Battery Pack Housing Guide Ribs for Assembly Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery packs face assembly defects and structural instability issues, particularly at corner portions, due to improper formation of reinforcing ribs, leading to increased production costs and reduced assembly efficiency.
Innovation Solution
The battery pack design incorporates a coupling structure with guide ribs and projections on the upper and lower cases, allowing for improved alignment and support of reinforcing ribs, enhancing assembly precision and structural stability by using inclined surfaces and tapered shapes to facilitate easier insertion and secure fastening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If reinforcing ribs are formed in the battery pack housing, then structural stability is improved, but assembly precision deteriorates due to misalignment and assembly defects
Solution Approach 1:
Guide ribs are formed in advance on the housing to preliminarily position and align the reinforcing ribs before final assembly. This preliminary action ensures that the reinforcing ribs are correctly positioned, preventing misalignment and assembly defects while maintaining structural stability.
Solution Approach 2:
Guide ribs act as an intermediary element between the housing and the reinforcing ribs. The guide ribs facilitate the correct positioning and alignment of the reinforcing ribs during assembly, thereby improving assembly precision without compromising the structural stability provided by the reinforcing ribs.
2Manufacturing precision
If complex coupling structures with multiple ribs and projections are used, then assembly precision is improved, but device complexity increases
Solution Approach 1:
The coupling structure merges multiple functions into a single integrated design. The guide ribs and reinforcing ribs are combined in such a way that they work together as a unified system, reducing the need for separate alignment mechanisms and simplifying the overall structure while maintaining high assembly precision.
Solution Approach 2:
The guide ribs serve multiple functions: they guide the positioning of reinforcing ribs, provide structural support, and ensure proper alignment during assembly. This multi-functionality reduces the need for additional components, thereby simplifying the device complexity while improving assembly precision.
3Manufacturing precision
If proper alignment and support structures are added to improve assembly precision, then assembly workability is improved, but manufacturing complexity increases
Solution Approach 1:
The guide ribs are formed during the housing manufacturing process itself, rather than being added as separate components. This preliminary action integrates the alignment function into the base manufacturing step, improving assembly workability without significantly increasing manufacturing complexity.
Solution Approach 2:
The guide ribs are designed to automatically guide and align the reinforcing ribs during assembly without requiring additional tools or complex manufacturing processes. The structure serves itself by providing built-in alignment features that simplify both manufacturing and assembly operations.

AI summary
A battery pack has a first housing including a first fastening portion and a first rib, and a second housing including a second fastening portion fastened to the first fastening portion and a second rib. The first rib is near the first fastening portion, and the second rib is between the first housing and the first rib.
