Elastic Tab Guide Geometry for Stable Battery Lead Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tab guides have a limited spread angle, leading to issues with inserting battery cell leads, causing damage and failure in electrical characteristic inspections, and existing widening solutions result in guide member collisions and damage during large-scale inspections.
Innovation Solution
A tab guide with inclined inner side surfaces and extending guide members made of elastic material, allowing for increased insertion width and preventing damage by absorbing external impacts, while maintaining stability during multiple battery cell inspections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional magazine is used without a tab guide, then the magazine structure is simple, but the cartridges become disorganized and misaligned during feeding
Solution Approach 1:
A tab guide member is introduced as an intermediary component between the cartridges and the magazine body. This tab guide provides a dedicated guiding surface that directs and aligns cartridges as they are fed into the magazine, ensuring proper orientation and alignment without requiring complex internal magazine structures.
Solution Approach 2:
The alignment function is segmented from the main magazine body and assigned to a separate tab guide member. This allows the tab guide to be optimized specifically for alignment purposes while keeping the magazine structure relatively simple. The tab guide can be easily attached or removed as needed.
2Reliability
If cartridges are loosely stored in the magazine, then insertion is easy, but the cartridges become disorganized and fail to feed properly
Solution Approach 1:
The tab guide acts as a mediator that receives cartridges during insertion and automatically guides them into the correct position. This maintains ease of insertion while ensuring reliable alignment and organization of cartridges in the magazine.
Solution Approach 2:
The tab guide pre-aligns cartridges during the insertion process itself, performing the alignment action before the cartridges are fully seated in the magazine. This preliminary alignment ensures that subsequent feeding operations are reliable without requiring additional adjustment steps.
3Productivity
If the magazine is filled quickly without guidance, then loading speed is high, but cartridges are not properly aligned
Solution Approach 1:
The tab guide provides continuous guidance during the rapid loading process, allowing cartridges to be inserted quickly while maintaining proper alignment. The guiding surface actively directs each cartridge as it enters the magazine, ensuring alignment is achieved regardless of loading speed.
