Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rigid metal housing is used to electrically connect shield layers, then electrical connection between shield layers is achieved, but the splicing structure cannot adapt to different cable arrangements and angles
Solution Approach 1:
The patent replaces the rigid metal housing with a flexible shield tube that can be deformed and bent to accommodate different cable arrangements and angles. The flexible tube maintains electrical connection between shield layers while adapting to various spatial configurations, eliminating the need for angle-specific rigid housings.
Solution Approach 2:
The splicing structure transitions from a static rigid housing to a dynamic flexible tube that can change its shape and orientation. This allows the same flexible tube component to adapt to different cable arrangements by being bent or positioned at various angles during installation.
2Reliability
If a rigid metal housing with multiple components is used for splicing, then electrical connection and mechanical support are provided, but the number of assembly steps and components increases
Solution Approach 1:
The patent merges multiple functions (electrical connection, mechanical support, shielding) into a single flexible shield tube component, eliminating the need for separate rigid housing, mounting brackets, and multiple fastening elements. This consolidation reduces assembly steps while maintaining connection reliability.
Solution Approach 2:
The flexible shield tube serves multiple functions simultaneously: it provides electrical connection between shield layers, mechanical support for the spliced cables, electromagnetic shielding, and flexibility for different arrangements. This multi-functionality reduces the total number of components needed.
3Reliability
If conventional splicing techniques are used for shielded cables, then conductor connection is achieved, but the shield layer connection becomes complex requiring multiple components
Solution Approach 1:
The flexible shield tube replaces complex rigid housing structures for shield layer connection with a simple flexible tube that can be easily positioned and connected. The tube maintains electrical continuity between shield layers while accommodating conductor connections underneath.
