Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional skincare devices are inconvenient to use and may cause skin issues due to their design, as they require manual handling and often rely on adhesives for attachment, which can lead to separation from the skin and skin troubles.
Innovation Solution
A patch-type skincare device with a flexible, thin design incorporating a light source unit, cover members for protection, and a connection cable for power supply, allowing it to be attached to the skin without adhesives, featuring LEDs emitting light in a specific wavelength band and optionally including a current applying member for enhanced skin treatment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional skincare devices are designed for manual handling, then they can provide light therapy functions, but they are inconvenient to use and cannot be attached to the skin
Solution Approach 1:
The patent applies this principle by using a flexible substrate as the base of the skincare device, allowing it to conform to and adhere to curved skin surfaces. The flexible substrate enables the device to be attached directly to the skin without manual handling, resolving the contradiction between ease of operation and adaptability to skin contours.
Solution Approach 2:
The patent transitions the device from a handheld three-dimensional object to a two-dimensional patch that can be applied flat against the skin surface. This dimensional change allows the device to conform to skin contours and be attached without manual handling, improving both convenience and adaptability.
2Reliability
If adhesive materials are used to attach the device to skin, then the device can be fixed in place, but skin troubles may occur due to the adhesive material
Solution Approach 1:
The patent removes the adhesive layer from the device structure, eliminating the source of skin irritation. Instead of using adhesive materials for attachment, the device relies on the flexibility and conformability of the substrate to maintain contact with the skin, thereby ensuring attachment stability without causing skin troubles.
Solution Approach 2:
The flexible substrate itself provides the attachment function through its physical properties, eliminating the need for separate adhesive materials. The substrate's ability to conform to skin contours and maintain contact represents a self-service attachment mechanism that avoids harmful adhesives while ensuring reliable fixation.
3Strength
If the device is made with rigid structure to protect internal components, then components are protected, but the device cannot be attached to curved skin surfaces
Solution Approach 1:
The patent uses a flexible substrate that can bend and conform to curved skin surfaces while still providing structural support and protection for the LED components. This flexible base resolves the contradiction by maintaining component protection through its structural integrity while enabling adaptation to curved surfaces through its flexibility.
Solution Approach 2:
The device employs a composite structure combining the flexible substrate with protective layers and LED components. This composite design allows the device to maintain structural strength for component protection while the flexible substrate enables conformability to curved skin surfaces.
