Vehicle Hood Connecting Rod for Frunk Lid Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric vehicles with independent frunk lids face complex opening and closing operations and lack an impact absorption space when the vehicle hood contacts the frunk, leading to reduced Euro NCAP pedestrian protection scores.
Innovation Solution
A front storage apparatus that operatively connects the frunk lid to the vehicle hood using a connecting rod, converting the pivotal motion of the vehicle hood into the frunk lid's motion, ensuring easy opening and closing while maintaining sealability and impact absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the frunk lid is removed and the vehicle hood directly covers the frunk opening, then the structure is simplified, but the impact absorption space is lost and Euro NCAP pedestrian protection score is lowered
Solution Approach 1:
The front closure system is segmented into two independent operable components: the vehicle hood and the frunk lid. This allows the frunk lid to remain as a separate operable component that can provide impact absorption space while maintaining structural simplification compared to a fully integrated hood system.
Solution Approach 2:
The frunk lid acts as an intermediary element between the vehicle hood and the frunk opening. It provides the necessary impact absorption space and sealing function while allowing the hood to remain structurally simple and independently operable.
2Ease of operation
If the frunk lid operates independently from the vehicle hood, then the frunk can be accessed, but the opening operation becomes complex with multiple release levers
Solution Approach 1:
The opening operations of the vehicle hood and frunk lid are merged into a single coordinated action. When the hood is opened, the connecting rod automatically transfers this motion to the frunk lid, causing it to open simultaneously without requiring separate release levers or complex manual operations.
Solution Approach 2:
The frunk lid opening operation is made self-service through the connecting rod mechanism. The hood's opening motion automatically drives the frunk lid to open through the mechanical linkage, eliminating the need for additional release mechanisms or manual intervention for the frunk lid.
3Device complexity
If the vehicle hood is closed directly on the frunk opening, then the structure is simplified, but no impact absorption space is secured
Solution Approach 1:
The closure system is divided into two segments: the vehicle hood and the frunk lid. This segmentation creates a buffer zone (impact absorption space) between the hood and the frunk opening, allowing the hood to close without directly contacting the frunk structure while maintaining a simple overall closure system.
Solution Approach 2:
The frunk lid serves as an intermediary component that maintains the necessary gap between the vehicle hood and the frunk opening. It provides the structural separation needed for impact absorption while keeping the closure mechanism simple and directly operable.
