Applied Quality Function Deployment (Qfd) for Elongated Chair Design

Abstract

In line with the times, the need for product development ideas has a high selling value. Economic value and product efficiency are highly considered in the design, one of which is the design of a stall or café chair. In general, the most used seats are permanent. In other words, it can't adjust when used for a few people or for a lot of people. Therefore it is necessary to design stalls and café chairs that can be stretched or shortened automatically. The purpose of designing this elongated chair is, it can be arranged so that it can be shortened, with this advantage we can save space and expand the space and of course it will be designed according to consumer needs. The elongated chair is made using the Quality Function Deployment (QFD) method. Some methods that must be done, namely the Voice of Customer collection phase, which is done by distributing questionnaires to 25 respondents. The next step is House of Quality based on the results of the questionnaire. After the HOQ is completed, then the analysis and implementation phase of the results obtained at HOQ will be applied to the product design.

Designing and Simulation Assessment of a Chair Attachment Air Blowing Methods to Enhance the Safety of Prolonged Sitting

“…After analyzing the prior literature [7,[36][37][38][39][40][41][42][43][44] to extract the evaluation criteria of the proposed design and making some modifications to them, the most valuable criteria that are consistent with the studied designs will be introduced as follows. Performance: it introduces the time of puffing the air cell.…”
