Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional ribbon splitting devices with multiple blades are used, then different subset sizes can be achieved, but device complexity increases and blade replacement becomes time-consuming
Solution Approach 1:
A single reciprocating member with a universal blade design performs multiple functions by creating different tear patterns. The blade generates initial tears at varying distances from the ribbon edge depending on the selected access point position, eliminating the need for multiple specialized blades while maintaining adaptability to create different fiber subset sizes.
Solution Approach 2:
The system uses a movable access point mechanism that dynamically adjusts the position where the blade initiates the tear. By changing the access point position along the ribbon width, the same blade creates different tear distances from the edge, enabling variable fiber subset separation without physical blade changes.
2Reliability
If conventional ribbon splitting devices are used, then fiber separation can be achieved, but the devices are too large to be easily manipulated at cable access points
Solution Approach 1:
The ribbon splitting tool is nested within a cable assembly housing that provides structural support and guides the operation. The compact reciprocating member fits within the confined space of the cable access point, allowing the separation function to be performed in-situ without requiring external manipulation of large devices.
Solution Approach 2:
The device separates the fiber separation function from the cable structure by using a distinct reciprocating member that operates independently within the cable assembly. This segmented approach allows the splitting mechanism to be compact and easily manipulated while the cable housing provides the necessary structural framework.
3Ease of operation
If cover members are separated during shearing, then access to blades is improved, but blade misalignment may occur causing fiber damage
Solution Approach 1:
The system uses a movable access point mechanism that pre-positions the blade at the correct location before the shearing action occurs. By establishing the proper blade-to-ribbon alignment in advance through controlled access point movement, the risk of misalignment-induced fiber damage is prevented before the critical shearing moment.
Solution Approach 2:
The movable access point mechanism provides continuous feedback on blade position relative to the ribbon during the shearing operation. This feedback ensures the blade remains properly aligned with the intended tear location, preventing misalignment and associated fiber damage while maintaining ease of operation.
