FREEZEASE
Hands-free modular cryotherapy sleeve for musculoskeletal recovery — comfort, mobility, and continuous cold application on any limb.
Faculty Guides — Dr. Ranjit Konkar · Prof. Ajay Goyal
Cold therapy shouldn't cost you your hands or your mobility.
FREEZEASE is a hands-free cryotherapy solution designed for treating musculoskeletal injuries affecting the upper and lower extremities. The project addresses the inconvenience of conventional ice packs by enabling users to receive cold therapy while maintaining mobility — improving comfort, reducing dependency on holding the ice pack, and enhancing therapeutic efficiency through an ergonomic modular sleeve system.
Problem Space
Where conventional cryotherapy falls short
Hands occupied
Users must continuously hold the ice pack against the affected area.
Restricted movement
Existing solutions limit mobility during therapy sessions.
Poor limb fit
Products aren't optimized for upper and lower extremities.
Ineffective contact
Conventional ice pack shapes don't deliver focused therapeutic contact.
Why It Matters
The wellness landscape today
- Increasing focus on self-care and wellness
- Technological improvements in therapy products
- Growing preference for traditional recovery methods
- Easy accessibility of reusable heating and cooling packs globally
Design Brief
A hands-free ergonomic device for every limb
Engineered for the upper and lower extremities to treat musculoskeletal injuries, muscle soreness, sprains and strains — allowing free movement, integrating into everyday activities, reducing inflammation, and improving recovery through continuous cold application.
