Interchangeable Cart Mounting for Portable Tool Depth Control

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Portable tools like high-speed saws are difficult to use for cutting materials at a constant depth when held by hand, as operators struggle to maintain control and precision.

Innovation Solution

A cart system with interchangeable mounting assemblies that securely attach and adjust portable tools, allowing for both hand-held and walk-behind operations, featuring a height adjustment mechanism and clamping assembly for secure tool attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If portable tools are held by hand for cutting operations, then operator mobility and flexibility are improved, but cutting precision and depth control deteriorate

Engineering Contradiction:

Improveoperator mobilityVSAvoidcutting depth control

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The system allows dynamic switching between hand-held mode (high mobility, lower precision) and walk-behind cart mode (lower mobility, high precision). The cart system enables the tool to transition from manual operation to cart-mounted operation, providing depth control guidance while maintaining operational flexibility.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The cart system acts as an intermediary between the operator and the portable tool. It provides the guidance and stability needed for precise cutting operations while allowing the operator to remain mobile. The cart serves as a mediating platform that enhances both precision and operator control.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If multiple different portable tools are used, then operational versatility is improved, but device complexity and tool management deteriorate

Engineering Contradiction:

Improvetool compatibilityVSAvoidmounting system complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cart system is designed with universal mounting assemblies that can accommodate multiple types of portable tools through interchangeable mounting mechanisms. The standardized interface allows different tools to be mounted on the same cart system, providing multi-functionality without requiring separate carts for each tool type.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The mounting system is segmented into interchangeable modules that can be easily attached and detached. This modular approach allows different mounting assemblies to be swapped depending on the tool being used, simplifying tool management while maintaining versatility across multiple tool types.

Inventive Principle:

Principle #1Segmentation

AI summary

A system that can include a cart and multiple mounting assemblies, with each one of the multiple mounting assemblies configured to be interchangeably attached to the cart, and with each one of the multiple mounting assemblies configured to receive one of multiple portable tools and secure the one of the multiple portable tools to the cart. The one of the multiple portable tools is different than a second one of the multiple portable tools.
