Week 4

Week 4 is Eidul Fitri ceremony week.
A little progress was done during this week by designing the sensor (potentiometer) holder that needed to be attached on the surface of the mechanical part.
This is important element for this overall project because the sensor act as feedback for micro-controller to operate. Without it, the ROM cannot be measured correctly.
This is basic sketch for the sensor holder

Week 3

For electronics circuit, I have done some research on what components that are related this project during previous semester. But this time, the research is more toward on micro-controller circuit which is Arduino board. These are components that I have bought for testing the project. All the components are bought at Jalan Pasar near Pudu.

List of components:

1.   Potentiometer
2.   Push buttons
3.   Crystal 16Mhz
4.   Resistor
5.   Ceramic capacitors
6.   Electrolytic capacitors
7.   Liquid Crystal Display (LCD)
8.   Light Emitting Diode (LED), variable colours
9.   H-bridge (IC L293D)
10. 5V voltage regulator
11. 12V 1A adapter
12. DC jack for adapter

Week 2

For the construction of mechanical parts, I have consult with the 3rd party person, which is Mr. Fitri that has specialization doing steel works.
He ask for duration to designing the mechanical parts into AutoCAD (Computer Aided Design) for 2~3 week(s).
I agreed to deal with him by conditions to follow the design of the sketch.

Degree Semester 2, Week 1

For this week, I have sketch the mechanical structure for KJT device.
It is consists of bearing, screw shaft, ball nut, hinge, guiding set, and others.
All were made from mild steel because it is to reduce cost as to achieve the main purpose for this project.
I have measured all the length of leg parts for common people.
By referring to measurement that has been done, the first sketch was to shown the basic concept for leg movement or motion during treatment.
The second sketch is the re-improved sketch after doing some discussion with supervisor.

Week 14

Knee Joint Therapy cost:

Based on some survey that I have done through the internet, I have list down all the components that related with KJT device. After some consideration on wage cost and mechanical frame/structure, I have set estimated price because the cost is dependant on labour and type of material used. These are the budget for each components in KJT device:

Week 12

KJT device benefits/contibutions for soicial environment:

Portability: These machines are light weight and can be used from hospital bed. Upon discharge from the hospital, a range of motion machine can be use at home.

Decreased Recovery Time: The constant slow motion of the machine can help reduce pain and swelling while soothing the joint. The range of motion machine will help reduce soft tissue stiffness, decrease the likelihood of developing scar tissue, promote healing of the joint's surface, and increase the circulation of blood throughout the affected joint.

Increased Range of Motion: The machine is used to maintain range of motion and the flexibility. This machine can help enhance the overall outcome of patient surgery, which supports the ability to perform daily tasks and activities that enjoy to the fullest extent. 

Green environmental: By using stainless steel material, the KJT device frame and mechanical structure were expected to constructed using high quality material. The reason why those material was used is because to prevent user or patient from any corrosion that can lead into virus and bacteria exposure.

Low cost: Most of all device that similar with KJT device were very expensive. The price range based on research is starting from RM 4,000 to RM 11,000. This device was expected to be low cost and target market is for home use and prototyping for research knee anatomy and parameters.
