Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aerosol generating devices, such as e-cigarettes, face challenges in efficient and versatile charging solutions, particularly in accommodating different orientations and enabling data transmission during charging.
Innovation Solution
The device incorporates at least two contact charging pads on each side, allowing for charging in various orientations and data transmission via a data over power protocol, with the pads arranged in common planes to facilitate contact with a charging mat, enabling flexible charging and data exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single contact charging pad is used on one side of the device, then the device structure is simple, but the device can only be charged in one orientation and data transmission is not enabled
Solution Approach 1:
The charging pad is divided into multiple contact pads (first contact charging pad and second contact charging pad) positioned at different locations on the device housing. Each contact pad can independently establish electrical connection with corresponding charging points on a charging mat, enabling the device to be charged in multiple orientations while maintaining a relatively simple overall structure
Solution Approach 2:
The contact pads serve dual functions: they enable charging in various orientations and simultaneously provide data transmission capability through the same physical interface. This multi-functionality resolves the contradiction by making the charging system versatile without proportionally increasing complexity
2Reliability
If contact charging pads are arranged in common planes to facilitate contact with charging mat, then charging contact is improved, but device complexity increases
Solution Approach 1:
The contact pads are arranged in common planes (first common plane and second common plane) such that all contact points lie at the same electrical potential level relative to the charging mat. This arrangement ensures reliable electrical contact regardless of the device's orientation on the charging mat, improving charging reliability without requiring complex positioning mechanisms
