Solution Overview
Problem
Conventional light treatment apparatuses face challenges in delivering uniform treatment energy due to varying handpiece movement speeds and user skill levels, leading to inconsistent treatment effects.
Innovation Solution
A light treatment apparatus equipped with a sensing unit to detect movement information and a control unit that adjusts irradiation patterns and times to ensure overlapping treatment light areas, maintaining a predetermined overlap ratio, thereby minimizing the impact of handpiece speed and user skill on treatment consistency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If treatment light is irradiated at a predetermined period or by user's firing operation while the handpiece is moving, then the apparatus can perform treatment, but when the moving speed of the handpiece is not constant, uniform treatment cannot be achieved and treatment effect differs depending on user skill
Solution Approach 1:
The control unit receives movement information from the sensing unit (accelerometer, gyroscope, or camera) and adjusts the irradiation timing of treatment light based on the detected handpiece movement speed and position. This feedback mechanism ensures that treatment light is irradiated at appropriate intervals regardless of handpiece movement variations, achieving uniform treatment energy distribution while maintaining ease of operation
Solution Approach 2:
The system dynamically adjusts the irradiation timing of treatment light based on real-time handpiece movement characteristics. The control unit modifies the irradiation pattern according to detected movement speed and position, allowing the treatment process to adapt to varying operational conditions and maintain treatment consistency
2Productivity
If the handpiece moves faster than reference speed, then treatment area coverage increases, but treatment energy per area decreases leading to insufficient treatment effect
Solution Approach 1:
The control unit monitors handpiece movement speed via the sensing unit and adjusts irradiation timing accordingly. When faster movement is detected, the system increases irradiation frequency to maintain adequate energy delivery per unit area, ensuring treatment effectiveness is preserved even when productivity increases
3Manufacturing precision
If the handpiece moves slower than reference speed, then treatment energy per area increases, but treatment area coverage decreases leading to reduced productivity
Solution Approach 1:
The control unit detects reduced handpiece movement speed through the sensing unit and adjusts irradiation timing to reduce frequency when movement is slow. This prevents excessive energy accumulation in a small area while maintaining overall treatment coverage, balancing treatment quality with productivity
