Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power tools lack an efficient and secure mechanism for connecting battery packs, which can lead to unstable power supply and easy disconnection during use.
Innovation Solution
A power tool assembly with a battery support portion and a pivoting latch mechanism that secures the battery pack along a specific axis, ensuring stable engagement and disengagement of electrical contacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple battery connection mechanism is used, then the device complexity is reduced, but the reliability of power supply and connection stability deteriorates
Solution Approach 1:
The latch mechanism transitions from a static connection to a dynamic one, allowing the battery pack to be easily inserted and removed while maintaining secure engagement during operation. The movable latch member enables the connection state to change between locked and unlocked positions, providing both ease of operation and reliable power supply stability when engaged.
2Reliability
If a secure latching mechanism is implemented, then the reliability of battery connection is improved, but the device complexity increases
Solution Approach 1:
The latch mechanism is designed to automatically engage and lock when the battery pack is inserted, eliminating the need for manual locking operations. The movable latch member is positioned and configured to automatically interact with the battery pack features, providing secure connection without requiring additional user actions or complex control systems.
3Ease of operation
If a latch mechanism with wide movement range is used, then the ease of operation for battery removal is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The latch mechanism utilizes rotational movement about a pivot axis that is transverse to the battery insertion axis, adding a dimensional aspect to the connection mechanism. This rotational degree of freedom allows the latch to engage and disengage the battery pack through pivoting motion, providing ease of operation while the specific geometric configuration of the pivot axis and latch geometry manages the manufacturing precision requirements.

AI summary
A power tool assembly includes a power tool having a battery support portion that defines a battery insertion axis and a battery operatively engageable with the power tool support portion along the battery insertion axis to provide power to the power tool. The power tool assembly also includes a battery latching mechanism having a latch pivotable about a pivot axis transverse to the battery insertion axis and engageable with one of the battery pack or the battery support portion for securing the battery pack to the battery support portion. The battery latching mechanism further includes a handle coupled for pivoting movement with the latch about the pivot axis.
