Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a separate supply pipe is used to deliver cleaning solvent to the nozzle, then the cleaning function is achieved, but the device complexity increases and manufacturing cost rises
Solution Approach 1:
The rotor shaft is designed to integrate multiple functions: it serves as both the rotating component for vibration generation and as the fluid supply channel. The through-hole in the rotor shaft replaces the need for a separate supply pipe, merging the structural and fluid delivery functions into a single component, thereby reducing part count and assembly complexity
Solution Approach 2:
The rotor shaft is designed as a multi-functional component that simultaneously performs mechanical rotation for vibration generation and acts as a fluid conduit for delivering cleaning solvent to the nozzle. This multi-functionality eliminates the need for dedicated supply piping and reduces overall device complexity
2Adaptability or versatility
If a built-in nozzle is used for cleaning, then the cleaning function is provided, but the adaptability to different objects and materials is limited
Solution Approach 1:
The nozzle system transitions from a fixed built-in configuration to a detachable and interchangeable design. Users can dynamically change nozzles based on cleaning requirements, allowing adaptation to different objects, surfaces, and cleaning scenarios while maintaining a relatively simple overall system structure
Solution Approach 2:
The nozzle is designed as a separate detachable component rather than being integrally built-in. This segmentation allows the nozzle to be independently selected, replaced, or adjusted based on specific cleaning needs, enhancing versatility without significantly increasing overall device complexity
3Power
If the vibrating part is mounted perpendicular to the nozzle pipe, then the vibration generation is achieved, but the active action on the water jet is limited
Solution Approach 1:
The rotor shaft with magnets rotates between stators to generate strong vibrational motion. This vibration is directly transmitted through the rotor shaft itself (which also serves as the fluid channel) to the nozzle, creating an active vibrating water jet that significantly enhances cleaning power compared to static or perpendicular vibration configurations

This design reduces costs and improves productivity by simplifying the internal structure, enhances user convenience with interchangeable nozzles, and effectively cleans objects using various solvents.
Implementation Method 1
These vibration motors convert electrical energy into mechanical energy, i.e., torque, by mediating the electromagnetic field in the gap between a stator and a rotor according to the so-called Fleming's left-hand rule
Implementation Method 2
a vibrating part coupled to opposite inner sides of the motor housing and providing vibration while rotating the rotor in forward and reverse directions

AI summary
The present invention relates to a vibration motor having a through hole formed in a rotor, in which: a rotor that penetrates and is coupled to a motor housing and a vibrating part plays a role of receiving a cleaning solvent and at the same time acts as a vibration transmission medium, and thus, no separate supply pipe is required, thereby contributing to cost reduction and productivity improvement; simplification of an internal structure assists in improving performance; a nozzle is detachably fixed to a front end of the rotor, and thus, various types of nozzles can be selectively replaced according to an object to be cleaned; and an object to be cleaned can be effectively washed by supplying various cleaning solvents such as water, oil, powder, and air to the through hole in the rotor.
