Solution Overview

Problem

Conventional methods for adjusting the thickness of a laminated core by controlling manufacturing conditions complicate the manufacturing device, making it inflexible and requiring modifications.

Innovation Solution

A method and device that utilize a peeling blade on a substrate member to adjust the thickness of a laminated core by sliding it relative to the laminated core, allowing for easy adjustment without modifying the manufacturing device, using a holding mechanism and sliding mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If conventional measures are taken to adjust thickness by controlling manufacturing conditions, then the thickness of the laminated core can be adjusted, but the manufacturing device becomes complicated and requires modifications

Engineering Contradiction:
Improvethickness of laminated coreVSAvoidmanufacturing device
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The invention separates the thickness adjustment function from the manufacturing process by using a dedicated peeling device that removes individual core sheet materials one by one. This segmentation allows the manufacturing device to remain simple while achieving precise thickness control through the peeling operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention extracts the thickness adjustment function from the manufacturing process and implements it as a separate post-manufacturing operation using a peeling blade. This extraction eliminates the need to modify the manufacturing device while still achieving the desired thickness adjustment.

Inventive Principle:
Principle #2Taking out (Extraction)

2Manufacturing precision

If manufacturing conditions are changed to compensate for sheet thickness variations, then the laminated core thickness falls within acceptable range, but the manufacturing process becomes complicated

Engineering Contradiction:
Improvethickness of laminated coreVSAvoidmanufacturing process
Core Design Contradiction:
Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The peeling device automatically determines how many core sheet materials to remove based on the actual thickness measurement, eliminating the need for complex pre-planned manufacturing condition adjustments. The system serves itself by making real-time decisions about the required peeling amount.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The invention changes the approach from adjusting manufacturing parameters to changing the final product parameter through material removal. Instead of modifying manufacturing conditions, the system directly adjusts the laminated core thickness by peeling off specific numbers of core sheet materials based on measured deviations.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If a general manufacturing device is used, then device adaptability is maintained, but it cannot easily adjust to thickness variations without modification

Engineering Contradiction:
Improvedevice adaptabilityVSAvoidadjustment ease
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The peeling device is designed as a universal post-processing unit that can be applied to various laminated core manufacturing scenarios without requiring modifications to the original manufacturing device. It adds the adaptability function independently while maintaining compatibility with general manufacturing devices.

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

AI summary

The present invention provides a technology capable of easily adjusting the thickness of a laminated core without modifying a device for manufacturing a laminated core itself. The present invention brings a laminated core A and a substrate member 1 including a peeling blade 11 having a protruding height equivalent to one or a plurality of core sheet materials A1 constituting the laminated core A into contact with each other and causes the laminated core A and the substrate member 1 to relatively slide to peel off one or a plurality of core sheet materials A1 from the laminated core A.
