Mike Beck Posted August 22, 2008 Report Share Posted August 22, 2008 sup guy and gals........right, I'm in a slight dilemma, I'm re-starting my A2 coursework because the idea i had was, well sh!t lol. So i want to do something to do with trials or bikes in general but really can't think of anything at all, never mind for trials........i don't need any full in detail projects but just some starting ideas i can build on !!!cheers in advance for the help aha lewis Quote Link to comment Share on other sites More sharing options...

You have to have an idea for a product that has not been made yet, and then move from there. Quote Link to comment Share on other sites More sharing options...
psycholist Posted August 22, 2008 Report Share Posted August 22, 2008 What is the 'A2'? If you're looking for an engineering type project I have a few ideas (Given that I supervise final year mechanical engineering students and tend to give them bike related projects, there might be something of interest for you). Here are a few past and current:Design and build a test rig for brake power testing to EN14764:2005.Brake testing to EN14764.Design, build and calibrate a spoke tension meter.Finite element modeling of a bicycle wheel.Precession and its alleviation in threaded joints.Design of an alternative to a derailleur based bicycle gear system.Design of a hydraulic gear shifter, preferably open system and self indexing.Measurement of pull out forces/clamping force repeatability in front quick release skewers.Optical electronic measurement of wheel trueness.

Mike Beck Posted August 22, 2008 Author Report Share Posted August 22, 2008 yeah, my teacher basically said that i can't do anything with bikes because 'the market is too competitive' but i think if i base it around trials then i might me ok. With it being more of a specialised segment than say cross-country.A2 is second year A-level lol, basically i need to find a product that doesn't fullfill its purpose fully or finding a gap in a product market and basically improving stuff, so i think only a few of those you suggested are relevant lolbut cheers to both of you, was expecting a load of c0ckends saying, mate js make a nu bike init blud!aha lewis Quote Link to comment Share on other sites More sharing options...
psycholist Posted August 22, 2008 Report Share Posted August 22, 2008 Design of an easier, quicker way of mounting Magura pistons (Or a QR system for 4 bolt mounts to get the wheel off easily), especially with a booster would be an interesting one, as would a well designed, easily adjusted/self adjusting, impact tolerant chain tensioner. In terms of geometry, trials bikes are all pretty similar (For a given riding style) anyway because that geometry works well, so I wouldn't say there's a lot to innovate on there. A means of keeping tubeless tyres seated at low pressures on wide rims so they can be used for trials would be pretty cool (Though given my XC bikes runs tubeless and it's not noticeably better for grip or rolling than tubed and that I managed to pinch flat a tubeless tyre (Supposed to be impossible, but it clearly isn't), justifying the market may be difficult).

tris Posted August 22, 2008 Report Share Posted August 22, 2008 (edited) I did A2 DT last year and ballsed up as well....got a D.ANyways, just found this other thread and looks like quite a good idea.....Trials Proof HeadphonesSomething based on this could be a good idea because you can come up with a lot of ideas and it is a gap in the market.....Thought i'd add:They would need a system that holds them to the ears really well.They'd have to be shockproof.They'd have to be strong.Some sort of volume switch on the handlebars.Possibly a safety sytem so if the rider falls off or is near traffic the volume decreases.

Mike Beck Posted August 22, 2008 Author Report Share Posted August 22, 2008 haha, yeah i ballsed my AS up, probably because i did a set of compasses for drawing circles lol......yeah, the tensioners a good one, i always used to demolish mine when i had a stock, the only problem i can see with the quick release maggy mounts is that it might not hold as well, like for the power aspect it might fail and maybe worse off.....aha lewis Quote Link to comment Share on other sites More sharing options...

Mark W Posted August 22, 2008 Report Share Posted August 22, 2008 If the workbook 'n' initial ideas 'n' the like are all good, then they'll usually let it slide a bit if you f**k up the major project. It's essentially what I did, and I managed to blag an A, somehow.But yeah, why not move back a bit and look at bikes in general again, but at something like a maintenance stand? I know it's pretty boring, but it's pretty straight-forward to make, but you get to demonstrate a lot of different techniques for building it, you can also talk about how it would be used by shops or if it was cheap enough by amateurs in their own home, meaning that you'd be able to sell them and show your ideas for a business plan and stuff like that. Plus, if you do a decent job, it'd be useful for you afterwards anyway. It'd involve looking at how to make a strong, sturdy base, then the arm for it, then the bit that's going to hold the bike, however you choose to do that, then shelving for it, and so on - so that's quite a lot of different things already. Factor in that you'll be using a mix of metal and plastic/rubber and you're hitting a lot of the key marking criteria for an A2 piece.

Mike Beck Posted August 22, 2008 Author Report Share Posted August 22, 2008 yeah i was looking at that sort of thing originally, but i didn't think i would be able to do it because theres already loads out there. But i reckon i'll give it a go!! plus i'll be able to do some welding and jig making for the adjustment method so yeah i think ill stick with that!!tarr lads, great help aha lewis Quote Link to comment Share on other sites More sharing options...
Mike Beck Posted August 22, 2008 Author Report Share Posted August 22, 2008 ooo, before i forget.......i actually have to make it decently this year because the inspector people are coming to my school to make sure things are being done right!!!mint aha lewis Quote Link to comment Share on other sites More sharing options...
