Fuel Line Attachment Assembly Collision Decoupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fuel lines in vehicles are prone to damage during collisions due to tight packaging constraints in the engine compartment, making it difficult to prevent impact from other displaced components.
Innovation Solution
A fuel line attachment assembly featuring a fixed portion coupled to the vehicle frame and a movable portion with a stop element, allowing the fuel line to decouple from the frame when a threshold force is applied, directing the fuel line away from potential impact zones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the fuel line is fixedly coupled to the vehicle frame to block vibration during normal use, then the stability of the fuel line is improved, but the fuel line becomes vulnerable to impact damage during collision
Solution Approach 1:
The attachment assembly transitions from a static fixed coupling to a dynamic system with movable portions that can slide along recesses. The stop element allows the assembly to maintain stability during normal operation while enabling movement during collision to redirect impact forces away from the fuel line, resolving the contradiction between stability and impact protection
2Object-affected harmful factors
If the fuel line is decoupled from the vehicle frame to protect against impact, then the fuel line protection is improved, but the fuel line becomes unstable during normal use
Solution Approach 1:
The system changes its mechanical parameters dynamically: during normal operation, the stop element maintains a fixed position providing stability; during collision, when force exceeds the threshold, the stop element allows movement to change the position and orientation parameters of the fuel line, directing impact forces away from vulnerable components
3Object-affected harmful factors
If a movable portion with stop element is added to allow decoupling during collision, then the fuel line protection is improved, but the device complexity increases
Solution Approach 1:
The attachment assembly is segmented into distinct functional portions: a fixed portion attached to the vehicle frame, a movable portion that can slide, and a stop element that controls the transition. This segmentation allows each component to perform its specific function while maintaining overall system manageability and reducing complexity compared to a completely redesign
