Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric machinery rotors with low-speed and large-diameter designs face deformation issues during machining, transportation, and mounting, leading to increased costs and operational difficulties due to the need for reinforcement rings that either increase material costs or require high processing costs for temporary solutions.
Innovation Solution
A detachable reinforcement ring tooling system comprising multiple separate members and movable connection members that form an annular body, allowing for selective mounting on the rotor's outer circumference to enhance structural strength while reducing manufacturing and operational costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a permanent reinforcement ring is welded on the outer wall of the rotor yoke, then the rotor deformation is prevented, but the outer dimension and material cost of the electric machinery increase
Solution Approach 1:
The reinforcement ring is divided into multiple separate members (at least two) that can be independently positioned and connected. This segmentation allows the reinforcement structure to be distributed around the rotor circumference, providing effective support while reducing the total material required compared to a single continuous ring, thus decreasing the outer dimension and weight of the electric machinery.
Solution Approach 2:
The connection members include movable connections that allow the separate members to adjust their positions and orientations. This dynamic capability enables the reinforcement ring structure to adapt to rotor deformation during mounting, ensuring effective support is maintained while allowing for compact configuration that reduces overall dimensions.
2Stability of the object's composition
If a permanent reinforcement ring is welded on the outer wall of the rotor yoke, then the rotor deformation is prevented, but the material cost of the electric machinery increases
Solution Approach 1:
By segmenting the reinforcement ring into multiple separate members, the total quantity of reinforcement material required is reduced. The members can be strategically positioned at critical locations around the rotor circumference, providing effective deformation prevention with less material than a complete continuous ring, thereby reducing material cost.
Solution Approach 2:
The separate members of the reinforcement ring are positioned at specific locations around the rotor where deformation is most likely to occur. This localized reinforcement approach concentrates material where it is most needed, providing effective deformation prevention while minimizing the total material quantity and cost throughout the entire structure.
3Quantity of substance
If a temporary reinforcement ring is welded on the outer wall of the rotor yoke, then the material cost is not increased, but the rotor requires cutting, polishing, and preservation, so the processing cost is high
Solution Approach 1:
The movable connections enable the separate members to be easily adjusted and repositioned during mounting, eliminating the need for complex cutting and polishing operations. The dynamic structure can adapt to the rotor surface, providing effective reinforcement without requiring expensive post-processing operations, thus reducing processing cost while maintaining material cost efficiency.
4Ease of manufacture
If a detachable reinforcement ring tooling is used, then the manufacturing cost is reduced and assembly efficiency is improved, but the device complexity increases
Solution Approach 1:
The reinforcement ring tooling is segmented into multiple separate members connected by connection members, which simplifies manufacturing compared to producing a single complex continuous ring. Each separate member can be manufactured independently using standard processes, reducing tooling complexity and manufacturing cost while maintaining effectiveness.
