Coolant Conduit Fixing Assembly with Overmolded Ring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for fixing coolant supply pipes in motor vehicles are complex and time-consuming due to the difficulty in aligning clamps with circumferential marks, making it challenging to achieve a simple and reliable installation, especially in the vicinity of the engine.
Innovation Solution
A fixing assembly comprising a support plate with a ring overmolded onto the coolant supply conduit and a fixing lug that extends parallel to the conduit's axis, allowing for a latching movement onto the support plate, simplifying the installation process and providing a secure hold with integrated, economical fastening means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixing clips are used with circumferential marks on the conduit, then the conduit can be fixed to the support plate, but the assembly process becomes complex and time-consuming due to alignment difficulties
Solution Approach 1:
The ring is pre-formed with an integrated fixing tab at the correct position and orientation before installation. This preliminary preparation eliminates the need for alignment marks and complex positioning during assembly, as the fixing tab is already in its final functional position parallel to the conduit axis
Solution Approach 2:
The fixing tab is merged with the ring to form a single integrated component. This combination eliminates the need for separate alignment marks and fixing elements, simplifying both the device structure and the assembly process while maintaining reliable fixation
2Reliability
If fixing clips are used with circumferential marks on the conduit, then the conduit can be fixed to the support plate, but the assembly time increases due to difficult alignment in the vicinity of the engine
Solution Approach 1:
The ring is pre-formed with an integrated fixing tab at the correct position and orientation before installation. This preliminary preparation eliminates the need for alignment marks and complex positioning during assembly, as the fixing tab is already in its final functional position parallel to the conduit axis
Solution Approach 2:
Instead of marking the conduit and requiring alignment during assembly, the invention inverts the approach by pre-positioning the fixing tab on the ring itself. The tab's orientation parallel to the conduit axis is established during ring formation, reversing the traditional sequence and eliminating alignment time
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
The solution enables faster and simpler installation of coolant supply pipes by pre-positioning the ring and fixing lug, reducing assembly time and improving holding security, even under vehicle movement, while minimizing material usage.
Implementation Method 1
The ring is formed by overmolding onto the supply conduit
