Heated Fluid Connector Ramp Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing connectors for heatable fluid lines, particularly those used in motor vehicles to transport urea, face manufacturing complexities and risks of damage due to the need for auxiliary tools to deflect heating media at angled outlets, which can lead to leaks and production inefficiencies.
Innovation Solution
A connector design featuring a permanently integrated ramp element within the through-channel, which guides the heating medium from the through-channel to the angled heating medium outlet channel using a smooth guide surface, eliminating the need for external tools and minimizing material usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a through-channel runs essentially in a straight line and the heating means is led out laterally, then the connector structure is simple, but production becomes complex and prone to failure due to the need for auxiliary tools to deflect the heating medium
Solution Approach 1:
The heating medium outlet channel is arranged at an angle α (20°-80°) relative to the longitudinal axis of the through-channel, creating a three-dimensional flow path that eliminates the need for lateral deflection tools during production. This angular arrangement allows the heating medium to be guided directly into the outlet channel from the front, simplifying the manufacturing process.
2Manufacturing precision
If an auxiliary tool is used to deflect the heating medium into the heating medium outlet channel, then the heating medium can be directed properly, but the production process becomes complex and the risk of damage increases
Solution Approach 1:
The ramp element is pre-integrated into the connector structure during manufacturing, creating a permanent guide surface that automatically directs the heating medium into the outlet channel. This preliminary structuring eliminates the need for auxiliary deflection tools during the production process, reducing both complexity and damage risk.
3Temperature
If the heating medium outlet channel is at an angle to the through-channel, then the heating can be more effective, but auxiliary tools are required to insert the heating medium
Solution Approach 1:
The ramp element serves as an intermediary component that mediates between the straight through-channel and the angled heating medium outlet channel. Its guide surface smoothly transitions the heating medium from the axial direction into the angled outlet channel, making insertion easy while maintaining effective heating geometry.
