Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical multiple distributors lack flexibility and require multiple housing variants for different applications, including options with and without EMC shielding, leading to increased storage and production costs.
Innovation Solution
A modular electrical multiple distributor with an inner housing featuring a distribution system, electromagnetic shielding, and a protective device against moisture, allowing optional connection of shielded cables or plug connectors, and featuring a receiving contour and clamping device for shielding lines, enabling flexible use and reduced part requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple housing variants are provided for different applications (with and without EMC shielding), then adaptability to different applications is improved, but device complexity and storage requirements worsen
Solution Approach 1:
The patent applies universality by designing a single housing that can accommodate multiple connection types (cable outlets and plug connectors) and shielding configurations through optional components. The housing includes receiving contours and clamping devices that work with both shielded and unshielded cables, eliminating the need for separate housing variants for different applications.
Solution Approach 2:
The patent segments the housing into functional components: the main housing structure, optional electromagnetic shielding layers, and configurable connection positions. This segmentation allows the same housing to be configured for different applications by selectively installing shielding and connection types, rather than requiring entirely different housing variants.
2Object-affected harmful factors
If electromagnetic shielding is always provided, then EMC shielding performance is improved, but device complexity and production costs worsen
Solution Approach 1:
The patent makes the shielding dynamic by providing it as an optional component that can be installed or removed based on application requirements. The housing includes receiving contours and clamping devices for shielding that are integrated into the design but do not require permanent installation, allowing the shielding configuration to adapt to specific EMC requirements without always being present.
3Adaptability or versatility
If different housings are provided for connecting cable outlets and plug connectors, then adaptability to different connection types is improved, but storage costs and production costs worsen
Solution Approach 1:
The patent designs the housing with universal connection capabilities by incorporating both cable outlet receiving contours and plug connector mounting positions within the same housing structure. The receiving contours and clamping devices are designed to accommodate different connection types without requiring different housing variants, thereby reducing storage and production costs while maintaining adaptability.
