GN Project – Iteration Report

The electronics team led by Nichola Tali, Engineering Lab Coordinator at Ashesi University College worked on the creating a working prototype for one of the product solutions that were settled on-the vein finder.

The vein finder prototype was done with red LEDs and tested. The team recorded success in seeing veins when a palm is placed over the lights. However, when the arm is moved further over the lights, veins become less and close to unseen. This is attributed to the increased thickness of muscles. For fair/light skinned people, veins were much more easily seen than when the vein finder was used on dark skinned people. Following this

For fair/light skinned people, veins were much more easily seen than when the vein finder was used on dark skinned people. Following this insight, we changed the light source from red LEDs to infrared light. Infrared light has a greater ability to penetrate the skin and will make viewing veins easier regardless of skin colour. Replacing the red LEDs with infrared LEDs and using a different approach to circuitry, we will explore how efficient we can create a sustainable device.

Goal

The goal of this project was to do research into the health sector, using design thinking, to find opportunities where GN electronics can introduce products into the Ghanaian market.

 

Research

The research was done in three phases. The first phase was aimed at identifying 6 opportunity areas where GN electronics could enter the health market with an electronic product. Three of the six areas would be selected after which the second phase of the research would identify 6 possible products, two from each area, that GN Electronics could produce. One of the six would be selected for further research and prototyping.

A stakeholder map was developed to identify the key stakeholders in the health space. General practitioners and patients (the users in the health sector) were identified as the most active stakeholders and were, therefore, the focus of the research. This decision was arrived at because most health problems experienced by patients are sent to general practitioners before referrals are made to specialists if necessary.

Interviews and questionnaires were used to sample the views of the two major stakeholders. The questionnaires were aimed at getting responses from a large section of the stakeholders in order to estimate the major problems in the space. Interviews were then used on a smaller scale to gain a deeper understanding of the identified problems.

The questionnaires used in the first two phases of the research were designed to illicit responses about problems patients and health practitioners face. The questions were open ended thereby encouraging respondents to give more information. The third phase of research was designed to measure the desirability of the vein finder and the vital kiosk in order to decide on one of the two. The questionnaire for this research contained a list of Microsoft reaction words from which the respondents chose those that best described the products. This was followed by an open ended question on what the design may have failed to capture.

 

Analysis

The analysis for all phases of the research was done with card sorting. This applied to the open ended questions which needed to be categorized for further analysis. The same analysis method was also applied to the Microsoft reaction words which was were used in the final phase. The words were categorized into clusters that eased the process of understanding how users perceived the products we presented. For example, it was possible to determine if a respondent thought a product was desirable if the words selected fall under the category “desirable.”

 

Approach

The process of narrowing down on a suitable product was iterative and combined the inputs of the research teams and the major stakeholders of GN Electronics. In the first part of the research, 6 opportunity areas were identified of which GN Electronics chose 3 for further research. One of the major considerations for selecting the opportunity areas was avoiding areas that dealt with emergencies. The reason being that more experience in the health sector would be necessary before working with on technologies for use in life and death situations.

The second phase of the research involved narrowing down on the 3 fields and coming up with two ideas for each field to make a total of 6 ideas. The initial intention at this point was to choose one of the products for further research after which a prototype would be built. However, two of the products were identified to have high potential on the market and were therefore selected for further research and prototyping. The chosen products were the vital kiosk and the vein finder.

The vein finder, as the name suggests, is a device that helps phlebotomists’ locate veins in order to draw blood. This would be applicable in situations where veins are not clearly visible. The vital kiosk, on the other hand, was envisioned as a structure capable of measuring various vital signs, like temperature and heart rate simultaneously. This was meant to speed up the process at the OPD as well as provide a basic means of remote diagnosis for under privileged communities.

After the two products were chosen, members of the electronics club were brought on board to build the first prototypes. After the prototypes were presented to GN Electronics it was decided that the vein finder had more potential on the market considering the data collected from both health practitioners and users. It was evident that the vein finder would solve a basic problem that would improve the experience of patients. Currently, a working prototype of the vein finder has been built by the electronics club in preparation for the final presentation with GN Electronics.

 

 

GN Electronics Product Design and Development 2017 Summer Project Description

Title: Ashesi Design Lab (D:lab)/GN Electronics Design Thinking Project (Summer 2017)

Overview (GN Electronics):

GN Electronics, a subsidiary of Groupe Nduom, is a Ghanaian company located in Elmina, in the Central Region of Ghana. GN Electronics assembles electronic products including set top boxes, televisions, and soon a variety of household products.

Overview (Ashesi Design Lab):

The Ashesi Design Lab is an initiative which combines the concepts of design thinking and design making; design thinking or strategy design for problem-solving, and design making or fabrication for making things more tangible and building out the creative outcomes of the different processes involved in both concepts.

Project Scope:

The D:Lab is exploring a partnership with GN Electronics to conduct Design Thinking Projects aimed at discovering the electronics products within the health sector that GN Electronics can build locally. We propose to apply design thinking tools to develop a solution that meets the needs of users in the health industry. The project will be divided into two periods, the first (6 weeks) will be focused on research and product development and the next (4 weeks) will be a hands-on practice with the electronics club at Ashesi University.

For the first 6 weeks, d:lab interns will do research and identify opportunity areas in the health sector that GN electronics can explore and develop prototypes to be tested. For the next 4 weeks, the electronics club at Ashesi will develop tangible, working prototypes for GN electronics.

Project Details:

Project Start Date: 22nd May 2017

May 22: Research and observations to identify opportunity areas GN electronics can explore. Data gathered will also be analysed using design thinking analysis frameworks. Write a brief report on findings and insights to back 6 areas of need which can be explored by GN Electronics.

June 12 (Presentation 1): Interns present 6 opportunity areas to GN electronics. GN electronics will select 3 opportunity areas for interns to explore further.

June 19 (Presentation 2): Interns will present 2 ideas for each opportunity area identified. There will be 6 ideas for GN to rank.

June 26:  Prototypes will be developed and interns will prepare documents for the electronics club to work on. Hand over ideas and documentation of product designs to Nicholas’ team The document will entail product specifications and requirement definitions for the electronics club to use to develop a tangible product or solutions.

June 7: Package shared with GN electronics and the electronics club

July 10 – August 10: The electronics club work on actual tangible products to present to GN Electronics

August 11: The electronics club/team travel to Elmina to present their solutions and designs to GN electronics.

Project End Date: 11th August 2017
