Battery Pack Mounting Guides for Mixed Interface Sizes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical devices and battery packs are limited by fixed interface sizes, restricting their ability to adapt to different battery pack sizes, which hinders universalization and miniaturization.
Innovation Solution
The electrical device features a battery pack mounting portion with independent first and second guiding portions, allowing it to engage with battery packs of different interface sizes, facilitating universalization and miniaturization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed interface size is used for battery pack mounting, then the structure is simple and easy to manufacture, but the device cannot adapt to battery packs of different sizes
Solution Approach 1:
The battery pack mounting portion is designed with multiple guiding portions (first guiding portions and second guiding portions) that can accommodate different battery pack interface sizes. The guiding portions are arranged to provide guidance for both first battery packs and second battery packs with different dimensions, enabling a single mounting structure to serve multiple battery pack types.
Solution Approach 2:
The guiding portions are segmented into distinct first guiding portions and second guiding portions, each optimized for specific battery pack sizes. These segmented guiding structures are independently arranged to provide size-specific guidance while being integrated into a unified mounting portion, allowing the device to adapt to different battery pack dimensions without requiring completely separate mounting structures.
2Adaptability or versatility
If two interfaces with different sizes are separately arranged in different regions, then different battery packs can be accommodated, but the device size increases and miniaturization is hindered
Solution Approach 1:
Multiple guiding portions for different battery pack sizes are merged into a single battery pack mounting portion. The first guiding portions and second guiding portions are integrated within the same mounting structure, allowing the device to accommodate different battery pack types without requiring separate mounting regions, thereby reducing overall device volume.
Solution Approach 2:
The second guiding portions are arranged within the spatial envelope defined by the first guiding portions, creating a nested configuration. This nesting allows smaller battery pack interfaces to be accommodated within the same mounting region as larger interfaces, maximizing space utilization and preventing device enlargement.

AI summary
An electrical device including: a device housing; and a battery pack mounting portion arranged on the device housing and configured to detachably engage with a first battery pack or a second battery pack. The battery pack mounting portion includes a pair of first guiding portions and a pair of second guiding portions. The first guiding portions are configured to guide the first battery pack to engage with the electrical device in an engaging direction. The second guiding portions are configured to guide the second battery pack to engage with the electrical device in the engaging direction. The first guiding portions and the second guiding portions are independent of each other. In a width direction perpendicular to the engaging direction, the pair of first guiding portions are located on two sides of the pair of second guiding portions.
