Front Storage Drawer Module for Safe EV Frunk Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicles face challenges in accessing storage space due to limited rear gate opening capabilities in confined spaces and restricted access to the front under-hood area, particularly in electric vehicles where high voltage components are a safety concern.
Innovation Solution
The design incorporates a retractable rear gate and a front storage module with actuators and control units that allow the rear window and rear gate to move within a cavity, and a drawer system at the front that can extend partially from the vehicle body, enabling accessible storage without exposing users to high voltage components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the rear gate is designed to swing up and away from the vehicle, then the rear cargo space is accessible, but the vehicle requires large space above and behind it which is not available when parking in confined spaces
Solution Approach 1:
The rear gate transitions from a vertical swing motion (requiring space above the vehicle) to a horizontal sliding motion along rails (requiring space alongside the vehicle). This dimensional change allows the gate to open in confined spaces where vertical clearance is limited, such as residential garages and small parking lots.
Solution Approach 2:
The gate system incorporates movable components including sliding rails and a retractable window that can move independently. The window slides within the gate assembly, and the entire gate slides along external rails, creating a dynamic system that adapts to limited space constraints while maintaining cargo access.
2Object-affected harmful factors
If the hood is restricted to protect high voltage components in electric vehicles, then user safety is improved, but access to front storage space is lost
Solution Approach 1:
The storage function is extracted from the traditional under-hood space and relocated to a dedicated front storage module positioned behind the hood. This allows the hood to remain closed for safety while providing accessible front storage through a separate mechanism that does not require hood opening.
Solution Approach 2:
A drawer actuator serves as an intermediary mechanism between the user and the storage contents. The actuator can be controlled through the vehicle's existing control interfaces (buttons, switches, or mobile device), allowing users to access front storage without physically opening the hood or exposing themselves to high voltage areas.
3Ease of operation
If the rear gate is made retractable within a cavity, then access to cargo space is improved in tight spaces, but the device complexity increases
Solution Approach 1:
The gate system is divided into separate functional segments: the main gate body, the window assembly, and the drawer unit. Each segment can move independently along dedicated rails or tracks, allowing for controlled operation of individual components rather than moving the entire assembly as one unit.
Solution Approach 2:
The drawer actuator is designed to perform multiple functions: it can extend the drawer for storage access, retract it for closure, and potentially assist in the overall gate operation. This multi-functionality reduces the need for separate mechanisms, thereby managing complexity while achieving multiple operational goals.
