Due to consistent cassava cultivation, small-scale processing centers rely heavily on the cassava grater. However, these machines face stagnation in innovation and design evolution, leading to inefficiencies, limited capacity, and inconsistent output. Adding to these challenges is the competitive global market, demanding a focus on design enhancements. This study employs a multi-faceted approach involving the Analytic Hierarchy Process (AHP), Quality Function Deployment (QFD) and Theory of Inventive Problem Solving (TRIZ) to prioritize customer requirements, propose technically aligned solutions, and offer innovative design options for cassava graters. A total of 10 customer requirements (CR), 21 technical solutions (TS), and 63 innovative design options (IDO) were established and prioritized, aiming for easy adoption by fabricators, engineers, manufacturers, and artisans. Implementing these insights boosts cassava grater efficiency and productivity and significantly advances knowledge. This work presents a thorough scientific framework for product design, empowering local manufacturers to remain viable and relevant in the rapidly changing field of product enhancement.
由于木薯种植的持续性，小规模加工中心严重依赖木薯擦碎机。然而，这些机器在创新和设计改进方面停滞不前，导致效率低下、产能有限且产出不一致。全球市场竞争激烈，这使得设计改进成为必要，这也加剧了这些挑战。本研究采用多方面方法，涉及层次分析法（AHP）、质量功能展开（QFD）和发明问题解决理论（TRIZ），以确定客户需求的优先级、提出技术上一致的解决方案，并为木薯擦碎机提供创新设计方案。总共确定并优先排列了10项客户需求（CR）、21项技术解决方案（TS）和63项创新设计方案（IDO），目标是便于制造商、工程师、生产商和工匠采用。实施这些见解可提高木薯擦碎机的效率和生产力，并显著推进相关知识。这项工作为产品设计提供了一个全面的科学框架，使当地制造商在快速变化的产品改进领域中保持活力和相关性。
