Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the coil is wound around a hollow support, then the structure is simple and easy to manufacture, but the hollow support is easy to deform, making it difficult to control the shape of the coil
Solution Approach 1:
The support structure changes from hollow to solid, fundamentally altering the structural parameter to eliminate deformation while maintaining manufacturability. The solid skeleton provides a stable winding surface that prevents coil shape distortion during the winding process.
Solution Approach 2:
The skeleton uses solid structural design with positioning protrusions that create a composite functional structure. The solid skeleton combined with positioning features provides both structural stability for coil shape control and manufacturing ease through standardized assembly processes.
2Manufacturing precision
If a solid skeleton structure with positioning protrusions is used, then the coil shape control is improved and winding speed is enhanced, but the device complexity increases
Solution Approach 1:
The skeleton is segmented into functional portions including positioning protrusions and connection interfaces. This segmentation allows each feature to serve its specific purpose while maintaining overall structural simplicity and ease of assembly with other components.
Solution Approach 2:
The positioning protrusions are integrated directly into the solid skeleton structure rather than being separate components. This merging reduces the total number of parts while achieving both coil shape control and simplified assembly with the coil and other components.

AI summary
The present application provides a vibration exciter, including a casing with an accommodating cavity, a stator assembly assembled in the casing, and a vibrator assembly assembled in the accommodating cavity and driven by the stator assembly to vibrate. The stator assembly includes a polar core fixed on an inner side of the casing and a magnetic steel fixed on one side of the polar core away from the casing. The vibrator assembly includes a skeleton elastically connected to the casing, a mass block fixed to the skeleton, and a coil wound around the outer side of the skeleton. The skeleton is integrally formed and has a solid structure. In the present application, since the skeleton is a solid structure formed integrally, the skeleton is not easy to be deformed when the coils are wound, and the shape of the coils can be controlled, thus having a better shape.
