Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the electric conductive terminals pass through through holes on the housing with additional sealing packaging material, then the device can achieve electrical connection to the external, but the manufacturing process becomes complex and quality control of the sealing location becomes difficult
Solution Approach 1:
The patent merges the sealing function and electrical connection function into a single integrated structure. The electric conductive terminal itself serves as the sealing element by extending through the housing wall and forming a sealed connection with the housing, eliminating the need for separate sealing packaging material at the through hole location. This integration simplifies the manufacturing process while ensuring reliable sealing.
Solution Approach 2:
The patent extracts the sealing function from the separate sealing packaging material and transfers it to the electric conductive terminal structure. The terminal is designed to form a sealed connection directly with the housing wall, removing the dependency on additional sealing materials and simplifying the overall sealing system.
2Reliability
If the electric conductive terminals pass through through holes on the housing with additional sealing packaging material, then the device can achieve electrical connection to the external, but the sealing structure deteriorates after long-time use
Solution Approach 1:
The patent combines the sealing function and electrical conduction function into a single integrated terminal structure. The electric conductive terminal forms a sealed connection directly with the housing wall, eliminating the interface between separate sealing materials and the through hole that would otherwise deteriorate over time. This unified structure improves long-term durability.
Solution Approach 2:
The electric conductive terminal acts as an intermediary element that simultaneously provides both electrical conduction and sealing functions. Instead of having separate sealing materials that can deteriorate, the terminal itself mediates between the internal battery components and the external environment while maintaining a sealed barrier.
3Productivity
If a housing of groove structure is used with welded or adhered end housing, then the device can be assembled, but numerous manufacturing processes are required
Solution Approach 1:
The patent merges multiple manufacturing operations into fewer integrated steps. The electric conductive terminal is designed to be installed in a way that simultaneously achieves electrical connection, mechanical support, and sealing functions, eliminating the need for separate welding or adhesion processes for end housing assembly.
Solution Approach 2:
The electric conductive terminal serves multiple functions: it provides electrical conduction, mechanical support for the electrode plate, and sealing at the housing penetration point. This multi-functionality reduces the number of separate components and manufacturing processes required, improving overall manufacturing efficiency.

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 (NMC) 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.
