Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple metal springs or magnetic springs are combined to enable nonlinear motion of the mover relative to the stator, then the nonlinear motion capability is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent changes the geometric parameters of the elastic connector by introducing transition-connecting portions with sequentially decreasing sizes. This parameter modification enables the single elastic connector to achieve nonlinear motion characteristics without requiring multiple springs or complex assemblies, thus resolving the contradiction between motion capability and structural complexity
Solution Approach 2:
The patent employs composite structure design by combining the elastic connector with transition-connecting portions that have varying cross-sectional dimensions. This composite geometric structure allows the single component to exhibit nonlinear elastic behavior, replacing the need for multiple metal or magnetic springs while maintaining the desired motion characteristics
2Adaptability or versatility
If multiple metal springs or magnetic springs are combined to enable nonlinear motion of the mover relative to the stator, then the nonlinear motion capability is improved, but the manufacturing cost increases
Solution Approach 1:
The patent merges the functions of multiple springs into a single elastic connector by integrating transition-connecting portions with varying geometries. This consolidation reduces the number of parts, simplifies assembly, and lowers manufacturing costs while maintaining the nonlinear motion capability that would otherwise require multiple expensive components
Solution Approach 2:
By modifying the geometric parameters of the elastic connector through sequentially decreasing transition-connecting portions, the patent achieves nonlinear motion characteristics in a single, cost-effective component rather than requiring expensive assemblies of multiple metal or magnetic springs
3Device complexity
If a linear spring is used for the spring connection structure, then the structure is simple and cost-effective, but the mover can only perform telescopic movement in one direction
Solution Approach 1:
The patent transforms a simple linear spring structure into a nonlinear spring connection structure by introducing transition-connecting portions with sequentially decreasing sizes. This parameter modification enables the elastic connector to provide restoring forces for complex nonlinear motion while maintaining structural simplicity and avoiding the need for multiple components
Solution Approach 2:
The elastic connector is segmented into distinct functional regions including the first end, second end, and intermediate transition-connecting portions. This segmentation allows each region to contribute differently to the overall elastic behavior, enabling nonlinear motion capabilities while keeping the entire structure as a single integrated component

AI summary
The present disclosure discloses a nonlinear spring connection structure and a motor. The nonlinear spring connection structure includes a stator, a mover and an elastic connector provided between the stator and the mover. The elastic connector includes a first end connected with the stator, a second end connected with the mover and at least two transition-connecting portions connected between the first end and the second end. The at least two transition-connecting portions extend from the first end towards the second end with sequentially decreasing sizes. An elastic connector is provided between a stator and a mover. In practice, the elastic connector, through deformation of itself, provides a restoring force for the mover during movement, so that the mover can perform a linear movement relative to the stator. In this way, a nonlinear spring connection structure is simpler and manufacturing cost of the nonlinear spring connection structure is reduced.
