Provide here an overview of the contents (structure) of this chapter. In a context where technological developments and professional responsibilities are constantly evolving, ethical and deontological issues have become essential in guiding decision-making and professional conduct. Beyond technical skills, professionals are expected to act in accordance with moral principles, legal frameworks, and the broader interests of society. These considerations contribute to building trust, ensuring accountability, and preventing harmful practices.

Ethics plays a central role in engineering design, ensuring that technological solutions contribute positively to society while avoiding harm. In a context where technological developments and professional responsibilities are constantly evolving, ethical and deontological issues have become essential in guiding decision-making and professional conduct. Beyond technical skills, engineers are expected to act in accordance with moral principles, legal frameworks, and the broader interests of society. This is especially important in healthcare environments, where user safety, well-being, and trust are critical. This chapter examines the ethical and deontological aspects of the multisensory cocoon concept, designed to improve patient experience through immersive projection technology. The analysis is based on engineering ethics principles and sustainable development frameworks. Key topics include engineering ethics, ethical considerations in sales and communication, environmental responsibility, and liability. Special attention is given to user well-being, sustainability, accessibility, and safety. Finally, this chapter also connects ethical considerations to the Life Cycle Assessment (LCA) and Design for Sustainability (D4S) approach used in the project

In many countries the Code of ethics of the engineering profession is contained into the official statutes, such as the Statutes of the Order of Engineers in the case of Portugal.

This code is intended to guide future engineers by including several deotological obligations such as:

• Duties to the profession
• Duties to the community
• Duties to the employer / client
• Duties to colleagues Engineering ethics is part of business and corporate ethics and focuses on the responsibilities of engineers toward society, the profession, and stakeholders. Engineers must ensure that their work contributes positively to people and the environment, while minimizing risks and harm. According to principles of sustainable engineering, engineers must aim to maximize positive impact and minimize negative impact on both people and the environment . This is especially relevant in healthcare-related projects, where user safety and well-being are critical. For this project, the following ethical duties are particularly relevant: - Duties to the profession: The team must ensure that the design is safe, reliable, and based on sound engineering principles. The system should not create additional risks for patients or healthcare staff. - Duties to the community: The solution aims to improve patient well-being by reducing stress and anxiety. This aligns with the ethical responsibility to contribute positively to society. - Duties to the employer/client: The design must be feasible, realistic, and aligned with healthcare needs and constraints. It should provide real value and not just a conceptual benefit. - Duties to colleagues: The project requires collaboration across disciplines (design, healthcare, technology). Ethical behavior includes clear communication, respect, and shared responsibility. ==== Sales and Marketing Ethics ==== In this project, it is important to avoid exaggerating the impact of the solution. While immersive environments can reduce stress, it is unethical to claim guaranteed medical outcomes without sufficient scientific evidence. Ethical marketing requires: - Honest communication about the benefits and limitations of the system - Avoiding misleading claims about medical effectiveness - Presenting the concept as a supportive tool, not a replacement for medical treatment This ensures trust between designers, healthcare professionals, and patients. ==== Environmental Ethics ==== Environmental ethics plays a key role in engineering decisions. Sustainable development requires balancing environmental, social, and economic aspects. For this project, the main environmental concerns are: - Energy consumption (projectors, sensors, HVAC systems) - Material use (aluminum structure, PVC, electronics) - End-of-life (electronic waste and recyclability) According to sustainable engineering principles: - Engineers should adopt a life-cycle approach (“cradle-to-grave”) - Designs should aim for durability, recyclability, and low environmental impact. This means the cocoon should: - Use recyclable materials where possible - Minimize energy consumption - Be designed for disassembly and recycling ==== Liability ==== Liability refers to the responsibility engineers have for the safety and performance of their product. In this project, key risks include: - Electrical safety (projector, sensors, wiring) - Fire hazards (electronics and enclosed space) - Physical safety (structure stability and accessibility) Engineers must: - Comply with relevant standards and regulations (e.g. CE, safety norms). - Ensure the product is safe under normal and foreseeable misuse. - Clearly define limitations of use. Failure to address these risks could result in harm to patients and legal consequences. ==== Summary ==== Provide here the conclusions of this chapter and make the bridge to the next chapter. Based on this ethical and deontological analysis, the team chose <specify here the design, technique(s) material(s), component(s)> for the following <specify here the relevant ethics-related reasons>.
  Consequently, the team decided to design a solution with the following <specify here the features added for ethical reasons>. This chapter highlighted the importance of ethical and deontological considerations in engineering design. The project must not only be technically feasible, but also socially responsible, environmentally sustainable, and safe for users. Based on this ethical and deontological analysis, the team chose to design a non-wearable immersive cocoon environment using projection technology, a strong aluminum structure, and integrated sensory components, because these choices: Improve patient comfort without requiring intrusive devices Reduce hygiene risks compared to wearable solutions Allow for a safer and more accessible user experience Consequently, the team decided to design a solution with the following ethically driven features: A non-invasive design (no wearables) to ensure comfort and hygiene Energy-efficient components to reduce environmental impact Safe and stable structure to protect users Accessible design for different patient groups (including reduced mobility) Honest positioning as a supportive tool, not a medical treatment This ethical approach ensures that the final design aligns with both professional responsibilities and the broader goals of sustainable and responsible engineering.
