Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing weight and size of middle or large-sized battery modules pose a risk of falling during transportation due to the stacking and spacing of battery cells, which existing methods fail to adequately address.
Innovation Solution
A battery module design featuring a battery cell stack with an insulating cover, a holding member, and an adhesive member with an adsorption complementary layer, along with an adhesive tape between cells, to enhance stability and prevent falling during transport, and a method involving an adsorber for secure handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the number of battery cells is increased to meet high power and large capacity requirements, then the power and capacity are improved, but the weight increases and the risk of falling during transportation increases
Solution Approach 1:
The battery module is divided into multiple battery cell stacks, with each stack independently secured by adhesive members. This segmentation allows for better distribution of adhesive forces and reduces the overall risk of falling during transportation.
Solution Approach 2:
Adhesive members are applied to the battery cell stacks before transportation to proactively prevent falling. This preliminary action ensures that the stacks are secured in advance, addressing the transportation risk before it occurs.
2Ease of manufacture
If battery cells are stacked by attaching individual cell tapes, then the battery cell stack can be formed, but stacking steps and battery cell spacing occur that increase the risk of falling during transport
Solution Approach 1:
Multiple battery cells are merged into a unified battery cell stack structure, with adhesive members combining the individual cells into a cohesive unit. This merging eliminates the spacing and stacking steps issues that occur with individual cell tapes.
Solution Approach 2:
Adhesive members serve as an intermediary substance between battery cells, providing a continuous bonding interface that eliminates the gaps and steps created by individual cell tapes while maintaining ease of manufacture.
3Quantity of substance
If the weight of the battery module increases to provide large capacity, then the energy storage capacity is improved, but the stability during transportation deteriorates
Solution Approach 1:
The adhesive members provide a counteracting bonding force that opposes the gravitational effect on the heavy battery module. This anti-weight principle allows the module to maintain stability despite its increased weight and capacity.
Solution Approach 2:
The battery module uses composite construction with adhesive members bonding multiple battery cells into a unified stack. This composite structure distributes the weight and improves stability during transportation while maintaining large capacity.
