As part of my engineering course, I have to complete a project based from my own ideas.

I chose an engineering solution based on a guitar Capo. The solution was to be able to combine the uses of a full capo and a partial capo, by creating a capo with interchangeable parts. This would enable the user to customize which strings he/she wanted to cover.

I created the shape of the capo using 3D software and this is what I have came up with:



The capo is designed to have a rotational ratchet housed inside the pivot point, inside where the "cT" logo is placed. The black linings are the pads that will come in to contact with the neck and strings.

The interchangeable part is based off a computer keyboard key locking system, that with a bit of pressure it can be placed in and out of the capo, enough pressure inside so that it won't fall off, even though in place it will be clamped down on the strings.

Here is the design I came up with:



The images aren't to scale, and no dimensions have been set yet. These interchangeable parts will be placed in to the underside of the upper capo lip.

For my project I am required to do some market research, including target market research.

So I need some users here to give me some feedback, based just off the design and use of my capo. I am aware of some problems at the moment, however I still need feedback from the target market.

Bear in mind I don't need to build the components for my project.

Thank You

Edit:

I'm not good enough on the software to draw the exploded view of the ratchet yet, only just learning.

It will pivot from the bottom up towards the bottom side of the guitar neck, the ratchet means it will move freely towards the neck however once it moves up it can't be moved down without releasing it.

This will be the clamp

yeah but does it blend


on a more serious note, how do you open it?

so it clamps? like, you press it down on the strings, it will lock in place?
It's over simplified, So what!

He said it, Pivot point where the logo is. So yes, it clamps. Lrn2read

Seems lik a good idea in theory, but IMO theres too many small parts and things to go wrong to be useful and durable for a touring or gigging musician.

Maybe if youre still open to other ideas, a system thats built into the guitar like a floyd rose but that capos individual strings

That's a worse idea.

im sure you've seen the g7th.
(you'll notice, that design wise, you're might not realistically fit
around a headstock)




the issues, i can see already, being familiar with capos shaped like this,
is that there's no place to keep the capo when it's not being used.

so, when you're on stage, you have to keep it in your pocket.

yes, the g7th doesnt press too hard, and pull the strings out of tune, the way that a trigger
capo does.

but i cant use it during a set, because i need to be able to switch between songs.

additionally, you would need a tool ? or trigger? to engage the individual string pads on yours?

is that something can be done on the fly?

maybe you can add a guitar headstock mount?
that doubles as a tool to engage the pads?

good luck.

too many variables at this point in time. i understand what you are trying to do, but you have quite of bugs to work out. also for some reason, i am thinking that as it is now you could scratch the side of the neck.

edit: there are a lot of neck profiles out there, make sure it would work for anything and everything between a Gibson 50's neck and an Ibby Wizard profile.

Looks like a cool idea.

One problem I can see is that you could lose the interchangeable parts.

How about having individual pads for each string with a mechanism underneath that lets you lock the pad in the up position so it does not touch the string, then you could press it again so the pad locks in the down position where it will fret the string for you?

That way you'd have no removable parts that could get lost.

I think a simpler solution is to make just a capo for each neck profile. As mentioned earlier, there are quite a few components already, having one more component means one more thing tomgomwrong.

Btw TS, a key aspect of good market research is to collate all issues raises, categorise them as pros and cons, then list out solutions to each con and further developments to pros.

It's gotten to the point in my project that I can't afford to go back and change things, to go through my project I simply have to do some research, so any feedback, whether good or bad will help me pass my project.

All the negative feedback I can collate when writing my evaluations, so I thank everyone who has commented.

well maybe i have more info that can help, do you have any specific questions?

Looking for feedback on:

Aesthetics of the design,
Utility ( designed so that you can change the parts over easily, however this can't be done whilst the capo is clamped - problem )
Whether or not the idea is feasable/neccessary

Most important information I need at this moment.

does the capo move, or do just the pads engage?

and like said, trying to fumble with removable "parts" isnt at all practical.

Yes the bottom wedge clamps to the underside of the neck, I'm just not good enough with the software to draw it with the moving parts ( had to teach myself to use it )

Because of the size of capo the parts have some small dimensions to work with, so maybe a way of storing the parts inside the capo or on the capo would negate the need to fumble and the risk of losing the item.

Thank you for your feedback.

Wow yeah even still it seems like a hard sell.
I know it's just a project. But even with a clip on base, it would be hard to
Imagine an easy part swap.

I know, it's the biggest problem, but I just have to show I've done research and looked at it's problems and can evaluate what I would do again to make it better to pass this project.

So even though the feedback is negative, You're helping me a lot, a lot of people have said about the changing parts so I know that it's a design flaw, which means I can talk about this in my project.
#22
oh ok cool. so yeah, perhaps inclose a carry case.

or a headstock mount clip, for the capo and it's accessories.

i like the idea of your clip on pads but i think it will be expensive to produce. If you make it out of plastic you'll need to make a plastic ejection mold or if its going to be a metal pad you'll need to make a cast and that means making a wax mold and on and on... i would think of going with a dove tail system. That might make it a little easier to make and interchange. Just my two sense.

For this I don't actually have to make it, although I have to talk about the expected costs of production, and any problems that I may have in production. The dimensions of the changing parts make it troublesome regardless of production method which I am aware of.

Thank you for your feedback
