Adjustable Probe Assembly for Multi-Spec Battery Resistance Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery internal resistance detecting devices are limited to detecting the internal resistance of a single battery specification due to fixed probe positions, preventing the detection of batteries with different specifications.
Innovation Solution
The device features adjustable probes that can be positioned to accommodate batteries of varying specifications by allowing the distance between the probes to be adjusted, ensuring stable connection to the positive and negative electrodes, and includes a frame system for precise alignment and detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the probes are fixed at a specific distance, then the connection stability is improved, but the device can only detect batteries of one specification
Solution Approach 1:
The patent applies the dynamics principle by making the probe distance adjustable rather than fixed. The probe assembly can be positioned at different distances to match batteries of various specifications, while maintaining stable connection during measurement. This resolves the contradiction by allowing the system to adapt its configuration dynamically.
Solution Approach 2:
The patent changes the parameter of probe distance from a fixed value to an adjustable variable. By allowing the distance between probes to be modified according to different battery specifications, the device can detect multiple battery types while maintaining reliable contact through proper positioning.
2Adaptability or versatility
If the probes are made adjustable to detect different battery specifications, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The patent segments the probe assembly into adjustable components that can be independently positioned. The probe holder and probe elements are designed as separate, reconfigurable parts that can be adjusted to different distances, simplifying the overall adjustment mechanism while maintaining versatility.
Solution Approach 2:
The patent creates a universal probe assembly that can detect multiple battery specifications through adjustment. The same probe structure serves multiple functions by changing its positioning, eliminating the need for separate probe sets for different battery types and thereby controlling device complexity.

AI summary
The present application relates to a battery internal resistance detecting device and a battery production system. The battery internal resistance detecting device comprises: a first probe used for electrically connecting to a positive electrode of a battery; and a second probe used for electrically connecting to a negative electrode of the battery; wherein a distance between the first probe and the second probe is adjustable. By setting the distance between the first probe and the second probe to be adjustable, the distance between the first probe and the second probe may be adjusted conveniently according to a distance between the positive electrode and the negative electrode of the battery, so that the battery internal resistance detecting device is capable of detecting internal resistances of batteries of different specifications, thereby improving the applicability of the battery internal resistance detecting device.
