The humble punching machine hasn’t changed in years.
And yet, it’s still used every day—by students, office workers, and admin teams.
But we asked: What if that daily tool is causing more harm than we think?
Why This Project?
Our concepts focused on ergonomic comfort, simple interaction, and psychological ease.
We prioritized:
Clear button mapping and feedback (visual, audio, tactile)
Portable form with a protective flip-lid and built-in UV sanitization
A wearable device that stores easily inside the monitor itself
The Design Oppurtunity
This wasn’t just a product stuck in time.
It was an ergonomic nightmare hiding in plain sight.
Our user research revealed:
Concept Development
What if comfort was built into the form? We explored over a dozen sketch iterations, each pushing toward one idea: a punch that doesn’t feel like a chore.
Compact design with a flip-lid that doubles as a stand. Front-facing controls ensure easy use, while a built-in UV strip sanitizes the device when closed.
The wearable fits neatly inside the monitor for convenient storage and access.
Mock-up
Design gets sharper in 3D.
Using Fusion360, we translated the final form into a 3D-rendered prototype.
3D Modelling
Uneven Effort:
Men need less force, while women
use both hands
Hard to Punch:
Thick stacks require excessive force
Awkward Use:
Many punch in the air while sitting
causing instability
Too Noisy:
The loud sound is disruptive
Repetitive Strain:
Leads to discomfort and potential
injury
An ergonomically enhanced punching machine for everyday use. Designed to reduce effort, improve grip, and simplify motion.
STEMPEL
