MEET CALVIN. He is a sophomore who just moved overseas into an apartment with 3 other people. He basically has no time for going to the gym, yet still wants to stay fit by exercising at home. Being an impulse buyer, she does not really care about the cost of the jump rope, but just wants it to last long.

REDESIGN PROCESS HANDLE Throughout this process, I worked back and forth with a couple of my stakeholders.

EARLY CONCEPT SKETCHES I brainstormed on my own in regards to the redesign of my jump rope, based on my adjectives and the order of it. From
PROCESS
B O O K
here, I brought these sketches to my stakeholders.
42
TEST I
PROCESS
B O O K
DSID 126
E R G O N O M I C S
Before anything else, I tested the placements of the hand and where a person’s hand would ‘land’ when gripping the handle of the jump rope.
TEST II
Tested on how thin the handles of my jump rope could be. Test ed this in several different positions. I also made this to see how ‘short ’ and how ‘small’ my jump rope handles could be, to emphasize on my ‘compact ’ feature of the jump rope.
44
From the sketches, I tried developing 3 mock-ups, and then used this for testing on my stakholder.
PROCESS
B O O K
DSID 126
E R G O N O M I C S
MOCK UP I
These mock-ups are from 3 different directions. From left to right: organic, semi-organic, non-organic.
REVIEW From the three mock ups, I worked with my stakeholder and reviewed one by one on which one was best and future developments. User says that it is preferred to have a more organic shape for the jump rope handles, and not something that may harm the hand. Having an equal length in diameters would be nice for an easier grip.1

E R G O N O M I C S
MOCK UP II I made more mock ups to elaborate the main design of my handles, and then brought these to my stakeholder.
The indent in this created a less bulkier look, but devel-
PROCESS
B O O K
opments have to be made so that the indent fits right on most hand sizes.
My takeaway from my sketches are just a slimmer and shorter sized handle compared to the current jump rope handle I am redesigning.

REVIEW
Then I worked and evaluated the handles with my

stakeholder, based on adjectives and size.
We carefully focused on particular handles that fit the best, but only to find out that all the handles pretty much felt the same and made no significant difference in the feeling of it.

RESULTS

E R G O N O M I C S
PVC I tried this rope because I was curious - it had water but was still super lightweight. Unfortunately, the material was too thin that there were some scratches after the durability test.
PVC This rope had no problem at all in resisting carpet or wood surfaces.
PROCESS
B O O K
It worked fine. PVC is the material I will use.
Woven/wool This material was the lightest. But I guess PVC won on the durability test. After a couple of spins, this rope got really uncontrollable and
was very uncomfortable to use.
