Quick Connector With Angled Latching Slots For Hose Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hose/duct connector systems for air induction systems in automotive engines require custom machinery for assembly, are costly, and can lead to misconnections due to lack of feedback, noise issues, and increased complexity, affecting NVH targets and customer perception.
Innovation Solution
A three-piece quick connector system with angled latching slots and flanges that provides haptic feedback upon locking, allowing for easy assembly without special tools or machines, and can be integrated into conduits, reducing parts and assembly complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If custom machines are used to assemble plug connectors to conduits, then assembly precision is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The connector is divided into separate components (body, lid, locking mechanism) that can be manufactured independently using standard molding processes, then assembled without custom machinery. This segmentation allows each part to be produced with conventional equipment while maintaining high assembly precision through feature-based alignment.
Solution Approach 2:
The connector incorporates self-aligning features such as angled latching slots and complementary geometric profiles that automatically guide proper positioning during assembly. The locking mechanism self-actuates through spring-loaded engagement, eliminating the need for externally controlled assembly machines.
2Ease of operation
If clamps are used to connect conduits, then ease of operation is improved, but additional tools and packaging complexity are required
Solution Approach 1:
The connector integrates the sealing, locking, and alignment functions into a single unified component that attaches directly to the conduit ends. This merging eliminates the need for separate clamps, fasteners, and packaging materials, while maintaining ease of operation through direct hand assembly.
3Device complexity
If plug connectors are used without feedback mechanisms, then device complexity is reduced, but reliability of connection decreases
Solution Approach 1:
The connector incorporates audible click feedback through spring-loaded locking elements that engage with distinct mechanical resistance and sound. Visual feedback is provided through aligned features on the connector body and lid that indicate proper positioning. This feedback ensures reliable connection without adding complex electronic or sensor systems.
4Reliability
If plug connectors are designed for secure locking, then connection reliability is improved, but rattle noises affecting NVH targets occur
Solution Approach 1:
The connector incorporates elastomeric damping elements and flexible sealing lips that absorb vibration and dampen mechanical impacts. These compliant materials reduce rattle noises generated by the locking mechanism while maintaining secure mechanical engagement and connection reliability.

AI summary
Method and system are provided for a quick connector for coupling conduits. The quick connector comprises a first piece including a first slot group, a second piece including a second slot group and a first protrusion group counterpart to the first slot group, and a third piece including a second protrusion group counterpart to the second slot group, where each slot of the first slot group angles in a first direction, and each slot of the second slot group angles in an opposing, second direction. In one example, the quick connector may include a locking mechanism and a feedback system.
