Solution Overview

Problem

Existing battery testing devices, either crimp-type or clamp-type, have limited testing ranges and incur inconvenience due to the need for direct contact with electrode terminals, restricting their applicability to batteries with specific terminal configurations.

Innovation Solution

A test clip comprising a clip body and a base detachably connected to a crimp probe head, allowing conversion between crimp-type and clamp-type testing environments, with features like snap-fit connections and axial limits to enhance stability and ease of use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a testing device is designed as a fixed crimp-type or clamp-type structure, then it can be applied to corresponding specific testing scenarios, but it limits the testing ranges and reduces adaptability to different battery terminal configurations

Engineering Contradiction:
Improvetesting rangeVSAvoiddevice structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The testing device is divided into separate modular components: a base with inserting portion, a clip body with clamping portions, and a probe. These modules can be assembled and disassembled to adapt to different testing scenarios, transforming a fixed structure into a configurable system that maintains simplicity while expanding versatility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The device incorporates movable and adjustable elements, including the detachable base-clip connection and the positionable probe within the clamping portions. This dynamic configuration allows the testing device to adapt between crimp-type and clamp-type testing modes, expanding its application range without requiring multiple fixed devices.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If a crimp probe head is directly connected to a clip body for testing, then electrical connection is achieved, but direct contact with electrode terminals is required which reduces convenience and increases risk of contact issues

Engineering Contradiction:
Improvetesting convenienceVSAvoidcontact stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The base with inserting portion acts as an intermediary component between the probe and the battery terminal. It provides a stable connection interface that mediates the electrical connection, reducing the need for direct contact between the clip body and electrode terminals, thereby improving both convenience and contact reliability.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of manufacture

If a detachable connection mechanism is implemented between the base and crimp probe head, then versatility and ease of assembly are improved, but connection stability may be reduced

Engineering Contradiction:
Improveassembly easeVSAvoidconnection stability
Core Design Contradiction:
Ease of manufactureVSStability of the object's composition

Solution Approach 1:

The inserting portion of the base is designed to fit within or alongside the crimp probe head in a nested configuration. This nesting arrangement provides a compact, stable connection that is easy to assemble while maintaining structural integrity during use, balancing detachability with connection stability.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

This application provides a test clip and a testing assembly and relates to the technical field of voltage testing. The test clip includes a clip body and a base. The clip body is configured to clamp a piece under test. The base is connected to the clip body, and the base is configured to be detachably connected to a crimp probe head to achieve an electrical connection between the crimp probe head and the clip body. The test clip is divided into the clip body and the base connected to each other. The clip body is configured to clamp the piece under test, and the base is configured to be detachably connected to the crimp probe head to achieve the electrical connection between the crimp probe head and the clip body, so that the piece under test can be clamped by the clip body for testing. This transforms a crimp-type testing device into a clamp-type testing device which can be used in a testing environment that requires clamping, thereby improving the convenience in testing.
