Energy Storage Harness Plate Locking Structure Against Vibration Shift
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In energy storage apparatuses where a plate-shaped member is arranged above an energy storage device, the position of the plate-shaped member can be displaced due to warping or external vibrations, leading to detachment from other members.
Innovation Solution
The energy storage apparatus includes an energy storage device, a plate-shaped first member arranged above the device, and a second member below the first member. The first member has a convex part projecting towards the second member, which includes a concave part or through hole for insertion, and a second convex part surrounding the periphery of the first convex part to secure it.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a plate-shaped first member is arranged above the energy storage device to save space, then the space utilization is improved, but the position stability of the first member deteriorates due to warping or external vibrations
Solution Approach 1:
The connection structure is segmented into multiple independent elements: a first convex part for insertion, a first concave part or through hole to receive it, and a second convex part surrounding the periphery. This segmentation allows each element to perform its specific function in preventing displacement while maintaining overall compactness.
Solution Approach 2:
The first convex part is inserted into the first concave part or through hole, and the second convex part is arranged to surround the periphery of the first convex part. This nested configuration allows multiple positioning features to be integrated within a compact structure, achieving stable connection without increasing overall volume.
2Volume of moving object
If the first member is made thin and plate-shaped to reduce volume, then the volume is reduced, but the first member becomes prone to detachment under vibration or impact
Solution Approach 1:
The first member is designed with localized convex parts at specific positions rather than making the entire member thick or rigid. The first convex part provides insertion engagement, while the second convex part provides peripheral surrounding engagement. This local quality approach maintains the thin plate shape for volume reduction while ensuring attachment reliability through strategically placed structural features.
Solution Approach 2:
The connection mechanism transitions from a single-plane connection to a multi-dimensional engagement system. The first convex part extends in one direction for insertion, while the second convex part extends in another direction to surround the periphery. This dimensional approach allows a thin plate member to achieve reliable attachment without increasing its volume.
3Device complexity
If a simple plate structure is used for the first member, then the device complexity is reduced, but the positioning precision and stability deteriorate
Solution Approach 1:
The connection structure employs asymmetric features: the first convex part has a specific shape for insertion into the first concave part or through hole, while the second convex part is designed to surround the periphery of the first convex part. This asymmetric design provides precise positioning and prevents displacement in multiple directions, achieving high positioning precision without requiring complex overall structure.
