Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate instruments and external equipment are used for sinus dilation, then comprehensive treatment functions can be achieved, but device complexity and operational complexity increase
Solution Approach 1:
The patent combines multiple separate instruments (dilation balloon, aspiration catheter, irrigation catheter, lighting system) into a single integrated probe assembly. The balloon catheter, aspiration lumen, irrigation lumen, and waveguide are all incorporated into one unified device that can be inserted through a single nostril, eliminating the need for multiple separate instruments and reducing procedural complexity.
Solution Approach 2:
The integrated instrument system performs multiple functions simultaneously: dilation of sinus ostia, aspiration of secretions, irrigation of sinus cavities, and trans-illumination for imaging. This multi-functional capability allows a single device to replace multiple specialized instruments while maintaining comprehensive treatment ability.
2Illumination intensity
If external light sources and image guidance systems are used, then trans-illumination and imaging capabilities are achieved, but the number of equipment requirements and procedural complexity increase
Solution Approach 1:
The waveguide is nested within the protective sheath of the catheter, extending along its length. This integrated optical fiber system is contained within the instrument structure itself, eliminating the need for external lighting equipment while providing trans-illumination capability through the sinus tissues.
Solution Approach 2:
The waveguide integrates lighting and imaging functions directly into the catheter system, allowing trans-illumination and potential imaging capabilities without requiring separate external light sources or image guidance systems.
3Adaptability or versatility
If multiple操作步骤 are used for sinus treatment, then comprehensive treatment can be achieved, but treatment time and procedural complexity increase
Solution Approach 1:
The instrument enables continuous simultaneous performance of dilation, aspiration, and irrigation operations. The balloon can be inflated while aspiration and irrigation continue uninterrupted, maintaining continuous therapeutic action rather than requiring sequential steps with transitions between different instruments.
Solution Approach 2:
Multiple treatment functions (dilation, aspiration, irrigation) are combined into a single instrument that can perform all operations simultaneously through a single insertion point, reducing the number of procedural steps and overall treatment time.
