TriMow- Grass Trimmer attachment for Mower

The man of the house stops to review his yard. For the last hour he has pushed 6.5 horse power of grass cutting machine over every inch of his yard. Now every blade of grass is standing perfectly at the right height. He takes a breath of relaxation, but it is cut short. Along the garden bed and the fence there is a 2 inch strip of grass that avoided the mower. He will have to get his trimmer out and walk the same yard he already walked. Slightly defeated he pushes his mower back the garage. If there was a way to mow and trim at the same time this man would be enjoying a cold Pepsi and a Twins game instead of being out in the sun for another 30 minutes.

The ETI TriMow (pronounced “trim-mow” not “tri-meow”) is here to restore weekends back to the American home owner. This attachment will trim grass on the left side of your mower. The Guide Wheel will automatically adjust the Spring Arm so that the TriMow Power Head will remain an effective yet safe distance from the fence. The on / off switch is manual with an cable up to the handle. The mower’s motor would run a small generator that produced 14 volts for the Power Head.

Design Challenges…

• Guide Wheel will not be able to handle uneven surfaces. (i.e. Picket Fences)
• TriMow Height may need to be adjusted a different points in the yard.

This is a $400,000 idea. It is held back because it is an accessory to another medium priced purchase. As trimmers start at about $75, this attachment might need to be in the $100 range. The product does not totally eliminate the need for a trimmer. There will be some spots in the yard not approachable by mowers. This is the design is also a long way away from complete so the business value is quite low.

 The TriMow is a great idea that needs doing. I need … I mean … Hypothetical home owner  guy needs every minute he can save on the weekends. And that ice cold cola is not going to drink itself.

PapeRoaster

The world is full of documents that that people no longer want. They also do not want other people to see them. That is why Adolf Ehinger made the first electric paper shredder in the 1959. His concept of the duel cutting cylinders attached to a motor has really been the standard over 50 years. Unfortunately this form of destruction cannot be trusted any more. As proven by such authoritative shows like CSI and Psych, these strips of paper can be reconstructed by people with nothing else to do.

It is also worth noting that there is now quite a large industry around document destruction. If a company shreds paper at their location then they have to dispose of the shredded paper that takes up twice the space that non-shredded paper does. There are companies like Shred-it that make millions by simply taking your paper away and disposing of it. The world is ready for a solution that really destroys documents and doesn’t generate dumpsters full of paper.

 

The world is ready for the ETI 3000 PapeRoaster. This takes the destruction process to an irreversible state. The paper is loaded into the PapeRoaster and is shredded into 1/8 inch strips. This process increases the surface area of the paper. Roller Cylinders feed the paper down the center. At this point two Heat Jet Manifolds will ignite propane. The strips of paper drop into the gauntlet of fire and are reduced to ashes. The final charred waste is collected in a high temp polymer bin.

The American Office now has a way of to achieve total document destruction.  Some of our cautious customers have expressed concern about an open flame and fuel source in the copy room.  The ETI 3000 PapeRoaster is fully incased in a 1 inch thick cement enclose. The Rollere Cyclinders inside restrict the flame and heat from moving up the shredder.  As an added precaution the bin door will not open if the temperature inside is over 110° F. These safeguards insure complete incineration without a chance of harming the operator.

Design challenges include.

• There is a good chance for the process to have air flow issues. Too much air and the ash will blow everywhere. Not enough and the fire does not burn.
• A vent might be added to allow heat to exhaust outside.

This is a $500,000 idea. Every major office in the world would want one. The units would sell for $3000 and could be built for $500. Shipping will eat into the profits as the Cement casing would weigh it down. Ongoing sales of the fuel could help offset some costs.

With the ETI 3000 PapeRoaster  bad guys everywhere would not fear the CSI search warrant. Lets see Gil Grissom reconstruct that on an oversized light table.

Until next time - Keep Thinking
