Research On Phototherapy Product Design For Seasonal Affective Disorder

Seasonal affective disorder is a kind of depression that occurs periodically in specific seasons.Patients usually get sick in autumn and winter every year and return to normal in spring and summer the next year.At present,phototherapy is the main treatment.The scientific research of phototherapy is becoming more and more perfect.However,there are still many problems in phototherapy products,and there is little research in the field of phototherapy product design.Therefore,this paper aims to explore the design strategy of phototherapy products,and design a phototherapy product that can effectively treat seasonal affective disorder and meet the needs of users.Firstly,this paper expound the contents related to seasonal affective disorder and arrange the scientific research achievements related to phototherapy;Then,compare and analyze the existing phototherapy products from the aspects of technical parameters,function,structure and ergonomics,summarize the key points of design and explore the pain points of the products;Then,the user survey is carried out by the combination of survey and interview: on the one hand,collect user evaluations of phototherapy products based on network data,then use the KJ method to analysis data to extract the apparent needs of users;On the other hand,conduct in-depth interviews with patients to form user portraits and explore the potential needs of users.Based on the previous research results,this paper puts forward the design strategies that seasonal affective disorder phototherapy products should follow.Firstly,safe and effective: the product have good effect and will not endanger the user health;Secondly,comfortable and portable: the product conforms to ergonomics,compact design and convenient movement;Thirdly,focus on user experience: phototherapy does not affect normal life,and the product is durable and easy to use;Fourthly,pay attention to users’ psychological feelings: humanized design to avoid patients’ sense of shame.Product design practice according to the design strategy: locate the design on wearable phototherapy products and adopt extracranial phototherapy.Firstly,the conditions that meet the safety and effectiveness of extracranial phototherapy are sorted out,and then the ergonomics and component parameters of the product are analyzed.The product use the detachable magnetic suction structure.The child-mother type design is aim to eliminate patients’ shame and improve the user experience.This paper attempts to make a theoretical research on phototherapy products for seasonal affective disorder from the perspective of design.The design strategy has reference value for the future phototherapy products design.Hoping this paper can break the ice in the future research of this field.
