Abstract: To fast and accurate ergonomic product design at the design stage, the E/HOQ/TRIZ
integration model is developed and the specific steps are described. The method of obtaining user
needs based on the ergonomics (E) user needs three-dimensional classification was described. The
key issues and the key design areas of ergonomic design were established by the house of quality
(HOQ). The type of conflicts of the key issues were analyzed and resolved by the theory of inventive
problem solving (TRIZ) for achieving ergonomic product innovation. E/HOQ/TRIZ integration model
can effectively make up the limitations of the single design theory and method, and play the
advantages of the three theories and methods, so as to realize the innovative design of human machine
products. Finally, through innovative design of the ergonomic bath facilities, the feasibility of the
proposed integrated model and approach was demonstrated.

Key words: ergonomics, house of quality, theory of inventive problem solving, integrated model;
