Solution Overview

Problem

Existing methods for shredding scrap skeletons produced during separating machining of metal sheets are inefficient, often requiring expensive mechanical devices and time-consuming processes, which can delay the machining process.

Innovation Solution

A method involving the creation of an incomplete joint with a breakable residual connection along a separating line on the scrap skeleton, allowing the scrap skeleton parts to be deflected perpendicularly and separated by gravity, eliminating the need for expensive mechanical devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If expensive mechanical devices are used for shredding scrap skeletons, then the shredding capability is improved, but the device complexity and cost increase

Engineering Contradiction:

Improveshredding capabilityVSAvoidmechanical device complexity

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical shredding devices with a gravity-based separation system. An incomplete joint is created along a separating line, allowing scrap skeleton parts to be deflected and separated by gravity without requiring expensive mechanical shredding equipment. This substitution of mechanical systems with gravitational force resolves the contradiction between shredding capability and device complexity.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The scrap skeleton is designed to separate itself through the incomplete joint mechanism. When deflected, the scrap skeleton automatically breaks apart along the predetermined separating line without requiring external mechanical intervention. This self-service approach eliminates the need for complex mechanical shredding devices while maintaining effective separation capability.

Inventive Principle:

Principle #25Self-service

2Ease of manufacture

If mechanical shredding devices are used, then the scrap skeleton can be broken down, but the processing time increases

Engineering Contradiction:

Improveshredding effectivenessVSAvoidshredding processing time

Core Design Contradiction:

Ease of manufactureVSLoss of time

Solution Approach 1:

The incomplete joint is created in advance during the separating machining process, preparing the scrap skeleton for rapid separation. This preliminary action eliminates the need for time-consuming mechanical shredding operations, as the scrap skeleton is already pre-configured to separate along the predetermined line when deflected, significantly reducing processing time.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The scrap skeleton is divided into manageable parts through the incomplete joint created along the separating line. This segmentation allows for easier handling and faster separation compared to attempting to shred the entire skeleton as one piece, reducing the overall processing time while maintaining shredding effectiveness.

Inventive Principle:

Principle #1Segmentation

AI summary

A method for shredding a scrap skeleton produced as a machining product of separating machining of a plate-like workpiece and having a scrap skeleton main plane is provided. The method includes creating an incomplete joint having a course along a separating line running in a longitudinal direction. The scrap skeleton is machined for separation along the separating line. A breakable residual connection arranged along the separating line is established between a first scrap skeleton part and a second scrap skeleton part. The method further includes, after the incomplete joint is created, deflecting the first scrap skeleton part and the second scrap skeleton part relative to one another perpendicularly to the scrap skeleton main plane so that the residual connection between the first scrap skeleton part and the second scrap skeleton part breaks, thereby separating the first scrap skeleton part and the second scrap skeleton part from one another.
