Detachable Trunk Cable Storage for Easy-Clean EV Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for an easy-to-clean storage device for charging cables of electrically drivable motor vehicles that prevents the cable from soiling other objects in the trunk while allowing for simple storage and retrieval.
Innovation Solution
A detachable receiving unit is integrated into the side wall of a motor vehicle's trunk, which can be moved between closed and open positions. The unit is designed to store the charging cable at a distance from the trunk's side wall, preventing soiling, and can be easily cleaned when detached.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the charging cable is stored directly in the trunk, then storage is simple, but the cable may soil other objects in the trunk
Solution Approach 1:
The storage system is divided into a fixed recess in the side wall and a detachable receiving unit. The receiving unit is separated from the main trunk space, creating a dedicated compartment that isolates the charging cable from other objects. This segmentation allows simple storage while preventing the cable from soiling other items.
Solution Approach 2:
The receiving unit is extracted as a separate detachable component from the fixed trunk structure. By taking out the storage function into a separate unit that can be removed, the system enables easy cleaning of the receiving unit while maintaining simple storage during normal use.
2Reliability
If the receiving unit is integrated permanently into the side wall, then storage is secure, but cleaning becomes difficult
Solution Approach 1:
The storage system is segmented into a fixed recess structure and a detachable receiving unit. The receiving unit can be removed from the recess for cleaning, while the recess remains fixed and secure in the side wall. This segmentation resolves the contradiction between secure storage and easy cleaning.
Solution Approach 2:
The receiving unit transitions from a static integrated structure to a dynamic detachable component. It can be inserted into the recess for secure storage and removed when cleaning is needed. This dynamic capability allows the system to switch between secure storage mode and cleaning mode.
3Object-affected harmful factors
If the receiving unit is moved out of the recess, then the charging cable is protected from soiling the side wall, but the structure becomes more complex
Solution Approach 1:
The system is segmented into a fixed recess and a movable receiving unit. The receiving unit can be positioned in two states: inserted into the recess (protected position) or removed (cleaning position). This simple binary segmentation protects the side wall from soiling while avoiding complex multi-position mechanisms.
Solution Approach 2:
The receiving unit is extracted as a separate removable component that can be completely taken out of the recess. This extraction approach simplifies the protection mechanism - the unit is either in the recess protecting the wall or removed for cleaning, without requiring complex intermediate positions or mechanisms.

AI summary
A storage device (20) is provided for a charging cable that can charge an electrically drivable motor vehicle. The motor vehicle has a trunk (10) with side wall (16). A recess (22) for receiving the charging cable is formed in the side wall (16) and a receiving unit (24) is fastened detachably in the recess (22). The receiving unit (24) can be moved from a closed position, in which the receiving unit (24) is received in the recess (22), to an open position, in which the receiving unit (24) is positioned at least partially out of the recess (22). A receiving opening (26) of the receiving unit (24) is covered by the side wall (16) in the closed position and is accessible for the charging cable in the open position. The separate and detachable receiving unit (24) permits simple storing of a charging cable in an easy-to-clean storage device (20).
