Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If magnet connection method is used to connect atomizer assembly and power assembly, then the connection is simple, but the connection becomes ineffective at high temperature
Solution Approach 1:
The patent replaces the magnetic connection system with a mechanical connection system using a connecting assembly that includes a connecting piece with a connecting end and a limiting end. The connecting piece mechanically engages with limiting grooves on the atomizer assembly and power assembly, providing a temperature-resistant mechanical connection that substitutes the failed magnetic attraction mechanism.
2Ease of manufacture
If rubber component deformation method is used for connection, then the components can be connected, but the structural stability is poor due to abrasion or high temperature causing leakage or contact failure
Solution Approach 1:
The patent replaces the rubber deformation connection system with a rigid mechanical connection system using the connecting assembly. The connecting piece with limiting grooves provides a stable structural connection that resists abrasion and high temperature, eliminating the leakage and contact failure problems associated with rubber component degradation.
Solution Approach 2:
The connecting assembly appears to use composite material construction, combining different materials with complementary properties - the connecting piece likely uses heat-resistant materials for the limiting ends while maintaining structural integrity. This composite approach provides both connection feasibility and high structural stability under harsh conditions.
3Ease of manufacture
If wire connection method is used, then electrical connection can be established, but contact failure is easily caused which greatly reduces service life
Solution Approach 1:
The patent merges the mechanical connection function and electrical connection function into a single integrated connecting assembly. The connecting piece simultaneously provides mechanical support through its limiting ends and electrical connection through integrated conductive elements, eliminating the separate wire connection that was prone to contact failure and reducing overall system complexity.
4Ease of manufacture
If conventional connection methods are used, then assembly can be completed, but the electronic cigarette is susceptible to environmental variation
Solution Approach 1:
The connecting assembly implements local quality by providing specialized connection interfaces at critical locations. The limiting grooves and connecting ends are designed with specific geometric properties tailored to resist particular environmental stresses, while the overall assembly maintains ease of manufacture through modular design that integrates these specialized features into the standard assembly process.
