Solution Overview

Problem

Users are forced to purchase multiple chargers for different portable electronic products due to varying shapes and standards, and existing chargers have poorly designed fixation structures making them inconvenient to attach and detach, limiting the ability to charge diverse electronic devices on the go.

Innovation Solution

A charger with a base and charging circuit that includes a coupling portion for detachably coupling with multiple supporting stands of different standards, allowing the same charger to accommodate various electronic products by substituting stands, and a detachable battery box system with different standards for battery charging.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If users purchase multiple chargers for different electronic products with varying standards, then each electronic product can be charged appropriately, but the number of chargers and device complexity increases

Engineering Contradiction:
Improvecompatibility with different electronic productsVSAvoidnumber of chargers
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The base of the charger is designed with a universal coupling portion that can detachably connect to supporting stands with different standards (USB Type-C, USB Type-A, Micro USB). This allows a single charger base to serve multiple electronic products with different charging interface standards, eliminating the need for multiple separate chargers and reducing device complexity while maintaining broad adaptability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Device complexity

If a fixed fixation structure is used for connecting the battery box, then the structure is simple, but the ease of operation for attachment and detachment deteriorates

Engineering Contradiction:
Improvefixation structureVSAvoidattachment and detachment convenience
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The fixation structure employs a dynamic snap-fit mechanism with elastic arms that can be easily deformed by hand pressure. When the battery box is inserted, the elastic arms automatically snap into place to secure it; when detachment is needed, simple pressure on the release portion allows the arms to flex and release the battery box. This dynamic design achieves both structural simplicity and operational ease.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If the coupling portion is designed for detachable connection, then the ease of operation for swapping supporting stands improves, but the reliability of connection may deteriorate

Engineering Contradiction:
Improveswapping supporting standsVSAvoidconnection stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The charger is segmented into a base and detachable supporting stands, each with standardized coupling portions. The coupling interface is divided into a coupling surface on the base and a corresponding coupling structure on the stand, allowing for easy separation and reattachment. This segmentation enables simple swapping while maintaining reliable connections through precise geometric fitting and snap-fit engagement mechanisms.

Inventive Principle:
Principle #1Segmentation

AI summary

The disclosure provides a charger including a base and a charging circuit. The base includes a coupling portion for detachably coupling with one of multiple supporting stands. Each of the supporting stands has a supporting container with different standards. The coupling portion has a coupling surface. The coupling surface is used for supporting one of the supporting stands. The charging circuit is disposed in the base and the charging circuit has a first electrical connector. The first electrical connector protrudes from the coupling surface. When the coupling portion is coupled with the supporting stand, a portion of the first electrical connector is disposed in the supporting container.
