Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the atomizer is fixed to the power supply device, then the connection is stable, but the user cannot adjust the angle of the cigarette holder
Solution Approach 1:
The atomizer is designed to be rotatable relative to the power supply device within the cavity, transforming a static fixed connection into a dynamic adjustable one. This allows the user to freely adjust the angle of the cigarette holder while maintaining a simple connection structure without complex rotating mechanisms
Solution Approach 2:
The connection structure is divided into separate functional components: the power supply device cavity, the atomizer, and the screw sleeve. This segmentation allows independent optimization of each component - the cavity provides stable housing, the atomizer provides adjustability, and the screw sleeve provides simple fastening - resolving the contradiction between stability and adjustability
2Ease of operation
If a rotating connection component is used to allow angle adjustment, then the user can adjust the cigarette holder angle, but the operation becomes complicated and manufacturing cost increases
Solution Approach 1:
The complex rotating connection component is extracted and replaced with a simple screw sleeve fastening mechanism. The adjustability function is achieved through the rotatable arrangement of the atomizer within the cavity rather than through a dedicated rotating mechanism, significantly simplifying both manufacturing and operation
Solution Approach 2:
The screw sleeve uses simple, inexpensive ferromagnetic material that can be easily manufactured and replaced if needed. This replaces expensive, complex rotating connection components with a simple, cost-effective fastening solution that achieves the same functional goal
3Ease of manufacture
If the screw sleeve is made of ferromagnetic material for magnetic adsorption, then the connection is simple and cost-effective, but electrical conduction must be ensured through insulation design
Solution Approach 1:
The screw sleeve has different material properties at different locations: ferromagnetic material for magnetic adsorption, and insulating coating or insulating structure at the conduction head interface. This local differentiation allows the screw sleeve to simultaneously achieve magnetic fastening and reliable electrical conduction without compromising either function
Solution Approach 2:
The conduction head acts as an intermediary between the ferromagnetic screw sleeve and the electrical contact point. It ensures reliable electrical conduction while being insulated from the ferromagnetic material, resolving the conflict between magnetic attraction and electrical insulation requirements
