Lab 2: “Prototype Design”

Prototype Design


This is a pain relieving thermal therapy device that is designed for comfort and portability. The device fluctuates from cooling and heating to provide maximum pain relief for people of all ages. This device is effective, safe, and it is able to easily target areas of the body that are in need of the therapy. Although the target market for this device is physical therapy, this thermal therapy product can be used for many reasons including post-surgical recovery, sports medicine, pain management, in-hospital treatment, and physiotherapy. The device comes with a screen on the front which makes changing the temperature and settings simple. An app will also be developed alongside this device so that the physician or physical therapist of the patient can set and monitor the course of treatment conveniently.

Technical Feasibility

Technical Feasibility

a. What are the technologies needed?

The technologies needed for this device include thermoelectric heating and cooling. Thermoelectric heating/cooling uses the Peltier Effect, which is a change in temperature created through applying a voltage between two electrodes. Usually in a device that uses the Peltier Effect, the electrodes are made out of a metal with good electrical conductivity (Rouse, 2008). Using thermoelectric technologies allows the patient to cool and heat different areas of the body without the harsh temperature of ice and with therapeutic heat easily.

b. What are the challenges?

A challenge in the technical feasibility of this product is making the device alternate from heating to cooling and vice-versa with ease. The goal for the product is for the patient to be able to change the temperature of their portable device efficiently and safely without any complications. This device will also be connected to an app which the patient’s physician or physical therapist is able to monitor the progress and set the temperature as needed. This could be seen as a possible challenge in regards to technical feasibility.

c. What could go wrong?

There could be potential issues for this product when it comes to switching between heating and cooling with ease. However, with the right technologies enforced, the device should be able to function efficiently at any set temperature. There could also be technological error in regards to connecting the device to the app. This is why testing will occur in order for the device to function to its safest and most productive abilities.

Clinical Feasibility

Clinical Feasibility.

a. Will it work in the clinic?

The thermal therapy device that will be presented will work in most clinical environments only if tested properly. Once it is considered suitable for marketing, it will be used for treating minor or severe muscular pains where the patient will have several days of treatment. This device will play an important role in physical therapies since it is capable of treating the damaged tissue with heating and cooling features. For instance, Chronic back pain; patients who suffer chronic back pain must undergo chiropractic care, physical therapy, and medication. This product will facilitate any kind of pain although it may not be suitable for anyone who decides to use it. Clinics will benefit of the product’s ability to monitor and treat the pain without the necessity of the patient to transport to the clinic itself. When used correctly, this product will provide relief from back pain, neck pain, and any kind of physical pain from the comfort of home. Therefore, yes, it will work in the clinic, but the patient must ask opinion of a medical professional to avoid worsening of pain.

b. What are the clinical risks?

The clinical risks of this device include, defectiveness, damage to the patient, and malfunction of the program. Since it is a wireless dependent product, the risks of it not working depend much on how properly it is used when treating the physical problem. The majority of the main problems of a device are due to the malfunction of the program itself. Which is not something that will potentially impede the whole device to function properly, but it is something to keep in mind. Apart from defectiveness, there is also a probability of worsening the pain of a patient instead of healing it with its features. As mentioned in technical feasibility, there is a chance of the product misinterpreting the desired function, but then again, it is not something that can’t be fixed with a few programing reset of the product.

c. Have similar products been in a clinical trial? How long was the trial?

Yes, there are plenty of similar products that have been in a clinical trial for this type of device. For instance, “Quell”; “Quell” is a drug free pain relief device that claims to resolve nerve pain, arthritic and joint pain, leg and foot pain, widespread pain, and lower back pain. Quell serves as an example for our product since it is clinically proven and FDA approved. The investigation took about a year in clinical trials and it was tested in people with chronic musculoskeletal low back pain. It had specific criteria in which only 21 and above patients with axial musculoskeletal pain were tested, and have had pain for more than 3 months. Both Quell and our thermal therapy device are similar because they both adjust therapy for optimal relief, wireless, and available for 24/7 therapy on patients.

Technical Feasibility

The Thermal Therapy device scores a 3 out of 3 for technical feasibility since a product very similar to it has already been created. Though the concept of the competing product is more or less the same as the Thermal Therapy pad, installing the wireless feature is not a significant obstacle to overcome in the manufacturing process. The device has a very straightforward design with many already known materials.

Clinical Feasibility

For clinical feasibility, the TT pad earns a 2 out of 3 because customer approval of this specific product has yet to be conducted and collected. While devices very similar to it have been well received by customers in the home-remedy healing market. A slight risk posed by the wireless feature of the pad includes the potential for the timing of the pad to get off its set schedule. For instance, customers could have the pad timed to turn on while they are sleeping, and if it does not shut off when it should it could pose a risk to them. Since they are dependent on the pad turning on and off independently, they may go to bed without having to worry about turning it off like they would expect to with a pad that needs to be plugged in.

Value of Prototype to Customer

Customers generally evaluate a product or service based on the value vs. the price that it is being asked for. Therefore, the thermal therapy device that we will be presenting to our customers will provide a more portable and electronically convenient method for healing and cooling therapy. The device will ease the patient’s condition by retrieving specific prescriptions from their physicians/physical therapists via the mobile app. The adjustable temperature of the device provides therapeutic benefits to those physically injured while successfully increasing their range of motion.

Cost to Create

Cost to Create

The determined cost to create the thermal therapy device will be moderately more expensive than the usual heating and cooling devices since it is a more efficient health solution that combines two products into one. A generic cooling machine is worth 50 dollars compared to any higher-demand form of treatments generally worth 300 dollars. Same applies to generic thermal therapy devices. Generic heating machines are worth an average of 200 dollars, but our thermal therapy device will cost an average of 125 dollars to assemble. Thus, making it a product worth the purchase.

Anticipated Average Sale Price' (ASP)

The anticipated average sale price would come out to $500.00. The manufacture price of the product would cost $100. In order for the device to perform both tasks of cooling and heating in such a portable manner, the product will cost more to manufacture than a basic heating/cooling device. In order to retrieve the sale price, the manufacture price was multiplied by 5. The total cost comes out to $625.

Market Size (in dollars per year)

The initial market size for the physical therapy field is about 200,000,000. $500 x 0.05 x 200,000,000 = $5,000,000,000 (sale price x penetrance x number of customers)



Based on the fundability worksheet, our prototype should be funded. The physical therapy market size is significantly large enough to keep the product active in the market. The price of the device is reasonably priced compared to its competitors, while still maximizing its efficiency and portability. Other products/devices that relate to this device have been very successful. Therefore, clinical feasibility is not an issue for this product. People of all age ranges and backgrounds are qualified to use this device. Whether an athlete needs relief after an injury or an elderly person needs to find comfort with aches and pain, this device will provide alleviation and comfort.
