Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a V-shaped groove is used to guide the optical fiber to the sheath removing blade, then the device structure is simple, but positional deviation occurs between the optical fiber and the blade
Solution Approach 1:
The guide structure is divided into multiple functional components: a V-shaped groove for initial fiber reception, positioning protrusions for precise lateral positioning, and a positioning hole for axial positioning. This segmentation allows each component to address specific positioning requirements, achieving high positioning accuracy without excessive overall complexity.
Solution Approach 2:
The guide structure acts as an intermediary between the optical fiber and the sheath removing blade. It includes a V-shaped groove that receives the fiber, positioning protrusions that mediate lateral positioning, and a positioning hole that mediates axial positioning, ensuring the fiber is accurately positioned relative to the blade before sheath removal.
2Ease of operation
If manual operation is used for sheath removal, then the device is simple to operate, but the success rate varies according to the worker
Solution Approach 1:
The guide structure enables self-positioning of the optical fiber through its geometric features. The V-shaped groove automatically centers the fiber, while the positioning protrusions and hole provide self-aligning constraints, allowing the system to position itself without requiring high operator skill or manual adjustment.
Solution Approach 2:
The guide structure transforms the operational parameters from manual dexterity requirements to simple insertion operations. By changing the geometric parameters of the guide (V-shape angle, protrusion dimensions, hole position), the system achieves reliable positioning regardless of operator variability, maintaining ease of operation while improving success rate.
3Volume of moving object
If the optical fiber has a small radius of curvature and bends, then the fiber can be stored efficiently, but positional deviation occurs during sheath removal
Solution Approach 1:
The guide structure provides beforehand cushioning for bent fibers through its geometric constraints. The V-shaped groove and positioning features are designed to accommodate fibers with small radii of curvature, providing gentle guidance that gradually straightens the fiber while maintaining positioning accuracy, thus cushioning against the adverse effects of bending before the sheath removal process.
4Productivity
If automation is introduced to improve working efficiency, then productivity increases, but the positioning accuracy deteriorates due to V-shaped groove limitations
Solution Approach 1:
The guide structure is segmented into multiple functional zones: a V-shaped groove zone for initial fiber reception and rough positioning, a positioning protrusion zone for precise lateral alignment, and a positioning hole zone for final axial positioning. This segmentation enables automated systems to achieve high positioning accuracy through a sequence of simple positioning actions, maintaining both productivity and precision.
