Carl Johan Jacobsen – Hardwear

by Carl Johan Jacobsen

In the U.K new court ruling threatens trans-people while the US government is doing a full assault on trans and female bodies. Hardwear is a collection of wearable objects offering a sense of protection in urban environments, as a response to a growing tendency of hostility towards the body. Hard surfaces become flexible armor, protective shields transform into high heels. Whether to preserve personal space on public transport or to create cognitive distance Hardwear aims to create a sense of security. By using hard materials, the feeling of being safe inside a car is transformed to the outside resulting in a line of wearable objects made for for everyday resistance. Drawn on protection typologies from sportswear, Hardwear is made of 100% recycled plastic with 3D printed elements.

Stool Story

with Christophe Guberan

‘Stool Story’ invited students to explore innovative, re-contextualised, or intriguing materials and production techniques to create a simple yet fundamentally structural typology: the stool. Each process was documented through a short, vertically formatted video. The result is a range of stools, each demonstrating a unique perspective and approach.

SolarPunk

with Philippe Malouin

SolarPunk is a design exploration into how increasingly accessible solar energy might shape and integrate into our everyday lives in the near future. Embracing a hopeful vision of sustainability, the movement challenges traditional perceptions of renewable energy by imagining creative, aesthetic, and functional uses of solar power. This collection of work was created by first-year Master’s students in Product Design at ECAL, under the guidance of designer Philippe Malouin. Developed specifically for the Soleil·s exhibition at the MUDAC design museum in Lausanne, the projects reflect bold experimentation and speculative thinking. Rather than focusing solely on efficiency or utility, the students explored poetic, playful, and sometimes unconventional applications of solar energy, highlighting the emotional and experiential potential of this technology. Among the featured works are two standout projects which have been developed and feature in the exhibition: ‘Solar Shade' by Carl Johan Jacobsen, a wearable hat that powers a cooling vest using flexible solar panels, and ‘Butterfly Sunglasses’ by Takumi Ise, simple lightweight eyewear that combines colour, movement, and solar functionality.

Designed in CH Made in JP

with Augustin Scott de Martinville

Designed in CH, Made in JP is a collaborative project between ECAL Master Product Design, Karimoku New Standard, and Presence Switzerland. From 13 April to 13 October 2025, representatives from countries across the globe will gather to showcase innovation, culture, and sustainability at the World Expo in Osaka, Japan. For Switzerland’s pavilion, MA Product Design students at ECAL were tasked with designing a stackable wooden chair to be produced in Japan by Karimoku New Standard, intended to furnish the lightweight, bubble-inspired architecture by Manuel Herz. Under the guidance of Augustin Scott de Martinville, the class developed ten chair designs, each offering a distinct perspective. Some draw inspiration from the pavilion’s scenography, while others explore cultural iconography or celebrate the symbiosis between two nations—each unique in heritage yet united by shared values of craftsmanship and innovation. Of the ten designs, one was selected to be produced for the pavilion: HUG, designed by Jacob Kouthoofd Martensson and Min Xiyao, is a circular chair that stacks inversely—a feature that not only informs its name but also visually embodies the essence of collaboration. This versatile design accommodates a range of uses, from conferences to general pavilion seating. The final chair will be unveiled both in Osaka in the Swiss Pavilion at the World Expo 2025, and during Milan Design Week 2025, with the full project exhibited at the House of Switzerland.

Heat Pumps for Viessmann

with Augustin Scott de Martinville

Heat pumps are energy-efficient household climate systems essential for transitioning to renewable energy and combating climate change. Typically installed outside close-by to buildings, they are becoming common visual elements in urban landscapes, often resembling air conditioners with limited design variety across brands. To reimagine these essential typologies, Viessmann, a world leading Heat Pump producer, invited MA Product Design students from ECAL to develop innovative concepts, resulting in designs that challenge norms and explore new visual identities of heat pumps.

Transformations

with Studio Isabel + Helen

This workshop was led by Isabel + Helen Studio, a duo of London artists known for their captivating kinetic sculptures and installations. They blend art with movement to create playful and thought-provoking works. During the week, they guided students through the fundamentals of creating dynamic, moving sculptures. Using umbrella mechanisms, students created fireworks.

I as an Island

with Chris Kabel

Like Robinson Crusoe scavenged the wrecked ship for materials to build his home, First Year Master Product Design students, guided by Chris Kabel, were invited to delve into the flotsam of their creative minds for this open workshop. The workshop began with collecting, organizing, and analyzing creative flotsam and jetsam to create a self-portrait as a designer. Unrealized projects, obsessions and fascinations, irritations, vague dreams, (bad) jokes, and ideas too weird to talk about—all these resided within a designer's mind. Beginnings already existed: inspiring photos on phones, inviting materials, first ideas hastily scribbled down, quick sketches on paper, half-baked assemblages, or flimsy maquettes. These fragments and particles were analyzed to discover the kind of designer each participant was, extracting a direction for development during the week. This process of analysis, ideation, and translation, including the ‘end result,’ became visible as an island, shaped and populated by each individual's design process. It featured fragile beginnings, iterations, and the choices made along the way, culminating in a final conclusion shaped by material samples, shape research, 3D sketches, the development of a mechanism, a campaign, a film scenario, or whatever else was distilled from the initial flotsam.
