Toothbrush pops open for recycling in Seymourpowell’s Un-Made concept
British design studio Seymourpowell has put cheap electronic goods under the spotlight with Un-Made, a project imagining four possible ways to design for quick disassembly and recycling.
As part of the project, Seymourpowell devised four automated disassembly mechanism concepts using an electric toothbrush as an example for their animated graphics.
Each of the mechanisms could be built into a product during manufacturing and then activated in a factory at the end of the item’s life.
The first Un-Made concept is a pin mechanism. Similar to the action of opening a SIM card slot on a smartphone, it involves poking a pin into a small, sealed pinhole on the rear of the product to release the internal components.
The second concept is a vacuum mechanism. It involves placing the product into a vacuum, causing closed cell foams and air-sealed features within it to expand and bust the external housing open.
Third, there is a piston mechanism that works by pushing a piston through a cap on the bottom of a device and forcing all of the internal components upwards until they emerge through the top.
The final concept involves using UV glue – a type of adhesive that deactivates under ultraviolet light. In this concept, the product is placed into a specially lit chamber to release the clamshell construction.
The Un-Made project was led by Eddie Hamilton, a senior industrial designer at Seymourpowell, who was driven to make the work after researching what electric toothbrush to buy for himself.
“Inevitably I went for the cheap one, at which point Amazon smugly pointed out they’d sold 10k+ of that model last month alone,” said Hamilton.
“As an industrial designer, I spend time obsessing over the product I’m working on, typically thinking of it in isolation,” he added.
“But one thing I occasionally fail to remember or adequately picture is the true scale of that product once manufactured. 10,000 units sold per month seems vast.”
Using Amazon’s bestsellers list, Hamilton ascertained that fabric shavers, steam irons, wireless doorbells, wireless computer mice, digital tyre inflators and USB-C adaptors were all items selling in their thousands each month, at a price of less than £20.
While designing products so they can be repaired is important, the associated expense may not be something that customers can justify for small items sold at this price point, Hamilton said.
“Even if we change societal attitudes, the bottom line is whether you should open that cheap toothbrush to replace a failing battery when you only paid £24.99 for it two years ago,” he said.
“I’m optimistic for some product categories to get the ball rolling, namely expensive and bulky items. But I’m also a realist that we need alternative strategies adjacent to repair. This is where we must design for disassembly.”
In Hamilton’s view, disassembly and recycling is a worthy “next best option” to repair for cheaper objects, as it keeps the materials in a circular material flow.
The Un-Made design team took inspiration from Agency of Design’s Design Out Waste project, which looked at three strategies for keeping a toaster out of landfill. But they particularly wanted to explore just how efficient the disassembly process could be made through automation.
The cheaper and easier the process, they say, the more motivation there is for companies to pursue this approach and recover the components and materials inside their devices.
“A huge part of the reason e-waste ends up in landfill is because of product complexity and the inherent challenges involved in their disassembly,” Seymourpowell lead designer Alex Pearce told Dezeen.
“To date, because e-waste has been considered too time-consuming and costly to disassemble – there has been no (commercial) incentive strong enough to make it a viable option.”
The materials inside even cheap devices are valuable, Pearce points out, particularly when there are supply shortages or when it comes to rare-earth minerals.
“When you consider that more gold exists within a ton of e-waste than within a ton of gold ore dug from the ground, a straightforward economic imperative becomes clear for companies who are able to recover and reuse these materials,” said Pearce.
Seymourpowell imagines disassembly taking place either at the manufacturer’s facilities following a take-back procedure, or potentially at a public recycling centre if disassembly processes have been sufficiently standardised.
The London-based studio is known for its innovative product and transport designs, as well as concepts that challenge current norms. Recent projects from the studio have included the two-in-one reusable Bottlecup and a spaceship cabin for Virgin Galactic.
New York is a city known for housing scarcity, and a place that’s defined by reinvention. For Timber House, MESH Architectures was inspired by natural finishes and “botanical architecture.” The idea was not only to foster well-being, but create a new model for timber construction in the city. The project is the first mass-timber condominium in New York, and the structure was built with glue-laminated timber columns, beams, and floor plates. The six-story, multifamily project is comprised of fourteen homes.
MVRDV has earned a reputation for reinvention and creating new building forms. That same approach extends to housing, where the team designed Valley with a more “green and human” touch. Built for developer Edge, the project is located in Amsterdam Zuidas. Rising to three distinct towers, the façades shift across the complex. The outer edges are mirrored glass, while the inner façades are clad with stone and swaths of greenery.
Few locations are more prominent for multifamily housing in St. Louis than Forest Park. Designed by Studio Gang, One Hundred is a residential tower overlooking the park and the studio’s first project in the city. The tower includes a mix of housing, retail and amenities on four-story stacked tiers. The apartments were designed for views of Forest Park and east to the Gateway Arch.
The Cirqua project by BKK gained widespread recognition for creating beautiful, inventive multifamily architecture. The project includes 38 unique unit types out of the 42 total apartments made with spacious balconies and an integrated approach to landscaping. Combining two properties into a single block, the project was formed with careful attention paid to scale and the surrounding context. Cirqua not only showcases a smart, nuanced approach to multifamily housing, but also how to design for accessibility and passive performance.
Caterpillar approaches density through a novel construction and design in Core City, Detroit. It utilizes a Quonset Hut structure that holds eight units, all entirely prefabricated. The result is an 8,000 square foot (745 square meter) residential project that prioritizes indoor and outdoor space. Prince Concepts created the project with tall ceilings that rise to 23 feet (7 meters); the units were designed to capture morning light in the bedrooms and evening sunsets in the living room.
CPDA Architects designed this garden house project as a multifamily development in Mexico City. Located in the Escandón neighborhood, the project includes fourteen residential units. At its heart, a central courtyard is the connective element that defines the housing project, opening up access to natural light and cross ventilation. Ten townhouse units are set up the four ground-floor units below, all of which share a similar material relationship.
Few cities in the world are grappling with homelessness and a severe lack of housing affordability like Los Angeles. Brooks+Scarpa has built a practice addressing issues in the city and across the nation. For this multifamily residential, The SIX was designed as a 52-unit affordable housing project that “provides a home, support services and rehabilitation for previously homeless and/or disabled veterans.”
Over the last two decades, development in China has been defined by a dizzying pace and new architecture produce in-mass. For Jinshan 9, this force behind new buildings was directed into a multifamily living community. Located in China’s Shekou mixed-use district, the project looks out west to wild, forested mountains and east to Shenzhen Bay Bridge. With a range of both low-rise and high-rise structures, the development was made for diverse lifestyles and populations.
