E-vaping Device Non-Standard Thread Pitch for Precise Mating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional e-vaping devices face challenges in ensuring precise engagement of components due to standard threaded connections, leading to potential misalignment and reduced quality of the vaping experience, as only properly rated and authorized components can mate correctly.
Innovation Solution
The implementation of non-standard or proprietary threaded connections with specific dimensions, such as a 7 mm major diameter and 0.6 mm pitch, ensures precise mating between male and female threads, preventing binding with standard connections 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 is improved, but manufacturing precision deteriorates due to potential misalignment and imprecise engagement of components
Solution Approach 1:
The patent applies parameter changes by modifying the thread pitch from standard values to nonstandard values. Specifically, the male thread connector has a first pitch and the female thread connector has a second pitch that differs from standard pitches, ensuring precise engagement while maintaining ease of manufacture through standardized thread dimensions otherwise
Solution Approach 2:
The patent applies local quality by making the thread pitch nonstandard only in the critical engagement region while keeping other thread parameters (major diameter, minor diameter, pitch diameter) standard. This localized modification ensures precise component engagement without requiring complete deviation from standard thread specifications
2Manufacturing precision
If nonstandard threaded connections are used, then manufacturing precision is improved through precise engagement, but device complexity increases due to proprietary threading requirements
Solution Approach 1:
The patent modifies only the pitch parameter of the threads while keeping other parameters standard, thereby achieving precise engagement without substantially increasing device complexity. The nonstandard pitch prevents binding with standard connections while maintaining compatibility with standardized manufacturing processes
Solution Approach 2:
The patent segments the thread parameters into standard portions (major diameter, minor diameter, pitch diameter) and nonstandard portions (pitch), allowing precise engagement through the nonstandard pitch while maintaining ease of manufacture through standard parameters

AI summary
The e-vaping device includes a first section with a housing, an inner tube within the housing, a reservoir configured to contain a liquid material, a heater and wick in communication with the reservoir and the inner tube and a first threaded connector at an end of the first section. The first threaded connector has first threads with a non-standard pitch. A second section includes a power supply and a second threaded connector at an end of the second section. The second threaded connector has second threads configured to mate with the non-standard pitch of the first threads. Values of nominal dimensions of the first and second threads, other than the non-standard pitch of the first and second threads, are standard nominal thread dimensions.
