The plan is to create a variety of sizes from 1 inch, 2 inch and 3 inch grips. This allows for a easier and quicker grip strength progression. This is because different grip strengths differentiating from small too large allows your grip to slowly transition for a better grip strength.

Since I have not had much experience using machines in the workshop I concluded that I need to get more familiar with them in the timeframe needed Basic tasks like turning and threading can take longer to learn. Also, designing the built in collar is very difficult involving using CAD making the design and then put it into a real-world scenario will probably at least take 6 hours. In a likely scenario I will spend alot of time measuring, setting up and troubleshooting the product when in the process of construction.

I have made a new advancement finding out that certain rubbers which construct the grip mechanism may cause dermatitis. This is a setback which needs to be addressed as dermatitis can be dangerous and even life threatening in certain conditions. I have concluded on doing more research on this matter for finding the best brand and type of rubber to use. This consists of non-corrosive, non-slippy and strong material.

# data[].attributes.body
Non virgin rubber - costs friendly and although it can not be pure but, most normal everyday users use this product.

Virgin Rubber is the best rubber as it is in its purest form. This leads to less odour, cleaner and longer lifespan. Although this option leads to a higher price point and if a cleaning solution is frequently used to clean the rubber it may decompose.

I looked into Fat Grips Pro grips, designed for enhancing grip strength and muscle development, are typically made from high-density rubber materials. However, the exact formulation used by the company is proprietary, and they usually don’t disclose specifics about the rubber compound. But we can infer a few characteristics based on similar products and the required features:

# data[].attributes.body
TPU because it is grippy, flexible, non contact-dermatitus and it is very durable so it is perfect for use with dumbbells. TPU is also very cheap making it perfect for this scenario.

# data[].attributes.body
TPE and Silicone are typically made for dumbbells but, in this case they are not suited because of they cannot be made with 3d printing machines posing a problem. However, the solution for this which is just as good is TPU as it is just as strong and can be made through 3D printing machines.

Certain metals cause friction, cannot carry heavy weights and are not sturdy. This poses a problem as fitting the weights on the dumbbell is crucial. However, to work around this I did all- rounded research regarding different metals which fit my requirements. I concluded that the metal cast-iron suits the project the best.

SWOT ANALYSIS

Potential weaknesses of the dumbbell, in this case dumbbells require a moderate amount of experience posing potential lack of skill. Firstly, shaping, cutting and detailing the steel for the dumbbell could pose difficulty when considering that the creator has not had experience with the tools needed in the component process. Secondly, organising, shaping and adding TPU plastic grips which actually fit the steel could be time intensive and pose risk of not completing the project purely from lack of experience.

The £100 limitations of the budget will be exceeded in this component as the steel material alone almost fills the whole budget.

The weight of the materials may pose problems with handling and moving the raw components in the workshop. The risk of injury is prominent in this case as raw materials can be sharp and corrosive when not properly smoothed or cut.

The benefits of the component include the offer of a TPU changeable grip which is beginner friendly also allowing for a comfortable grip. This design is much better than other grip strength-based grip implementation solely because of how it is comfortable allowing for reduction of injury. Therefore, stopping potential injuries like arthritis when using them in intense use.

The design is all-encompassed because it allows beginners to understand which grip is best for them regarding their strength and allowing for a tool where they can improve quicker with strength.

The market potential could be comfort and changeability because most grips in the market do not focus on comfort. Therefore, allowing for a grip which can fill a gap which customers in the market want.

Also, another way to reduce the cost of the product is recycle the leftover scraps which the machines and the TPU waste.

The potential threats include the availability of the machines needed to make the product especially with using metals as tools as such because they are more popular especially with tasks like using the 3D printer to create the grips.

In a case where the grips are the wrong size it would pose time-constraint risks and hinder the overall process of making the component. The whole design relies heavily on the TPU grips as the market already has multiple designs with comfortable grips and well-working dumbbells. This makes a potential threat as without the different size grips the project will be insufficient because of its lack of individuality.

Given my lack of experience in the workshop operating the machines may strike up a problem facing a learning curve as understanding the use of TPU and Steel should not be underestimated.

Implementing Silicon Grip Tape would immensely help with the grip, referring to the natural grip before adding different grip sizes. Firstly, it improves the way you hold the weight making it easier, which allows you to lift heavier weights. Secondly, it helps for hand comfortability allowing for less blisters and improved overall duration you can use the dumbbells. Thirdly, unlike the normal metal dumbbell which becomes prone to slipping during a sweaty workout, silicone resists moisture allowing it to stay in place during sweaty workouts. Fourthly, The cushioning tape can help reduce shock from intense activities reducing hand fatigue. Moreover, Silicone is easy to clean, maintain and use. Also, being easy to apply and cut onto the dumbell.

After researching I have found a new problem I need to take in consideration which is the grip wearing down from overuse.

A solution for this is to implement a grippy pattern inside the TPU grip for to stop slipping. However, this solution is difficult as it involves using CAD where invert pattern creating is not meant to be done. This poses a problem as this cannot be done with consistency making it unreliable.

Other possible grip solutions 17/10/2024

# data[].attributes.body
Using magnets on the inside of the original dumbbell piece and attaching them to the grip for a suction force. This would perfectly work as a fix for the grip from slipping as it employs a suction force powerful enough to keep the grip in place but, can still be exchanged for different size grips. However, this cannot be done in the college workshop making it a invaluable solution. This is because the workshop does not have any tool which does different carvings inside the dumbbell. Therefore, the workshop would need an Internal turning tool which it does not have.

# data[].attributes.body
The final product is wrapping Silicone Grip Tape to help add a grippy texture. This solution works due to the co-friendly nature with plastics like TPU producing a tight and long lasting grip without the grip slipping. Silicone Wrap also, helps prevent shock as it creates a cushion between the wielder and the dumbbell. Also, it boosts the longevity of the product, helps reduce fatigue with the wielder and is comfortable.

I have estimated the weight of the bar which holds the weights of the dumbbell through the calculation. "Weight = Width × Length × Thickness × 0.2836". This allowed me to calculate the weight being (5.51+5.51+4.72)x(1.38)x(1.10)x(0.2836) which calculates as 6.5824. This weight is above the average 5 kg which is excellent for a dumbbell

This is proven through its use in public gyms in which it withstands drops from high heights onto the floor when people drop them after there workout. Secondly, Stainless Steel does not rust over time and doesn't change in shape after the initial form unlike other metals. Thirdly, Stainless Steel is not too heavy a metal which allows more diversity in different weight sizes making it easier to gain strength when working out. Fourthly, Stainless steel can be formed into different shapes because it is malleable.

Reason: After doing research on the most optimal dumbbell length it has been proven that the previous 18 inches or 460mm is too large and is for power lifting not for basic exercises like curls, lateral raises and triceps extensions proving inadequate.

I went down to the college workshop and asked the main worker for a reference for the cheapest and best metal for making dumbbells and he referenced me to https://www.expressmetals.co.uk/get-in-touch/ as they give the cheapest steel and that's where he gets them from.

The tested grip was a success and there was minimal flailing of the grip and no printing errors in the test grip. Therefore, because of how occupied the 3d printer is with other users and the minimal time left to execute the project. I decided to use the  grip made as it proved to meet my requirements of strength, flexibility and aesthetics.

The ninja flex orange TPU proved a success so I used it for both smaller grips consisting of 2 consecutive 7 hour sessions. This was because of ninja flexes innate ability for flexibility and strength. Although I kept the large grip which was made from Martin's TPU as it made the different sizes more distinguishable due to its different blue colour compared to the other orange ninja flex colour of the smaller grips.

I took pictures of the grips successfully conveying all the needed angles for a proper view of the different sizes and gave my Lecturer Huw Raine an assignment of the progress I have completed up to this date. His feedback was that I was doing adequately. Although, he said that I needed to start cutting the steel.

I ran into a problem faced from the transportation of the steel as it is large and heavy occupying a large amount of space. After studying how I could transport this safely and effectively, I concluded that I could hold onto it while transporting it through the bus. Also, no problem was faced with the Ninja Flex TPU because of its small compact size I was able to transport it through my backpack.

I transported the steel through the bus system and gave my lecturer Huw Raine, the plans I have to cut the steel and asked for who can help as I have minimal experience with the workshop tools posing a problem of skill. Therefore, requiring help to proceed in the processes needed to cut the steel bar.

I organised a time to meet with Zac the workshop engineer to discuss when he is free to help be cut the steel through verbal communication. The time we concluded was 3:30 to 4:30 in the evening on a Wednesday giving me enough time to work on the documentation on my project among other assignments before the due date of 07/05/2025 when I could cut the steel.

# data[].attributes.headline
I took pictures of the steel in different angles showing its length and thickness. This had to be done before it was cut as it shows the difference of before and after allowing a better understanding of the change of aesthetics providing evidence of improvement.
