Vehicle Front Trunk Access Structure With Cabin Transfer Port
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing vehicle trunk structures require users to stop and open the bonnet every time to access the trunk, which is inconvenient and may lead to issues like smell leakage and package slippage into the cabin.
Innovation Solution
A vehicle front part structure with a front trunk and a communication portion that allows packages to be housed from the vehicle cabin side, featuring tilted inner surfaces and fragile portions to absorb impact, preventing package movement and entry into the cabin during collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the trunk is accessed by opening the bonnet from outside the vehicle, then the trunk can be opened, but user convenience deteriorates because the user must stop the vehicle and exit to access the trunk
Solution Approach 1:
The trunk access system is segmented into two independent access paths: external access via bonnet opening and internal access via communication portion from the vehicle cabin. This allows users to choose the more convenient internal access method while preserving the external access capability.
Solution Approach 2:
A communication portion is introduced as an intermediary structure connecting the vehicle cabin interior to the trunk. This intermediary allows packages and items to be transferred from the cabin to the trunk without requiring bonnet opening, thus eliminating the need to exit the vehicle for trunk access.
2Ease of operation
If the trunk is directly connected to the vehicle cabin, then easy access is achieved, but smell leakage from the trunk toward the vehicle cabin occurs
Solution Approach 1:
The lid is extracted as a separate controllable element that can independently open or close the communication portion between the cabin and trunk. When closed, it effectively extracts the potential污染源 (smell source) from the cabin environment while maintaining the structural connection for package transfer.
Solution Approach 2:
The lid provides preliminary protection by closing the communication opening before any potential smell leakage can occur. This preliminary action prevents the harmful effect (smell leakage) from manifesting in the first place, rather than attempting to remove or neutralize smells after they have leaked.
3Ease of operation
If the trunk is directly connected to the vehicle cabin, then package transfer is simplified, but package slippage to the vehicle cabin side cannot be prevented
Solution Approach 1:
The lid is extracted as a separate controllable barrier that can independently close the communication opening. This extracted element provides reliable containment for packages during transfer operations, preventing slippage into the cabin while maintaining the structural connection for convenient package access.
Solution Approach 2:
The lid acts as a flexible barrier that can open to allow package transfer and close to prevent package slippage. This thin film-like structure effectively separates the cabin and trunk spaces when closed, providing reliable package containment without requiring complex rigid sealing mechanisms.
4Ease of operation
If the inner bottom surface of the front trunk is tilted to facilitate package movement, then package transfer to the front trunk is easier, but a corner is formed that breaks and bends under impact load
Solution Approach 1:
The tilted inner bottom surface is applied locally only to the extent needed to facilitate package movement, rather than extending it throughout the entire trunk structure. This localized application maintains the strength of the overall structure while providing the necessary package transfer assistance in the critical area.
Solution Approach 2:
Instead of tilting the entire trunk bottom surface (excessive action), only the necessary portion is tilted to achieve adequate package movement. This partial action provides sufficient functionality for package transfer while preserving the structural integrity and impact resistance of the full trunk assembly.
5Object-affected harmful factors
If fragile portions are provided in the wall portions of the front trunk, then impact force is absorbed and cabin protection is improved, but the structural strength is reduced
Solution Approach 1:
Fragile portions are pre-positioned in the wall structure to act as impact absorption zones. These predetermined weak points are designed to fail in a controlled manner during collision, absorbing impact energy before it can reach the cabin, thus providing beforehand cushioning against harmful impact forces.
Solution Approach 2:
The fragile portions convert the potentially harmful effect of structural rigidity (which would transmit impact force to the cabin) into a beneficial impact absorption mechanism. By intentionally creating controlled weakness points, the structure transforms impact energy into deformation of these fragile portions, protecting the cabin from the full force of collisions.
