Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control cabinets for electrical energy storage devices are complex due to the use of partitions, which occupy space and reduce packing density.
Innovation Solution
A control cabinet or rack design that eliminates the need for partitions by using grooves for energy storage inserts, with each insert having a ground connection and an electrically conductive frame for secure and efficient energy storage, allowing for maximum packing density.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If partitions are used to separate compartments for energy storage devices, then structural stability and organization are improved, but device complexity and space occupation increase
Solution Approach 1:
The control cabinet is segmented into multiple insertion slots formed by grooves on the mounting chassis, allowing individual energy storage devices to be separated and organized without requiring physical partitions between compartments. Each groove defines a specific insertion path and position.
Solution Approach 2:
Instead of using vertical partitions to separate compartments in the horizontal plane, the invention uses grooves to define insertion slots in the vertical dimension, allowing energy storage devices to be arranged one above another without horizontal dividers, thus eliminating the need for partitions.
2Stability of the object's composition
If partitions are used to separate compartments, then organizational structure is improved, but packing density decreases due to space occupied by partitions
Solution Approach 1:
The partition elements are completely removed from the system. Instead of having physical dividers between compartments, the invention uses the grooves on the mounting chassis to define insertion slots, extracting the separation function from physical partitions to the groove structure.
Solution Approach 2:
The mounting chassis combines multiple functions: it provides structural support, defines insertion slots through grooves, and eliminates the need for separate partition components. The grooves serve both as guides and as organizational boundaries without requiring additional space-consuming elements.
3Quantity of substance
If grooves are used instead of partitions, then packing density increases, but electrical contact reliability may worsen
Solution Approach 1:
The ground connection acts as an intermediary element that ensures reliable electrical contact. It includes a contact plate with contact claws that engage with the ground contact of the energy storage device, providing a dedicated electrical connection path independent of the mechanical insertion guidance.
Solution Approach 2:
The electrical connection system is segmented into separate functional elements: the grooves provide mechanical guidance and positioning, while the ground connection with contact claws provides electrical contact. This separation ensures that electrical reliability is not compromised by the space-saving groove design.
