Customer focused optimal design skill training module from the informatics perspective

Design informatics refers to the processing and application of information in the design process. In the case study of Product-Service Bundle (PSB), design analysis has become challenging due to the increasing amount of complex design information. Given such a design complexity, there are challenges in term of technical and educational needs of data-driven design. Therefore, a design skill training module of customer-focused optimal design was proposed. This study was conducted based on four main parts: (a) Part I: The Customer Knowledge Discovery (conjoint analysis and decision tree method); (b) Part II: The PSB Design and Optimisation (multiobjective optimisation technique); (c) Part III: The Design and Development of Training Modules (ADDIE Model) with Experts Validation (n=5); and (d) Part IV: The User Study of Skill Training Module (n=21). As results, in Part I the generated rules for product-service that matching the product and service features were identified. Part II, two case studies that show new PSB pricing reference based on existing offers were illustrated. Then, four modules of customer-focused optimal design training were developed in Part III and the average of expert’s validation score, 70%-85% were obtained which exceeding the suggested acceptable threshold, 70%. Finally, an increment of trainees achievement that obtained ‘A’ grade in each training was recorded in Part IV; 23.81%, 28.57%, 38.10%, and 61.90%, respectively. Besides, the frequencies of trainee’s achievement grades were presented based on demographic profiles; (i) working experiences, with (n=3), without (n=13), and training (n=5); (ii) level of skills; basic (n=6), intermediate (n=12), advanced (n=3), respectively. Lastly, the feedback of post-training survey presented good usability rating and feasibility of the suggested training modules.

Design analysis of open and ducted propellers in UAV application

The aim of the study was to determine the feasibility of implementing a ducted propeller system for small scale drones. 5” propeller drones are common in first person view (FPV) drone racing and cinematography, increasing the likelihood of injury due to untrained pilots, of which the majority are laceration injuries due to the propeller blades. Furthermore, the addition of a duct improves the thrust output of the entire system. A few key parameters are identified, of which were manipulated to determine the optimum values through a series of ANSYS Fluent CFD simulations. Introducing a duct is shown to reduce the lift a propeller produces; however, the reduction is offset by the lift generated by the duct. Blade tip clearance was investigated, with the optimum value found to be 0.25 mm, producing the most lift from the duct and least reduction of propeller lift, and with thrust outputs up to 35.568% more in some cases compared to open propeller. It was observed that increasing the BTC significantly reduced duct lift. Diffuser length simulations provided unconclusive results, with the duct lift varying depending on the diffuser length. However, the optimum diffuser length was determined to be 65 mm with respect to thrust outputs. In comparison, inlet lip radius shows a clear pattern, deviating from the optimum value of 16.5 mm reduces the duct lift produced, with smaller values severely decreasing performance
