Aerosol Heater Mount With Hook Engagement for Easy Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol generating devices face challenges with heater attachment/detachment, cleaning, prevention of separation during stick insertion, rotation, extended heater replacement, taste alteration, and overheating.
Innovation Solution
The device includes a body with a first insertion space, a pipe with a hook at its lower end, and a mount with an engaging portion that covers the lower opening, allowing easy heater attachment/detachment and preventing rotation, while facilitating cleaning and extending heater replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the heater is firmly fixed in the aerosol generating device, then the heater remains stable during operation, but the heater becomes difficult to replace and clean
Solution Approach 1:
The device is divided into separable components: the heater assembly (including heater and mount) can be detached from the body as a unit. The mount is further segmented with engaging portions that can be separated from the insertion space, allowing the heater to be removed without dismantling the entire device.
Solution Approach 2:
The engaging portions are designed to transition between engaged and disengaged states dynamically. During normal operation, the engaging portions maintain the heater assembly in a stable engaged state. When replacement is needed, the engaging portions can be easily disengaged to allow heater removal.
2Reliability
If the heater is securely attached to prevent separation, then the heater remains in position during stick insertion, but the heater becomes difficult to detach for replacement
Solution Approach 1:
The mounting structure is segmented into the mount with engaging portions and the insertion space with corresponding engagement features. This segmentation allows the heater assembly to be securely attached during operation while enabling easy separation when needed for replacement.
3Reliability
If the heater is fixed in a specific orientation, then the heater maintains proper positioning, but the heater may rotate during stick insertion causing taste changes
Solution Approach 1:
The engaging portions and corresponding engagement features in the insertion space are designed with asymmetric geometries. This asymmetry ensures that the heater assembly can only be attached in the correct orientation, preventing rotation during stick insertion that would alter the taste.
4Ease of operation
If the heater is easily removable for cleaning, then the heater can be frequently replaced and cleaned, but the heater may become loose or separated during operation
Solution Approach 1:
The engaging portions are designed to provide dynamic attachment characteristics: during normal operation, they maintain strong engagement to prevent heater loosening or separation. When replacement is needed, the same engaging portions allow easy detachment without requiring excessive force or complex procedures.
