Onboard EV Charging Cable Housing for Compact Connector Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recharging units for electric vehicles are complex, costly, and lack adaptability to different connector types, making them difficult to integrate into limited onboard vehicle spaces effectively and intuitively.
Innovation Solution
A modular recharging unit with a hollow supporting and containment body housing a charging cable and electrical connector, featuring a manual opening, a coiled cable design, and a receiving seat for the connector, along with drainage openings and lighting, to facilitate intuitive and effective recharging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rechargeable battery is integrated into the motor vehicle body, then the vehicle can be recharged at charging stations, but the vehicle body becomes top-heavy and unstable
Solution Approach 1:
The battery system is divided into two separate components: a rechargeable battery unit that can be detached and a permanent battery housing integrated into the vehicle body. This segmentation allows the rechargeable component to be removed after charging, preventing permanent weight addition to the vehicle body and maintaining stability while still enabling recharge capability.
2Adaptability or versatility
If a rechargeable battery is integrated into the motor vehicle body, then the vehicle can be recharged at charging stations, but the cost of the vehicle increases
Solution Approach 1:
By separating the rechargeable battery from the vehicle body integration, the system allows users to purchase only the battery unit separately rather than paying for a fully integrated hybrid system. This reduces the base vehicle manufacturing cost while still providing recharge capability through the optional battery attachment.
Solution Approach 2:
The rechargeable battery unit functions as a temporary, replaceable component that can be charged externally and then removed. This approach is more cost-effective than integrating permanent charging infrastructure into the vehicle body, as the battery unit can be independently manufactured and replaced without modifying the vehicle structure.
3Adaptability or versatility
If the battery housing is made large to accommodate the rechargeable battery, then the battery can be recharged, but the vehicle body requires extensive modification
Solution Approach 1:
The battery system is divided into a removable battery unit and a simple housing structure. The housing requires minimal modification to the vehicle body, while the battery unit itself contains all necessary components for charging. This segmentation minimizes vehicle body modification while enabling recharge capability.
Solution Approach 2:
The rechargeable battery is extracted as a separate, self-contained unit that can be attached to or removed from the vehicle body. This extraction eliminates the need for extensive vehicle body modifications, as the battery housing can be independently configured and attached using minimal structural changes to the vehicle.
