Role: Lead Mechanical Designer & Cross-Functional Technical Coordinator
Core Complexity: Integrating two independent cooling systems (refrigerator + freezer) with interdependent functionalities into a single, unified.

Unique Engineering Challenges & Solutions:
1- Dual Cooling System with Complex Interaction:
 Challenge: Implementing a single inverter compressor to serve both
compartments, coupled with a dedicated chilled-water system. Water was cooled
in the refrigerator section but dispensed through a dedicated outlet on the freezer
door.
 Solution: Designed an intelligent refrigerant circuit and piping layout to manage
disparate thermal loads while routing chilled water to the freezer dispenser without
compromising core cooling performance.
2- Unconventional Defrost System for the Refrigerator:
 Challenge: The refrigerator’s evaporator lacked a conventional electrical
defrost heater. Defrosting had to be achieved via an alternative method synchronized
with the overall system.
 Solution: Engineered a hot-gas defrost cycle (or leveraged the inverter
compressor’s reverse cycle) for frost removal, requiring precise control logic and
seamless coordination with the freezer’s operation.

3- Primary Challenge: Intensive Cross-Functional Alignment:

Challenge:Aligningdesign, production, and quality control teamson these novel and non-standard technologies. Each department had distinct concerns (manufacturability, long-term reliability, cost).

Solution: Led and facilitated multiple structured brainstorming sessions and joint technical reviews to build consensus on the final design, technical documentation, and validation protocols.

Outcome: Successfully delivered an advanced, mass-production-ready product that transformed technical complexity into a user-facing advantage. This achievement was possible only through exceptional cross-team coordination and creative problem-solving.
