Solution Overview
Problem
Battery testing is an expensive and time-consuming process to determine which materials improve battery design, particularly for lead-acid batteries, requiring the assembly and testing of large numbers of batteries over months.
Innovation Solution
A rapid testing system for lead-acid battery materials using a working electrode with a replaceable cup that holds active material, allowing quick testing of multiple materials and conditions, utilizing a three-electrode system with a conductive rod, insulating body, and removable caps to maintain contact and seal, facilitating faster and more detailed analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional battery testing methods are used to determine which materials improve battery design, then comprehensive testing of multiple factors can be performed, but the process becomes expensive and time-consuming
Solution Approach 1:
The battery system is segmented into modular components (body, caps, rod, cup with active material) that can be independently assembled and tested. This allows individual material components to be tested separately and rapidly combined, enabling comprehensive material evaluation without requiring complete battery assembly for each test variant.
Solution Approach 2:
The testing apparatus uses universal components (standardized body, caps, rod structure) that can accommodate multiple different active materials in the cup. This multi-functional design allows the same apparatus to test various materials systematically, reducing the need for specialized equipment for each material and accelerating the testing process.

This allows individual material components to be tested separately and rapidly combined, enabling comprehensive material evaluation without requiring complete battery assembly for each test variant.
Solution Approach 2:
The cup containing the active material can be easily removed, discarded, and replaced with a new cup containing a different material. This disposable cup approach eliminates the need for complex disassembly and cleaning procedures, reducing labor costs and allowing rapid iteration through multiple material tests with the same apparatus.
3Productivity
If a replaceable cup design is used to hold active material, then quick testing of multiple materials is enabled, but additional components (caps, rod, spring) are required
Solution Approach 1:
The battery system is segmented into modular components (body, caps, rod, cup with active material) that can be independently assembled and tested. This allows individual material components to be tested separately and rapidly combined, enabling comprehensive material evaluation without requiring complete battery assembly for each test variant.
Solution Approach 2:
The cup with active material is nested within the body structure, which itself is contained within the caps. The rod extends through the body and contacts the cup from the interior. This nested arrangement allows compact integration of multiple functional components while maintaining easy access to the replaceable cup, balancing complexity with productivity.

Function Achieved in This Case
Enables faster, more cost-effective, and detailed testing of lead-acid battery materials with reduced resource and time requirements, providing a more accurate understanding of electrochemical performance and enabling larger testing arrays with less expensive equipment.
Implementation Method 1
a spring, wherein the spring exerts a force on a flange of the rod and the first cap to maintain contact between the rod and the cup when the first cap is coupled to the body
Implementation Method 2
the second cap exerting a force on the cup to press the cup against the gasket
Implementation Method 3
The gasket creates a seal between the cup and the body
