Evaporative Canister Integrated Port Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing evaporative emissions canister systems with quick connectors and hoses increase costs and space requirements, and introduce potential leak interfaces, which are not effectively addressed by current technologies.
Innovation Solution
An evaporative emissions canister with a monolithic body and mounting bracket that directly secures an accessory component via a female port and sleeve seal, eliminating the need for hoses and connector fittings by using a self-tapping screw to attach the accessory component to the mounting bracket.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If quick connectors and hoses are used to connect accessory components to the canister, then the system allows for flexible connections, but the cost and space requirements increase and potential leak interfaces are introduced
Solution Approach 1:
The mounting bracket is merged with the canister body as a single monolithic component, eliminating the need for separate mounting brackets and reducing the number of connection interfaces. This integration directly reduces assembly complexity while maintaining connection flexibility through the integrated port design.
Solution Approach 2:
The hose and connector fittings are extracted from the system by providing direct access ports on the canister body that allow accessory components to connect directly to the canister. This removal of intermediate components eliminates potential leak interfaces and reduces overall assembly complexity.
2Adaptability or versatility
If quick connectors and hoses are used to connect accessory components to the canister, then connections can be made, but the cost and space requirements increase
Solution Approach 1:
The mounting bracket functionality is merged into the canister body structure, eliminating the need for separate mounting bracket parts. This reduction in part quantity decreases both material costs and assembly complexity while maintaining full component connectivity through the integrated port design.
Solution Approach 2:
The hose and connector fittings are extracted from the system by providing direct access ports on the canister body. This removal of intermediate components reduces the total number of parts required, lowering both cost and space requirements while maintaining accessory component connectivity.
3Adaptability or versatility
If quick connectors and hoses are used to connect accessory components to the canister, then connections can be established, but potential leak interfaces are introduced
Solution Approach 1:
The hose and connector fittings are extracted from the system by providing direct access ports on the canister body. This removal of intermediate components eliminates potential leak interfaces at connector connections, thereby improving reliability while maintaining connection capability through the integrated port design.
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
This solution provides a more compact, cost-effective, and leak-proof interface between the evaporative emissions canister and accessory components, enhancing the system's reliability and reducing assembly complexity.
Implementation Method 1
a sleeve seal is disposed in the port, and the accessory component is mateable with the sleeve seal
Implementation Method 2
Canister systems that employ adsorbents such as activated carbon to adsorb the fuel vapor emitted from the fuel systems
Implementation Method 3
atmospheric air is introduced through the atmospheric vent port to purge the fuel vapor in the canister by desorbing fuel vapor that was adsorbed in the adsorbent
