Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing stone cutting devices remove excessive material during the cutting process, resulting in a significant loss of material and a need for more efficient cutting methods.

Innovation Solution

A device featuring a monolithic metallic support bar with a longitudinal channel and fluid ports, coupled with a cutting belt and wear bar, that minimizes material removal by guiding the cutting belt along a precise path, allowing for a narrower cutting width and efficient material retention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a continuous cutting belt is used with a width of no less than 0.535 inches, then the cutting operation can be performed effectively, but the amount of material removed increases significantly

Engineering Contradiction:

Improvecutting operation effectivenessVSAvoidmaterial removed

Core Design Contradiction:

ReliabilityVSLoss of substance

Solution Approach 1:

The patent changes the critical parameter of cutting belt width from the conventional minimum of 0.535 inches to a narrower width of 0.325 inches. This parameter change is made possible by the monolithic metallic support bar with precision longitudinal channel that guides the narrower belt, achieving both effective cutting and reduced material removal.

Inventive Principle:

Principle #35Parameter changes

2Ease of manufacture

If a support frame with multiple pieces welded or secured together is used, then the frame can be constructed with standard manufacturing methods, but the guide assembly complexity increases

Engineering Contradiction:

Improveframe constructionVSAvoidguide assembly structure

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent merges multiple separate frame pieces into a single monolithic metallic support bar. This consolidation eliminates the need for welding or screwing multiple pieces together, simplifying the guide assembly structure while maintaining manufacturing feasibility through single-piece fabrication.

Inventive Principle:

Principle #5Merging (Combining)

3Stability of the object's composition

If a wider cutting path is used to ensure stable cutting, then cutting stability is improved, but the amount of material loss increases

Engineering Contradiction:

Improvecutting path stabilityVSAvoidmaterial removed

Core Design Contradiction:

Stability of the object's compositionVSLoss of substance

Solution Approach 1:

The patent replaces the mechanical stability approach (wider cutting path) with a precision guidance system. The monolithic metallic support bar with a precisely machined longitudinal channel provides mechanical constraints that guide the narrower cutting belt, achieving cutting path stability through precision guidance rather than width.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
