Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a movable pad element with displacement in the plane of the skin is used for pain relief, then the painkiller effect is achieved, but the device becomes bulky and constructionally complicated
Solution Approach 1:
The patent combines the depilation function and pain relief function into a single integrated head assembly. The oscillating element is integrated within the same head housing as the depilation rollers, eliminating the need for separate components and reducing overall device complexity while maintaining effective pain relief through skin friction.
2Object-affected harmful factors
If the oscillation frequency of the massaging element is increased for better pain relief, then the painkiller effect is enhanced, but the device requires more complex drive mechanisms
Solution Approach 1:
The patent introduces a cam mechanism as an intermediary element that converts the rotational motion of a single motor into high-frequency oscillations of the massaging element. The cam profile is designed to generate the required oscillation frequency without requiring complex direct-drive mechanisms, simplifying the overall drive system while achieving effective pain relief.
3Volume of moving object
If the depilation head is designed with integrated pain relief means, then the device becomes compact and robust, but the massaging element may be difficult to clean
Solution Approach 1:
The patent designs the head assembly as a separable component that can be easily removed from the main device body. The oscillating massaging element is positioned and constructed to allow access for cleaning, with surfaces that can be reached and maintained even when integrated within the compact head structure.
4Productivity
If the depilation roller pulls hairs close to the skin for better results, then the depilation effectiveness is improved, but the pain sensation is intensified
Solution Approach 1:
The patent positions the oscillating massaging element to act on the skin before and during the depilation process. By pre-massaging the treatment area and continuously frictioning the skin during hair removal, the device prepares the skin to tolerate close-to-skin depilation while reducing pain perception, enabling effective hair removal without excessive discomfort.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device effectively reduces pain during hair removal by massaging the skin, enhances blood microcirculation, and is easy to clean and maintain, with a compact and robust design that supports various skin treatments.
Implementation Method 1
A further object of the invention is a body care appliance provided with a cam and a rod secured to the movable shutter, the cam being mounted on a rod and intended to drive said massaging element
Implementation Method 2
This movement in the plane of the skin produces in particular a massaging action by friction performed just next to the zone of action of the depilation roller

AI summary
The apparatus (1) has a housing (2) that contains an electric motor and a gear train that is driven by the motor. An epilation cylinder (4) is rotatable about a depilation axis (Delta) that is provided parallel to a plane of a skin to be treated. A massaging element (7) i.e. bar, is in contact with the skin. A drive wheel is driven by the gear train. A bi-processing block (8) incorporates the messaging element and the epilation cylinder. The bi-processing block is interchangeably mounted on the housing of the apparatus.
