauge but it is also hard to lift.
Solutions
Problems
A track system up where the club connects to the putter
Having a track sticking out could interfere with other moving parts
Installing a hinge up by the connection point to allow it to move forward or back
You wouldn’t be able to lock the hinge in a set position
Improving the current knobs that are suppose to work for this issue
When you use the knobs you not only change the face angle but you also change the height of the head off the ground
A track system at the bottom of the base
This is the most valid solution

4. Current Solution Proposal
As mentioned in the other slide the current solution we feel is the best is to install a rail and track system at the base of the machine.
Benefits
Allows contact point to be changed while keeping all other variables constant.
Being its on the base it will be easy to have a gauge system for accurate adjustments.
The track will need to be 5cm long and the base is big enough to accommodate that.

5. Vibrations
Sasho Mackenzie mentioned there may be slight vibrations between the grip and club handle.
Detailed slow motion video / motion capture must be performed to analyze vibrations in the putter grip and putter head.
A decision will be made to implement a solution once the frequency of vibrations is determined in the putter grip and putter head.

7. Vibration Damper - Sorbothane
Sorbothane is a proprietary, visco-elastic polymer.
Sorbothane’s operating range requires frequencies between 10Hz – 30000Hz.

8. Face Angle
Changing the face angle at which the club head hits the ball is what allows it to have both horizontal and vertical motion. Different test trials may need more motion in a certain direction, depending on the experiment.

9. Face Angle Solutions Solutions Problems
Very similar to the adjustable contact point issue. As of now, the face angle of the club can only be changed by either picking up the machine and rotating it, or by unscrewing the golf club, rotating it, then screwing it back into place. Both of these methods require tedious labour and are not precise enough to be considered without error.
Solutions
Problems
A ring clamp installed into the grip that holds the club. Carve out space inside the grip so the ring can only rotate
Very detailed work on the inside of the grip that holds the club. Would have conflicts if Sorbothane grip is implemented
Have a rotating disc mounted at the base of the mechanism
This is the most valid solution

10. Current Face Angle Solution
To accurately adjust the face angle of the club head, we are going with having a rotating disc at the base of the device. This disc will be a replica of the one at the top of the mechanism. When paired with the track system, it ensures that the contact point can be set to any desired position.
Benefits
Allows face angle to be changed while being able to control all other variables
Will provide an option for measurable, rotational movement (gauge)
The disc rotates smoothly so provides a continuous interval to choose from
Will not interfere with other planned installments
Design work for disc is already complete (replica)

11. Realistic Rotation Point
Current rotation point is too low it needs to be raised to simulate a real putter swing
Having a higher rotation point will help make the putter mechanism more life like
Will assist in making video capture more realistic

12. Solution to raising the rotation point
The height of the machine will have to be raised from .790 meters to a height of 1.5 meters
Location of grip will be moved to half way down pivoting arm
The whole machine will have to be rebuilt to solve this problem

13. Constant Club Velocity
Solutions
Benefits
Cons
Pin Release
- Can build off of the original design
- Simple and easy to implement
- Cheap
- Can cause misses meaning a retrial is necessary
- Requires lubrification
Catch and release mechanism
- Locks securely in place
- Easy to operate
- Most accurate
- Multiple components
- Button mechanism potential to cause some errors
- Expensive

14. Preferred Solution
After consulting with Dr. Mackenzie we are currently leaning more towards the solution of a catch and release ratchet. Although it will cost more it has a significantly better chance of achieving our goal of obtaining consistent swing speeds every time. Using a ratchet will allow for a measurement gauge to be implemented on the device, which will help ensure the club is being brought back and released at the same height every time.
