Abstract

This paper presents the development of a tailored packaging solution for exoskeletons designed for Solat, aimed at optimizing portability and safeguarding during transportation. The objective was to identify user needs and preferences through survey on optimal packaging design solutions for an exoskeleton for Solat. Respondents emphasize features like lightweight materials, easy accessibility, and durability. Design 1, a square hand-carry case, emerged as the preferred choice over Design 2 (roller bag), noted for its simplicity and space-efficient design. Methodologically, a selection matrix analysis utilizing House of Quality (HoQ), concept screening and scoring to finalize design packaging that prioritized protection and portability. The square hand-carry case was identified as optimal, excelling in durability and portability while acknowledging storage limitations. Material selection focused on Polylactic Acid (PLA) due to its lightweight, biodegradable properties and sustainability advantages. The PLA-based hand-carry case addressed specific user needs for ergonomic comfort during short-distance travel to mosques, ensuring robust protection with internal padding and secure straps. Structural analysis using ANSYS validated PLA's suitability under a simulated 4 kg load, demonstrating minimal deformation and stress concentrations within safe operational limits to achieve the designed effectiveness in safeguarding the exoskeleton for Solat. Rapid Upper Limb Assessment (RULA) analyzed designed effectiveness focusing on ergonomic analysis, indicated a low ergonomic risk for both male and female manikins carrying the hand-carry case. Moderate concerns in forearm and wrist-arm areas highlighted the need for ergonomic adjustments, particularly for female users, to enhance prolonged use comfort. The study successfully meeting user needs while providing effective protection. Future improvements could focus on ergonomic enhancements to reduce forearm and wrist strain.
