Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wick made of fiberglass is used to transport liquid to the heating wire, then the liquid transport function is achieved, but the fiberglass fibers easily break and users may inhale fiber fragments
Solution Approach 1:
The patent removes the wick component entirely from the system. Instead of using a wick to transport liquid, the invention directly contacts the heating element with the liquid or uses alternative liquid delivery mechanisms that eliminate the need for fibrous materials, thereby preventing fiber fragmentation and inhalation hazards
Solution Approach 2:
The patent employs a disposable heating element or cartridge system where the heating component is replaced frequently. This approach eliminates the need for durable, reusable wicks by designing a system where the entire heating assembly is discarded after a single use, preventing fiber degradation and inhalation risks
2Stability of the object's composition
If porous ceramic is used as the heating body, then temperature stability and safety are improved, but the porosity fluctuates greatly in batch production, resulting in inconsistent vaporization effects
Solution Approach 1:
The patent transitions from using porous ceramic to alternative materials or structures where the key parameter (porosity) can be more precisely controlled. This may involve using materials with different physical properties or designing a structure where porosity is not the primary mechanism for liquid transport, thereby achieving consistent vaporization without batch production variability
Solution Approach 2:
While the patent moves away from traditional porous ceramic, it may still utilize porous materials with differently controlled structures or alternative porous substrates that offer more consistent manufacturing characteristics. The invention reimagines the porous structure to achieve predictable liquid transport and heating performance
3Power
If porous ceramic is used as the heating body, then the heating function is achieved, but the poor liquid-locking ability causes oil leakage
Solution Approach 1:
The patent removes the porous ceramic heating body that causes liquid leakage. By eliminating this component, the system avoids the liquid-locking problems inherent in porous ceramic structures while maintaining heating function through alternative mechanisms that do not rely on porous material retention
Solution Approach 2:
The patent may employ composite material structures that combine different materials with complementary properties. This could involve pairing a non-porous heating element with a separate liquid retention mechanism, or using composite structures that provide both heating capability and effective liquid locking without relying on porous ceramic
4Power
If the surface of porous ceramic is rough and heating film thickness is non-uniform, then the heating function is achieved, but local high temperature and dry burning occur
Solution Approach 1:
The patent applies local quality principles by ensuring uniform heating characteristics across the entire heating surface. This may involve designing a heating element where the heating properties are consistently distributed, or using a structure that promotes even heat distribution, thereby preventing localized overheating and dry burning while maintaining effective heating function
