I have applied for jobs at a few different companies. At one I was passed over twice before being hired. The previous 2 were 'great guys', but they didn't have the technical ability, and didn't learn the technical side. So the company finally had to hire a 'tech' to do the job. At another company I was asked to look at an applicant's resume. My conclusion was he didn't have any relevant education or experience for the job. H.R. ignored me and was anxious to hire him because 'you don't know how cheaply he will work'. In my opinion it is false economy to hire an unqualified applicant at low wages because the qualified applicant is too expensive. Many times I seem to be in the minority.
My dump trailer works great!! Has for over 10 years. No mods and it's a fairly large trailer too. I can put enough sand in it that my lawn tractor can't pull it. With this said, by increasing the height of the trailer is it not a safety hazard with the center of gravity higher from the ground. I bought my trailer for commercial mowing purposes and mowed some what I call dozer slopes with it. While I don't tow a trailer on these, I could see someone doing it and losing control of the tractor. I imagine an ATV trailer would be smaller due to greater chances of seeing rough terrain.
The assertion that the trailer did not lift high enough to dump the load shows that it ws made for a different type of load, such as marbes or golf balls. Really, many of the dump trailers are sold to toy buyers and just being able to tilt up is all that they really need. The challenge is indeed cost, since it often costs more to do a job right than to do it "sort of right" The higher tip angle would require more force or a longer cylinder, or a different arrangement and a higher-capacity pump, which costs more. So it is likely that designing for minimum build cost is what assured poor performance.
I wonder whether the designers of these things might have been concerned (there might sell be safety regulations or guidelines about center of gravity, etc.) with the possibility of the trailer tipping over sideways if it were raised too high?
Perhaps it is a design error. Dump trailors need to tilt at least 45-50 degrees.
There seems to be some element of incompetence in the design world today. Management hires the mechanical engineering graduate with the best grades and at a bargain price. But, can he change the tire on his car?
Companies would rather have an army of inexperienced engineers than a few competent engineers that know what they are doing. And the low productivity and chaos that comes with it...
I have 'non-kink' garden hose that kinks more than regular hose - did someone think to test this product at different water pressures and temperatures? I bought a special bottle designed to hold water and attach to my bike - its sole purpose - to hold liquid.
I find it very interesting that everyone on the design news site has jumped on the speculation that the dump trailer design was crippled by tight regulations. If I was going to speculate why a product went to market with less then perfect performance the first thing that I would think of is that is is cheaper to produce. I have seen a lot more incidents of designs being watered down to lower cost then any other reason.
Sometimes engineers can make some suggestions and review the regulations to improve them. It is certainly helpful to have regulations to improve safety but they should not impede functionality or deny innovations. All regulations should have specific rules regarding amendments and a review process. Effective regulations that promote safetya nd adherence to standards benefit everyone.
On the other hand, as some of the political discussions show, regulations can have a very debilitating influence on the industries being regulated to the point of strangulation.
A slew of announcements about new materials and design concepts for transportation have come out of several trade shows focusing on plastics, aircraft interiors, heavy trucks, and automotive engineering. A few more announcements have come independent of any trade shows, maybe just because it's spring.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
