Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the energy-storage device is placed flat during charging and discharging, then the device structure is simple and easy to manufacture, but the electrolyte level decreases causing parts of the electrode assembly to not be immersed, affecting performance and shortening service life
Solution Approach 1:
The patent divides the electrolyte supply system into multiple segments: an electrolyte reservoir, multiple electrolyte supply channels with different orientations, and multiple outlet holes distributed across different surfaces of the electrode assembly. This segmentation allows electrolyte to reach all electrode surfaces through different paths, ensuring complete immersion even when the device is placed flat, while maintaining a simple overall structure that is easy to manufacture.
Solution Approach 2:
The patent introduces multi-dimensional electrolyte supply channels that extend in different spatial directions (horizontal, vertical, inclined) rather than a single vertical channel. By adding dimensional diversity to the electrolyte distribution system, the patent ensures electrolyte can reach electrode surfaces regardless of the device's placement orientation, solving the immersion problem without complicating the basic flat-structure design.
2Productivity
If electrolyte is consumed during charging and discharging, then the charging and discharging processes can proceed, but the electrolyte level lowers causing performance degradation and reduced service life
Solution Approach 1:
The patent pre-configures an electrolyte reservoir that stores additional electrolyte before the device is put into operation. This preliminary action ensures that even as electrolyte is consumed during charging and discharging cycles, the stored electrolyte in the reservoir continues to supply the electrode assembly through the multi-directional channels, preventing the electrolyte level from dropping below the required threshold and thereby extending the device's service life while maintaining continuous operational productivity.
3Device complexity
If a traditional single-channel electrolyte supply system is used, then the device structure is simple, but electrolyte distribution to all electrode surfaces is insufficient when placed flat
Solution Approach 1:
The patent applies local quality by configuring electrolyte supply channels with different orientations (horizontal, vertical, inclined) and distributing outlet holes at specific locations on different surfaces of the electrode assembly. Each local region of the electrode receives electrolyte through optimally oriented channels, ensuring that every local surface area is adequately supplied regardless of the device's placement orientation, thereby achieving reliable comprehensive coverage without excessive overall system complexity.
