Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a plastic snap-fit fastener is used for fixation, then the shaver head can be replaced, but the fastener causes wear and tear after long-term use, reducing fixation effect and service life
Solution Approach 1:
The patent replaces the plastic snap-fit fastener system with a metal mechanical fastening system consisting of a metal shaver head connector, positioning pins, and corresponding positioning grooves. This substitution eliminates the wear and tear issues of plastic while maintaining the replaceable functionality, thereby improving both adaptability and reliability simultaneously.
2Adaptability or versatility
If an assembly structure with button, spring, and connector is used, then the shaver head can be replaced, but the production and assembly process becomes complicated, increasing production cost and reducing production capacity
Solution Approach 1:
The patent extracts and eliminates unnecessary components from the assembly structure, removing the button, spring, and complex connector mechanisms found in conventional designs. The simplified structure relies on direct metal-to-metal engagement between the shaver head connector and positioning pins/grooves, significantly reducing part count and assembly complexity while preserving the replaceable shaver head functionality.
Solution Approach 2:
The patent segments the shaver into distinct modular components (shaver body and shaver head) with standardized metal connection interfaces. This segmentation enables easy replacement while simplifying the overall assembly structure, as each module can be independently manufactured and assembled without requiring complex fastening mechanisms.
3Adaptability or versatility
If multiple personal care products are prepared, then various functions are available, but it becomes difficult to keep and manage them
Solution Approach 1:
The patent implements a universal shaver head connector design that can accommodate different types of shaver heads (razor blades, trimmer heads, etc.) through standardized metal positioning interfaces. This multi-functionality allows users to replace different shaver heads based on needs while maintaining a single, unified connection system, thereby providing diverse functionality without increasing the complexity of keeping and managing multiple products.

AI summary
An amorphous alloy shaver having a replaceable shaver head, comprises a shaver body, a release plate is fixedly connected to a top of the shaver body, a side surface of the shaver body is provided with a switch, the side surface of the shaver body is provided with a display screen, the side surface of the shaver body is provided with a charging slot, and a replacement device is arranged at a top of the release plate. By means of co-cooperation of a pressing force of a pressing block and components in the replacement device such as an airbag, a pressing plate, a snap-fit fastener and a snap-fit block, operation of jacking the snap-fit fastener up by the airbag is realized, which enhances convenience of a user such that a worn shaver head is replaced conveniently, and a service life of the shaver is prolonged.
