Insulation Package Enclose Member for Battery Terminal Sealing
Solution Overview
Problem
Conventional electricity charging/discharging devices with multiple-sided electric conductive terminals face challenges in maintaining a sealed packaging structure due to complex manufacturing processes and quality control issues, leading to deterioration over time.
Innovation Solution
A full-closed type electricity charging/discharging device with an insulation package enclose member, where the electrode plate pair and adjacent electric conductive terminals are sealed with insulation material, allowing for input/output of electric energy through multiple-sided electric conductive terminals, enabling connections in series or parallel configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electric conductive terminals pass through through holes on the housing with additional sealing packaging material, then the device can extend terminals to external for energy input/output, but the sealing structure deteriorates after long-time use due to numerous manufacturing processes and difficult quality control
Solution Approach 1:
The patent merges the sealing function and terminal support function into a single integrated insulation package enclose member. The terminals are sealed at their root portions directly to the electrode plates within the enclosed space, eliminating the need for separate through-hole sealing processes. This integration reduces the number of manufacturing steps and improves sealing reliability while maintaining terminal accessibility for energy input/output.
Solution Approach 2:
The patent implements a nested structure where the electric conductive terminals are contained within the insulation package enclose member, with only the necessary portions exposed for external connection. The sealing packaging material envelops the terminals and electrode plates in a nested configuration, creating a hierarchical enclosure that protects internal components while allowing controlled external access.
2Ease of manufacture
If the housing is welded or adhered with end housing to create a groove structure, then the device can be assembled with multiple components, but the manufacturing process becomes complex and quality control of sealing locations becomes difficult
Solution Approach 1:
The patent combines multiple housing functions into a single insulation package enclose member that serves as both the structural housing and the sealing packaging. This integrated component eliminates the need for separate welding or adhesion processes between housing and end housing, simplifying the manufacturing process while maintaining assembly capability. The single enclose member provides both structural support and sealing functions.
Solution Approach 2:
The insulation package enclose member is designed to perform multiple functions simultaneously: it serves as the housing structure, the sealing packaging, the terminal support, and the insulation barrier. This multi-functional design reduces the total number of components and manufacturing processes required, thereby reducing device complexity while maintaining ease of manufacture through standardized production of a single enclose member type.

AI summary
The present invention provides an electricity charging/discharging device with insulation package enclose member having electrode plate pair with multiple-sided electric conductive terminals, wherein both the electrode plate pair with multiple-sided electric conductive terminals and the section of the electric conductive terminal adjacent to the connected electrode plate extending from at least two sides thereof to the external for inputting/outputting electric energy are sealed covered by a packing material with insulation property to form a full-closed type electricity charging/discharging device with insulation package enclose member such as Lithium-ion Batteries, for instance Lithium Iron Phosphate (LFP) Battery, Lithium Nickel Manganese Cobalt Oxide (NMW) Battery, and Lithium Polymer Battery, or a supercapacity, so the electrode plate pair is able to output or input electric energy to the exterior through an electric conductive interface formed by at least two-sided electric conductive terminal.
