Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery technologies face challenges in ensuring stable connections and rigidity, leading to high failure probabilities due to uneven adhesive thickness and lack of effective displacement restrictions, particularly when battery cells are not flat on both ends, compromising safety and resilience.
Innovation Solution
A battery design incorporating a connecting member with perpendicular first and second connecting plates that enhance connection stability and rigidity by increasing contact areas between battery cells and the carrying assembly, using cambered surfaces and grooves for improved adhesion, and integrating water cooling channels for thermal management.

Engineering Contradiction Analysis
1Reliability
If traditional adhesive bonding methods are used to connect battery cells to the carrying assembly, then the manufacturing process is simple, but the adhesive thickness is uneven and connection stability is poor
Solution Approach 1:
The patent replaces the adhesive bonding system with a mechanical connection system. The connecting member includes a first connecting plate that contacts the battery cell and a second connecting plate that contacts the carrying assembly, forming a mechanical bridge that eliminates the need for adhesive bonding. This substitution resolves the issue of uneven adhesive thickness by using rigid mechanical components with precise geometric interfaces instead of viscous adhesives whose thickness cannot be uniformly controlled.
Solution Approach 2:
The connecting member serves as an intermediary component between the battery cell and the carrying assembly. Rather than directly bonding the battery cell to the carrying assembly (which causes adhesive thickness issues), the patent introduces the connecting member as a mediator with standardized interfaces. The first connecting plate interfaces with the battery cell while the second connecting plate interfaces with the carrying assembly, distributing the connection function and enabling stable mechanical coupling without adhesive thickness problems.
2Reliability
If battery cells are arranged without rigid constraints, then the device complexity is low, but the rigidity of battery grouping is insufficient and failure probability increases
Solution Approach 1:
The patent segments the connection function into distinct components: the first connecting plate segment that interfaces with the battery cell, the second connecting plate segment that interfaces with the carrying assembly, and the connecting portion that joins them. This segmentation allows each component to be optimized for its specific function while collectively providing rigid constraints. The segmented structure enables precise positioning and stable connection without requiring an overly complex overall battery grouping structure.
Solution Approach 2:
The connecting member extends in multiple spatial dimensions to provide comprehensive constraints. The first connecting plate extends in a first direction to contact the battery cell, while the second connecting plate extends in a second direction perpendicular to the first to contact the carrying assembly. This multi-dimensional arrangement creates rigid constraints in multiple directions simultaneously, preventing displacement and enhancing stability without adding excessive structural complexity.
