Angled Battery Port for Power Tool Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The location of the battery connection port on power tools often obstructs the user's view of the battery's state of charge and handling, making it inconvenient to operate the tool while assessing the battery status.
Innovation Solution
An angled battery connection port is designed, positioning the second portion closer to the tool end than the first, allowing for improved visibility of the fuel gauge and streamlined operation by reducing interference during use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the battery connection port is positioned in a conventional location on the power tool, then the battery pack can be securely connected to the tool, but the user cannot simultaneously operate the tool and assess the state of charge of the battery pack
Solution Approach 1:
The battery connection port is positioned at an angle relative to the longitudinal axis of the power tool housing, creating a multi-dimensional arrangement. This angular positioning allows the battery pack to be oriented such that its display surface faces a direction accessible to the user during operation, resolving the contradiction between secure connection and visibility of battery status.
2Ease of operation
If the battery connection port is positioned in a conventional location, then the battery pack can be securely mounted, but the battery pack creates an obstacle to proper handling of the power tool
Solution Approach 1:
The battery connection port is positioned asymmetrically at an angle rather than symmetrically along the longitudinal axis. This asymmetric angular positioning allows the battery pack to be mounted in a configuration that minimizes interference with the user's hand grip and tool handling, while maintaining secure electrical and mechanical connection.
3Reliability
If the battery pack is positioned in a conventional location, then electrical connection can be maintained, but the user must manipulate the power tool to view the fuel gauge
Solution Approach 1:
The battery pack is positioned at an angular orientation relative to the tool's longitudinal axis, creating a spatial arrangement where the fuel gauge display surface is oriented toward the user's line of sight during normal operation. This angular positioning in a different dimensional orientation allows simultaneous electrical connection and direct visibility of the fuel gauge without requiring tool manipulation.

AI summary
A power tool includes a housing configured to house a motor. The housing defines a body axis and has a hand grip for a user, wherein the hand grip is positioned between a first end and a second end of the housing. The power tool further includes a tool element positioned at the first end of the housing and a battery connection port adapted to receive a battery pack. The battery connection port defines a removal axis for the battery pack and includes a first portion located at one end of the removal axis and a second portion located at an other end of the removal axis opposite the first portion. The second portion is positioned closer to the tool end than the first portion.
