Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multifunctional electric groomers face issues with cumbersome assembly processes and potential loss of tool bits due to their modular design, limiting user convenience and functionality.
Innovation Solution
A multifunctional electric groomer with a casing that houses and easily switches between blade sets, utilizing a magnetic clutch coupling and support structures to allow quick selection and use of different functions without additional assembly, including a nose hair trimmer, hair clipper, and shaver, with each blade set having an operating and housed position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple independent tool bits are provided for different functions, then the device can achieve multiple functions, but the assembly process becomes troublesome and tool bits are easy to lose
Solution Approach 1:
The patent combines multiple independent tool bits (shaver, hair clipper, nose hair trimmer) into a single integrated device body. Each blade set is permanently mounted within the device housing, eliminating the need for users to assemble or disassemble separate tool bits. The driving module's output shaft can dynamically couple with different blade sets through internal mechanical structures, allowing function switching without external assembly operations.
Solution Approach 2:
The device employs a universal driving module that can drive multiple different blade sets through dynamic coupling mechanisms. The output shaft is designed to engage with different blade sets (shaver blade set, hair clipper blade set, nose hair trimmer blade set) depending on the selected function, allowing a single device to perform multiple grooming functions without requiring separate independent tools.
2Adaptability or versatility
If multiple independent tool bits are provided for different functions, then the device can achieve multiple functions, but the device complexity increases
Solution Approach 1:
The patent implements a nested structure where multiple blade sets are housed within a single device body. The shaver blade set, hair clipper blade set, and nose hair trimmer blade set are all contained within the same housing, with each blade set having its own designated chamber or mounting position. This nesting approach consolidates multiple functions into one compact unit, reducing the number of separate components users need to manage.
Solution Approach 2:
The device incorporates dynamic coupling mechanisms that allow the driving module's output shaft to selectively engage with different blade sets. The coupling structure can dynamically switch between different blade sets based on the selected function, enabling a single mechanical drive system to control multiple cutting functions without requiring separate motor units for each tool.
3Adaptability or versatility
If a double-shaft motor is used to drive shaver and hair cutter sets, then two functions are achieved, but more hair trimming functions cannot be added
Solution Approach 1:
The patent employs a universal driving module with an output shaft designed to accommodate multiple types of blade sets beyond just shaver and hair clipper functions. The coupling mechanism is designed to dynamically engage with different blade set configurations, allowing the addition of nose hair trimmer and other grooming functions without requiring additional motor shafts or separate motor units.
Solution Approach 2:
The device separates the cutting functions into independent blade set modules that can be independently selected and engaged. Each blade set (shaver, hair clipper, nose hair trimmer) is a separate modular component that interfaces with the common driving module through standardized coupling mechanisms, allowing flexible configuration and future expansion of functions without redesigning the core motor structure.

AI summary
A multifunctional electric groomer including a casing in which a driving module is provided, at least two blade sets, each of which is equipped with a support, one end of the support fixing the blade set and the other end of the support being hinged on the casing, with the hinge points of the supports successively arranged along the direction of the output shaft of the driving module. Each of the blade sets has a housed position and an operating position to dynamically couple with the driving module. A clutch coupling is provided between the output shaft of the driving module and the input shaft of the blade set.
