Solution Overview

Problem

Existing charging modules cannot effectively screen batteries that do not meet model requirements, requiring manual removal, which is cumbersome for users.

Innovation Solution

A charging module with a screening assembly and a drive assembly that moves along the width direction of the battery charging case, allowing batteries that meet model requirements to pass through a screening port while those that do not meet the requirements can pass through a small gap due to incomplete obstruction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a screening assembly is added to automatically screen batteries, then the ease of operation is improved, but the device complexity increases

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The screening assembly automatically screens batteries based on model requirements without user intervention. The drive assembly moves the screening assembly to different positions (aligned or offset) and the system self-regulates battery flow through the screening port, eliminating the need for manual battery removal while maintaining operational simplicity.

Inventive Principle:
Principle #25Self-service

2Reliability

If the screening assembly is positioned to align with the battery installation through slot, then batteries meeting model requirements can pass through, but batteries not meeting requirements cannot pass through the small gap

Engineering Contradiction:
Improvescreening accuracyVSAvoidbattery throughput
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The screening assembly is made movable along the width direction of the battery charging case through the drive assembly. It can dynamically switch between two positions: aligned with the battery installation through slot for high-throughput mode (batteries meeting requirements pass freely), and offset from it for high-accuracy screening mode (only batteries meeting requirements can pass through the small gap). This dynamic positioning resolves the contradiction between reliability and productivity.

Inventive Principle:
Principle #15Dynamics

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Effectively screens batteries that do not meet model requirements, reducing the need for manual intervention and enhancing user convenience.

Implementation Method 1

the batteries to be charged in the battery installation through slot that do not meet the model requirements can, under their own gravity, pass through the screening port in the small gap formed by the incompletely connected battery installation through slot and the screening port
