Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery packs have complex assembly processes, high costs, and low space utilization due to multiple structural parts, leading to large product sizes.
Innovation Solution
The energy storage power supply features a housing with an accommodation chamber and positioning grooves for direct cell mounting, reducing assembly steps and parts, and incorporates busbars for parallel/series connections without welding, using fixing collids and reinforcement ribs for structural support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If battery modules are assembled from multiple parts (cell, cell support, busbar, collection plate, screw) and then fixed in housing, then reliable electrical connections and structural support are achieved, but assembly process becomes complex and cost increases
Solution Approach 1:
The patent integrates the cell support, busbar, and collection plate into a single integrated component structure. The support structure includes positioning grooves that directly hold the battery cells, while electrical connection terminals are built into the same structure, eliminating the need for separate busbars and collection plates. This merging of functions reduces the number of parts and simplifies assembly while maintaining reliable electrical connections.
Solution Approach 2:
The support structure serves multiple functions simultaneously: it provides mechanical support for the battery cells, positions them accurately through integrated positioning grooves, and establishes electrical connections through built-in terminals. This multi-functional design replaces multiple specialized components (cell support, busbar, collection plate) with a single universal structure, reducing assembly complexity and part count.
2Strength
If multiple structural parts are used to assemble battery modules and fix them in housing, then structural support and positioning are achieved, but product size increases and space utilization rate decreases
Solution Approach 1:
The support structure is designed as an integrated component that combines mechanical support, positioning, and electrical connection functions. By merging the cell support, positioning mechanisms, and electrical terminals into a single structure, the patent reduces the overall volume required for structural components while maintaining adequate structural support for the battery cells.
Solution Approach 2:
The positioning grooves are directly formed within the support structure itself, creating a nested arrangement where the cell-holding features are integrated into the support body. This nesting eliminates the need for separate positioning components and reduces the overall space required for structural support elements.
3Reliability
If battery module assembly is performed before mounting in housing, then proper cell positioning and electrical connections are established, but assembly time and manufacturing cost increase
Solution Approach 1:
The support structure is pre-formed with integrated positioning grooves and electrical connection terminals during manufacturing. This preliminary preparation of the support structure allows for direct insertion and positioning of battery cells without requiring separate assembly steps for positioning features or electrical connections, thereby improving assembly speed while maintaining positioning accuracy.
Solution Approach 2:
By combining the positioning features and electrical connection terminals into the support structure itself, the patent enables simultaneous achievement of accurate cell positioning and electrical connection during a single mounting operation. This eliminates the need for separate assembly steps that would be required if these functions were provided by separate components.
