Product Design Engineering School of Design

Beth Fairgrieve (She/her)

My practice incorporates the combination of user-centred design with creating the best technical solutions: from early concept ideation, 3D printed prototypes, user testing to detailed engineering solutions.


I am passionate about helping all user groups through innovative design solutions and have learned the value of co-design, particularly while working with sensitive user groups. During my MEng project, I have worked closely with Alzheimer Scotland to design a light therapy device for people living with dementia experiencing sundowning; a type of agitation which is caused by disruptions to the circadian rhythm. The project began by exploring all current treatment solutions for sundowning, finding that many options have not been designed specifically for people living with dementia. As a product design engineer, it was my role to explore how new technology, combined with the best aspects of current solutions could be combined to create a device which improves symptoms. Interacting with carers and people living with dementia throughout the design process has allowed me to deliver the best possible product intervention considering user comfort with technology, aesthetics and dementia complex sensory needs.


I am passionate about listening to the user, taking time to understand the problem in depth and working alongside them to design the best solution which can improve lives.

Light Therapy for Dementia: ebb and glow

Light Therapy for Dementia: ebb and glow

By 2030, there are expected to be 1 million people living with dementia (PLWD) in the UK. Many – up to 66% – can experience Sundowning; a type of agitation which typically begins late in the day, causing a repetitive cycle of sleepless nights for PLWD and caregivers.


My product targets disruptions to the circadian rhythm, which is the cause of sundowning as dementia progresses. Daily blue light therapy is used to help regulate the circadian rhythm, tailored to the complex sensory needs of PLWD.


Introduced early into dementia diagnosis, ebb&glow aims to support caregivers with growing functionality as PLWD’s needs change throughout their dementia journey. The hand-held pebble shape is tactile and the single button allows users, from early diagnosis to advanced stages of dementia, to interact with smart home devices independently. This interaction is fully customisable and includes music, sound, light and helpful reminders.
