Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electronic cigarette conductive contact structures are not adequately sealed, allowing tobacco tar to leak into the battery assembly, causing corrosion and short circuits due to the lack of effective sealing between the atomizer and the battery assembly.
Innovation Solution
An installation structure for the conductive contact of an electronic cigarette comprising a receiving groove with a conductive contact that includes a first contact, a second contact, an insulating part, and a sealing part, where the sealing part is designed to elastically abut against both the insulating and first contacts to seal gaps, utilizing sealing rings and a conical spring for enhanced sealing performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple conductive contact structure is used, then the device complexity is reduced, but the sealing performance deteriorates allowing tobacco tar to penetrate into the battery assembly
Solution Approach 1:
The conductive contact structure is divided into multiple functional components: a conductive contact assembly with first and second contacts, an insulating part with upright post and chassis, and a sealing part with first and second sealing rings. This segmentation allows each component to perform its specific function while collectively achieving both electrical connectivity and sealing performance.
Solution Approach 2:
The insulating part acts as an intermediary component between the first and second contacts, providing both electrical insulation and structural support. The sealing part serves as an intermediary element that fills and seals the gap between the conductive contact assembly and the atomizing assembly, preventing tobacco tar penetration while maintaining structural integrity.
2Reliability
If the conductive contact structure is made more complex with additional sealing components, then the sealing performance is improved, but the device complexity increases
Solution Approach 1:
The insulating part and sealing part are integrated into a unified conductive contact assembly that is installed as a single unit in the receiving groove. The insulating part's upright post and chassis are combined with the sealing rings to form a cohesive structure that simultaneously provides insulation, sealing, and mechanical support functions.
Solution Approach 2:
The insulating part serves multiple functions: it provides electrical insulation between contacts, structural support for the sealing rings, and positioning within the receiving groove. The sealing part not only seals gaps but also fills voids and prevents corrosion. This multi-functionality reduces the need for separate dedicated components.
3Reliability
If sealing components are added to prevent tobacco tar leakage, then the reliability is improved, but the manufacturing complexity increases
Solution Approach 1:
The first and second sealing rings are pre-installed onto the insulating part and conductive contacts during the assembly process before final installation into the receiving groove. This preliminary action ensures proper positioning and sealing configuration, simplifying the overall manufacturing process while maintaining reliable sealing performance.
