20 feet Shipping container needed to used for a mobile Solar power station a total of 36 panels needed to be mounted in top and side of the container. The unfolding of these panels at site should be motorized by hydroluyic system. The Tilting angels should be adjustable. The set up of the system should not exceed half an hour.

This is for a new mop invention. I was able to make a somewhat functioning scaled model of just the internal mechanisms as seen in the attached video. Taking from the carpet sweeper seen here: http://bit.ly/32vqkGF, I want it to have 3 sponge rollers that spin in alternate directions at an accelerated speed (3:1) so that when it is pushed across the floor, the sponge rollers spin to mop up a mess. I used gear pullies to spin the rollers, however, I am open to any kind of gears based on your expertise for efficiency, durability, efficacy, and cost of goods. This will be a retail product and I would like to keep the price competitive with sweepers. Please provide the following: - Completed product with retail-ready design - Full size (similar to the carpet sweeper) - Rollers should have push pin or equivalent to easily pop rollers in and out (they will be replenishments with a variety of roller options (i.e. brillow, sponge, brush, shammy, etc.) - It should break down to fit into a retail box, again similar to the carpet sweeper link provided. - Rollers are 1" diameter - Wheels are 2"

We want to design an arm which can be mounted on a tripod as shown in the attached image. The total length of the arm is going to be 1.5m from pivot to end effector. For the movement of the joints please refer the other image. The total weight of the arm and the mechanism has to be less than 3kg. The payload is going to be less than 300 grams. Your job is to design the underlying mechanism which can drive this arm as smoothly as possible. The deliverables are going to be CAD of the mechanism and BOM and anything else which will be required to prototype the arm. The project will only begin with this contest and the designer will be hired for continuation of the project.

Looking for an engineer who can design a wall grappling hook that can suspend a hanging chair hammock between two partition walls in a toilet stall. The chair hammock has 4 straps which are attached to 4 identical wall hooks affixed at the top of the toilet stall partition. The hook must be able to hold securely in place as load weight is gradually applied. The typical user will install the hammock as follows: attach hooks on the side partition walls of the toilet stall - towards the front and back of stall and on both sides, attach hammock straps onto the hook, sits down on the hammock and if necessary get back up to adjust straps to ideal chair height and position. Previous designs of the hook did not stay in place and slid towards the centre of the wall due to side torque as weight was applied via the straps at roughly 45 degree angles (which also damaged or marked up the walls). We need a rockstar engineer who can solve this design challenge with a sense of humour.

你好Cadcrowd我目前在专利申请中twisted wire brush and the use case is to clean hookahs. To give you a little bit about my background I have owned and managed my hookah lounge for 12+ years and recently have come up with a new improved design for the standard hookah cleaning brush, I have attached pictures of 3 brushes the brush on the left and middle is what is currently in production, and the left is my design. I would like to emphasize that materials are all the same, steel for the wire and nylon for bristles for cleaning hookahs. My design is collaborating the standard stem wire brush cleaner on one opposite end and my twisted hollow design on the other, making sure two exposed areas of wire for hand placement. I currently have been using a working prototype I made which is one of the pictures included showing my design inside the hookah, take note how longer bristles face in one direction. I need professional blueprints of my design to present to a manufacturer The overall dimensions are included in sketches brush should be roughly 60cm, bendable in the hollow area to allow longer bristles to elongate. Also longer bristles facing one direction should be (7 cm)
