Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Golf bag system is in its final design iterations
Conducting user testing to improve consumer assembly experience
Accomplishments from Previous Week
Moved the middle fastener belt up towards the connector
Wrote version 1 of the assembly manual
Asked 6 people in Price Center to test the prototype
See uploaded files in Reports --> Docs
Goals for Next Week (list names after each item). Use specific and measurable objectives.
For the manual
Use CAD image to replace the hand drawing in the manual
Break down step 5 in manual to make it more clear
Integrate step 1-4 and make descriptions more concise
Limit the size of manual to 1 page
Illustrate the correct orientation of lower stand (step 6) more clearly
Including marking the sides that should join together, or make non-square stand to avoid confusion.

Meeting with Ronan in person 2/1/20
(next interview scheduled for Thursday 2/19, since Ronan is out of town this weekend)
-Ronan likes the design so far, says it almost assembles itself
-Ronan noticed its very unstable compared to original golf bag, wobbles a lot
-Since there’s no stand bracket that’s why it wobbles
-we are looking for solutions to this issue
-if we extend the rigid piece to 1/3 of bag length, then the angle of wobbling would be less
-golf clubs inside would improve the experience, make it more stable
-Ronan placed some golf clubs inside to test it out
-can’t wobble as much because the length of the golf club stops the bag form moving around as much
-if we add the stand bracket back in, then we would have to add another piece that has to be assembled
-user has extra step added, another part to assemble
-current stand isn’t fully rigid since it isn’t directly connected to the base of the bag
-we know cost-wise which one would be better
-don’t know which one the consumer will prefer
-problems with first bag design
-circular stand bracket à rotation and unstable/can fall
-this was solved by using square rod for stand system
-Ronan says we should focus on this system, less work for consumer is better
-tent pole stand bracket will increase price compared to current prototype price bc there’s another rod of metal
-Ronan says to stick with option one, don’t add tent pole stand bracket
-used a string to be a limit link to limit angle of legs
-marketing: need to show consumer that the wobbling isn’t a problem once the golf clubs are in
-current shipping box size is: 35 in x 6 in x 8 in
-currently 14 in in length when folded
-current volume would be about 14 in x 6 in x 8 in
-really nice golf bag goes for about $200, that’s much more than ours
-$1500 – 2000 for a new set of golf clubs, so price of this $30-40 bag isn’t much for user
-manufactured product would weigh less, would use thinner metal
-would also be more aesthetically pleasing, we used tape etc
-we use aluminum, but can use cheapest metal
-can use better string for limit links
-unsure about wear test, rubber band inside legs is problem
-go on Alibaba? Contact rubber band factories and ask them what the lifespan is for bands
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Meeting with TA in person on 2/13/20
-moved strap to the top portion, 1/3 from the top
-where the frame ends
-2 connection points at top and bottom of bag connect stand and bag
-frame supports the bag so it doesn’t deform
-still doesn’t solve that stand and bag separate when you shake the bag
-strap will make bag less wobbly
-customer first checks to make sure bag is working right/stable
-strap should decrease wobbliness
-also added a band around the bag when its folded
-to keep it tight in the container
-all straps were added this week
-straps were sealed onto the bag
-keep pushing on presentation side
-need to have a good way to sell product at the final presentation
-we have good understanding
-at intro part, want to introduce w shipping price
-do some literature review in terms of introduction
-this would make us better prepared and more confident
-draft a simple user
-ask other students to test the product
-ask someone who is non-engineering or who hasn’t seen this so far
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
Comments from students who tested the prototype (2/19 in person)
Most people found step 4 and 5 to be hard to understand though the manual. Some report that the manual is not drawn clearly
Most people don’t know how a golf bag should look like, or couldn’t identify the parts in the manual
Most people didn’t complete step 6, and half of them did step 5 wrong (wrong orientation or alignment)
One suggest that labelling the parts would help user identify them. One responded that the assembly itself is not challenging at all.
Risks and Areas of Concern
Need to make sure instructions are easier to follow
Have pictures that are easier to follow
Ask more engineering and non-engineering students for feedback
Need to get sponsor feedback on current design
Resources or Information Required but not Available
CAD Model for handle
CAD model for all components
How do they do wear tests and strength tests?
