Additive Methods

Purpose of research. Accuracy improving of product forming additive methods is described in the paper. Analysis is carried out; new device design for product forming by additive methods is done on the basis of parallel-serial structure mechanisms. This device design provides rigidity of technological system, increased accuracy of final element positioning of forming system, thus expanding technological capabilities of additive formation.Methods. Formation of parts surfaces by additive methods is characterized by high formation error size (approximation).  It is necessary to ensure orientation of the surface in order to reduce the size at which normal will coincide with the axis of forming system final link at formed surface point. The paper presents results of the analysis aimed at existing structures installation of additive forming devices on the basis of parallel-serial structure mechanisms ensuring high accuracy of final link positioning of forming system.Results. Device design for additive product forming according to 3DMP technology - technology of additive forming with electric arc in protective gases, application of which provides high accuracy of final link positioning of forming system, excludes possibility of rigid consumable material jamming in the form of wire due to design of supply mechanism, which is rigidly fixed on the device base for additive forming.Conclusion. Application of developed device design will make it possible to eliminate disadvantages of existing devices for additive forming, to ensure accuracy of final link positioning of forming system for additive equipment, to exclude possibility of rigid consumable material jamming, thus expanding application field of additive technologies.

Insulin Pens

Background: Diabetes affects people of all ages regardless of gender and geographical location. A diabetic patient unlike other diseases; may appear healthy and living a normal life under medication. Therefore a tendency of being noncompliant with medicine especially insulin dosage is observed. One of the reasons of such behavior is that patients find it irritating to use syringes or injections. It results into complications in other body functions such as heart, kidneys, liver and loss of immunity. Results: Dimensional, performance and economic features were compared with existing devices. Device was designed to use standard accessories of needles and insulin cartridges available in market. It was observed that the new device fared well with current devices and provided additional benefits of convenience of use and portability of carrying along being half the size of others. Its overall cost was also substantially reduced due to use of replaceable insulin cartridges as compared to syringes and pens that are discarded after use. Conclusions: A keychain held insulin administration device was successfully developed in this research. Patients could use this device to administer insulin everywhere to ensure timely dosage. Patients are able to carry it along and develop compliant behavior towards insulin usage. Its geometric as well as performance specifications were developed on the basis of syringes and typical insulin pens available in market. Final design fulfilled all the requirements provided by market held devices besides being half the geometric size of regular pens. It uses insulin tubes which can be discarded and device can be used again and again that makes it more economical. Both type 1 and 2 patients can use it because of simple assembly and operation. Prototype devices were used by two patients over a period of 12 weeks who confirmed its satisfac-tory performance. Addition of digital measurement scale was proposed for which further research is in process. Its small size as compared to insulin pens and syringes provided possibility of carrying it in keychain. Methods: Present research was conducted to design and manufacture a keychain held insulin injectable device. Patients requirements were collected through interviews regarding current devices such as syringes, insulin pens and insulin pump. Its geometric features and possibility of carrying along everywhere was the primary focus of these interviews. Patients ease of use, cost, dimensional and performance specifications of these devices were reviewed and considered as target benchmarks for new device design. A set of parameters was established from the collected information that was considered as baseline for new device design. A detailed product design and development process was followed to arrive at final design. Prototypes were developed and tested on few volunteer patients who confirmed its performance and usability advantages with reference to other devices.

As designers of mobile/media-rich devices continue to incorporate more features/functionality, the evolution of interfaces will become more complex. Meanwhile, users cognitive models must be aligned with new device capabilities and corresponding physical affordances. In this paper, the authors argue that based on HCI design theory, users approach objects by building mental models starting with physical appearance. Findings suggest that users who embrace a device’s multifunctionality are prevented from taking full advantage of an array of features due to an apparent cognitive constraint caused by a lack of physical controls. The authors submit that this problem stems from established mental models and past associated behaviors of both mobile and non-mobile interactive devices. In conclusion, users expressed a preference for immediate access and use of certain physical device controls within a multi-tasking environment, suggesting that as mobile computing becomes more prevalent, physical affordances in multifunctional devices may remain or increase in importance.
