Lifting the Load Optimizing Dishwasher Ergonomics Through User-Centered Design

Abstract

Dishwashers are a widely used appliance in modern homes, yet their design has seen limited ergonomic innovation in recent decades. Most models remain standing on the floor, requiring users to bend down repeatedly during loading and unloading dishware, leading to physical strain on the back. This study aims to improve the ergonomics of household dishwashers by developing user-centered design solutions, in collaboration with ASKO. Through an iterative design process, the project used a range of methods to analyze the current situation regarding dishwasher ergonomics, gathering both numeric and qualitative data. The data was analyzed leading to the identification of pain points and user needs, and then the development of two ergonomic dishwasher solutions. A contemporary concept and a future concept. The contemporary concept features a built-in scissors lift mechanism in the door, allowing the users to work at an ergonomically optimized height when loading and unloading the dishwasher, where both the upper and lower basket can be reached simultaneously. The future concept features modular baskets that can be removed and moved to a better work height, such as the countertop, with handles for better grip. This concept is a holistic concept that blurs the line between the dishwasher and kitchen storage by providing the possibility to store the baskets directly in drawers and cupboards. Both concepts aim to reduce bending, improve posture, and support usability. Ergonomic evaluations indicate improvements compared to ASKOs dishwashers today, with lower strain on the body in critical tasks when using a dishwasher.
