1Duration of action of stationary object
If a reusable heating element is used in a vaping device, then the device can be reused multiple times, but the heating element becomes contaminated with saliva and bacteria from the user's mouth, requiring cleaning or replacement
Solution Approach 1:
The heating element is designed as a disposable component that can be easily separated from the reusable vaping device body. This segmentation allows the heating element to be replaced frequently without affecting the main device, solving the contamination problem by enabling easy disposal and replacement of the contaminated component.
Solution Approach 2:
The heating element is designed as a low-cost, disposable component intended for single or limited use. After contamination with saliva and bacteria, it is discarded and replaced with a new one, eliminating the need for cleaning complex heating elements and ensuring hygiene without compromising the reusability of the main device.
2Object-affected harmful factors
If the heating element is designed to be easily replaceable, then contamination can be addressed by frequent replacement, but the device complexity increases
Solution Approach 1:
The heating element is merged with a pre-attached cartridge or container holding the consumable liquid or material. This integration creates a single replaceable unit that combines the heating element with its fuel source, simplifying the replacement process and reducing device complexity while maintaining easy replaceability for contamination control.
Solution Approach 2:
The heating element is designed as a simple, inexpensive disposable component with a straightforward connection mechanism to the device body. This simplicity enables easy replacement without requiring complex tools or procedures, balancing contamination control needs with minimal increase in device complexity.
3Ease of operation
If the heating element is made disposable and inexpensive, then replacement is easier and more frequent, but the manufacturing precision and quality control become more challenging
Solution Approach 1:
The heating element is designed as a simple, segmented component with standardized connection interfaces. This segmentation and standardization enable mass production with consistent quality control, making the disposable element simple enough for easy manufacturing while maintaining reliable electrical and mechanical connections for ease of replacement.
Solution Approach 2:
The heating element is designed with optimized parameters for disposable use, including appropriate material selection, resistance values, and physical dimensions that balance manufacturing feasibility with performance requirements. These parameter optimizations enable cost-effective mass production while ensuring sufficient manufacturing precision for reliable operation and easy replacement.
