Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If groove-pin connections are used to connect the actuating mechanism to the drive shaft, then torque transfer is achieved, but friction, noise, and wear increase
Solution Approach 1:
The patent replaces the mechanical groove-pin connection system with a magnetic coupling system. Magnets are arranged on the drive shaft and corresponding magnets on the actuating mechanism interact through magnetic fields to transfer torque, eliminating direct mechanical contact and thus reducing friction, noise, and wear while maintaining effective torque transfer.
Solution Approach 2:
The magnetic field serves as an intermediary between the drive shaft and the actuating mechanism. Instead of direct mechanical contact through groove-pins, the magnetic field mediates the torque transfer, allowing power transmission without physical contact and thereby eliminating the harmful effects of friction and wear.
2Device complexity
If groove-pin connections are used, then structural simplicity is maintained, but durability decreases due to wear
Solution Approach 1:
The mechanical groove-pin connection is replaced with a magnetic coupling system that uses magnetic fields for torque transfer. This substitution eliminates wear between moving parts, significantly improving durability and reliability while maintaining a relatively simple structure with magnets and magnetic couplings.
3Object-generated harmful factors
If resilient connection components like bellows or leaf springs are introduced, then friction and wear are reduced, but device complexity increases
Solution Approach 1:
The patent introduces a magnetic coupling system that replaces traditional mechanical connections. This substitution eliminates friction and wear by using magnetic fields instead of direct mechanical contact, while the added complexity is minimal, involving only the arrangement of magnets on the drive shaft and actuating mechanism.

AI summary
A depilating device (5) comprises a depilating body (10) which is rotatable about a rotation axis (R) extending in a longitudinal direction (L) with respect to the depilating body (10), an actuating mechanism (30) configured to act on the depilating body (10) so as to cause compression and extension of the depilating body (10) in the longitudinal direction (L) during rotational movement of the depilating body (10) about the rotation axis (R), and a driving mechanism (20) configured to drive the depilating body (10) and to also drive the actuating mechanism (30). The actuating mechanism (30) is connected to a drive shaft (21) of the driving mechanism (20) in a resilient fashion, such as through at least one leaf spring (51), which contributes to minimizing friction and noise in the depilating device (5), and which may also support one of compression and extension of the depilating body (10).
