Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional methods are used to feed power into busbar systems, then safety requirements are met, but the process becomes time-consuming and complex
Solution Approach 1:
The device is pre-assembled with all necessary components (carrier part, feed-in brackets, cover plate, plug-and-socket devices) before installation. The feed-in brackets are pre-mounted in the carrier part with cover plate passages aligned, and plug-and-socket devices are pre-connected to the feed angles. This preliminary preparation eliminates the need for complex on-site assembly and reduces installation time while maintaining safety compliance.
Solution Approach 2:
The device is divided into modular components: carrier part, feed-in brackets, cover plate, and plug-and-socket devices. Each component serves a specific function and can be independently manufactured and assembled. The feed-in brackets are segmented to pass through both the carrier part and cover plate, creating aligned passages that simplify the connection process and reduce installation complexity.
2Object-affected harmful factors
If high IP protection class is implemented, then protection is improved, but structural complexity increases
Solution Approach 1:
The cover plate serves multiple functions simultaneously: it provides mechanical protection for the carrier part, creates IP20 protection class, and contains integrated passages that align with the feed-in brackets to enable cable passage while maintaining IP4X protection in the connector area. The cover hoods further integrate protection for both the plug-in devices and feed angles. This merging of functions reduces structural complexity compared to using separate protective enclosures.
Solution Approach 2:
The feed-in brackets are designed as multi-functional elements that simultaneously provide electrical connection, mechanical support, and cable guidance through their passages. The cover plate serves as both a protective enclosure and a structural element with integrated cable passages. This multi-functionality reduces the number of separate components needed, thereby reducing overall structural complexity while maintaining high protection classes.
3Ease of operation
If preassembly is implemented, then ease of operation is improved, but manufacturing complexity increases
Solution Approach 1:
The device is manufactured as segmented modular components (carrier part, feed-in brackets, cover plate, plug-and-socket devices) that can be independently produced using standardized processes. The feed-in brackets are manufactured with pre-formed passages, and the cover plate is manufactured with corresponding passages. This segmentation allows each component to be manufactured separately with standard tolerances, avoiding the need for complex post-manufacturing assembly operations.
Solution Approach 2:
The passages in the feed-in brackets and cover plate are pre-formed during manufacturing with precise alignment features. The plug-and-socket devices are pre-connected to the feed angles before final assembly. This preliminary preparation of alignment features and connections simplifies the final installation process, as components can be quickly assembled using standard fastening methods without requiring complex alignment procedures.
