Designers aim to create designs that resonate with users, the consumers. However, there is often a gap between the sensory and emotional “words” expressed by users and the “words” understood by designers. To address this issue, we propose a method called “Language-based engineering” to reflect the meanings users seek in designs accurately. Using the packaging design of golf gloves as an example, we conducted a survey on six sensory words (I want to pick up, novel, visible, cool, cute, luxurious) to gather user feedback. We analyzed the relationship between user ratings and design elements using Quantification Theory Type I and created a database of these relationships. Furthermore, we converted the sensory word ratings into aspiration levels using the satisficing trade-off method and proposed a method to determine the combination of design elements that satisfy these desired levels as a multi-objective optimization problem. We conducted trade-off analyses on all 30 patterns of the six sensory words to identify the trade-off relationships based on users’ impressions of the packaging design. Additionally, we presented design examples and guidelines that align with users’ sensibilities by combining design elements that meet the aspiration levels.
