Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electrical power distribution systems for modular devices, such as circuit breakers, are inefficient in terms of compactness and require significant space for signaling and control systems, which complicates wire-to-wire connections and overall system size.
Innovation Solution
A power distribution device with a compact design that integrates signaling and control processing systems alongside the electrical connection device, utilizing a communication bus and elastic connection terminals, allowing for a more efficient use of space by arranging phase and neutral terminals on each pitch of the distributor, and incorporating a movable part for the processing device to optimize space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If signaling and control processing systems are placed separately from the power distribution device, then wire-to-wire connections can be established, but the overall system size and space requirements increase significantly
Solution Approach 1:
The patent combines the signaling and control processing systems with the power distribution device into a single integrated unit. The processing device is housed within the same casing as the power bars and connection means, eliminating the need for separate housing and reducing overall system volume while maintaining full functionality for both power distribution and control signaling.
Solution Approach 2:
The integrated device performs multiple functions simultaneously: it distributes electrical power through the power bars and neutral bar, processes control signals through the integrated processing device, and provides communication interfaces. This multi-functional design eliminates the need for separate dedicated spaces for control systems.
2Ease of manufacture
If traditional separate housing is used for power distribution and control systems, then functional separation is maintained, but the height and space requirements double
Solution Approach 1:
The patent transitions from a vertical stacking arrangement (separate housings one above the other) to a horizontal integration arrangement within a single casing. The processing device is positioned horizontally alongside the power distribution components, utilizing the same vertical space and reducing overall height by approximately half while maintaining functional separation through internal compartmentalization.
3Productivity
If elastic connection terminals are used on each pitch, then connection efficiency improves, but device complexity increases
Solution Approach 1:
The patent employs elastic connection terminals of the same type (quarter-turn terminals) uniformly across all phase and neutral positions on each pitch. This homogeneous approach simplifies the connection process and maintains consistent performance while the repetitive modular pattern actually reduces overall complexity compared to mixed connection types.
Solution Approach 2:
The connection system is divided into modular pitches, each containing a complete set of phase and neutral terminals. This segmentation allows for standardized, repeatable connection units that simplify installation and maintenance while improving connection efficiency through consistent elastic terminal design across all modules.
