Battery Pack Aperture Layout for Balanced Power Tool Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Battery-powered tools face issues with battery pack exposure to impacts, leading to damage or disconnection, and unbalanced ergonomics due to varying battery pack sizes, which affect user comfort and tool stability.
Innovation Solution
A battery-powered tool design featuring a tool body with a through aperture that surrounds the battery pack, providing protection and allowing for easy access, with a locking mechanism and connectors for secure power transfer, and adjustable protrusion to maintain balance across different battery pack sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the battery pack is mounted fully exposed underneath the tool body, then it is easily accessible for removal, but it is exposed to impacts that may cause damage or disconnection
Solution Approach 1:
The battery pack is nested within the tool body through a through-aperture, allowing the tool body to surround and protect the battery pack while maintaining accessibility. The battery pack can be partially inserted into the tool body, combining protection with ease of removal.
2Object-affected harmful factors
If the battery pack is mounted inside the tool body, then it is protected from impacts, but it becomes inaccessible and requires much effort to remove
Solution Approach 1:
The tool body is segmented with a through-aperture that allows the battery pack to be partially inserted and partially accessible. This segmentation enables the battery pack to be protected while maintaining easy accessibility for removal and installation.
3Use of energy by moving object
If a larger battery pack is used to increase power, then the power tool gains more energy, but the center of gravity becomes unbalanced affecting ergonomics
Solution Approach 1:
The through-aperture is arranged perpendicular to the longitudinal direction of the tool, allowing the battery pack to be positioned in a transverse orientation. This dimensional change enables better weight distribution and balance while accommodating larger battery packs for increased energy capacity.

AI summary
The present disclosure relates to a battery powered tool (1) extending in a longitudinal direction (Z), comprising a tool body (10) and a battery pack (20), which battery pack is arranged on the tool body and adapted to power the tool. The tool body is provided with a through aperture adapted to receive the battery pack, such that the tool body at least partly surrounds the battery pack.
