Detachable Components: The trash can should feature a design where the lid and base can be easily detached for convenient cleaning and maintenance. This allows users to clean both components thoroughly and ensures hygiene. Collapsible Central Column: Integrate a collapsible central column into the design to reduce the volume of the trash can when not in use. This collapsible feature allows for easy storage and transportation, optimizing space usage. Sensor-based Automatic Opening Lid: Retain the sensor-based automatic opening lid functionality as previously described. The lid should still open automatically when the user approaches, enhancing convenience and hands-free operation. Battery or Power Supply: Ensure the trash can is equipped with a suitable power source for the automatic opening lid feature. Consider integrating a rechargeable battery or providing options for external power supply. Durability and Stability: Despite the collapsible feature, prioritize durability and stability in the design. The trash can should maintain its structural integrity and stability even when the central column is collapsed or expanded. User-friendly Design: Design the trash can with user-friendly features such as ergonomic handles, smooth edges, and intuitive controls. The collapsible mechanism should be easy to operate without compromising functionality.
