Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in battery modules is optimizing the arrangement of electrode connectors to achieve effective electrical connections between batteries while ensuring structural integrity and safety, particularly in preventing foreign matter ingress and managing gas and liquid release during potential explosions.
Innovation Solution
The solution involves a jumper electrode connector with a through hole and an explosion-proof valve, where the orthographic projection of the through hole overlaps with the explosion-proof valve and an insulating structure, allowing gas and liquid to be released safely through the through hole, and providing insulation to prevent foreign matter entry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrode connectors are arranged to achieve series or parallel connection between batteries, then electrical connection effectiveness is improved, but structural complexity and safety risks increase
Solution Approach 1:
The patent combines multiple functions into a single integrated electrode connector structure. The connector simultaneously provides electrical connection between batteries, structural support, and safety functions through integrated design elements including connection holes, reinforcement ribs, and sealing structures. This merging approach reduces the number of separate components while maintaining comprehensive functionality.
Solution Approach 2:
The electrode connector is designed as a multi-functional component that performs various roles: electrical conduction through contact terminals, mechanical support through reinforcement ribs, sealing through integrated seals, and structural alignment through positioning holes. This universal design allows a single component to fulfill multiple requirements that would traditionally need separate parts.
2Area of stationary object
If electrode connectors are positioned close to batteries for compact arrangement, then space utilization is improved, but risk of foreign matter ingress and short circuit increases
Solution Approach 1:
The patent employs sealing structures including sealing rings or sealing films that create protective barriers between the electrode connector and the external environment. These flexible sealing elements prevent foreign matter such as dust, moisture, or other contaminants from entering the connection interface, thereby maintaining electrical safety while allowing compact positioning.
Solution Approach 2:
The sealing structures act as intermediary elements between the electrode connector and the surrounding environment. This intermediary layer isolates the critical electrical connection area from harmful external factors while maintaining the compact spatial arrangement, effectively mediating between the need for proximity and the need for protection.
3Reliability
If through holes are provided in electrode connectors for gas and liquid release, then safety during explosion is improved, but risk of foreign matter entry increases
Solution Approach 1:
The patent implements different quality characteristics in different regions of the electrode connector. The areas around through holes are equipped with enhanced sealing structures, reinforcement ribs, or protective coatings specifically localized to those regions. This local quality enhancement provides targeted protection against foreign matter entry at the vulnerable through hole locations while maintaining the overall safety function.
Solution Approach 2:
The sealing structures and protective features around through holes are pre-configured in advance to prevent foreign matter entry before it can occur. This preliminary protective action ensures that even when gas or liquid needs to escape through the through holes during an explosion event, foreign matter cannot exploit these openings to enter the battery system.
4Object-affected harmful factors
If insulating structures are added between jumper electrode connector and battery, then prevention of foreign matter ingress is improved, but device complexity increases
Solution Approach 1:
The insulating structures are merged with the electrode connector body or the battery housing in an integrated design. Rather than being separate added components, the insulating features are incorporated into the existing structural elements, such as insulating ribs formed as part of the connector mold or insulating layers integrated into the housing design, thereby providing protection without significantly increasing overall complexity.
