Electric Installation Device Hook Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical installation devices require complex ergonomic handling for changing the hook's position and establishing electrical contact with busbars, due to their intricate design, which complicates the mounting and removal processes.
Innovation Solution
The housing features a channel for guiding the receptacle, which includes latching means and an elastic element to facilitate easy positioning and secure contact of the hook with the busbar, allowing for simple conversion of the output side and safe electrical connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the hook is held in a fixed housing with guide-holding rails, then the hook can be securely clamped and held in position, but the handling when connecting the hook and housing becomes ergonomically complex
Solution Approach 1:
The housing is divided into a fixed part and a movable part that can be displaced relative to each other along the longitudinal axis. The hook is held in the movable part, which can be moved between a clamped position (secured to housing) and a release position (disengaged from housing). This segmentation allows simple removal and installation of the hook without complex guide-holding rails, resolving the contradiction between secure clamping and ease of operation.
2Manufacturing precision
If the receptacle is designed with guide-holding rails for hook positioning, then the hook position is precisely controlled, but the structural design of the housing becomes complex
Solution Approach 1:
The housing is segmented into fixed and movable parts that slide relative to each other along the longitudinal axis. The movable part contains the receptacle and hook, allowing precise positioning through the controlled displacement between parts rather than through complex internal guide-rail structures. This reduces housing structural complexity while maintaining positioning precision.
Solution Approach 2:
The movable part of the housing serves multiple functions: it holds the receptacle, guides the hook positioning through its own displacement along the longitudinal axis, and provides the clamping mechanism when engaged with the fixed part. This multi-functionality eliminates the need for separate guide-holding rails, reducing overall structural complexity while maintaining positioning precision.
3Adaptability or versatility
If the hook is rotatably guided in the installation device, then the outgoing side can be changed, but the receptacle design becomes more complex
Solution Approach 1:
The receptacle is designed to be movable along the longitudinal axis of the housing rather than rotatably guided. By moving the entire movable part of the housing containing the receptacle along the longitudinal axis, the hook's effective position and orientation relative to the busbar can be changed. This linear displacement approach is simpler than rotational guidance mechanisms, achieving adaptability while reducing receptacle design complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enables quick and uncomplicated change of the output side and ensures reliable electrical contact, with the elastic element allowing easy insertion and removal of the receptacle, reducing ergonomic complexity and enhancing usability.
Implementation Method 1
the receptacle in the region cooperating with the channel has an elastic element which moves the hook against the busbar in the first position and in the second position
Implementation Method 2
the receptacle has latching means for latching with the housing in the first and second Having position in the longitudinal direction of the channel

AI summary
The invention relates to an electrical installation device (1) with a housing (7) and at least one hook (8, 9) on a rear side of the installation device (1), wherein the installation device (1) can be attached to a busbar (2) by means of the hook (8, 9), wherein the hook (8, 9) can be moved from a first position to a second position opposite to it in order to change an output side of the installation device (1), and wherein the hook (8, 9) is held in a receptacle (10, 22) and can be connected to a busbar (38) of the installation device (1).In such a device, according to the invention, the housing (7) has a channel (35) for the receptacle (10, 22), wherein the receptacle (10, 22) is guided in the longitudinal direction of the channel (35) when inserted into the housing (7) in the first position and when removed from the housing (7) from the first position, as well as when inserted into the housing (7) in the second position and when removed from the housing (7) from the second position, and the receptacle (10, 22) is positioned laterally in both positions by means of the channel (35), and the receptacle (10, 22) has locking means (20, 28) for locking with the housing (7) in the longitudinal direction of the channel (35) in both positions, and the receptacle (10, 22) has an elastic element (21, 32) in the area interacting with the channel (35), which in the first position and in the second position forms the hook (8, 9) moved against the conductor rail (38).With a simple housing design, such an installation device can be easily modified with regard to the arrangement of the hooks and thus with regard to the power output side of the installation device.
