Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a long optical fiber is used to transmit light to the affected area, then the light can reach the target site, but the light energy decreases and brightness becomes weak
Solution Approach 1:
The optical fiber is divided into multiple segments with different lengths. The operator can select and connect appropriate fiber segments based on the specific procedural needs, ensuring optimal light transmission without excessive length that would cause energy loss
Solution Approach 2:
The system allows changing the optical fiber length parameter to match different procedural requirements. By optimizing the fiber length parameter, the patent maintains sufficient light brightness while minimizing energy loss in the transmission medium
2Ease of operation
If multiple equipment components are placed in a narrow space for the injection procedure, then the procedure can be performed, but spatial limitations arise and performing procedures from various angles becomes challenging
Solution Approach 1:
The patent combines the light source, optical fiber, injection needle, and syringe into an integrated system. This merging of components reduces the number of separate equipment pieces needed in the procedural space, improving accessibility while maintaining full functionality
Solution Approach 2:
The injection device is designed to perform multiple functions (illumination, drug delivery, positioning) through a single integrated system, eliminating the need for separate specialized equipment and reducing spatial requirements in the procedural area
3Measurement precision
If extensive experience and training are required for percutaneous vocal cord injection, then operator proficiency can be achieved, but the learning curve is steep and entry barrier is high
Solution Approach 1:
The optical fiber acts as an intermediary that provides visual guidance to the operator during the injection procedure. This intermediary tool enables less experienced operators to achieve accurate positioning by following the light guidance, reducing the reliance on extensive training and experience
4Illumination intensity
If the optical fiber length is increased to reach the affected area, then light transmission is possible, but production costs increase
Solution Approach 1:
The optical fiber is provided in segmentable lengths that can be connected as needed. This allows the system to use shorter, less expensive fiber segments for nearby procedures while still having the capability to extend to longer lengths when required, optimizing the balance between light delivery capability and manufacturing cost
