Socket Assembly Tool-Free Cover Frame Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing socket arrangements for device installation trunking face difficulties in precise tool-free positioning of cover frames and lack security against unauthorized removal, either requiring tools for assembly or increasing assembly effort.
Innovation Solution
A socket arrangement with a snap-in connection between the cover frame and socket unit, featuring retaining rails and guide elements for easy installation and secure locking, ensuring the cover frame cannot be removed without tools, utilizing a pre-wired electrical mains socket and color-coded ring for visual labeling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cover frame is clamped to achieve secure positioning, then the cover frame is firmly fixed, but exact positioning becomes more difficult and requires tools
Solution Approach 1:
The socket unit is designed to automatically guide and position the cover frame through integrated guide elements (protrusions and recesses) that self-align during the snapping process, eliminating the need for tools or complex positioning mechanisms while ensuring exact placement
Solution Approach 2:
The connection system is divided into separate functional elements: guide elements for positioning, snap-in elements for securing, and release mechanisms for removal. This segmentation allows each element to perform its specific function independently, achieving secure fixation without complicating the positioning process
2Ease of operation
If tool-free assembly is used to simplify installation, then assembly effort is reduced, but protection against unauthorized removal is lost
Solution Approach 1:
The connection strength parameter is dynamically controlled through the snapping mechanism that requires specific force thresholds for both attachment and release. The latching elements engage at a certain force level to prevent accidental removal, while the release mechanism is designed to disengage at a different force threshold, providing security against unauthorized removal while maintaining ease of legitimate assembly and disassembly
Solution Approach 2:
Latching elements serve as intermediary components between the cover frame and socket unit, providing a mechanical interlock that prevents unauthorized removal. These elements engage automatically during tool-free assembly but require deliberate action (insertion tool or sufficient force) to release, thus mediating between ease of assembly and security requirements
3Reliability
If additional fastening elements are used to secure the cover frame, then protection against unauthorized removal is improved, but assembly effort increases and tools are required
Solution Approach 1:
Multiple functions are merged into integrated components: the guide elements also serve as positioning features, the snap-in elements provide both securing and positioning, and the latching elements combine security function with automatic engagement. This merging eliminates the need for separate fastening elements, reducing device complexity while maintaining security
Solution Approach 2:
The snap-in elements and latching elements are designed to perform multiple functions: guiding the cover frame into position, securing it firmly, preventing unauthorized removal, and enabling controlled release. This multi-functionality reduces the total number of components needed while achieving all required objectives

AI summary
The arrangement has a socket unit (2) that is provided with socket base, socket receptacle (4) and a cover frame, such that latching connection to socket unit is flexible. The locking connection to socket unit is integrally formed through cover frame, when locking elements are engaged with socket receptacle corresponding to locking mount portion (12). The locking connection to socket unit is integrally formed through socket receptacle, when locking elements are engaged with cover frame corresponding to locking mount portion. An independent claim is included for device channel.
