Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bridging devices for electrical line protection devices of modular type on rails lack universality, as they cannot adapt to varying configurations of modular protection devices due to differences in bridging levels and spatial periodicities, requiring multiple devices for different installations.
Innovation Solution
A configurable bridging device with a base bar and modular cassettes that can be easily exchanged, allowing for adjustable bridging levels and spatial periodicity, enabling connection to all modular electrical devices with a single reference system, using U-shaped conductive jumpers and flexible clamps for safe electrical contact.

Engineering Contradiction Analysis
1Adaptability or versatility
If traditional bridging combs with fixed conductive bars are used, then the structure is simple and easy to manufacture, but the device cannot adapt to varying configurations of modular protection devices with different bridging levels and spatial periodicities
Solution Approach 1:
The bridging device is divided into a fixed bar component and interchangeable cassette modules. Each cassette is a self-contained unit with specific bridging levels and conductive bar configurations. This segmentation allows the system to adapt to different device configurations by simply changing cassettes rather than redesigning the entire bridging device, thus improving versatility while keeping the base structure simple.
Solution Approach 2:
The standardized bar with uniform spacing provisions serves as a universal base that can accommodate multiple types of cassettes. The cassettes are designed with standard mounting interfaces that match the bar's spacing, allowing a single bar design to support various bridging configurations through cassette interchangeability. This universal interface approach enables one base structure to serve multiple functions.
2Adaptability or versatility
If multiple fixed bridging devices are manufactured for different configurations, then each device can be optimized for its specific use, but the quantity of devices and inventory complexity increases
Solution Approach 1:
Instead of manufacturing complete bridging devices for each configuration, the invention segments the system into a universal bar and interchangeable cassettes. The cassettes contain the configuration-specific elements (conductive bars at specific levels), while the bar remains standardized. This reduces the number of complete devices needed, as one bar can support multiple configurations through cassette swaps.
Solution Approach 2:
The cassette modules are designed to be easily removed and replaced based on configuration needs. When a change in bridging configuration is required, the old cassette is discarded (or stored for later use) and a new cassette is installed. This approach allows rapid reconfiguration without manufacturing entirely new devices, reducing overall device quantity requirements.
3Adaptability or versatility
If modular cassettes with interchangeable components are introduced, then adaptability to different configurations is improved, but the ease of operation and installation is reduced due to additional assembly steps
Solution Approach 1:
The cassettes are pre-assembled units with conductive bars, insulation, and mounting features already configured before reaching the installation site. The connection means (screws, clips, or other fastening mechanisms) are pre-positioned on the cassettes. This preliminary assembly reduces on-site installation complexity, as electricians only need to attach the complete cassette to the bar rather than assembling multiple components during installation.
Solution Approach 2:
Multiple functional elements are merged into the cassette module: conductive bars, insulation material, mounting interfaces, and connection mechanisms are all integrated into a single replaceable unit. This merging simplifies the installation process by reducing the number of separate assembly steps, while still providing the adaptability of modular configuration changes.

AI summary
The device has a rod (1) constituted of material case comprising phase conducting sills and a neutral conducting sill isolated between each other. A connection unit connects connection studs (5, 5', 5'') to the phase conducting sills or neutral conducting sill. The rod is arranged between electric apparatuses and cassettes (2, 2', 2''). The rod has coaxial or transversal openings (7') for passage of the connection studs. The cassettes comprise different-sized end lugs (9, 10) for immediate mounting of the cassettes on the rod.
