Aerosol Generator Battery Contact Layout for Safe Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inhalation devices, such as e-cigarettes and nebulizers, lack a suitable arrangement for battery replacement, which is essential for consumer protection and environmental sustainability.
Innovation Solution
An aerosol generation system with a housing, accommodating portion, electrical contacts, and a control circuit, where the electrical contacts are positioned further to the opening side than the battery pack, and offset from the load, along with a charging terminal positioned similarly, to facilitate easy and safe battery replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electrical contacts are positioned at the battery pack end, then the battery pack can be easily inserted and removed, but the electrical contacts are exposed to heat from the load and suffer from wear and short-circuiting risks
Solution Approach 1:
The patent repositions the electrical contacts from the battery pack end (longitudinal dimension) to the substrate end (transverse dimension relative to battery insertion). This spatial reconfiguration in another dimension allows the contacts to be electrically connected to the battery while being physically separated from the heat-generating load, resolving the contradiction between ease of battery replacement and electrical contact reliability under thermal stress
2Loss of energy
If the electrical contacts are positioned close to the load, then power transmission efficiency is improved, but the contacts are exposed to high temperature and experience increased wear
Solution Approach 1:
The patent introduces the substrate as an intermediary component between the electrical contacts and the load. The substrate's terminal block serves as a mediation point where electrical connections are made, allowing the contacts to be positioned away from the heat-generating load while maintaining efficient electrical connectivity. This intermediary structure decouples the thermal and electrical pathways, protecting the contacts from thermal damage
3Adaptability or versatility
If the battery pack is made replaceable, then consumer protection and environmental sustainability are improved, but the device complexity increases
Solution Approach 1:
The patent segments the device into distinct functional modules: a replaceable battery pack with its own terminal block, and a substrate with corresponding electrical contacts. This segmentation allows the battery to be independently replaced without affecting other components. The modular design with clear separation of electrical connection points simplifies the overall device structure while enabling battery replaceability
