From previous modeling, I finally have access to some Dycem material, so using this I have developed my jug models to incorporate this and see what effect it could have on the product.
Above is an image of the kinds of rolls of the materials that are currently on the market. The great thing about this material is that it easy to mould with a cutting the Dycem can be done efficiently with a pair of scissors.
To see the non-slip effect of this material, a colleague and I wanted to see how much pull it would take to remove a pool queue from his grip with the material.
Figure 1 and 2 shows the pool cue with no Dycem applied and my colleague holding the cue with a light grip. As you can see I was able to slide the cue out of his grip with little effort. Figure 3 shows the Dycem being applied.
My colleague then applied the same amount of grip as previous. He even says that he can feel a stronger grip on the cue, even though he applied the same level of gripping force as the previous test.
Figure 4 below shows that even after me pulling, the only thing is was moving was the person holding the cue and I was unable to move slide the cue itself out of his grip.
These images shown above are the first developed model of my jug idea, removing the handle all together and simply using Dycem as the gripping point of the jug. This would remove any need for the user to grip onto a handle and the Dycem would provide enough friction so that the user cold tilt the jug with at enough of an angle to decant the liquid inside.
Asking for feedback on this product I was met with response like: What about weight, wont be too heavy to lift when it is full of water? and What about heat, wont it burn if its filled with boiling liquids?
So to do help me understand the capabilities of this material a little further, I attached a sheet of Dycem plastic to a pre-existing jug design, to see if incorporating some sort of handle would help:
I then put boiling water into the jug and asked another colleague to pour the water from the jug into a cup.
Figures 5, 6 and 7 shows the user pouring the water into the cup. This was done slowly as the user thought the grip wouldn’t hold if done too fast. Figure 7 shows the angle at which the jugs grip started to fail. This was not due to the materials lack of grip but the fact the weight of the jug itself has shifted over the point of its centre of gravity.
The following were more comments given by my colleague:
- The heat of the boiling water was bearable but over time and more use it was getting uncomfortable, so using thicker Dycem to remove excess heat would be beneficial.
- Having the handle there was good as it provide support for the hand whilst using the jug, so having something to at least lock in index finger is needed.
- The Dycem material would need to cover enough of the jug to fit the top range of hand sizes.
- Pouring was possible but without the handle the correct angle couldn’t be achieved.
These images shows this developed idea and includes the following:
- A support ‘handle’ so that the fingers can easily slide underneath and be supported when operating the jug.
- A strip of Dycem on the rear of the jug to cover the palm of then hand, providing grip and stability for the user.
- A deep enough area so that people with larger hands can use the jug.
Again collecting feedback from colleagues, here are a few things that need to be worked on for the next development:
- Consider width of the Dycem material to allow grip on the fingers and thumb not just the palm
- Think of the material underneath and how it will attach to the materials.
- Look at the handle and see if it can be made more aesthetically pleasing.
- Could the handle be made to fit the hand perfectly for the user?
This product need further development to come to a much better conclusion and getting a response from those who suffer from arthritis would be beneficial in finding out how they would use the product.
