Solution Overview

Problem

Conventional nick breaking devices for plate-shaped elements are complex to control and require adjustments based on the length and form of the nick, leading to reduced productivity.

Innovation Solution

A nick breaking device with a conveyor and pressing rollers that form a continuous wave shape, allowing for adjustable positioning and resilient force application to break nicks regardless of their location and form, using a carrier support system for height and location adjustments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a parallel shaft with a tool support part is used to break nicks by applying shear force, then the nick can be broken, but the device structure becomes complex and control becomes difficult due to the need to adjust blank length, transfer speed, and rotational speed

Engineering Contradiction:
Improvenick breaking capabilityVSAvoiddevice structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The invention extracts the nick breaking function from the complex parallel shaft mechanism and implements it through a simple pressing roller that applies direct downward pressure on the nick. This removes the need for synchronized rotation and complex tool support structures, significantly simplifying the device while maintaining effective nick breaking capability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of using a rotating tool support part that applies shear force horizontally, the invention inverts the approach by using a pressing roller that applies compressive force vertically downward on the nick. This inversion of the force application method simplifies the mechanism while achieving the same nick breaking effect.

Inventive Principle:
Principle #13The other way round (Inversion)

2Reliability

If the tool support part is coupled to a parallel shaft to be rotatable, then the nick can be broken through shear force, but the control becomes complex requiring adjustment of blank length, transfer speed, and rotational speed

Engineering Contradiction:
Improvenick breaking effectivenessVSAvoidcontrol simplicity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The pressing roller is designed to automatically follow the contour of the plate-shaped element as it moves along the conveyor. The roller passively adapts to different blank lengths and nick positions without requiring active control adjustments, making the system self-adjusting and eliminating complex speed synchronization requirements.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The invention replaces the complex mechanical synchronization system (parallel shaft with rotational tool support) with a simpler mechanical system where the pressing roller directly contacts and follows the plate-shaped element on the conveyor, eliminating the need for coordinated rotational control.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If the tool support part is replaced according to the length of the blank and form of the nick, then different nick configurations can be broken, but productivity deteriorates due to replacement time

Engineering Contradiction:
Improveadaptability to different nick formsVSAvoidproduction efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The pressing roller is designed as a universal component that can handle various nick forms, lengths, and positions on different plate-shaped elements. Instead of requiring multiple specialized tool support parts, a single pressing roller design serves all nick breaking needs, eliminating replacement time and improving productivity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The pressing roller is designed to dynamically adapt to different nick configurations through its contact-based operation on the moving plate-shaped element. The roller's position and pressure automatically adjust to the specific nick location and form, providing versatile nick breaking capability without requiring physical replacement of components.

Inventive Principle:
Principle #15Dynamics

4Reliability

If the length and transfer speed of the blank are adjusted to match the rotational speed of the parallel shaft, then the nick can be broken, but the overall structure becomes complex

Engineering Contradiction:
Improvenick breaking precisionVSAvoidsynchronization mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The pressing roller system is self-synchronized with the conveyor movement through direct contact with the plate-shaped element. The roller automatically adapts to the element's speed and position without requiring external synchronization mechanisms, eliminating the need for complex speed matching between multiple components.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The invention removes the parallel shaft and its rotational synchronization mechanism entirely, replacing it with a pressing roller that operates independently on the conveyor. This extraction of the synchronization requirement simplifies the overall device structure while maintaining reliable nick breaking precision.

Inventive Principle:
Principle #2Taking out (Extraction)
