Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If traditional methods are used to attach balancer weights to rotors, then the attachment is secure, but the manufacturing process becomes complex and difficult to automate
Solution Approach 1:
The attachment system is segmented into distinct functional components: the rod inserted through the core hole, the balancer weight with its weight hole, and the fixing member with the spring part. This segmentation allows each component to be independently manufactured and assembled, simplifying the overall attachment process and enabling automation.
Solution Approach 2:
The spring part automatically expands when the rod is inserted and tightly secures the balancer weight through elastic restoring force without requiring additional fastening operations. This self-service mechanism eliminates complex manual attachment steps and enables straightforward automated assembly.
2Productivity
If additional attachment structures and components are used to secure balancer weights, then the fixation is reliable, but the manufacturing efficiency decreases
Solution Approach 1:
The invention extracts the essential fixation function from complex multi-component attachment systems and implements it through a single integrated fixing member with a spring part. This eliminates unnecessary additional structures while maintaining reliable fixation through the elastic restoring force of the spring.
Solution Approach 2:
The spring part changes its physical parameter (expansion state) in response to rod insertion, transitioning from a compressed state to an expanded state that exerts tightening force. This parameter change enables automatic secure fixation without additional components or complex procedures.
3Ease of manufacture
If a simple attachment method is used for balancer weights, then manufacturing is easier and automation is improved, but the security of fixation may be compromised
Solution Approach 1:
The fixing member incorporates a dynamic spring part that automatically adjusts its expansion state based on the insertion of the rod. This dynamic response ensures reliable fixation through elastic restoring force while maintaining a simple, easy-to-manufacture structure without complex fastening mechanisms.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design simplifies the attachment of balancer weights, enhances manufacturing efficiency by reducing the need for additional attachment structures and components, and ensures secure fixation for improved rotational balance.
Implementation Method 1
The spring part may be elastically deformed to expand by the rod when the rod is inserted into the fixing hole, and tighten the rod by the action of an elastic restoring force generated in the spring part.

AI summary
A rotor capable of fixing a balancer weight by an easier method. The rotor includes a shaft; a core having a core hole penetrating the core in an axial direction; a rod configured to be inserted into the core hole so as to protrude from one end surface of the core in the axial direction to the one side in the axial direction; a balancer weight having a weight hole and placed on the end surface with the rod inserted into the weight hole; and a fixing member having a fixing hole and coming into contact with the balancer weight from the one side in the axial direction with the rod inserted into the fixing hole to fix the balancer weight by sandwiching the balancer weight with the end surface.
