University Research

Recommended Posts

Hey guys, I'm doing research for a university project and was wondering if any of you would be happy to fill out a quick survey for me. It's 6 questions so should only take a couple of minutes and any responses would be great! The survey is anonymous so there's no need for personal details.

Thanks!

Not sure such a product would be of much interest as it would depend on the caravan having it’s own battery which would be discharged during the journey.  What happens if the battery is flat.

 

Ref warning you of a failure most modern cars already have a bulb failure device which will operate when the canal is coupled up through a 7 or 13 pin connection.

 

for the few seconds it takes to connect up with the existing system it probably isn’t worth it.

The question "If this product could tell you on your journey when a light has failed, would that be helpful to you?" needs another alternative answer, eg "does your car automatically report trailer bulb failures?" as yes/no to the question as posed is inadequate for many outfits.

Don’t see the point of connecting the lights wirelessly if that left the ATS still needing connecting,  And if the ATS was connected wirelessly I would worry about the security of the system.  
 

There would be concern re. Battery drain and fridge power.

I have looked at the questions and find them totally worthless.

I do not know of any car that does not have bulb failure warning as that is a requirement in cars today.

Secondly, with the adoption of the 13 pin system it would be a duplicate system and not worth the cost to install.

 

I am afraid the OP has a failure before he starts.

For goodness sake, it's an educational research project, not a Hella marketing survey!😁

The wording does suggest a product has already been devised and the survey is market research to judge demand.

Considering the existing connector not only transmits power to the caravan exterior lighting system but to other electrical equipment in use while the caravan is in motion, such as charging the battery or running the fridge, I see no benefit in such a device as it would still need a separate connector for non-lighting usage. If anything, a device that would automatically electrically couple all 13 pins between the towing vehicle and the trailer during the actual hitching process might be worth looking at.

It may be so, but it is flawed from the start.

 

Why would one want to pay extra to install a product that duplicates what is already present, and has a proven track record.

 

I see no benefit in the product , just something else to go wrong, or its power supply compromising other items.

I don't think there is such a suggestion but even so that is irrelevant as it is clearly described as a university project. Surely we should be encouraging academic study and not going straight into negative criticism and judgement.

No one is asking you to pay for and install anything you don't want. It is simply an academic research survey from which students will learn. The survey doesn't ask what benefit you think it might be. Whether it is flawed or not isn't our call. People learn from mistakes, not overly critical and unwarranted judgement. No one is being forced to take part so if you see no point in it ignore and move onto the next thread.

I agree, and I would be one of the first to applaud a realistic study, but this one is not one of those.

It is superfluous , and a cost that is simply trying to fix something that is not broken.

 

If a researcher gets negative criticism and negative judgement that alone should send up red flags and make him or her realise they are on the wrong course.

What is the background to this study that allows you to decry it as unrealistic and superfluous?

 

The project is not trying to "fix" anything. It seems to me that someone (possibly the son or grandson of a caravanner) is working on an unusual or different way to develop and use wireless technology.....just because he can. It is not our place to criticise or judge and subsequently dissuade and dishearten. Our role in this is to take part or decline to take part. The course tutors will do the assessing and judging.

I don't think the OP has done enough research into what is actually connected when a caravan is plugged into the car.  He/she does not seem to realise that there is more than the road lighting connected.  

 

The proposed system may work for an 9lder car towing a trailer but not for a modern car & caravan combination.

 

As an ex technology teacher this is the sort of project I might have let a yr9 or 10 pupil attempt but at higher levels and certainly university level much more rigor is needed.

My rear view camera connects itself wirelessly - why not the lights as well?

And yes, I'd like a device to confirm the caravan lights were working - one job less for OH before we set off.

Why not go the whole hog and integrate hitch, jockey wheel, stabiliser, electrical connector and motor mover to enable one touch hitching?

Have you ever had problems with the electrical connector on your caravan?

 

Would a wireless alternative be of interest to you so you don't have to connect the cables before travel?

 

I wonder how power to charge the battery and fridge whilst travelling can be accomplished without any connectors or am I missing something.

 

My tug does not have any warning of light failure, so that would be handy for me.

I think you're failing to see the big picture here.

 

Integrate the tug and living compartment into a single coherent structure.

 

(What should we call it???  Let's think of something which links a motor with a homelike environment...)

 

Motor...home?

 

Nah!

Perhaps it’s a wireless 12v connection? think outside the box, if all we had to do was hitch that sounds good to me. All the LED canbus issues sorted .....yes please.

 

Also, I have assisted countless people on sites struggling with their 13pin connections due to mainly alignment issues from connections to unplugging.

 

Form completed David good luck 😉

Like this perhaps? I shared this on Swift Talk last year 😊 the comments are a tad predictable of course.

Well done davidh, you asked some good questions.

The question 'How much would you be willing to pay for such a product?' needs another line.

Would not buy.

 

The question assumes that everyone taking the survey would want to buy the product and would give false results.

I can see the only issue would be the charging of batteries / battery and possibly arriving at a site and no battery left for the mover but the light powered by the caravan would benefit some that use their motor mover on the road to park at home .

 

Fridge could simply run on gas if needed while being towed with quick mod .

Albeit 50 years since I read the C&U and lighting regs when I was tasked with finding out if a very specialist trailer the company I worked for at the time built for the Navy was legal on the roads.

 

But I seem to remember that trailer lights had to be powered from the towing vehicle.

thanks for all your responses guys! the product is not something that has been made as of yet. it is market research for a 'potential' product for a business management module. It doesn't matter to us if the product would be a success or failure we just have to get as much information as possible for a pitch and say whether or not the product would be a viable investment or not.

yes this is true, it is a group project and i'm looking into one specific part of it. Other people are doing further research into that sort of thing and we will compile later on

from research from other group members i believe this law has changed in recent years

In that case I hope the survey and the comments, including negative ones, will be of use to your project.

Because you need power to operate them.

Not quite sure where youre heading with this but:-

 

Negative

1) Caravans generally have two high(ish) current connections - Battery Charging and Fridge supply

2) They can also have stability devices such as ATC that has a current draw circa 10 amps or so

3) The lighting needs a supply and we dont really want to flatten the onboard battery which will be used on site to provide power and to pitch up using a motor mover.

4) The potential for a wifi link to fail is in my mind too great and an unnecessary complication.

 

Positive

1) Getting rid of the physical connector would be good

2) One less item to forget

3) No cables to drag along the floor

4) No crawling around on hands and knees to connect the van up

 

Alternative

1) A two pole heavy duty connector and canbus signals sent down the wire
