In the view of the development trend of small-sized house type and space conflicts with excessive volume of professional ironing equipment, this study intends to develop the multi-function expansion of household ironing table and feasibility of spatial intensification based on the intensive concept. Combining with the kansei evaluation, this study discusses on how to transform household model to deeper vertical compound. In terms of technical means, it cleverly integrates the axial fan, PTC heating plate and other ironing products into household products, in order to realise the self-suction, drying, setting and other functions. In terms of design methods, it generates the prototype of multi-purpose household ironing board through a two-step experiment. Comparing the prototype with other household ironing tools, it not only realises the preliminary conception of function expansion and spatial intensification but also improve the composite utilisation value of raw materials and accessories. Overall, it has provided practical reference for green innovation concept.
