Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electromagnetic switching devices with connection-side accessories are complex in terms of production and handling, requiring multiple connection methods and special instructions for different configurations.
Innovation Solution
The design incorporates standardized guide and holding recesses/projections, latching cams/hooks on the switching device and accessories, allowing for simple adaptation and combination of accessories such as protective covers and cable terminal blocks, with features like adjustable protective cover positioning and finger protection caps, enabling flexible configuration without special instructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple connection methods and special instructions are provided for different accessory configurations, then the switching device can accommodate various configurations, but the production and handling complexity increases
Solution Approach 1:
The patent implements universal guide and holding recesses/projections that can accommodate multiple accessory types (protective covers, cable terminal blocks, finger protection caps) using the same connection mechanism. The standardized interface allows a single switching device housing to work with various accessories without requiring different connection methods or special instructions, thereby reducing production and handling complexity while maintaining configuration flexibility.
Solution Approach 2:
The connection system is segmented into standardized modular components: guide recesses in the housing, guide projections on accessories, separate latching cams, and independent latching hooks. This segmentation allows each component to be manufactured independently and assembled in a consistent manner, simplifying production processes and reducing the complexity of handling different accessory configurations.
2Device complexity
If standardized guide and holding recesses/projections with latching mechanisms are used, then the production and handling is simplified, but the adaptability to different accessory requirements may be limited
Solution Approach 1:
The standardized guide and holding recesses/projections with latching mechanisms serve multiple accessory types simultaneously. The same connection interface accommodates protective covers, cable terminal blocks, and finger protection caps, demonstrating universal applicability that simplifies production and handling while maintaining adaptability to different accessory requirements.
Solution Approach 2:
The latching mechanism incorporates dynamic elements including spring-loaded latching hooks and movable latching cams that can engage with different accessory configurations. The spring clips with latching hooks can elastically deform to accommodate variations in accessory positioning, while the latching cams can rotate to engage or disengage from corresponding recesses, providing adaptive capability within the standardized connection framework.

AI summary
The invention relates to a switching device with a switching device housing, having first guiding and supporting recesses on the connecting side and at least one first detent cam that points away from the front face with a first detent surface. A protective cover which is designed as an accessory and which consists of two lateral protective walls and a front face protective wall that connects said lateral walls is equipped with at least one first detent hook, which points towards the front face protective wall with a second detent surface and which can be connected to the first detent cam, on the protective cover end face that points towards the switching device. A cable clamping block is equipped with second guiding and supporting formations that correspond to the first guiding and supporting formations and with at least one resiliently arranged third detent hook, which points towards the front face with a third detent surface and which can be connected to the first detent cam, on the cable clamping block rear wall that points towards the switching device. The cable clamping block is equipped with at least one second detent cam, the position and shape of which corresponds to the first detent cam and which can be connected to the first detent hook, on the front wall that points away from the switching device.
