Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separation layer is placed between the sheath and metallic layer to facilitate separation, then ease of operation is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The invention removes the separation layer from the cable structure, extracting the element that caused complexity while maintaining the desired separation functionality through the inherent properties of the sheath-metallic layer interface
Solution Approach 2:
The sheath and metallic layer are designed to separate automatically through their inherent structural properties without requiring an additional separation layer or extra processing steps, allowing the system to serve itself
2Ease of operation
If adhesion controlling films are applied to control bonding between sheath and metallic layer, then ease of operation is improved, but manufacturing cost and process complexity increase
Solution Approach 1:
The invention eliminates adhesion controlling films from the cable structure, removing the source of manufacturing complexity while achieving the desired separation characteristics through the fundamental interface design between the sheath and metallic layer
Solution Approach 2:
The invention modifies the physical and chemical parameters of the sheath and metallic layer surfaces to achieve appropriate adhesion characteristics without requiring additional films or coatings, simplifying the manufacturing process
3Ease of operation
If conventional separation methods are used, then ease of separation is improved, but material consumption and manufacturing cost increase
Solution Approach 1:

AI summary
The present disclosure provides an optical fiber cable (102) including a plurality of optical transmission elements (104), and a metallic layer (108) surrounding the plurality of optical transmission elements (104). Further, the optical fiber cable (102) includes a sheath (114) surrounding the metallic layer (108), wherein the sheath (114) is at least in partial contact with the metallic layer (108). An inner surface of the sheath (114) has a first set of ribs (110) that are deformed at substantial regular intervals along the length of the sheath (114). The arrangement of the optical fiber cable (102) allows an easy separation/peel off of the sheath (114) from the metallic layer (108) in a cost-effective manner as it does not require any additional material or tool. The structure of the optical fiber cable (102) reduces bonding between the sheath and the metallic layer.
