Clamp Probe Bending Portions for Compact Battery Testing

Solution Overview

Problem

Existing clamp-type probe devices for testing electrical components, such as pouch-type batteries, face challenges in efficiently and reliably clamping test objects without causing damage or stress, while maintaining a compact design and high testing efficiency.

Innovation Solution

A clamp-type probe device comprising a first and second pressed member with clamping portions and a probe head, where the probe head's contacting members have bending portions that engage with assembly holes, allowing for a clamping mechanism that is lightweight, compact, and capable of conducting charge/discharge tests without additional fastening mechanisms, utilizing pneumatic drive units to move the pressed members and maintain alignment through guiding grooves.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If additional fastening mechanisms are used to secure the probe head, then the reliability of the probe device is improved, but the device complexity and size increase

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The contacting members are designed to automatically engage with the assembly holes through their bending portions, eliminating the need for additional fastening mechanisms. The elastic properties of the contacting members enable self-securing through the clamping action itself, achieving reliability without increased complexity

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The bending portions of the contacting members act as intermediaries between the probe head and the assembly holes. These bending portions transmit the clamping force while maintaining electrical contact, serving as a mediating element that secures the probe without requiring separate fastening components

Inventive Principle:
Principle #24Intermediary (Mediator)

2Volume of moving object

If the probe device is designed to be compact, then the manufacturing yield is improved, but the clamping force and testing reliability may be compromised

Engineering Contradiction:
Core Design Contradiction:
Volume of moving objectVSReliability

Solution Approach 1:

The probe device is segmented into modular components: multiple contacting members are distributed across the probe head, each independently engaging with assembly holes. This segmentation allows the compact probe head to deliver clamping force through multiple distributed contact points rather than requiring a single large mechanism

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The contacting members utilize flexible bending portions that can deform elastically to engage with the assembly holes. This flexibility allows the compact probe structure to maintain reliable electrical contact while adapting to slight variations in the test object surface, ensuring testing reliability within a compact form factor

Inventive Principle:
Principle #30Flexible shells and thin films

3Measurement precision

If the contacting members are made rigid to maintain stable electrical contact, then the measurement precision is improved, but the stress transmission to test objects increases causing damage

Engineering Contradiction:
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The contacting members transition from a purely rigid state to an elastic state through their bending portions. This parameter change allows them to maintain stable electrical contact through elastic deformation rather than rigid constraint, reducing stress transmission to the test object while preserving measurement precision

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The bending portions of the contacting members provide beforehand cushioning by absorbing clamping forces through elastic deformation. This cushioning effect protects the test object from excessive stress while ensuring stable electrical contact for precise measurements during the testing process

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)
