Battery Support Structure With Segmented Locking Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery support structures fail to stably hold batteries when inertial forces cause upward movement, leading to potential release due to upward forces applied to fastening rods.
Innovation Solution
A battery support structure with a pedestal section, a locking protruding part, and a locking part that includes an inserting part and a second locking hole formed at a predetermined distance from the first locking hole, which distributes load and prevents breakage by guiding the inserting part into the second locking hole, maintaining locking and stabilizing the battery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single locking hole is used in the locking protruding part, then the structure is simple, but the locking part may break completely under inertial forces
Solution Approach 1:
The locking protruding part is segmented into multiple locking holes (first locking hole and second locking hole) positioned at different locations. This segmentation allows the structure to distribute mechanical loads across multiple points, preventing complete failure when one locking hole experiences excessive stress from inertial forces during battery displacement.
Solution Approach 2:
The second locking hole is positioned in advance at a location that can arrest crack propagation. When cracks develop from the first locking hole under load, the second locking hole serves as a pre-positioned stop point that cushions against complete structural failure, allowing the locking part to maintain functionality even after partial damage.
2Reliability
If the locking part is designed to resist upward forces, then battery stability improves, but the locking protruding part may break due to concentrated load
Solution Approach 1:
The locking protruding part is divided into multiple locking holes that distribute the upward inertial forces across separate locations. This segmentation prevents concentrated loading at a single point, reducing the risk of breakage while maintaining the overall strength and stability of the battery holding structure.
Solution Approach 2:
Different regions of the locking protruding part have different functional qualities: the first locking hole provides primary locking engagement, while the second locking hole provides backup support and crack arrest. This local differentiation of function allows the structure to resist upward forces effectively while preventing catastrophic failure through strategic placement of reinforcement features.

AI summary
A battery support structure includes a pedestal section configured to come in contact with a first surface of a battery in order to support the battery, a locking protruding part formed at the pedestal section, and a locking part that includes an inserting part arranged to be inserted in a first locking hole and that is configured to come in contact with at least a portion of a third surface of the battery facing the opposite side of the first surface, wherein the battery is supported in a state in which the inserting part is inserted in the first locking hole, and a second locking hole is formed in the locking protruding part at a position deviated a predetermined distance from the first locking hole toward a side closer to the third surface of the supported battery.
