Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication lines face issues such as signal quality degradation and increased signal loss due to external dust or foreign matter attachment, and excessive bending leading to gaps that allow external interference. Additionally, these lines experience excessive electromagnetic field leakage, resulting in incomplete signals and increased noise.
Innovation Solution
A communication line design featuring a core portion with a circular cross-section, ribs extending from the core, a shielding portion with slits, and a cover portion to prevent external interference. The ribs and shielding portion are designed to be misaligned with the electromagnetic wave signal polarization to minimize leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional communication lines are used without protective structures, then manufacturing cost is low and installation is simple, but external dust or foreign matter attaches to the communication line causing signal quality degradation and increased signal loss
Solution Approach 1:
The communication line is segmented into functional components: a core portion for signal transmission, a shielding portion with slits for electromagnetic field control, and a cover portion for dust protection. This segmentation allows each component to perform its specific function optimally while maintaining overall system reliability.
Solution Approach 2:
The communication line employs a composite structure combining dielectric materials for the core and shielding portions with protective cover materials. This composite design provides both electromagnetic shielding and physical protection against dust, resolving the contradiction between reliability improvement and structural complexity.
2Adaptability or versatility
If conventional communication lines are bent to fit narrow or complex spaces, then adaptability improves, but excessive force causes gaps to form allowing external dust or foreign matter to enter
Solution Approach 1:
The communication line incorporates a flexible dielectric core portion that can be bent to fit narrow or complex spaces without forming gaps. The flexible structure maintains continuous shielding and coverage even during bending, preventing dust entry while preserving signal quality and enabling adaptability.
Solution Approach 2:
The shielding portion and cover portion are designed with sufficient thickness and structural strength beforehand to withstand bending forces without forming gaps. This preemptive design ensures that even when bent to fit complex spaces, the communication line maintains its protective function and signal integrity.
3Reliability
If conventional communication lines are used without shielding structures, then manufacturing is simple, but electromagnetic field leakage occurs causing signal incompleteness and increased noise
Solution Approach 1:
The shielding portion is designed with local quality features including strategically placed slits that allow controlled electromagnetic field management. The shielding structure provides targeted protection where needed while maintaining manufacturing feasibility through standardized components and assembly processes.
Solution Approach 2:
The shielding portion acts as an intermediary between the core communication line and the external environment. It controls electromagnetic field leakage through its slit structure while maintaining a manageable manufacturing process, thus improving signal integrity without excessive manufacturing complexity.
