E-Vaping Device Proprietary Threading for Component Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
E-vaping devices face challenges in ensuring precise and proprietary engagement of e-vaping components, leading to potential contamination and reduced quality due to standard threaded connections, which can be compromised by non-standard pitches.
Innovation Solution
The implementation of non-standard threaded connections with specific dimensions, such as a major diameter of 7.00 mm and a non-standard pitch of 0.6 mm, ensures proprietary engagement, preventing standard connections from mating and ensuring only authorized components are used, thus maintaining high quality and preventing cross-contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If standard threaded connections are used, then ease of manufacture and assembly are improved, but component compatibility and quality control deteriorate due to potential contamination from non-standard pitches
Solution Approach 1:
The patent applies parameter changes by modifying the thread pitch from a standard value to a non-standard proprietary value (e.g., changing from standard ISO pitch to a specific non-standard pitch). This allows the connection to maintain standard thread geometry and manufacturing processes while ensuring only authorized components with matching proprietary pitch can engage, thus preventing contamination and maintaining quality control.
2Reliability
If proprietary threaded connections with non-standard pitch are used, then component compatibility and quality control are improved, but ease of manufacture and assembly deteriorate
Solution Approach 1:
The patent changes the thread pitch parameter to a proprietary non-standard value while keeping all other thread parameters (major diameter, minor diameter, thread angle, etc.) consistent with standard threads. This approach maintains ease of manufacture using standard threading equipment and procedures while achieving the goal of preventing incompatible components from being assembled.
3Ease of operation
If standard threaded connections are used, then ease of operation is improved, but prevention of cross-contamination deteriorates
Solution Approach 1:
The patent modifies the thread pitch parameter to a proprietary non-standard value, which maintains the simplicity of the threading operation and assembly process while preventing cross-contamination. Only components with the matching proprietary pitch can be assembled, ensuring that unauthorized or incompatible components cannot contaminate the system.
4Object-affected harmful factors
If non-standard pitch threads are used, then prevention of cross-contamination is improved, but ease of operation deteriorates
Solution Approach 1:
The patent changes the thread pitch to a proprietary non-standard value, which prevents cross-contamination by ensuring only authorized components with matching pitch can engage. The operation remains simple because the threading geometry and assembly process are unchanged, only the pitch parameter is modified to provide the protective function.

AI summary
An e-vaping device includes a battery section, an e-vaping tank capable of holding a liquid material, and an adapter connecting the battery section to the e-vaping tank. The adapter includes a heater capable of vaporizing the liquid material, and a wick capable of drawing the liquid material from the e-vaping tank to the heater. The adapter is connected to the e-vaping tank and the power source section via threaded connections. The threaded connections between the adapter and the battery section have threads with a non-standard pitch.
