This thesis focuses on developing a centralized dishwashing service with the goal of reducing the amount of disposable tableware waste generated at Avinor Oslo Airport. Moreover, the project aims to help Avinor Oslo Airport achieve its objective of becoming a zero-waste airport by 2030.

The research process followed the Triple-diamond model, facilitating a structured approach through mainly three phases: Understand, Ideate, and Develop. The ‘Understand’ involves the study of the literature review, analysis of existing practices, field research, and stakeholder interviews to gain an understanding of the context. During the ‘Ideate’ phase three concepts were developed and evaluated through iterative testing and feedback. Finally, at the ‘Develop’ phase, the final concept, Green Circles, is developed. Green Circles is a centralised dishwashing service for reusable takeaway containers, that allows passengers to drop the containers at drop-off machines at the boarding gates and airport exists.

The implementation of Green Circles is expected to significantly reduce single-use tableware waste at Avinor Oslo Airport. The study highlights the importance of stakeholder engagement, convenient passenger experience, and efficient operational integration. Broader implications suggest that similar services could be adopted in other airports, contributing to the aviation industry’s sustainability efforts, such as those proposed by TULIPS.

The purpose of this project is to conduct an applied human factors engineering research on the operator interface unit to reimagine the human-machine interaction of EUV lithography machines.
The user research consists of interviews, observations, a survey, task analysis and incident report analysis. It highlights that the main OIU user groups are install engineers, field service engineers, upgrade engineers, and customer operators. The main differences between the user groups are that, from a machine perspective, the ASML users have infrequent, but long OIU-related use scenarios, and customer operators have more frequent, short OIU-related use scenarios. Additionally, the OIU use environment changes according to the type of user, the workspace around the OIU can be limiting, and the cleanroom can be a stressful environment to work in. Finally, results show that the majority of the users feel physical discomfort when using the OIU after a relatively short use duration.
The design analysis presents a selection of key results that each impact the selection of the following set of design criteria for the future human-machine interaction: Provide textual & pointing input, space for input tools, provide visual output, optimize work posture, use all around machine, mobile device workflow, keep pathways clear, quickly accessible, and ASML aesthetics.
The outcomes of the user research and the design analysis are developed into a design proposal by conducting research into technology advancements, adjacent industries, organizing brainstorm and co-creation sessions, and finally developing and choosing one concept to proceed with.
The proposal is a system applying AR headsets, customer control room advancements, and a new digital platform. It allows the OIU to be removed from the machine and allocates new employee tasks to enhance efficiency. AR headsets enable the engineer to access the machine directly, have real-time work procedures, hands-free gesture and voice control, and improved remote collaboration. The AR headsets and adapted user interface allow the user to access and execute software actions during hardware tasks in the cleanroom. Additionally, longer, software actions can effectively be performed from the control room. This new approach improves the employee work conditions, minimizes cleanroom presence, improves work efficiency, accuracy and safety.
The design proposal is a future vision and is expected to take about 10 years before fully developed. However, due to the urgent conclusions regarding current physical discomfort, it is recommended to pilot a short-term mobile workspace solution in addition to initiating the long-term vision development.

More and more (young) working adults in the Netherlands experience burnout-related stress symptoms. Although the focus of office environments is more focused on vitality, this trend keeps rising.

Products that already focus on awareness of well-being turn out to not be sustainable or even intrusive. Employees on the other hand seem to be burdened by occupational pressure while most people are like-minded when it comes to prioritising well-being over work.

Micro-breaks are necessary for keeping a steady energy level and most importantly required during stressful periods with high workloads.

The product solution is a simplified communication tool with only one purpose, communicating micro-breaks. The tools consist of a little display and are all connected. Every workplace or employee has such a product and by connecting it to your work computer or telephone, micro-breaks can be communicated with people in the same team. Different kinds of breaks can be communicated, depending on the team and facilities of the company. When team members are invited to participate in a micro-break they can simply accept, decline, or ignore the invitation.

The product aims to bring structure to taking breaks in a work environment and provides reminders during busy and stressful periods. In addition, the solution supports social interactions to lower the threshold for taking breaks. Ultimately to create a healthy working atmosphere in various environments.

The COVID-19 pandemic has highlighted the importance of indoor air quality in preventing the spread of airborne transmissive diseases. Offices are some of the largest hotspots for disease transmission. To address this issue, a joint venture between FLEX/design and Euromate, called ‘X-Lair,’ aims to design an air purifier specifically targeting the reduction of airborne disease transmission.

This project focuses on developing an air purifier solution that not only effectively reduces the spread of airborne diseases but also considers user experience and implementation in office environments. While primarily designed for placement above desks, the proposed solution has the potential to be applicable in various contexts.

Extensive literature research, user tests, empirical studies, interviews, and mind- mapping techniques have been employed to explore the research domain, identify design drivers, and establish a list of requirements. An iterative design approach, including tests with smoke and computational fluid dynamic analysis, have guided key design decisions. Additional tools such as Midjourney and virtual reality have facilitated the elaboration and visualization of ideas in their intended environment.

The final design proposal of the Personal Air Filter features a suspended configuration above desks, providing a large capture area to effectively filter the user’s breath. Plume propagation is considered by locating the air intake at the edge of the hood. An integrated lamp ensures comfortable ambient lighting, enhancing the device’s aesthetic appeal in office settings and improving employee well-being. A user interface, including a smartphone application, allows for convenient control of ventilation speed and lighting intensity. Smart features like the ‘smart mode’ enable autonomous operation, while interconnectivity between multiple devices enhances overall effectiveness and reduces noise.

A functional prototype was developed to validate the device’s efficacy and user experience. Smoke tests demonstrated the Personal Air Filter’s effective smoke capture at both 100 and 200 m3/h, indicating the potential for downsizing the device without compromising its performance. Special attention should be paid, however, to ensure that the Personal Air Filter operates at an acceptable noise level below 45 dB, taking into consideration the need for a quiet and comfortable office environment. Furthermore, user tests emphasized the need for a smartphone application and adjustable height for the Personal Air Filter.

In summary, the design of the Personal Air Filter represents a significant advancement in improving indoor air quality and promoting the well-being of office employees. The Personal Air Filter has the potential to become a unique and effective solution for mitigating the spread of airborne transmissive diseases.

The objective of this thesis is to enhance existing harness designs, with a focus on reducing discomfort and enhancing overall performance.
The contextual analysis, literature review, and desktop research yielded crucial insights and identified areas of improvement. Supplementary interviews were conducted with the user group. Initially, anthropometric data was sourced from existing databases like DINED; however, it lacked specificity to kitesurfing and the stances taken during kitesurfing, and some measurements relevant to the design of a kitesurf harness were missing, such as the torso length. To address this, an analysis of individual scans was done, followed by 3D scans of persons in kitesurfing stances.
It was found that the main factors leading to discomfort are the movement of the harness on the body, the pressure on the ribs, and the lack of pressure distribution. The main design goals stated are improved pressure distribution within the variation of movements and body types.
The findings of this thesis offer valuable insights into the potential for enhancing kitesurfing harnesses in terms of comfort, safety, and overall performance. By taking into account both the engineering and ergonomic aspects, this research contributes to the ongoing evolution of kitesurfing equipment, catering to the diverse needs and preferences of kitesurfers.
The final design is a modular kitesurf harness increasing the repairability, maintainability and upgradeability. The project includes anthropometric design guidelines for a kitesurf harness and multiple prototypes to test the concept. Resulting in a set of recommendations and designs that the Mystic team can take into consideration in the future steps towards developing the ultimate harness.

This graduation report describes the design of an ice cooled liquid circulation cooling vest for INUTEQ, a company specialized in personal cooling. The new design, the INUTEQ ICE, is made for warehouse and factory workers. They need cooling vests, because they work in large buildings with flat roofs. Large buildings cannot be cooled by air-conditioning anymore and the sun can heat them up to tropical temperatures. Additionally, the temperature may, in some cases, be increased by the production processes inside. Working in the heat can decrease productivity, performance, comfort and safety. The physical work these people perform also increases their chances of heat related illnesses such as: heat rash, heat cramps or heat exhaustion. In some cases, overheating can even lead to a heat stroke.
One of the solutions to cool people down is with cooling garments. The INUTEQ ICE is an improvement on traditional liquid circulation garments, which cool by running the water through silicone tubes. The new design makes use of open cell foam pads to increase the heat exchange between the cold water and the body. The developed cooling pad technology was found to have a nearly three times as high cooling capacity per unit area compared to liquid circulating cooling technology currently on the market. In the same experiment, the cooling capacity per unit area of the new pad technology was found to be similar to existing 6.5°C PCM packs and higher than 15°C and 21°C. The design has the potential to cool for longer than the 6.5°C PCM packs. Contrary to evaporation and air based cooling vest, the INUTEQ ICE is able to be used underneath enclosed clothing and in other high humid environments.
The project contained three phases, an analysis phase, a development phase and an evaluation phase. In the analysis phase, relevant information about cooling garments and the target group is gathered. This information is brought together in a list of requirements. In the development phase, the cooling pad technology is developed and the cooling method is defined. The development phase ends with the first concept of the INUTEQ ICE. In the evaluation phase, a working prototype was made and user tested in the appropriate context, which provided useful insights towards the final concept. The evaluation phase also contains the previously mentioned cooling capacity test and recommendations to continue the project.
The end result of the project is a promising final concept, with working prototype. The INUTEQ ICE has the potential to become a product that, in humid environments, performs better than alternative cooling garments. With further development it can be used by different target groups, not only factory and warehouse workers. It seems likely that a finished version of the INUTEQ ICE can add value to INUTEQ’s product range.

The subject of this thesis report is a new concept design recommendation for Zodiac Aerospace with respect to better hygiene and cleanliness in aircraft lavatories during long haul flights.An integrated design research approach is taken to solve the issue of poor hygienic behaviour in the lavatory. This includes an analysis of the current standards and practices surrounding aircraft lavatories, a review of existing products, an analysis of relevant stakeholders, observational research onboard active flights and finally a concept design which aims to improve passenger hygiene. Research indicates that the small form factor of the lavatory makes it challenging for passengers to behave in a hygienic manner. The new design emulates the cubicle based layout of public restrooms, where wash basins are shared. Each lavatory increases in size by removing their wash basins and situating them in the cabin, where they are shared by passengers. Provision of separate lavatories for men and women enables the use of urinals for men and additional space for women and passengers with reduced mobility. Aircraft lavatories can be kept clean on long haul flights by creating new lavatory services and layouts which expand the space within the lavatory. Airlines can improve passenger hygiene and therefore satisfaction by providing lavatories which are larger and cater to more specific needs, such as standing and sitting urination. The new design is also of benefit to the process of manufacture and maintenance as it simplifies the existing product significantly and reduces the time it takes to clean and disinfect the aircraft between flights.
