Solution Overview
Problem
Existing laser devices for skin treatment and beauty care have a complex configuration with separate light radiating and receiving units, leading to increased volume and thermal damage when used for disease diagnosis.
Innovation Solution
A tip for a laser handpiece with integrated light radiating and receiving modules, allowing for adjustable laser energy and focus size to minimize thermal damage and simplify the device configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a light radiating unit and a light receiving unit are separately installed in a laser device, then the device can perform both laser treatment and light reception functions, but the device configuration becomes complicated and the volume increases
Solution Approach 1:
The patent integrates the light receiving unit directly into the tip structure that is already part of the laser handpiece. The tip includes both the light radiating portion (through which laser passes) and the light receiving portion (with photodetector) as integrated components, eliminating the need for separate light receiving devices and simplifying the overall system configuration while maintaining dual functionality
2Adaptability or versatility
If a light receiving unit is separately installed from the light radiating unit, then both functions can be performed, but the device volume increases
Solution Approach 1:
The light receiving unit is merged into the tip structure, sharing the same physical space and mounting interface as the light radiating unit. The tip is mounted on the laser handpiece output and contains both the radiating aperture and the photodetector-based receiving unit in close proximity, significantly reducing the overall device volume compared to separate installations
3Power
If high energy lasers are used for skin treatment purposes, then effective treatment can be achieved, but thermal damage occurs to the skin when used for diagnosis
Solution Approach 1:
The patent employs a dual-mode operational capability where the laser energy can be dynamically adjusted based on the application. For treatment mode, high energy pulses (100-1600 mJ) are delivered; for diagnosis mode, the system switches to lower energy levels to avoid thermal damage while still enabling effective spectroscopic analysis. This dynamic adjustment is controlled through the device's processing unit that monitors operational parameters

Function Achieved in This Case
Enables effective disease diagnosis and skin age measurement using existing laser devices with reduced thermal risk and simplified device design by integrating light radiating and receiving functions into a single tip.
Implementation Method 1

AI summary
According to one embodiment, a tip for a laser handpiece includes: a light radiating module configured to radiate a laser toward a target; and a light receiving module configured to receive at least a portion of light which is generated by the laser radiated onto the target as received light. The light radiating module includes: a base which has an inner space formed therein to allow the laser to pass therethrough; a fixing portion which is coupled to a lower portion of the base and has a penetrating hole formed therein to allow the laser to pass therethrough; and a module connecting member which is interposed and fixed between the base and the fixing portion.
