Battery-Offloaded Power Tool Stand for Stable Drill Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power tool stands, such as those for drills, are cumbersome due to the weight and size of battery-powered drills, making mounting and operation awkward, and hoses for dust and lubrication management can interfere with operation, while vacuum control systems may malfunction due to vibrations.
Innovation Solution
A power tool stand with a moveable carriage that accommodates removable power tools and batteries, featuring a rack and pinion mechanism, and a system for connecting multiple batteries in series or parallel, along with integrated dust and water management, and a vacuum seal control system to prevent misoperation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a battery-powered drill is mounted on a drill stand, then the stability of the power tool during use is improved, but the drill power tool is very large and heavy making mounting and using it on the drill stand cumbersome
Solution Approach 1:
The power tool system is segmented into separate components: the drill body and the battery are separated. The battery is mounted on the drill stand rather than on the drill itself, allowing the drill to be lighter and easier to handle while maintaining stability through the stand's support structure.
Solution Approach 2:
An interface mechanism serves as an intermediary between the drill and the drill stand. This interface includes electrical contacts and mechanical mounting features that allow the drill to be easily attached and detached while providing stable support and power connection during operation.
2Reliability
If dust management and lubrication management hoses are attached to the drill, then dust and lubrication are managed, but these hoses interfere with the operation of the drill when installed on the drill stand
Solution Approach 1:
The hoses are extracted from the drill body and repositioned to connect to the drill stand. The dust extraction hose and lubrication hose are routed through the stand's structure rather than being attached to the drill, eliminating interference with drill operation while maintaining their functional effectiveness.
3Stability of the object's composition
If the base of the drill stand is weighted down, then the drill stand stability is improved to prevent toppling, but the overall weight and complexity of the system increases
Solution Approach 1:
The drill stand incorporates a weighted base that acts as a counterweight to prevent toppling during vertical operation. The base contains dense material or additional mass strategically positioned to lower the center of gravity and provide stabilizing moment forces that counteract the toppling tendency of the mounted drill.
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
Facilitates easy and stable mounting of power tools, manages dust and lubrication efficiently, and ensures accurate vacuum control, enhancing user convenience and operational precision.
Implementation Method 1
A problem with this is that a control unit detects signals from an accelerometer to detect vibrations in the drill stand to infer a poor seal against the workpiece surface
Implementation Method 2
a control unit detects signals from an accelerometer to detect vibrations in the drill stand
