Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing skin treatment devices often cause injuries due to uneven abrasive surface velocities and inefficient treatment due to improper adjustment of rotational speed, and are difficult to handle for specific or small skin regions.
Innovation Solution
A disc-shaped skin treatment device with a housing and drive mechanism, featuring a first skin treatment surface oriented perpendicular to the rotational axis and a second surface oriented radially, allowing for different surface characteristics to compensate for velocity differences and provide efficient treatment without harming the skin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If abrasive material is present on both circumferential surface and axial surface of the cap, then the device can provide multiple treatment functions, but different velocities of abrasive surface areas occur causing skin injuries and inefficient treatment
Solution Approach 1:
The skin treatment element is divided into two separate treatment surfaces: a first treatment surface on the axial end and a second treatment surface on the circumferential surface. Each surface can be independently configured with appropriate abrasive characteristics, allowing them to be optimized for their specific functions without the velocity inconsistency problems that affect unified abrasive caps.
Solution Approach 2:
Different surface characteristics are applied to different locations of the skin treatment element. The first treatment surface on the axial end has different properties than the second treatment surface on the circumferential surface, allowing each region to be optimized for its specific treatment purpose while avoiding the harmful velocity variations that occur when a single abrasive cap is used for multiple functions.
2Productivity
If rotational speed is adjusted for optimal performance, then treatment efficiency improves, but inadequate adjustment causes burning or inefficient treatment
Solution Approach 1:
The first and second treatment surfaces are designed with different surface characteristics that are each optimized for their specific operational requirements. This allows each surface to function effectively at appropriate rotational speeds without requiring complex speed adjustments, as the surfaces are inherently suited to their respective treatment tasks.
Solution Approach 2:
The device allows selective engagement of different treatment surfaces based on treatment requirements. By choosing which surface to use for a given treatment area or condition, the system dynamically adapts to different treatment needs without requiring speed adjustments that could cause harm or inefficiency.
3Reliability
If a drum assembly with circumferential abrasive coating is used, then the problem of different velocities is overcome, but the geometry is difficult to handle and not well suited for treating small skin regions
Solution Approach 1:
Instead of using a single large drum assembly, the invention segments the treatment element into a compact disc-shaped structure with two distinct treatment surfaces. This segmentation creates a more manageable size that is easier to handle and better suited for treating small or specific skin regions while maintaining the velocity consistency benefits of the drum design.
Solution Approach 2:
The invention adds an axial dimension to the treatment surfaces by placing a first treatment surface on the axial end of the disc, in addition to the circumferential second treatment surface. This dimensional expansion provides treatment versatility without requiring a large drum geometry, making the device more compact and easier to handle for specific skin region treatments.
