Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing crushing tools lack efficient repair options and secure attachment methods, leading to difficulties in maintaining tool integrity and adaptability for different material sizes and requirements.

Innovation Solution

The crushing tool is designed with interchangeable, brazed partial breaking tools made of hard metal, arranged in multiple rows with varying sizes and pitches, allowing for easy replacement and optimal fixation, enabling adaptation to different cutting or crushing needs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of repair

If the crushing tool is divided into multiple individual parts, then ease of repair and replacement is improved, but device complexity increases

Engineering Contradiction:

Improveease of repairVSAvoiddevice complexity

Core Design Contradiction:

Ease of repairVSDevice complexity

Solution Approach 1:

The crushing tool is divided into multiple individual partial crushing tools (3, 4) that can be independently replaced. This segmentation allows only damaged portions to be replaced rather than the entire tool, significantly improving ease of repair while the modular design with standardized carrier part connections keeps the overall system manageable

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If multiple rows of partial crushing tools with different sizes and pitches are used, then adaptability to different material sizes is improved, but device complexity increases

Engineering Contradiction:

ImproveadaptabilityVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Different rows of partial crushing tools have different sizes, pitches, and spatial configurations optimized for specific crushing requirements. This local quality variation allows the tool to adapt to different material sizes and crushing needs, while each row remains a standardized module that can be independently configured

Inventive Principle:

Principle #3Local quality

3Strength

If partial crushing tools are brazed to the carrier part, then strength and fixation are improved, but manufacturing complexity increases

Engineering Contradiction:

ImprovestrengthVSAvoidease of manufacture

Core Design Contradiction:

StrengthVSEase of manufacture

Solution Approach 1:

The mechanical connection between partial crushing tools and the carrier part is replaced with brazing, a thermal joining process. This substitution provides superior strength and fixation compared to mechanical fasteners, while the standardized brazing procedure simplifies the manufacturing process despite the added thermal processing step

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
