Adjustable Battery Box Spacers for Secure Multi-Size Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery boxes struggle to accommodate batteries of varying sizes due to fixed dimensions, leading to instability and potential shifting during transport, especially when protecting against rain and water exposure.
Innovation Solution
The battery box design incorporates angled guideways and spacers with sliding dovetail joints and a flexible, bow-tie-shaped cross-section, allowing for adjustable positioning to securely fit batteries of different sizes by narrowing the gap between spacers as they are moved downward, ensuring a stable and watertight enclosure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed dimensions are used for the battery box, then manufacturing is simple and cost-effective, but the battery box cannot accommodate batteries of varying sizes, leading to instability and shifting during transport
Solution Approach 1:
The battery box employs movable spacers that can slide along guideways, transforming the static structure into a dynamic one. The spacers are positioned by holes that align with corresponding holes in the guideways, allowing the gap between spacers to be adjusted to match different battery dimensions while maintaining stability during transport
2Reliability
If fixed spacers are used to secure the battery, then the structure is simple, but the battery cannot be securely held when dimensions vary, causing potential shifting
Solution Approach 1:
The spacers are designed to be movable rather than fixed, allowing them to be repositioned along the guideways to accommodate different battery sizes. The alignment holes provide a simple mechanism for adjusting the spacer positions while ensuring reliable securing of the battery during transport
3Adaptability or versatility
If the gap between spacers is fixed, then manufacturing is easier, but batteries of different sizes cannot be accommodated securely
Solution Approach 1:
The gap between spacers is made adjustable through the movable spacer design. Each spacer can be independently positioned along its guideway by aligning holes, allowing the gap to be precisely controlled for different battery dimensions without requiring complex manufacturing processes
Solution Approach 2:
The battery box is segmented into modular components including the box body, guideways, and spacers. This segmentation allows independent adjustment of spacer positions to achieve the correct gap dimension for different battery sizes while maintaining manufacturing simplicity

AI summary
A battery box has front and rear walls and first and second sidewalls defining an interior of the battery box. A first guideway is provided on a surface of the first sidewall that faces the interior. A second guideway is provided on a surface of the second sidewall that faces the interior. The first and second guideways extend in the height direction. A first spacer is configured to move in the height direction along the first guideway, and a second spacer is configured to move in the height direction along the second guideway. The first and second guideways and/or the first and second spacers have an angled surface so that as the first and second spacers are moved downwardly in the height direction along the respective first and second guideways, a gap defined in the length direction between the first and second spacers is narrowed.
