Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cable type secondary batteries face issues with electrode spacing and increased outer diameter due to the integration of signal cables, making them difficult to produce in mass quantities and prone to damage upon bending.
Innovation Solution
A novel cable type secondary battery design featuring a cable-type core portion with a helically wound positive and negative electrode wire structure, each with a porous coating layer, and optionally including a signal cable within the core, which prevents electrode spacing and maintains flexibility, while a protective coating and electromagnetic field interruption layer enhance durability and signal integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a signal cable is disposed outside the cable type secondary battery with a predetermined interval, then signal transmission function is achieved, but the overall outer diameter of the cable increases
Solution Approach 1:
The patent combines the power supply function (cable-type secondary battery) and signal transmission function (signal cable) into a single integrated structure. The signal cable is disposed inside the cable-type core portion, merging two separate functions into one composite cable that reduces overall diameter while maintaining both functionalities.
Solution Approach 2:
The signal cable is nested within the cable-type core portion, which itself is surrounded by the electrode assembly. This nested arrangement allows the signal cable to occupy the internal space of the battery structure, eliminating the need for external disposal and reducing the overall outer diameter.
2Adaptability or versatility
If the cable type secondary battery is made flexible and deformable, then adaptability to various applications is improved, but electrode spacing occurs leading to structural instability
Solution Approach 1:
The patent employs a dynamic structure where the electrode assembly and cable-type core portion can deform together as a unified unit. The integrated design ensures that when the cable bends or deforms, the electrodes maintain their relative positions and spacing, preventing structural instability while preserving flexibility.
Solution Approach 2:
By merging the signal cable and battery electrodes into a single integrated assembly, the structure ensures that deformation is distributed uniformly across all components. This prevents relative movement between electrodes that would cause spacing issues, while maintaining the overall flexibility of the cable.
3Adaptability or versatility
If a conventional integrated structure with battery body and signal cable in a casing is used, then both power supply and signal transmission are achieved, but the assemblage process becomes complicated and mass production becomes difficult
Solution Approach 1:
The patent segments the integrated cable structure into distinct functional portions: the cable-type core portion containing the signal cable, and the electrode assembly with positive and negative electrodes. This segmentation allows each component to be manufactured separately and then assembled in a straightforward manner, reducing overall assembly complexity while maintaining integration.
Solution Approach 2:
The cable-type core portion serves multiple functions: it provides structural support, contains the signal cable for communication, and acts as a separator between electrodes. This multi-functionality reduces the number of separate components needed, simplifying both manufacturing and assembly processes.
