Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic cigarette battery compartments with small buttons are uncomfortable to use, prone to damage, and have short service life due to their design, and the large buttons required for portability are difficult to install without increasing the compartment size.
Innovation Solution
A battery compartment design featuring a support with a mounting hole, elastic element, and revolving shaft, along with a connector assembly and wedge blocks, which increases the button's travel distance and stress area, reducing the force required to press the button and enhancing its durability and installation flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If small buttons are used in the battery compartment, then the device size is reduced, but the button is uncomfortable to use, easy to damage, and has short service life
Solution Approach 1:
The button structure is segmented into multiple functional components: a button body for user input, a traveling shaft for mechanical movement, and an elastic element for providing restoring force. This segmentation allows each component to be optimized independently, enabling the button to maintain a compact overall size while providing sufficient travel distance and operational comfort through the extended shaft mechanism.
Solution Approach 2:
The button design extends in the vertical dimension through the traveling shaft that protrudes from the button body. This dimensional extension allows the button to have a compact footprint (planar size) while providing sufficient press travel distance vertically, resolving the contradiction between small device size and comfortable button operation.
2Volume of moving object
If small buttons are used in the battery compartment, then the device size is reduced, but the button is easy to damage and has short service life
Solution Approach 1:
An elastic element (such as a spring or rubber component) is incorporated into the button structure to provide cushioning and shock absorption. This elastic element absorbs impact forces during button pressing, preventing direct transmission of stress to the switch mechanism and reducing the risk of damage, thereby extending button service life while maintaining compact dimensions.
Solution Approach 2:
The button design changes the mechanical parameters by extending the traveling shaft length to increase press travel distance from conventional 0.2-0.3mm to a longer distance. This parameter change distributes the mechanical stress over a longer行程, reducing peak forces on individual components and improving reliability while keeping the overall device size compact.
3Ease of operation
If large buttons are used to improve usability, then the battery compartment size increases, but portability is reduced
Solution Approach 1:
The button design utilizes the vertical dimension by extending the traveling shaft downward from the button body. This allows the button to provide sufficient press travel distance (improving usability) without increasing the horizontal footprint, thereby maintaining a compact battery compartment size that preserves portability.
Solution Approach 2:
The traveling shaft is nested within or integrated with the button body structure, with the shaft extending from the button in a space-efficient manner. This nested arrangement allows the button mechanism to provide extended travel distance without proportionally increasing the overall volume of the battery compartment, resolving the contradiction between usability and portability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design improves the usability and longevity of the button by distributing the stress evenly and reducing the force needed to press it, while allowing for a more compact battery compartment that facilitates portability without increasing size.
Implementation Method 1
