Tool-Free Pipe Socket With Angled Contact Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipe sockets for electrical installation housings require a separate tool to break out the closing wall, which is inconvenient and prone to user error.
Innovation Solution
A pipe socket design where a tube contact element is integrated with a predetermined breaking point, allowing the wall to be broken out tool-free by transferring a moment as the pipe is inserted, with the contact surface angled relative to the inner wall to increase lateral forces and break the wall, ensuring consistent and automatic ejection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate tool is used to break out the closing wall, then the wall can be broken out, but the operation becomes inconvenient and prone to user error
Solution Approach 1:
The breaking function is merged with the pipe insertion operation itself. The pipe contact element with its angled contact surface is integrated into the pipe socket structure, so that the act of inserting the pipe directly provides the breaking force through mechanical leverage, eliminating the need for a separate breaking tool.
Solution Approach 2:
The pipe insertion process itself performs the breaking function. As the pipe is inserted and contacts the angled surface of the pipe contact element, the pipe's own insertion motion generates the lateral force needed to break the wall at the predetermined breaking point, making the system self-servicing.
2Force
If the pipe contact surface is angled relative to the inner wall, then lateral forces increase to break the wall, but the structure becomes more complex
Solution Approach 1:
The pipe contact element's contact surface is angled relative to the pipe socket's inner wall, introducing a dimensional transformation. This angular geometry converts the axial insertion force into lateral breaking force through mechanical leverage, efficiently achieving wall breakage without excessive structural complexity.
3Strength
If the pipe contact element extends further into the pipe receiving section, then more moment is transmitted to break the wall, but the risk of pipe damage increases
Solution Approach 1:
The pipe contact element has different geometric properties in different regions: the contact surface is angled to transmit breaking moment, while the tip region has a reduced radius and rounded geometry to minimize stress concentration and prevent pipe damage. This localized differentiation of geometric quality optimizes both breaking efficiency and pipe safety.

Function Achieved in This Case
Enables easy, safe, and automatic removal of the break-out area without tools, ensuring the wall is always broken out when a pipe is inserted, enhancing user convenience and reducing the risk of forgetting to open the socket.
Implementation Method 1
the pipe contact element extends from the wall into the interior of the pipe receiving section and has a pipe contact surface facing the inner wall of the pipe receiving section, which is further away from the inner wall of the pipe receiving section with increasing distance from the wall, so that when a pipe is inserted into the pipe receiving section, a moment is transmitted to the breakable section of the wall

AI summary
The invention relates to a pipe fitting of an electrical installation housing for receiving one end of a pipe (3), with a pipe receiving section (4) which is open on its side intended for the insertion of the pipe (3) and closed on its other side with a wall (5), wherein the wall (5) has a predetermined breaking point (6) so that a section of the wall (5) can be broken out, characterized in that a pipe contact element (7) is attached to the breakable section of the wall (5), which is designed such that the pipe contact element (7) extends from the wall (5) into the interior of the pipe receiving section (4) and has a pipe contact surface (9) facing the inner wall (8) of the pipe receiving section (4), which is further away from the inner wall (8) of the pipe receiving section (4) with increasing distance from the wall (5).so that when a pipe (3) is inserted into the pipe receiving section (4), a moment is transferred to the breakable portion of the wall (5), so that as the pipe (3) is inserted into the pipe receiving section (4), the breakable portion of the wall (5) is broken out and finally ejected from the pipe socket. In this way, such a pipe socket is provided for an electrical installation housing, the wall of which, closing an opening in the pipe socket, can be removed easily and safely without tools.
