Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional rolling bearing is used without additional support structures, then the structure remains simple, but the bearing cannot be adjusted for assembly tolerance distortion and heat dissipation is insufficient
Solution Approach 1:
The patent applies this principle by using an elastic mesh (thin film structure) that surrounds the outer rim of the bearing. This elastic mesh can elastically deform to adjust the center axis position of the bearing, compensating for assembly tolerance distortions. The mesh also provides heat dissipation pathways while maintaining a relatively simple overall structure, thus improving bearing reliability without significantly increasing device complexity.
2Manufacturing precision
If the bearing structure is made more complex to allow center axis adjustment, then alignment precision improves, but the structure becomes more complicated
Solution Approach 1:
The elastic mesh acts as a flexible thin film structure that enables center axis adjustment through elastic deformation. This approach achieves precise alignment (improving manufacturing precision) while avoiding complex mechanical adjustment mechanisms, thus not significantly increasing device complexity.
Solution Approach 2:
The patent utilizes parameter changes by allowing the elastic mesh to change its physical state (elastic deformation) in response to thermal expansion and assembly tolerances. This enables dynamic adjustment of the bearing's center axis position, improving alignment precision without requiring complex mechanical adjustment devices.
3Reliability
If traditional bearing support structures are used, then the structure remains simple, but heat dissipation efficiency is low leading to increased abrasion
Solution Approach 1:
The elastic mesh surrounding the outer rim serves as both a structural support and a heat dissipation pathway. Its flexible thin film structure allows it to conform to the bearing outer rim while providing thermal conduction paths, improving heat dissipation efficiency without significantly complicating the overall bearing structure.
Solution Approach 2:
The patent effectively uses composite material principles by combining the traditional bearing structure with an elastic mesh material that has both mechanical support properties and thermal conduction properties. This composite approach simultaneously addresses structural requirements and heat dissipation needs, improving bearing durability while managing thermal energy loss.
