Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial compressors face deformation issues during installation and use, leading to misalignment of bearings and potential failure, which increases maintenance costs and downtime.
Innovation Solution
A stability mechanism with a centrally-located support member and peripheral tie bars is integrated into the compressor frame to provide multi-directional support, preventing deformation and maintaining bearing alignment through the use of robust steel components and specific geometric configurations.

1Stability of the object's composition
If a traditional frame structure is used in the compressor, then the device complexity is low, but the frame undergoes deformation during installation and use leading to bearing misalignment
Solution Approach 1:
The frame is segmented into multiple functional components: a base structure, a centrally-located support member, and peripherally-located tie bars. This segmentation allows each component to perform a specific structural function, with the support member providing vertical stability and tie bars providing lateral rigidity, thereby preventing deformation while maintaining manageable complexity through modular design
Solution Approach 2:
Different regions of the frame are given different structural qualities: the centrally-located support member is designed with specific geometric configurations (such as triangular or X-bracing patterns) to provide vertical support and prevent bearing misalignment, while peripherally-located tie bars are designed with rigid connections to prevent lateral deformation. This localized optimization of structural properties addresses deformation issues without requiring complex reinforcement throughout the entire frame
2Ease of manufacture
If the frame structure is simplified for ease of manufacture, then the manufacturing cost is reduced, but the frame becomes susceptible to deformation under operational loads
Solution Approach 1:
The stability function is extracted from the main frame structure and implemented through separate, dedicated components: the centrally-located support member handles vertical stability and bearing alignment, while peripherally-located tie bars handle lateral rigidity. This extraction allows the main frame to remain simple and easy to manufacture, while the extracted stability components provide the necessary strength and deformation resistance through their specific geometric configurations and rigid connections
3Strength
If heavier steel components are used to prevent deformation, then the frame strength is improved, but the weight of the compressor increases
Solution Approach 1:
Instead of increasing material thickness or using heavier solid sections, the design utilizes geometric configurations in multiple dimensions: triangular bracing patterns, X-shaped support members, and peripheral tie bar arrangements. These multi-dimensional geometric structures provide high strength-to-weight ratios by distributing loads efficiently through their spatial configurations, preventing frame deformation without requiring excessive material weight

AI summary
A stability mechanism that can reduce deformation of a frame of a compressor. The stability mechanism can have a support member with an x-shaped configuration having a pair of peripheral members and diagonal components disposed therebetween. In use, the support member can work in combination with elongated “tie bars” to prevent deformation of the frame that may result from installation and/or use of the compressor.
