Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electromagnetic machines face challenges in effectively reducing vibrations transmitted to or from the stator core, as current rigid metal bars used for attachment to a surrounding frame do not provide sufficient flexibility or adjustability for accurate alignment and vibration isolation.
Innovation Solution
A suspension system utilizing wire rope members with attachment devices to support the stator core, allowing for flexible vibration isolation and adjustable pre-tension to align the stator core accurately, incorporating a rigid frame structure with upper and lower portions and multiple wire rope members for enhanced torque resistance and vibration reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid metal bars are used to connect the stator core to the frame, then structural strength and stability are improved, but vibration isolation capability deteriorates
Solution Approach 1:
The patent replaces rigid metal bars with flexible wire rope members that have elastic properties. These wire ropes can deform under vibration loads, absorbing and isolating vibrations while still providing structural support. The flexible nature of the wire ropes allows them to act as vibration dampers, reducing the transmission of harmful vibrations between the stator core and the frame.
Solution Approach 2:
The patent changes the physical parameters of the connection elements from rigid (metal bars) to flexible (wire ropes with elastic properties). This parameter change allows the connection elements to exhibit both strength and vibration isolation capabilities. The wire ropes can be tensioned to provide structural stability while their elastic properties enable them to absorb vibration energy.
2Ease of manufacture
If rigid metal bars are used for stator core attachment, then manufacturing simplicity is improved, but alignment adjustability deteriorates
Solution Approach 1:
The patent introduces adjustable and adaptable connection elements (wire ropes) that can be modified after installation. The wire ropes can be tensioned or adjusted to achieve precise alignment of the stator core, providing adaptability that rigid metal bars cannot offer. This dynamic adjustment capability allows for fine-tuning of the stator core position during assembly or maintenance.
3Object-affected harmful factors
If wire rope members are used instead of rigid bars, then vibration isolation is improved, but structural rigidity deteriorates
Solution Approach 1:
The patent changes the physical state and properties of the connection elements from rigid to flexible, utilizing the elastic properties of wire ropes. This parameter change enables the connection elements to provide vibration isolation through elastic deformation while maintaining sufficient structural stability through proper tensioning and configuration.
Solution Approach 2:
The patent employs wire rope members that combine different material properties - the steel wires provide strength and rigidity, while the overall rope structure with its ability to deform provides flexibility and vibration isolation. This composite structure achieves both vibration isolation and structural stability simultaneously.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system provides superior vibration isolation and adjustable alignment, improving the operational stability and accuracy of electromagnetic machines by using flexible wire rope members that offer greater flexibility and adjustability compared to traditional rigid key bars.
Implementation Method 1
Vibrations originating from or transmitted to the stator core are currently reduced by connecting the stator core to a surrounding rigid frame using a plurality of spring bars—rigid metal bars that incorporate a flexible portion intended to absorb such vibrations
