Solution Overview
Problem
Existing handheld impact tools have fixed mass and geometry, limiting their versatility and inability to effectively increase impact force using ballast for specific applications.
Innovation Solution
A handheld impact tool with a handle and a hollow container that can be filled with media such as liquids or granular solids, allowing the tool to render forces greater than human hand acceleration and weight, with adjustable configurations for point or distributed forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed mass impact tool is used, then the structure is simple, but the versatility and impact force are limited
Solution Approach 1:
The impact tool is divided into a handle and a separate hollow container that can be filled with different media. This segmentation allows the container to be detached, filled, and refilled with various materials (water, sand, gravel, etc.) to adjust the impact force and mass, thereby increasing versatility without permanently complicating the overall structure.
Solution Approach 2:
The tool transitions from a fixed mass design to a dynamic mass adjustment system. The hollow container enables the user to dynamically change the mass and center of gravity by filling with different media volumes and types, allowing adaptation to different impact requirements while maintaining a relatively simple base structure.
2Object-generated harmful factors
If compressible fluids like air are used to generate impact force, then the tool can operate without heavy ballast, but it creates great vibration and requires a compressor
Solution Approach 1:
The invention uses inexpensive, readily available non-compressible media such as water, sand, gravel, or other granular materials instead of requiring expensive compressible fluid systems. These materials are simply poured into the hollow container, providing immediate impact force without vibration issues, and can be easily replaced or adjusted as needed.
3Force
If ballast is added to increase impact force, then the impact capability improves, but the tool becomes harder to lift and maneuver
Solution Approach 1:
The hollow container design enables dynamic adjustment of mass. Users can fill the container with media to increase impact force when needed, and empty or partially fill it when maneuverability is prioritized. This dynamic control allows optimization of the trade-off between impact force and ease of handling based on specific task requirements.
Solution Approach 2:
The tool allows changing the mass parameter by varying the volume and density of media in the hollow container. Users can select different media types (water for light weight, sand or gravel for heavier impact) and adjust the fill level to achieve the desired balance between impact force and maneuverability for different application scenarios.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The tool provides enhanced impact force capabilities, allowing for greater versatility and predictable force delivery, reducing vibration issues associated with compressible fluids and enabling precise force application.
Implementation Method 1
a gravitational force, and the weight of the impact tool
Implementation Method 2
the force created by acceleration of the human hands in the impact direction
Data Source
AI summary
An impact tool is configured to render a force to a desired area. The impact tool includes a handle configured to be manipulated by human hands. A container has a handle tube that is configured to accommodate the handle and the container is hollow. Media is inserted into the container which increases the force rendered by the impact tool. Lifting the impact tool in a lift direction and rapidly lowering the handle in an impact direction that renders the force in the desired area greater than just the force created by acceleration of the human hands in the impact direction, a gravitational force, and the weight of the impact tool.
