A TRIZ-Inspired Conceptual Development of a Roof Tile Transportation and Inspection System

Abstract

The Indonesian roof tile manufacturing industry relies heavily on manual operations, specifically in transportation and inspection processes, which creates multiple issues, such as fatigue, injuries, human error, and reduced productivity. Various industries in the Indonesian industrial landscape have begun embracing a problem-solving approach known as the theory of inventive problem-solving (TRIZ) to mine solutions for industrial issues. Nevertheless, its application in the Indonesian roof tile manufacturing industry remains unaddressed. The study aims to solve manual handling issues in the roof tile manufacturing industry using TRIZ. Three observations were outlined from manual roof tile transportation and inspection, followed by the formulation of engineering contradictions (ECs). The ECs were linked with system parameters, which were used as indicators within the contradiction matrix to extract inventive principles as solution models for conceptual development. The concept included an automated system with a conveyor belt (#15: dynamics) for effective transportation, automated image capture (#28: mechanics substitution) for effective inspection, and a flipping conveyor (#25: self-service) to eliminate manual contact. Although the study addressed several issues stemming from manual operations, mechanical analysis, prototyping, and usability testing still require improvements.

A TRIZ Approach for Designing a Smart Lighting and Control System for Classrooms Based on Counter Application with Dual PIR Sensors

“…Every responding variable within the contradiction statement is associated with specific system parameters within the TRIZ framework. TRIZ encompasses 40 distinct system parameters (as delineated in Table 2 ), with each parameter denoting a factor that delineates a system, establishes, and confines a system’s performance, or characterizes the attributes of a system [ 25 ].…”

“…Every responding variable within the contradiction statement is associated with specific system parameters within the TRIZ framework. TRIZ encompasses 40 distinct system parameters (as delineated in Table 2), with each parameter denoting a factor that delineates a system, establishes, and confines a system's performance, or characterizes the attributes of a system [25]. Once the appropriate system parameters have been selected for association with the contradiction statement, they serve as indicators that are cross-referenced within the contradiction matrix.…”

An innovative design of mega shaft boring machine (SBM) cutterhead based on TRIZ and AD theory

“…Due to the good complementarity of TRIZ and AD theory, the integrated application of TRIZ, AD theory, and other modern design methods have gradually become the focus of product innovative design research. Ng et al 19 used TRIZ to solve the manual labor contradictions in the roof tile manufacturing industry, and proposed a design concept of automated roof tile transportation and inspection system. Kim et al 20 proposed a conceptual robot design for an automated layout of building structures by integrating QFD and TRIZ, to meet different functional needs and technical requirements compared with the existing ones.…”

“…Although a large amount of research work has used AD and TRIZ theory to carry out product innovative design, but they are oriented to different stages in the design process, and different theoretical tools are used to solve problems. [26][27][28] Some studies mainly focus on creative design [19][20][21] or detailed scheme design 22,23 of new products. Most of the above studies only generate one feasible scheme.…”
