Solution Overview

Problem

Existing power tool stands, such as those for drills, are cumbersome due to the large and heavy nature of the tools, making mounting and usage challenging, and are further complicated by dust management and lubrication hoses that interfere with operation.

Innovation Solution

A power tool stand with a base, a projecting frame, and a moveable power tool carriage that includes electrical interfaces for connecting removable power tools and batteries, along with optional features like a rack and pinion mechanism, handle, and illumination devices, to improve stability and ease of use by distributing weight and reducing hose interference.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a drill power tool stand is designed to mount a large and heavy drill power tool, then the stability of the power tool during use is improved, but the base of the drill power tool stand becomes cumbersome and may need to be weighted down to prevent toppling

Engineering Contradiction:
Improvestability of power tool during useVSAvoidcumbersomeness of drill power tool stand
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The power tool stand is divided into separate functional components: a base, a projecting frame, and a moveably mounted power tool carriage. This segmentation allows each component to be optimized independently, reducing overall complexity while maintaining stability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The power tool carriage is made moveable on the projecting frame, allowing dynamic adjustment of the power tool position. This enables the system to adapt to different tool weights and sizes without requiring a completely redesigned heavy base structure.

Inventive Principle:
Principle #15Dynamics

2Reliability

If dust management and lubrication management hoses are attached to the drill power tool on the drill stand, then dust and lubrication management is improved, but the hoses interfere with the operation of the drill

Engineering Contradiction:
Improvedust and lubrication managementVSAvoidoperation of drill
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The hoses are extracted from the drill power tool itself and repositioned to connect to the power tool stand structure. This separates the dust and lubrication management function from the drill operation, eliminating interference while maintaining reliability.

Inventive Principle:
Principle #2Taking out (Extraction)

3Manufacturing precision

If the drill power tool is mounted on the drill stand, then precision during operation is improved, but setup and removal of the drill on the drill stand becomes awkward and time consuming

Engineering Contradiction:
Improveprecision during operationVSAvoidsetup and removal time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The power tool carriage is designed to be moveable on the projecting frame, enabling quick and easy mounting and removal of the power tool. This dynamic design maintains precision during operation while dramatically reducing setup and removal time.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The power tool carriage is pre-positioned on the projecting frame at an accessible location, allowing the power tool to be quickly mounted and removed without complex setup procedures. The preliminary positioning of the carriage facilitates rapid tool changes.

Inventive Principle:
Principle #10Preliminary action
