Electronic Cigarette Housing Trim Integration via Hot-Melt Bonding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic cigarette assembly structures face issues with precision and tolerance matching, leading to incomplete assembly, deformation, and looseness, which affect structural rigidity, reduce service life, and increase production failure rates.
Innovation Solution
An electronic cigarette assembly structure featuring a casing and bottom cover integrally formed with a decorative groove, where a hot-melt material decorative piece is integrated through a heating process, providing a ring-shaped groove for enhanced structural rigidity and protection, along with a detachable nozzle cover and improved sealing mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If adhesive bonding is used to assemble the shell and bottom cover, then assembly is simplified, but structural rigidity deteriorates and parts deformation occurs
Solution Approach 1:
The patent integrates the decorative piece directly into the bottom cover through injection molding, merging three components (bottom cover, decorative piece, and bonding adhesive) into a single integrated structure. This eliminates the need for separate assembly steps while maintaining structural integrity and rigidity, as the decorative piece becomes an inherent part of the bottom cover rather than a separately bonded component.
2Shape
If decorative pieces are separately bonded to the shell, then aesthetic design is improved, but assembly precision requirements increase and production failure rate increases
Solution Approach 1:
The decorative piece is integrated into the bottom cover through injection molding, combining aesthetic design with manufacturing simplicity. The decorative features are formed directly during the molding process, eliminating the need for separate assembly operations and reducing precision requirements for matching tolerances between separate parts.
Solution Approach 2:
The decorative piece is pre-formed as an integral part of the bottom cover during the injection molding process, before any assembly operations. This preliminary integration ensures that the decorative features are precisely positioned and eliminates the need for subsequent alignment and bonding operations that would require high precision.
3Adaptability or versatility
If multiple separate parts are used for shell and bottom cover assembly, then design flexibility is improved, but the number of assembly steps increases and production efficiency decreases
Solution Approach 1:
The patent combines the bottom cover and decorative piece into a single injection-molded component, reducing the number of parts and assembly steps. This integration maintains design flexibility through the ability to incorporate complex decorative features during molding while significantly improving production efficiency by eliminating separate assembly operations.

AI summary
An electronic cigarette includes a housing, wherein the housing is elongate and has a head end disposed toward the user and a tail end extending away from the user. The housing comprises a bottom cover and a shell section. A battery is retained within the housing. An atomizer tank cartridge fits to the housing. An electrical heating apparatus powered by the battery. A groove is formed between the bottom cover and the shell section. A trim piece is mounted between the bottom cover and shell section. The trim piece is a hot-melt material, and connected to the groove via a heating process. The trim piece passes around an external periphery of the housing. The trim piece is an epoxy resin material. The housing further comprises a removable mouthpiece cover attached at a head end.
