Domestos Expand

  • Project - Bottle design for a new Unilever Domestos bleach formula, balancing mechanical, ergonomic and brand requirements

  • Product /service - New Domestos bleach formula that foamed and expanded to cover more of the toilet

  • Duration - 3 months

  • Team - Product designer, mechanical engineer, prototyper, project manager

  • Activities - Sketch ideation, concept illustration, 3D CAD design, prototyping, mechanical simulation, prototype testing, CMF and graphic design

  • Deliverables - Manufacture-ready 3D CAD files, blow-moulded prototype bottles, design recommendation report

  • Outcome - New design not yet progressed to manufacture

The project team ran a workshop to blueprint the product lifecycle for water bottles, for brands such as Dasani. We identified areas to improve environmental and social sustainability, and researched a range of technologies which might help, assessing them in terms of feasibility and cost

We explored in detail how to communicate the product USP - it's expanding foam bleach - through the form of the bottle and pack graphics, communicating this through Photoshop renderings. This is of particular importance in a supermarket setting where purchase decisions are made quickly and instinctively. We quickly gained a good understanding of the limits of the form language by collaborating with the client brand team. We explored different print options from shrink-wraps and labels to direct bottle printing

The team gradually focused their efforts on two main form concepts, and created quick 3D CAD models in Solidworks to ensure the ideas worked as expected in three dimensions

At this point, mechanical engineer and product designer worked closely together to define details that would allow for a robust, ergonomic bottle that returned to shape after being squeezed, yet still communicated the desired visual messages. This was done through sketches for speed

As the bottle concepts were iterated in 3D CAD, we considered appropriate dimensions by consulting ergonomic data on hand sizes and grip forces, considering plastic wall thickness and the likely 'squeezable' area we should provide. Balancing this with aesthetic considerations required co-designing between product designer and mechanical engineer

As we iterated our 3D CAD models, we conducted simulations in Solidworks to assess the expected performance - how easy they might be to use and how much force would be required to expel the correct amount of liquid. The designers used this data to inform decisions on small details such as bottle diameter, strengthening plastic ribs and base shape

Our client produced blow moulded prototype bottles using out 3D CAD data, and we carried out physical tests on these to validate our simulation data. The best performing concept was selected for possible manufacture and we handed over 3D CAD data and a design recommendation report to our client upon project completion
