Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If side firing is used to irradiate laser in a lateral direction of the optical fiber, then the flexibility of laser irradiation is improved, but the ability to confirm irradiation position and direction deteriorates
Solution Approach 1:
An indication member is introduced as an intermediary element that provides X-ray visibility to the optical fiber assembly. This mediator allows the confirmation of irradiation position and direction without altering the side firing capability, resolving the information loss problem while maintaining flexibility
Solution Approach 2:
The indication member utilizes differential X-ray absorption properties (analogous to color changes in visible light) to create visible contrast between the indication member and surrounding tissues in X-ray images, enabling clear identification of the optical fiber position and light emitting surface orientation
2Ease of operation
If the light emitting surface is cut at an angle for lateral irradiation, then the laser irradiation direction is improved, but the precision of irradiation positioning deteriorates
Solution Approach 1:
The indication member is designed with asymmetric features (such as asymmetric patterns or shapes) that create distinctive X-ray imaging characteristics. This asymmetry allows precise determination of the light emitting surface orientation and position, compensating for the directional irradiation configuration
