Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery designs have low space utilization, which hinders the improvement of energy density due to the need for reserved space for electrical energy lead-out members and sampling units, leading to instability and safety risks from disconnection and potential fires.
Innovation Solution
The battery integrates the electrical energy lead-out member and sampling unit into the end plate, eliminating the need for reserved space and enhancing connection stability by embedding the lead-out member and penetrating the sampling unit through the plate, thereby improving space utilization and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wire passing space is reserved between the end plate and box body wall for the electrical energy lead-out member, then the lead-out member can be properly positioned, but space utilization of the battery is reduced
Solution Approach 1:
The patent merges the electrical energy lead-out member with the end plate by embedding the lead-out member directly into the end plate structure. This integration eliminates the need for separate wire passing spaces between the end plate and box body wall, thereby improving space utilization while maintaining connection stability through the integrated design.
2Reliability
If wire passing space is reserved between the end plate and box body wall for the sampling unit, then the sampling unit can be properly positioned, but space utilization of the battery is reduced
Solution Approach 1:
The patent merges the sampling unit with the end plate by having the sampling unit penetrate through the end plate. This integration eliminates the need for separate wire passing spaces between the end plate and box body wall, thereby improving space utilization while maintaining connection stability through the integrated design.
3Volume of moving object
If the electrical energy lead-out member and sampling unit are integrated to the end plate, then space utilization is improved, but the connection stability may be compromised
Solution Approach 1:
The electrical energy lead-out member is embedded into the end plate, creating an integrated structure where the lead-out member becomes part of the end plate itself. This merging ensures stable connection while improving space utilization.
Solution Approach 2:
The sampling unit penetrates through the end plate, with its wiring nested within the end plate structure. This nesting approach allows the sampling unit to be integrated into the end plate while maintaining stable electrical connections and improving overall space utilization.
