Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for stacking conductive monocells in the production of electrical energy storage devices face challenges in achieving precise and rapid stacking, leading to operational issues and reduced productivity due to the need for slowing down the monocell release or risking misalignment, which impacts the quality and efficiency of the production process.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If forced release or on-the-fly stacking is used, then stacking speed is improved, but alignment precision deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-positioning multiple monocells on the transfer conveyor in a queue formation before the stacking operation begins. This allows the stacking mechanism to simply transfer pre-aligned monocells vertically to the stack, eliminating the need for real-time alignment during stacking and thereby maintaining both high speed and high precision.
2Manufacturing precision
If monocell release speed is slowed down, then alignment precision is improved, but overall productivity deteriorates
Solution Approach 1:
The patent implements continuity of useful action by maintaining constant high-speed transfer of monocells from the production line to the stacking position. The pre-positioning queue ensures that the stacking operation can proceed continuously without interruptions or speed reductions, thereby maintaining both high productivity and high precision throughout the process.
3Device complexity
If traditional stacking methods are used, then equipment complexity is reduced, but operational time increases
Solution Approach 1:
The patent applies segmentation by dividing the stacking operation into distinct functional stages: the transfer conveyor handles horizontal transport and pre-positioning of monocells, while the stacking mechanism handles vertical stacking. This functional segmentation allows each component to be optimized for its specific task, reducing overall operational time while maintaining manageable equipment complexity.

AI summary
An apparatus for stacking monocells for producing electrical energy storage devices, each consisting of electrode films, and at least one separator interposed between them. The apparatus includes a transport member which receives a stack of monocells and a collection device provided with a support member movable along a functional axis between a collection position, in which it is within the overall dimensions of one of the monocells, and a rest position, in which it is outside the overall dimensions of that monocell, and a movement member selectively movable, independently of the support member, along a stacking axis between a support position, in which it cooperates with the support member, and at least one release position, in which it positions the monocells, in cooperation with the transport member.
