消費市場決定產業發展動向，促使產品開發與行銷思維強調以顧客需求為導向，因此能否掌握顧客的需求，成為產品開發成功要件之一。然而，面對現今產品設計上複雜的需求問題，使得設計者很難釐清顧客需求要素之間的關係。有鑑於此，本研究已可調式桌子為例，應用詮釋結構模式探討產品設計顧客需求間的從屬與層級關係，並導出階層式結構圖，可明確得知消費者需求的問題點與目標點，期中問題點有符合人體工學、適合不同用途、方便修復、具收納及調整功能、避免刮傷手腳及衣服等項目；而材料及結構堅固、零件不易鬆脫、使用壽命長、支撐穩固不易翻覆等項目為目標點，藉此成果可行程較清楚的脈絡，以利設計決策上的考量。

Consumer market determines the development trends of industries, thus urging product development and marketing ideas to emphasize orientation of customer requirements. Therefore, whether customer requirements can be grasped has become one of the keys to the success of product development. Nevertheless, when confronted with the complicated demand problems in today's product design, designers find it very difficult to clarify the relationship among the elements of customer requirements. In view of this, the study takes the design of adjustable table for example, and applies interpretative structural modeling to explore the subordinating and hierarchal relationships between product design and customer requirements. Meanwhile, the paper drives a hierarchical structure chart to help designers analyze the relationships among different elements and the order of elements. The research results reveal that through the distribution chart of requirement elements and the structural relationship diagram, the problematic points and target points of customer requirements can be clearly known. Hence, a clearer context is formed for designers to consider well when making design decisions.
