Iris Seal Power Outlet Closure for Vehicle Console
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle power outlets with hinged covers face space constraints in vehicle consoles, leading to interference with other devices and systems, necessitating a space-saving solution that prevents dust and debris intrusion without hinged covers.
Innovation Solution
An iris-style closure system using a base ring with concentric blades and an actuator knob, where biasing members or manual operation allow the blades to transition between open and closed configurations, eliminating the need for hinged covers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If hinged covers are used to seal the power outlet, then dust and debris intrusion is prevented, but space in the vehicle console is reduced and interference with other devices occurs
Solution Approach 1:
The closure is divided into multiple concentric blades that can independently pivot about the base ring. Each blade segment can move separately to open or close the aperture, allowing the sealing function to be achieved with a more compact structure that doesn't require the bulk of a hinged cover
Solution Approach 2:
The closure transitions from a static hinged cover to a dynamic iris mechanism where blades can continuously adjust between fully open, fully closed, and intermediate positions. This dynamic structure allows the same sealing function with reduced space requirements since the blades fold concentrically when closed
2Object-affected harmful factors
If hinged covers are used to seal the power outlet, then dust and debris intrusion is prevented, but interference with other devices or systems occurs
Solution Approach 1:
By dividing the closure into multiple independent blade segments rather than a single solid hinged cover, the mechanism achieves the sealing function with a more adaptable structure that can be integrated into tighter spaces without interfering with adjacent devices or systems
Solution Approach 2:
The concentric blades are nested within each other when closed, with each blade positioned inside the radius of the previous blade. This nesting arrangement allows the entire closure mechanism to occupy minimal space and adapt to various console layouts without interfering with other components
3Volume of moving object
If iris-style closure is used instead of hinged covers, then space in vehicle console is optimized, but device complexity increases
Solution Approach 1:
The closure mechanism is designed to be self-actuating through the interaction of the actuator knob with the blades and biasing members. When the actuator knob is rotated, it automatically drives the blades to open or close without requiring additional motors, sensors, or control systems, thereby reducing overall device complexity despite the intricate blade arrangement
Solution Approach 2:
The complex electrical or motorized closure systems are replaced with a purely mechanical iris mechanism driven by a simple actuator knob. The mechanical advantage provided by the lever arms and biasing members eliminates the need for complex control electronics, actuators, or power consumption, simplifying the overall system despite the mechanical intricacy of the blades
4Device complexity
If iris-style closure is used instead of hinged covers, then hinged covers are eliminated, but manufacturing complexity increases
Solution Approach 1:
The closure is manufactured as multiple separate blade segments rather than a single integrated hinged cover piece. Each blade can be manufactured independently using standard machining or molding processes, then assembled around the base ring. This segmentation allows for simpler individual component manufacturing compared to creating a complex hinged cover assembly
Solution Approach 2:
The base ring serves multiple functions: it provides the pivot point for all blades, acts as the structural support for the entire closure mechanism, and serves as the mounting interface to the power outlet housing. This multi-functionality reduces the total number of parts that need to be manufactured and assembled, offsetting the complexity of the segmented blade structure

AI summary
A power outlet seal for a vehicle includes an iris seal and an actuator knob configured to translate the iris seal between an opened configuration and a closed configuration. The iris seal is defined by a plurality of blades disposed concentrically on a base ring. The actuator knob includes an actuator ring for biasing the plurality of blades to the opened configuration. One or more resilient members are disposed to bias the plurality of blades to the closed configuration. Power outlet seal assemblies including the power outlet seal, and console or trim pieces including the power outlet seal assemblies, are disclosed.
