Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional cartomizer design with separate electrical connection components is used, then reliable electrical connection is achieved, but device complexity and material waste increase
Solution Approach 1:
The patent combines the electrical connection function directly into the cartomizer body by creating through-holes that receive power-supply pins from the aerosol-generating device. This eliminates the need for separate electrical connection components within the cartomizer, reducing overall device complexity while maintaining reliable electrical connection between the power source and vaporizer.
Solution Approach 2:
The cartomizer body is designed to serve multiple functions: it houses the reservoir, vaporizer, and simultaneously provides the electrical connection interface through integrated through-holes. This multi-functional design reduces the number of separate components needed while ensuring reliable power delivery to the vaporizer.
2Reliability
If traditional cartomizer design with multiple components is used, then functional requirements are met, but material waste increases due to disposal
Solution Approach 1:
By integrating the electrical connection components directly into the cartomizer body structure, the patent reduces the total number of separate parts. This streamlined design makes the cartomizer more suitable for recycling or disposal without requiring separation of multiple components, thereby reducing material waste while maintaining full aerosol generation functionality.
Solution Approach 2:
The simplified single-integration design facilitates easier recycling or recovery of materials from disposed cartomizers. With fewer separate components and connections, the entire cartomizer can be more efficiently processed for material recovery or environmentally friendly disposal, addressing the issue of material waste from frequent cartomizer replacement.
3Loss of substance
If simplified cartomizer design with through-holes is used, then material waste is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The through-holes are designed with specific local characteristics - precise sizing and positioning at the interface between the cartomizer body and aerosol-generating device. This localized precision ensures proper reception of power-supply pins while the rest of the cartomizer structure can be manufactured with standard tolerances, balancing manufacturing feasibility with functional requirements.
