Conductive Module Holding Mechanism Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional conductive modules for vehicle battery packs face challenges in the engagement workability of their holding mechanisms due to the flexible hinge body, which can displace the pivot axis, making it difficult to consistently insert the claw portion into the inserted portion during the closing operation.
Innovation Solution
The conductive module incorporates a holding mechanism with a first engagement holder and a second engagement holder, featuring a first introduction portion that guides the second engagement holder to ensure the claw portion is inserted correctly, even when the pivot axis is displaced, using a sliding contact surface and an inclined surface to maintain contact and guide the second engagement holder to the first introduction portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible hinge body is used to connect the housing body and lid body, then the hinge body can accommodate pivot axis displacement between housing body side and lid body side, but the pivoting locus of the lid body changes each time the pivoting motion is performed, making it difficult to consistently insert the claw portion into the inserted portion
Solution Approach 1:
The patent introduces a guide portion as an intermediary element between the claw portion and the inserted portion. This guide portion actively guides the claw portion along its movement path, ensuring consistent alignment with the inserted portion despite pivot axis displacement caused by the flexible hinge body. The guide portion mediates the interaction between the movable lid body and the housing body, transforming the problematic pivot displacement into a manageable guiding motion.
Solution Approach 2:
The guide portion is pre-configured in a fixed position on the housing body to establish a predetermined guiding path. This preliminary arrangement ensures that before the claw portion attempts to engage with the inserted portion, it is already directed along the correct trajectory. The guide portion performs the preliminary action of aligning the components, eliminating the need for precise manual positioning during operation.
2Adaptability or versatility
If the pivot axis position changes due to hinge body flexibility, then the hinge body can function with displacement, but the pivoting locus of the claw portion with respect to the introduction portion changes, requiring conscious awareness of positional relationship for successful engagement
Solution Approach 1:
The guide portion serves as a mediator that simplifies the engagement process by providing a fixed reference path. Instead of requiring the operator to consciously manage the changing positional relationship between the claw portion and inserted portion, the guide portion automatically compensates for pivot axis displacement. This intermediary element transforms a complex operational task into a simple insertion motion.
Solution Approach 2:
The guide portion enables the holding mechanism to be self-aligning. As the lid body pivots with the flexible hinge body, the guide portion automatically directs the claw portion along the correct path to engage with the inserted portion. The system performs its own alignment function without requiring external intervention or operator awareness of the dynamic positional changes.
