Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If bus systems are routed outside of electrical components, then access to the bus system is facilitated and installation is simplified, but connection security and reliability for power currents may be compromised
Solution Approach 1:
The connection system is divided into modular plug-in arrangements that can be individually connected to each electrical component. Each plug-in arrangement contains a clamping spring mechanism that securely holds the busbar, providing reliable connection while maintaining external routing for easy access and installation.
2Productivity
If modular plug-in arrangements with clamping springs are used, then rapid installation and easy reconfiguration are enabled, but device complexity increases
Solution Approach 1:
Multiple functional elements are merged into a single integrated plug-in arrangement: the housing, clamping spring, contact means, and busbar connection points are combined into one modular unit. This reduces the number of separate components to be assembled while maintaining the rapid installation and reconfiguration capabilities.
3Reliability
If contact means with supporting arches and multiple solder feet are used, then current-carrying capacity and stability are increased, but manufacturing complexity increases
Solution Approach 1:
The contact means design parameters are optimized by adding supporting arches and multiple solder feet, which increase the current-carrying capacity and mechanical stability. The supporting arches distribute mechanical stresses and provide additional mounting points, while multiple solder feet increase the effective contact area and current distribution.

AI summary
The present invention relates to a series module arrangement with a bus system and series modules, which are arranged one alongside another in a row arrangement direction on a mounting base, particularly a support rail, and each have an electronics housing with a recess, in which at least one circuit board is arranged. The bus system comprises busbars running outside the electronics housing, at least one busbar being electrically connectable to the circuit board of one of the series modules via a plug-in arrangement. The plug-in arrangement comprises a clamping spring and can be reversibly inserted into the electronics housing by being pushed from the exterior in a joining direction through the recess of the electronic housing, and therefore the clamping spring is electrically connected to the circuit board, and the busbar can be inserted from the exterior into the plug-in arrangement in such a manner that it electrically contacts the clamping spring.
