Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If core strips are integrated within a laminating barrel by a heater and move downwards, then adhesion fixing method reduces manufacturing costs and corresponds to thickness reduction in steel sheet, but core strips fall to the bottom of the laminating barrel due to gravity causing damage and misalignment
Solution Approach 1:
The patent introduces a support mechanism that provides upward support force to counteract the gravitational force acting on the laminated core member. The support surface is positioned to receive the laminated core member as it exits the heater, preventing it from falling downward due to gravity. This resolves the contradiction by maintaining the low-cost adhesion fixing method while eliminating the alignment precision problems caused by gravitational dropping.
2Ease of manufacture
If core strips pass through heater and peripheral parts, then adhesion fixing method is implemented, but thermal deformation and damage occur leading to misalignment and quality issues
Solution Approach 1:
The patent extracts the laminated core member from the thermal environment immediately after adhesion is achieved. The support mechanism is positioned right at the exit of the heater, allowing the laminated core member to be supported and extracted from the high-temperature zone before significant thermal deformation can occur. This separates the adhesion process (requiring heat) from the support process (avoiding heat), resolving the contradiction between implementing adhesion fixing and preventing thermal deformation.
3Productivity
If adhesive is applied by nozzle, then adhesive laminated core manufacturing is achieved, but adhesive leakage and pollution occur causing clogging and quality defects
Solution Approach 1:
The patent introduces a support surface as an intermediary element between the adhesive application process and the final product. This support surface provides a controlled environment for adhesive application, preventing leakage and pollution by containing the adhesive within the intended application area. The intermediary support structure ensures reliable, precise adhesive application while maintaining manufacturing efficiency.

AI summary
Disclosed herein is a bonded-type laminated core member manufacturing apparatus including an adhesive application unit to apply an adhesive to a material being continuously transferred, and a laminating unit configured to integrate laminar members laminated within a laminating hole by blanking the material, a laminated core member being manufactured by interlayer adhesion between the laminar members, and the laminating unit includes an adhesive hardener to harden the adhesive located between the laminar members so as to integrate the laminar members passing through the laminating hole, and pinchers provided under the adhesive hardener to apply lateral pressure to the laminated core member so as to prevent falling of the laminated core member. Since the laminated core members may be stably extracted, damage to the laminated core member due to falling may be prevented and the laminated core members in an aligned state may be extracted.
