Guide Rod Secures Back-to-Back Energy Storage Cells
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current energy storage devices with double-layer capacitors are costly due to the need for expensive brackets or housings and lack a defined position for the storage cells, leading to high fabrication costs.
Innovation Solution
The design of energy storage devices with back-to-back storage cells featuring a continuous opening between the plus and minus poles, secured by a guide rod, which allows for a mechanically reliable and cost-effective series circuit, along with a diagnostic circuit and electrical connections that are shielded and easily accessible, ensuring reliable contact and positioning even under vibration and shock.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If storage cells are welded together or retained within brackets or housings, then mechanical stability and positioning are ensured, but fabrication costs increase significantly
Solution Approach 1:
The patent introduces a guide rod as an intermediary component that passes through continuous openings in the storage cells. This guide rod serves as a simple mechanical mediator that aligns and secures the storage cells in a series configuration without requiring complex welding operations or expensive brackets, thereby reducing fabrication costs while maintaining mechanical stability
Solution Approach 2:
The patent divides the securing function into individual segments - each storage cell has its own continuous opening through which the guide rod passes. This segmentation allows each cell to be independently positioned and secured along the guide rod, simplifying the overall assembly process and reducing the need for complex integrated mounting structures
2Manufacturing precision
If storage cells are secured with brackets or housings, then defined positioning is achieved, but device complexity and cost increase
Solution Approach 1:
The guide rod acts as a simple linear intermediary that provides a defined position for each storage cell along its length. This straightforward mechanical guide eliminates the need for complex positioning mechanisms, brackets, or housings, achieving precise positioning with minimal structural complexity
Solution Approach 2:
The patent extracts the essential positioning function from complex bracket or housing structures and implements it through a simple guide rod passing through continuous openings. This extraction removes unnecessary structural complexity while retaining the core function of defined positioning

AI summary
An energy storage device is provided including multiple back-to-back-disposed storage cells, from the first end of which the plus pole is made to emerge and from the other end of which the minus pole is made to emerge, thereby creating a series circuit of the storage cells. In order to reduce fabrication costs, it is proposed that each of the storage cells have a continuous opening between the plus pole and the minus pole, through which opening a guide rod extends that secures the back-to-back-disposed storage cells in this position.
