Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a single laser treatment system is designed with specific optical characteristics for a specific treatment area, then the treatment precision and effectiveness are improved, but the adaptability to different treatment areas and techniques deteriorates
Solution Approach 1:
The laser treatment system is segmented into a base unit and multiple interchangeable handpieces. Each handpiece is designed with specific optical characteristics and cooling requirements tailored to its treatment function. The cooling circuit is similarly segmented into multiple loops that can be selectively activated based on which handpiece is attached, allowing each component to be optimized for its specific purpose while maintaining overall system versatility.
2Adaptability or versatility
If multiple handpieces are provided to provide different treatment characteristics, then the versatility is improved, but the device complexity and cost increase
Solution Approach 1:
The base unit is designed as a universal platform that can accommodate multiple different handpieces through standardized mechanical and fluid connections. The cooling system uses a multi-loop circuit design with selective activation, allowing the same base unit to support various handpieces without requiring separate cooling systems for each. This universal design reduces overall system complexity compared to providing completely separate laser systems for each treatment type.
3Object-affected harmful factors
If integral cooling is provided to the treatment device tip, then the patient comfort and safety are improved, but the adaptability to different application techniques deteriorates
Solution Approach 1:
The cooling system is designed to be dynamic rather than static. The multi-loop cooling circuit can selectively activate different cooling paths based on which handpiece is attached and what treatment mode is being used. This allows the cooling characteristics to adapt dynamically to different application techniques, maintaining effective skin protection while supporting various treatment modalities including vacuum-assisted techniques.
