Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a complex massage mechanism with multiple components is used to provide pain relief during depilation, then the painkiller effect is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The invention extracts the essential pain relief function from complex massage mechanisms and implements it through a single vibrating element that contacts the skin directly, eliminating the need for complex pads, motors, and control systems while maintaining the analgesic effect
Solution Approach 2:
The invention changes the physical state of the contact element from static to vibrating, using vibration frequency and amplitude as the key parameters to achieve pain relief during depilation, thereby simplifying the overall device architecture
2Object-affected harmful factors
If traditional massage pads with complex mechanisms are used for pain relief, then the painkiller effect is achieved, but the manufacturing cost increases
Solution Approach 1:
The invention uses a simple, inexpensive vibrating element that can be easily manufactured and replaced if needed, eliminating the need for expensive, complex massage mechanisms while maintaining the pain relief function
Solution Approach 2:
The vibrating element serves dual functions: it contacts the skin during depilation and simultaneously provides pain relief through vibration, eliminating the need for separate expensive massage mechanisms
3Productivity
If hair is pulled out close to the skin for better depilation results, then the effectiveness of hair removal is improved, but the pain experienced by the user increases
Solution Approach 1:
The vibrating element is positioned to contact the skin before and during the hair pulling action, preparing the skin and nerve endings in advance to reduce the perception of pain when hairs are pulled out close to the skin
Solution Approach 2:
The invention converts the harmful pain stimulus into a beneficial effect by using vibration to desensitize the skin, allowing effective close-to-skin depilation while reducing user 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 provides effective pain relief during hair removal with a simpler, more affordable design that ensures efficient hair removal close to the skin, reducing user discomfort and manufacturing costs.
Implementation Method 1
The purpose of said elongated element is to amplify the vibration of the shutter and to transmit it to the skin to create stimuli. The user thus perceives less pain due to the treatment
