Vehicle Trunk Board Hook Structure for Vibration-Stable Cargo Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional trunk structures experience abnormal noise and potential damage due to vibration during vehicle travel, as goods and trunk boards move together, and lack flexibility in layout to accommodate varying cargo needs.
Innovation Solution
A trunk structure with a hook member that can be switched between engaged and non-engaged states, locking the cargo net to the trunk board and restraining the trunk board's movement, while allowing for flexible arrangement changes by releasing the engagement, thus preventing vibration-induced noise and damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the hook member is locked to the trunk board to fix goods during vehicle travel, then the retainment performance of goods is improved, but the trunk board cannot be freely repositioned or flipped, reducing layout flexibility
Solution Approach 1:
The hook member is designed to be detachably engaged with the engaged portion on the interior member, allowing it to switch between a fixed engaged state (when goods need to be retained) and a detached state (when layout flexibility is needed). This dynamic capability resolves the contradiction by enabling the system to adapt its degree of fixation based on operational requirements.
Solution Approach 2:
The fixation system is segmented into separate components: the hook member attached to the trunk board and the engaged portion on the interior member. This segmentation allows the hook member to be independently engaged or disengaged, enabling flexible configuration changes while maintaining secure fixation when needed.
2Object-affected harmful factors
If the trunk board is fixed to prevent movement, then vibration-induced noise and damage are reduced, but the ability to change trunk board arrangement for different cargo configurations is lost
Solution Approach 1:
The engagement between the hook member and engaged portion can be dynamically adjusted between engaged and disengaged states. When engaged, the trunk board is fixed to prevent vibration-induced noise and damage. When disengaged, the trunk board can be freely repositioned or flipped to accommodate different cargo configurations, thus resolving the contradiction between stability and adaptability.
3Stability of the object's composition
If the hook member is permanently locked to the interior member, then movement of the trunk board is completely restrained, but the cargo net cannot be easily removed or repositioned
Solution Approach 1:
The system is segmented into the hook member (attached to trunk board), the engaged portion (on interior member), and the cargo net. The cargo net can be independently removed from the hook member without affecting the engagement between the hook member and the engaged portion. This segmentation allows the cargo net to be easily removed or repositioned while the trunk board remains stably fixed through the engaged hook member.

AI summary
A trunk structure for a vehicle improves retainment performance of goods to a vehicle body in a cargo net, and improves flexibility of the layout of a trunk board. The trunk structure includes a trunk board, a hook member attached to the trunk board to which a cargo net covering goods can be locked, an interior member which constitutes an inside surface of a trunk, and an engaged portion of the interior member which the hook member can engage, the engaged portion restraining movement of the trunk board in an up-down direction when the engaged portion is engaged with the hook member. The hook member is switchable between an engaged state where the hook member engages the engaged portion and a non-engaged state where the engagement is released, and retains the engaged state by locking the cargo net to the hook member.
