Overview (resum en anglès):
Public transportation is a vital component of urban mobility, contributing to reduced traffic congestion and environmental sustainability. However, the working conditions of bus drivers, who are essential to this system, often involve significant challenges, particularly due to the high levels of noise in the driver's cabin. Prolonged exposure to such noise can lead to increased stress, fatigue, and potential long-term health issues, which in turn affect the safety and efficiency of public transportation services. This thesis aims to address these noise-related challenges by utilizing the TRIZ (Theory of Inventive Problem Solving) methodology to develop innovative solutions that improve the working conditions of bus drivers.

The research begins with an analysis of current bus cabin amenities, identifying the headrest as a key area for potential improvement. Through spontaneous conversations with bus drivers operating on various routes in Barcelona and a review of relevant regulations and health considerations, the study highlights the critical need for effective noise reduction and enhanced ergonomics. The TRIZ methodology is then applied to explore inventive principles that can mitigate these issues without introducing new complications.

Two primary solutions emerge from this analysis. The first solution involves integrating an active noise cancellation system within foldable headrest spoilers. This system captures ambient noise through microphones and produces counteracting sound waves through speakers, effectively reducing unwanted noise. The foldable design allows drivers to adjust the device according to their height and desired level of noise filtration. The second solution is a removable peripheral noise-cancelling device that can be attached to the existing headrest. This device offers a cost-effective alternative, allowing drivers to opt for noise cancellation if needed without extensive modifications to the bus cabin.

Both solutions are designed to enhance driver comfort and concentration, thereby improving safety and operational efficiency. Additionally, these innovations are evaluated for their sustainability and ethical implications. The economic impact includes potential cost savings from reduced driver turnover and improved health outcomes. Socially, the solutions promote better working conditions and job satisfaction. Environmentally, the noise reduction technologies contribute to a quieter and more pleasant work environment.

Ethically, the implementation of these solutions respects driver privacy and autonomy, as the devices are designed to be user-controlled and adaptable to individual preferences.

In conclusion, this thesis demonstrates the practical application of the TRIZ methodology in addressing real-world problems within the public transportation sector. The proposed solutions not only tackle the immediate issue of noise in the driver's cabin but also promote long-term benefits for drivers, transit systems, and the community. By focusing on innovative, sustainable, and ethical approaches, this research emphasises the importance of continuous improvement in enhancing the quality of public service environments. These findings highlight the potential for widespread adoption of such solutions in various urban settings, contributing to improvement in the public transportation experience.
