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.

Project goal: To rescale an existing self-winding watch design by enlarging it 5-6 times its current size using 3D CAD. Scope of work: - Analyze the existing design of the self-winding watch movement. - Scale the design from 30mm to 5-6 times its size. - Ensure accurate scaling of all 120 pieces and 80 different parts.

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"
