Structural Cable With Inner Housing For Functional Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current structural cables lack enhanced functional capabilities, particularly in terms of durability and adaptability to environmental conditions, such as resistance to ultraviolet rays and combined effects of rain and wind, while also requiring improved integration of functional components like lighting and thermal management.
Innovation Solution
The structural cable design incorporates a high-density polyethylene sheath with a helical rib structure for enhanced durability and UV resistance, along with a housing that accommodates functional components like light-radiating modules and a cavity system for thermal management, allowing for the integration of various functional elements within the cable's structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a simple sheath structure is used, then manufacturing is easier and cost is lower, but durability and resistance to environmental factors are insufficient
Solution Approach 1:
The cable structure is segmented into distinct functional layers: an inner housing containing functional components, an intermediate layer with functional elements, and an outer sheath providing environmental protection. This segmentation allows each layer to be optimized independently for its specific function while maintaining overall durability without excessive complexity.
Solution Approach 2:
The patent employs composite material structures combining different materials with complementary properties: the outer sheath uses UV-resistant materials for environmental protection, the inner housing uses durable materials for structural integrity, and functional layers incorporate specialized materials for their specific purposes. This composite approach enhances durability without requiring overly complex single-material solutions.
2Adaptability or versatility
If functional components are integrated into the cable, then adaptability and functionality are enhanced, but device complexity increases
Solution Approach 1:
The patent implements a nested structure where the inner housing containing functional components is positioned within the outer sheath, and functional layers are integrated between these layers. This nesting approach allows multiple functional elements to be incorporated into the cable without significantly increasing external dimensions or manufacturing complexity, as each component fits within the hierarchical structure.
Solution Approach 2:
The cable design incorporates universal structural elements that serve multiple functions: the inner housing provides both structural support and containment for functional components, the functional layers serve both as structural elements and as carriers for functional components, and the outer sheath provides both mechanical protection and environmental resistance. This multi-functionality reduces the need for separate dedicated components, thereby limiting complexity growth.
3Reliability
If environmental resistance is improved through material selection, then durability increases, but manufacturing precision requirements increase
Solution Approach 1:
The patent addresses environmental resistance by changing material parameters such as UV resistance properties, chemical resistance characteristics, and mechanical strength parameters. These parameter changes are achieved through material selection and formulation rather than through complex manufacturing processes, thereby improving environmental resistance without significantly increasing manufacturing precision requirements.
