Traditional pillows fail to address two critical comfort needs: temperature regulation and adjustable support. In hot climates or during summer, overheating disrupts sleep, worsens insomnia, and aggravates medical conditions such as migraines or multiple sclerosis. Standard pillows also lack adaptability in firmness, leaving users with limited ergonomic options. Current cooling solutions (gel packs, ice pillows, or fans) are either temporary, noisy, or impractical for portable use., The challenge is to design a smart cooling pillow that combines three functions in one:, Cooling system (Peltier module with fan or alternative cooling methods) to maintain a comfortable head and neck temperature., Inflatable TPU bladder to adjust firmness and thickness (3 cm uninflated, 6–8 cm inflated)., Automated control via pressure sensor and microcontroller, ensuring the pillow activates only when in use and shuts off safely after 30 minutes., The solution must be portable, rechargeable, quiet, and safe, with structural safeguards against bursting and electrical hazards. It should balance advanced features with affordability, targeting a retail price of ₹300–₹500 for a basic version., This innovation addresses sleep therapy, medical comfort, and lifestyle needs, offering relief for heat-sensitive patients, travelers, and everyday users seeking better rest. The problem lies in integrating cooling, inflation, and automation into a compact, ergonomic design that remains cost-effective for mass production.
