Detachable Charging Lid Hinge for Narrow-Space Vehicle Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Charging lids can obstruct charging operations in confined spaces due to insufficient space, hindering vehicle charging.
Innovation Solution
A charging lid structure featuring a lid-side hinge portion with a bearing portion, a body-side hinge portion, a rotary shaft, and a fixing pin that allows the lid to be rotated and removed, minimizing obstruction during charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the charging lid is kept closed to maintain a compact appearance, then the vehicle maintains a streamlined profile, but the lid cannot be removed to allow charging in narrow spaces
Solution Approach 1:
The charging lid structure is divided into separable components: the lid body and the hinge portion. The hinge portion can be detached from the lid, allowing the lid to be completely removed when needed for charging in narrow spaces, while remaining attached during normal operation to maintain a compact appearance.
Solution Approach 2:
The hinge structure transitions from a static permanent connection to a dynamic removable connection. The fixing pin mechanism allows the hinge portion to be easily attached and detached, providing adaptability between different charging scenarios without requiring a permanently complex structure.
2Ease of operation
If the lid is designed to open and close conventionally, then the structure remains simple and cost-effective, but the lid obstructs charging operations in confined spaces
Solution Approach 1:
The charging lid system is segmented into the lid body and a separate hinge portion that can be detached. This allows the lid to be completely removed rather than merely opened, eliminating obstruction during charging in narrow spaces while maintaining a simple conventional lid design when attached.
Solution Approach 2:
The hinge portion is extracted as a separate detachable component from the lid body. This extraction allows the lid to be completely removed from the vehicle when needed for charging in confined spaces, while the simple conventional lid design is preserved when the hinge is attached.
3Adaptability or versatility
If a removable lid design is implemented to enable charging in narrow spaces, then charging accessibility improves, but manufacturing costs and structural complexity increase
Solution Approach 1:
The charging lid is segmented into a lid body and a hinge portion that can be separately manufactured and then assembled. This segmentation enables charging location flexibility while allowing each component to be manufactured using conventional processes, controlling overall manufacturing cost.
Solution Approach 2:
The hinge portion serves multiple functions: it provides the rotational hinge function when attached, and can be easily detached to enable lid removal for narrow space charging. This multi-functionality achieves charging location flexibility without requiring entirely separate systems, helping to control manufacturing costs.

AI summary
The charging lid structure includes a charging lid having a lid-side bearing portion provided on a lid-side hinge portion engaged with the main body side and having a lid-side bearing portion in which a lid-side pin hole is formed on a side surface, a body side hinge portion having a main body-side bearing portion in which a main body-side pin hole communicating with the lid-side pin hole is formed on a side surface, a rotary shaft in which a shaft-side pin hole communicating with the lid-side pin hole is formed in the shaft portion, and the shaft portion is inserted into the lid-side bearing portion and the main body-side bearing portion, and rotatably supports the lid-side hinge portion and the body side hinge portion, and a fixing pin that can be inserted into and removed from the main body-side pin hole, the lid-side pin hole, and the shaft-side pin hole.
