Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery technologies face challenges in improving energy density while ensuring safety, particularly due to poor connection reliability between connection members and battery cell groups, which can lead to safety risks during vibration.
Innovation Solution
The proposed solution involves a battery design where a connection member is fixed to a fixed base on a separation beam, constraining its movement and enhancing connection reliability between the connection member and the battery cell groups, thereby improving safety and energy density.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the connection member is not fixed to a fixed base, then the structure is simpler and easier to manufacture, but the connection reliability deteriorates due to movement during vibration
Solution Approach 1:
The fixed base acts as an intermediary component between the connection member and the battery cell groups. It provides a stable mounting platform that constrains the connection member's movement, thereby improving connection reliability without requiring direct complex fixation between the connection member and battery components.
Solution Approach 2:
The battery assembly is segmented into distinct functional components: the connection member for electrical connection, the fixed base for positioning and constraint, and the battery cell groups. This segmentation allows each component to be optimized independently while improving overall connection reliability through the dedicated fixed base structure.
2Reliability
If the connection member is constrained by the fixed base, then the connection reliability improves, but the device complexity increases due to additional components
Solution Approach 1:
The fixed base integrates multiple functions into a single component: it serves as the mounting structure for the connection member, the positioning element that constrains movement, and the structural support for the battery assembly. This merging reduces the total number of components while maintaining improved connection reliability.
3Ease of operation
If the connection member is allowed to move freely, then the ease of assembly improves, but the safety deteriorates due to joint damage risk during vibration
Solution Approach 1:
The fixed base is pre-configured with installation grooves and positioning features that guide the connection member into the correct position during assembly. This preliminary structuring ensures proper alignment and constraint before the battery is subjected to vibration, preventing joint damage while maintaining assembly ease.
4Object-affected harmful factors
If the fixed base is added to constrain the connection member, then the safety improves by reducing joint damage risk, but the manufacturing complexity increases
Solution Approach 1:
The fixed base is designed with specific geometric parameters including installation groove dimensions, positioning feature sizes, and material properties that are optimized for both manufacturing ease and protective function. By carefully selecting these parameters, the design achieves joint damage prevention while maintaining manufacturability.
