#44 Earbuds with concept buttons by franznoise
There are unlimited ways to design bottons on the earbuds, but more hypothesis need more time. And an effective design needs the pcb dimensions and typology inside the earbuds. I hope you like my design and understand that this is just a preliminary concept that need to be developed.
thank you, best regards

#9 Pebble by Duncan SmartEng
A large, almost seamless pebble. The aluminium sheet exterior will look and feel like a stone (see below). It will certainly feel like a premium product.
Inside are 2 similar stones, one with fossil button and volume control.
This design should allow for ample component room, while appearing deliberate for aesthetics.
By bead blasting sheet aluminium, anodising it with the pebble colours, then cold pressing it into shape, it will:
- Feel like a pebble (cold to the touch, slightly rough finish)
- Look just like a pebble (any rock or stone pattern can be created with this technique)
- Each one would be unique
- Actually relatively cheap

Large 3D bookshelf backstop
Inspired by the historical visual progression of mainboards, we are looking for an innovative design to use as the back of a large shelving unit. We are looking for a design to go in a display case. The display case will then be used as a holder for glass shelves. Think of it almost like a glass bookshelf. Except, instead of the back being a cheap piece of board held on with tack nails like a shelf from IKEA, the back will be the design you come up with. Dimensions: 8ft wide 3ft high 1-3in deep The case is being used to display tech items. So we would like the design to reflect technology. Think mother board but on our scale. The original thought was to collect old motherboards, including ram and cpus. We were then going to lay them out on a 8x3 piece of plywood and glue them. Instead of this, we now want to get a design that a CNC machine can make. Material used: Wood and old metal. The design should induce a feeling of technological progression. So from left to right the design should transition from old circuit board tech, to current tech, to possible future tech (this part is open for interpretation) As an example, in the attached picture, the green part is what we want to replace with our 3D circuit board idea. Please note that the picture is just one from google and does not represent the actual shelf we are building The entire shelf will sit on top of a table, meaning that it will be at eye level for the average person.

I will also provide the original upright design so that you can use it as a reference when creating the new design I will need the job done by the 15th of october
Low Cost dental Chair Softgoods Design
The task at hand is to find an economic low cost method to manufacture and upholster adult dental chair soft goods. Quality and life of covering must be robust, 10+ year life. The dental chair soft goods typically consist of three major components; underlying support structure, many times this is a vacuum formed plastic element, the seat foam, and the upholstery itself (see attached photos). Dental chairs are normally divided into two main components; 1) The back structure, 2) The seating structure. Key to this design initiative, should include an alternate way of securing the leather to the underside of the chair. Most chairs currently utilize hundreds of staples to secure the fabric, this poses to problems: 1) High direct labor, 2) No way to easily replace the upholstery covering. We are seeking a new innovative design ideas for new methods of manufacture without using staples or typical snap fittings.
