Cross-Angled Battery Pack Charger Layout for Compact Multi-Pack Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing charging apparatuses for rechargeable battery packs are often bulky and inefficient in accommodating multiple battery packs due to parallel or coaxial connections, limiting their compactness and functionality.
Innovation Solution
A charging apparatus design with intersecting connection directions for two rechargeable battery packs, allowing for a compact layout by ensuring that only one pack can be connected at a time, and featuring separate electrical interfaces with optimized spacing and varying widths to enhance compatibility and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If parallel or coaxial connections are used for multiple battery packs, then the charging apparatus can accommodate multiple battery packs, but the device becomes bulky and loses compactness
Solution Approach 1:
The patent transitions from parallel or coaxial connection arrangements to intersecting connection directions that cross each other at angles. This dimensional reconfiguration allows multiple battery packs to be connected in a more space-efficient manner, reducing the overall volume of the charging apparatus while maintaining the capability to charge multiple packs simultaneously.
2Volume of moving object
If the charging apparatus is designed to be compact, then space utilization is improved, but the ability to accommodate multiple battery packs with separate interfaces is limited
Solution Approach 1:
The charging apparatus is designed with multiple rechargeable battery interfaces (first and second interfaces) that can accommodate different types of battery packs. Each interface is configured with specific connection directions that intersect, allowing the single charging apparatus to serve multiple battery pack types and configurations without requiring separate charging devices for each.
3Volume of moving object
If connection directions are arranged to intersect and cross, then compactness is achieved, but the complexity of ensuring proper spacing and compatibility increases
Solution Approach 1:
The patent employs asymmetric arrangement of the connection directions for the first and second rechargeable battery interfaces. The directions are configured to cross at specific angles rather than being symmetric or parallel, which optimizes space utilization while the asymmetric design inherently provides distinct connection pathways that reduce interference between interfaces.
Solution Approach 2:
Each rechargeable battery interface is designed with specific local characteristics including particular connection directions, spacing requirements, and geometric configurations. The first interface has different connection direction requirements than the second interface, allowing each to be optimized for its specific function while maintaining overall compactness through the intersecting arrangement.

AI summary
The disclosure relates to a charging apparatus for a rechargeable battery pack, having a housing, having at least one first rechargeable battery interface that is designed so as to releasably connect the charging apparatus to a first rechargeable battery pack along a first connection direction, having a second rechargeable battery interface that is designed so as to releasably connect the charging apparatus to a second rechargeable battery pack along a second connection direction, wherein the connection directions intersect the rechargeable battery pack in the state connected to the charging apparatus. It is proposed that the first connection direction and the second connection direction are arranged crossing each other.
