Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cable connections, particularly coaxial and HDMI cables, often go ungrounded or are improperly grounded during installation, leading to poor transmission signals and electromagnetic interference, which are time-consuming and costly to resolve.
Innovation Solution
A cable grounding plug assembly that provides electrical grounding for coaxial and HDMI cables at the point of use within a building, using a housing with electrodes and receptacles to connect the cables to the building's grounding circuit, ensuring proper grounding without increasing complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If cable connections are installed without grounding or with improper grounding, then installation complexity is reduced, but signal transmission quality deteriorates and electromagnetic interference increases
Solution Approach 1:
The grounding plug assembly is pre-configured with grounding electrodes and connection terminals before installation. The installer simply needs to connect the cable to the pre-prepared grounding structure, eliminating the need for complex grounding wire routing and connections during installation. This preliminary preparation resolves the contradiction by making installation simple while ensuring proper grounding is achieved.
2Object-affected harmful factors
If proper grounding is implemented for cable connections, then electromagnetic interference is reduced, but installation time and complexity increase
Solution Approach 1:
The grounding plug assembly merges the grounding function with the cable connection function into a single integrated component. The grounding electrodes, connection terminals, and insulation structure are combined in one assembly that is installed simultaneously with the cable connection. This merging resolves the contradiction by ensuring electromagnetic interference protection is achieved without requiring separate grounding installation steps, thus not increasing installation time.
3Reliability
If grounding structure is added to cable connections, then grounding reliability is improved, but device complexity increases
Solution Approach 1:
The grounding plug assembly is designed as a universal component that can be applied to multiple types of cable connections (coaxial cables, HDMI cables, and other shielded cables). The same basic structure with grounding electrodes and connection terminals serves different cable types, providing grounding reliability without requiring different complex grounding structures for each cable type. This universality resolves the contradiction by maintaining simple device design while achieving reliable grounding across applications.
