Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If magnetic attraction method is used to fasten the atomizing device, then the atomizing device can be securely attached, but the cost increases due to matching magnetic force requirements
Solution Approach 1:
The patent replaces the magnetic attraction method with a mechanical buckle system. The elastic limit stop with buckle structure provides secure attachment through mechanical interlocking rather than magnetic force, eliminating the need for expensive magnetic components while maintaining reliable connection between the atomizing device and power supply unit.
Solution Approach 2:
The patent uses simple elastic material for the limit stop instead of expensive magnetic components. The elastic buckle is a cost-effective mechanical element that provides sufficient attachment reliability without the high manufacturing costs associated with precision-matched magnetic systems.
2Device complexity
If interference fit method is used to fasten the atomizing device, then the structure is simple, but the interference degree is difficult to control resulting in loose or tight attachment
Solution Approach 1:
The patent introduces an elastic limit stop that can dynamically adjust its state between locked and unlocked positions. The elastic material allows the buckle to flex and adapt to slight variations in assembly while maintaining a consistent, reliable attachment force, eliminating the control difficulties of interference fits.
Solution Approach 2:
The elastic limit stop acts as an intermediary element between the atomizing device and power supply unit. This intermediate component provides a controlled mechanical interface that ensures reliable attachment without requiring precise control of interference degree, as the elastic material compensates for dimensional variations.
3Reliability
If interference fit is too tight, then the atomizing device is securely attached, but it becomes difficult to remove
Solution Approach 1:
The elastic limit stop provides a dynamic locking mechanism that is tight during normal use but can be easily released. When the user pushes the limit stop, the elastic material deforms to release the buckle from the groove, allowing easy removal while maintaining secure attachment during operation.
Solution Approach 2:
The elastic buckle system is designed to be self-locking during normal operation but self-releasing when actuated. The elastic material naturally maintains the locked position for secure attachment, and the same elastic property allows easy release when force is applied to the limit stop, providing both security and ease of removal.
4Ease of operation
If interference fit is too loose, then the atomizing device is easy to remove, but it may fall out during use
Solution Approach 1:
The elastic limit stop creates a dynamic attachment system that adapts to usage conditions. The elastic material provides sufficient locking force to prevent accidental detachment during normal use, while allowing easy release when the user intentionally actuates the limit stop, ensuring both security and ease of operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The elastic limit stop ensures a reliable and user-friendly connection that prevents the atomizing device from falling out or being difficult to remove, enhancing the overall usability and stability of the electronic cigarette.
Implementation Method 1
The power supply unit is provided with an elastic limit stop; the elastic limit stop is partly protruding in the installation slot, and protruded part can slide relatively along the direction perpendicular to the installation direction of the atomizing device. When the atomizing device is installed in the installation slot, the elastic limit stop will be buckled on the atomizing device
Implementation Method 2
the limit stop body is provided with a rotating shaft. Rotating shaft holes are provided on a second side wall and a third side wall that opposite to the accommodation slot; either end of the rotating shaft passes through corresponding rotating shaft hole respectively; and with the cooperation between the rotating shaft and rotating shaft hole, the limit stop body will rotate in the accommodation slot under external force
