Movable Power Tool Carriage for Stable Drill Stand Mounting

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing power tool stands, such as those for drills, are cumbersome due to the large and heavy nature of battery-powered drills, making mounting and operation awkward, and hoses for dust and lubrication management interfere with the drill's operation, complicating setup and removal.

Innovation Solution

A power tool stand with a base, projecting frame, and moveable power tool carriage that includes electrical interfaces for connecting tools and batteries, a rack and pinion mechanism for easy movement, and features like wheels, pivotability, and locking mechanisms for stability and ease of use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a drill stand is used to mount a battery-powered drill, 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 stand cumbersome

Engineering Contradiction:

Improvestability of power toolVSAvoidease of mounting and using

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

The power tool carriage is designed as a separate, moveable component that can be easily attached to and removed from the drill stand. This segmentation allows the carriage (which holds the tool and battery) to be handled independently from the heavy stand structure, making mounting and operation easier while maintaining stability when assembled.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The power tool carriage is made moveable along the drill stand rather than being fixed, allowing dynamic adjustment of position. This enables easy loading and unloading of tools and batteries, and allows the carriage to be positioned optimally during use, improving ease of operation while the stand provides stable support.

Inventive Principle:

Principle #15Dynamics

2Reliability

If dust management and lubrication management hoses are attached to the drill on the drill stand, then dust and lubrication management is achieved, but the hoses interfere with the operation of the drill making setup, use and removal awkward and time consuming

Engineering Contradiction:

Improvedust and lubrication managementVSAvoidease of setup, use and removal

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The dust and lubrication management connections are integrated into the power tool carriage structure rather than requiring separate hoses attached to the drill. This extraction of the connection points to the carriage level eliminates interfering hoses while maintaining reliable dust and lubrication management functionality.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The dust management and lubrication management connection points are merged into the power tool carriage assembly, combining multiple functions at a single location. This eliminates the need for separate hose connections to the drill, reducing interference and simplifying setup, use, and removal operations.

Inventive Principle:

Principle #5Merging (Combining)
