Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a fixed heating element is used, then the device structure is simple, but the heating element ages and contaminates leading to decreased taste quality
Solution Approach 1:
The heating element is divided into a heating portion and a sleeve that can be separated. The heating portion can be detached from the sleeve for independent replacement, allowing the heating element to be segmented into replaceable components that can be maintained separately.
Solution Approach 2:
The heating element transitions from a fixed structure to a dynamic, detachable structure. The heating portion can be removed and replaced independently from the sleeve through a detachable connection mechanism, enabling dynamic maintenance and replacement without replacing the entire heating assembly.
2Volume of moving object
If a fixed heating element is used, then the device is compact, but replacement and cleaning are difficult
Solution Approach 1:
The heating element is segmented into a heating portion and a sleeve that can be separated. This segmentation allows the heating portion to be independently removed for replacement or cleaning while keeping the sleeve in place, facilitating easier maintenance without requiring complete disassembly of the device.
Solution Approach 2:
The detachable connection structure is pre-designed into the heating element, allowing for quick and easy separation of the heating portion from the sleeve when maintenance is needed. This preliminary design of detachable connections enables rapid replacement without complex disassembly procedures.
3Device complexity
If thermal conduction heating is used, then the heating method is simple, but preheating time is long
Solution Approach 1:
The heating method is replaced from thermal conduction to infrared radiation. The heating portion generates infrared light waves that directly heat the aerosol generating substrate without requiring prolonged thermal conduction, significantly reducing preheating time while maintaining heating effectiveness.
Solution Approach 2:
The heating mechanism transitions from conductive heat transfer to radiative heat transfer through infrared radiation. This phase transition in the heating method allows for faster energy transfer to the substrate, reducing the time required to reach operating temperature.
