Design specifications of a heat applicator weed controller device for family farms

ABSTRACT: One of the difficulties faced by organic food farming families is weed management without the application of chemical products. Thus, this study aimed to establish the design specifications for the development of a heat applicator device for small organic family farms. The implemented methodology allowed the division of the project to phases composed by different tasks. This paper addresses the informational phase, which identifies client needs, according to the lifecycle of the product, in order to establish the design specifications. The declared needs of 40 customers were identified and converted to the requirements of 24 clients. This resulted in 26 design specifications, displayed in order of importance, and distributed along the product’s entire life cycle. Nine requirements were considered to be the most important; namely working speed, target applied temperature, application height variables, weed elimination, production costs, operation costs, energy consumption, weight, and main crop damage.

摘要：有机家庭农场面临的核心难题之一，是在不使用化学药剂的前提下开展杂草治理。为此，本研究旨在为小型有机家庭农场开发热力除草装置制定设计规范。所采用的研究方法将项目拆解为包含多项任务的若干阶段。本文聚焦于信息调研阶段，该阶段依据产品全生命周期识别客户需求，以确立设计规范。研究人员识别出40位客户提出的明确诉求，并将其转化为24项客户需求，最终归纳出26项按重要性排序的设计规范，覆盖产品全生命周期各环节。其中9项需求被列为核心关键：分别为作业速度、目标施加热温度、作业高度调节范围、杂草清除效果、生产成本、运营成本、能耗、设备重量以及主栽作物损伤程度。
