Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical panels with daisy chain data bus configurations require manual installation of cable connections between switching devices and connectors, leading to high installation costs, wiring errors, and performance issues due to varying cable lengths.
Innovation Solution
A communication interface integrated within the electrical panel's housing, featuring a switching device and data connector, eliminates the need for cable connections by ensuring data bus continuity through a selectively switchable mechanism, reducing installation complexity and maintaining performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual cable installation is used to connect switching devices to connectors, then the data bus can be configured in daisy-chain, but installation costs increase and wiring errors become more frequent
Solution Approach 1:
The patent combines the switching device and data connector into a single integrated communication interface unit. This merging eliminates the need for separate cable connections between switching devices and connectors, thereby reducing installation complexity while maintaining data bus continuity through the integrated design.
Solution Approach 2:
The patent extracts the cable connection requirement from the system by integrating the switching device and connector into a single unit. This extraction removes the problematic manual cable installation step while preserving the essential function of data bus connectivity.
2Ease of manufacture
If cable connections are used between switching devices and connectors, then the system can be assembled, but the risk of wiring errors increases
Solution Approach 1:
By merging the switching device and data connector into one integrated communication interface, the patent eliminates multiple cable connection points that could lead to wiring errors. The integrated design ensures proper connections are made during manufacturing, reducing the risk of field wiring mistakes.
3Adaptability or versatility
If varying cable lengths are used in the data bus connections, then the panel can accommodate different configurations, but data transmission performance deteriorates
Solution Approach 1:
The integration of switching device and connector into a single communication interface unit with standardized housing dimensions ensures uniform connection lengths across all interfaces. This eliminates the performance degradation caused by varying cable lengths while maintaining configuration flexibility through the modular drawer design.
Solution Approach 2:
The patent standardizes the connection parameters by integrating components with fixed positions within the housing, ensuring consistent cable lengths. This parameter standardization maintains optimal data transmission performance while the modular architecture preserves system adaptability.
4Adaptability or versatility
If multiple separate cable connections are installed, then each device can be connected individually, but installation costs increase
Solution Approach 1:
By combining the switching device and data connector into a single integrated unit, the patent reduces the number of separate cable connections required. Each communication interface becomes a self-contained module that connects to the data bus through a single standardized interface, significantly reducing installation complexity and cost in multi-device configurations.
