Duct Connection Insert Locking Against External Loads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing installation and distribution systems face challenges in securely fixing connection devices or device inserts within ducts or housings under strong external loads, while maintaining simple and uncomplicated installation processes.
Innovation Solution
The system incorporates a separate locking element that connects to the connection device or device insert via a second connection and engages with the duct or housing via a third connection, effectively blocking movement transverse to the insertion direction and securing the first snap-in or locking connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If snap-in or latching connections are used to facilitate assembly, then ease of installation is improved, but reliability under strong external loads deteriorates
Solution Approach 1:
The connection system is divided into two independent parts: a first connection (snap-in or latching connection) for easy installation, and a separate locking element with a second connection for securing against external loads. The locking element is inserted through a separate opening and acts independently on the connection device, preventing it from becoming loose under tension or lateral forces while maintaining the simplicity of the original snap-in connection.
2Reliability
If a separate locking element is added to secure connections under external loads, then reliability is improved, but device complexity increases
Solution Approach 1:
The locking function is extracted as a separate, independent element that can be added to the connection device without modifying the existing snap-in or latching connection. The locking element is inserted through a separate opening in the duct or housing and acts independently on the connection device, preventing it from becoming loose under tension or lateral forces while maintaining the simplicity of the original connection mechanism.
3Reliability
If the duct or housing is made more rigid to prevent deformation under loads, then reliability is improved, but ease of manufacture deteriorates
Solution Approach 1:
Instead of making the duct or housing more rigid to prevent deformation, the invention applies a counteracting force through the locking element that actively prevents the connection device from becoming loose under external loads. The locking element compensates for the flexibility of the duct or housing by providing a mechanical locking action that counteracts the deforming forces, thereby maintaining connection security without requiring increased structural rigidity.

Function Achieved in This Case
This solution ensures that connection devices or device inserts remain securely fixed within the ducts or housings even under strong external loads, without requiring additional components or assembly steps, thereby enhancing the system's performance characteristics.
Implementation Method 1
complementary resilient or material-elastic areas on the connection device or on the device insert on the one hand and on the duct or housing on the other hand interact

AI summary
An installation and distribution system in which connection devices or device inserts connected via cables or contacts for electrical power supply or data transmission can be accommodated within ducts or housings, wherein the connection devices or device inserts can be inserted through openings or recesses in the duct or housing and can be locked there by means of a first snap-in or latching connection, in which complementary resilient and/or material-elastic areas on the connection device or device insert on the one hand and on the duct (or housing) on the other hand interact, wherein at least one separate locking element is provided adjacent to the respective connection device or device insert, which on the one hand can be connected to at least one connection device or device insert and which on the other hand provides at least a third connection,in which areas of the channel or housing that are complementary to the locking element interact in a form-fitting manner so that the first connection is locked.
