Battery-Aligned Percussion Tool Layout for Better Maneuverability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing percussion tools, such as breakers or demolition hammers, are often heavy and cumbersome, making them difficult to maneuver and handle, especially when used in horizontal orientations or for extended periods.
Innovation Solution
The design of a lightweight percussion tool with a removable battery pack and optional remote power unit, along with various configurations of battery and striker axes, allows for a balanced and compact tool that can be easily handled and operated in different orientations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional percussion tools are designed with heavy components for durability and power, then the tool achieves sufficient strength and reliability, but the tool becomes heavy and cumbersome, making it difficult to maneuver and handle
Solution Approach 1:
The tool is divided into modular components including a handle assembly, motor housing, and removable battery pack. This segmentation allows each component to be optimized independently for strength-to-weight ratio, reducing overall tool weight while maintaining structural integrity where needed.
Solution Approach 2:
The tool employs dynamic balance through strategic placement of counterweights and optimization of the center of gravity position. The balanced design allows the tool to be easily maneuvered in various orientations (horizontal, vertical, angled) without requiring excessive operator strength, effectively reducing the perceived weight during operation.
2Duration of action of moving object
If the tool is designed for extended operation periods, then the tool achieves sufficient power and duration of action, but the tool becomes more cumbersome and requires additional assistance
Solution Approach 1:
The tool features a dynamically balanced design with the center of gravity positioned to optimize handling comfort during extended operation. The balanced configuration reduces fatigue and allows single-operator use even during prolonged periods, eliminating the need for additional assistance.
Solution Approach 2:
The tool is designed with universal power source compatibility, accepting various battery pack configurations (different voltages, capacities, and orientations). This multi-functionality allows users to select battery configurations that optimize both operation duration and handling comfort for different application scenarios.
3Ease of operation
If the battery pack is positioned to achieve parallel alignment with the striker axis for balanced design, then the tool achieves improved maneuverability, but the power delivery configuration becomes more complex
Solution Approach 1:
The battery receptacle is designed with universal geometry that accommodates multiple battery pack orientations (parallel, perpendicular, and oblique angles relative to the striker axis). This universal design allows the same receptacle structure to support different power configurations without increasing device complexity, enabling users to optimize for either maneuverability or power delivery based on application needs.

AI summary
A percussion tool includes a housing having a top end, a bottom end, a front end, and a rear end. The housing defines a barrel portion, a handle portion opposite the barrel portion, and a motor housing portion between the barrel portion and the handle portion. The percussion tool also includes an electric motor positioned within the motor housing portion and a percussion mechanism driven by the motor and including a striker supported for reciprocation in the housing. The striker defines a striker axis in a reciprocating direction. The percussion tool further includes a battery receptacle supported by the housing and a battery pack removably coupled to the battery receptacle for providing power to the motor. The battery pack and the battery receptacle define a battery axis extending longitudinally through the battery pack and battery receptacle. The striker axis and the battery axis are parallel.
